Welcome back to the Tank Test Channel.... :) Update: Congratz to Kevin of West haven, UT for being randomly selected and getting this Army impact sent to him this week. Appreciate ya'll!
You've got to understand, that kit was made when the USMC had M1 tanks. You put three Marines in a room with a crow bar, and in twenty minutes someone's pregnant, someone's dead, and the crowbar is in five pieces. The tools weren't designed to give wow factor numbers. They were designed to survive the worst any crayon eater could throw at them.
That sounds about right. 😂 I have 4 USMC friends, very close friends. And yes, that pretty much sums it up.😂 They are some of the greatest friends I can ever ask for. I have very high respect for the USMC. I never served, and I decided to drive truck instead. I always told them that I will do what I can to keep America moving while you guys keep it safe.
We never used those impacts plugged into a HMMWV, they were plugged into the "Slave" outlet on the M1A1 Abrams Tank, which puts out more amps and around 28 volts. The only time we really needed to use that impact was for track maintenance, replacing track pads, replacing track sections, breaking track, and putting it back together, etc. Everything else was really just done with hand tools.
I threw one on my wrecker in an armored division just so that I can replace tires faster. operators loved hitting those finger thick thorns popping all sorts of rubber
"Pissed off gorilla in a hurry" rings so true of the few soldiers I've known. Give one of these guys a DCF961 and that Abrams track will never come off again.
For those wondering the cost, in 2005 was $2513.00 (from an old list I have). The stock number for this impact was created back in 1989, so no changes to the design since then, or it would have a new number .
Army tanker here. We always ran these off a running vehicles if we could. It isn't just that it will actually do work but these will drain the vehicle batteries quickly if you are using it for more than just one road wheel.
@@mromutt “upto 500 amps” if you do the math, that’s insanely fast. Two twelve volt car batteries have around 50 amps together in series @ 28 volts. Like the soldier said “One tire”. You have about 20 minutes of full power before you start to feel the voltage drop. That’s with healthy Battery’s. That can hold a standard CCA. Edit: I need one of these to work on cars with 😂😎
Designed to be able to yell at the closest person "grab this impact wrench and tighten these bolts as we put them in", and be confident that anyone would do the same job the same way and not strip the bolts.
So all our Bradley’s only had wrenches to do all our maintenance. Saw an abrams crew use one, got the part number from them. Cost a bottle of vodka but I got the supply sergeant to order me one. Best kept secret of my section, we’d swap track in a quarter of the time but would still be “at” the motor pool for hours.
Why did the Bradleys only get wrenches for maintenance??? Field maintenance units in armor divisions had power tools in freaking WORLD WAR II. WTF, over?!?!?
My father was a tanker in Berlin in the late 80's. Company F, 40th armor. I actually got to drive an M1 Abrams tank at the age of 17. It was pretty damn intimidating!! I maybe went 100 feet at 2 mph but it was something else being in control of a massive killing machine. Shout out to anyone from Berlin that knew SFC Price in the 40th Armored Division. He passed in 2011 from cancer due to exposure to agent orange in vietnam.
People usually think "best thing ever" when they hear "military grade" but the reality is that, in nearly all cases, it's several generations behind modern adaptations, built to an absurd spec including functioning in both the coldest and hottest places on the planet, doesnt care about atmospheric pressure, or water, and needs to be excessively reliable. To accomplish all of that manufacturers usually have to rely on tried and tested techs, none of that bleeding edge stuff (too unreliable). 10 years ago, I shit you not, there were computer systems in active service that STILL run on floppy disks... (that's the "save icon" for you really young folk)
i am in Canada and we still use stuff from the 80's. like, manufactured and started being used in the 80's... not joking. everything is dirty and smell like piss or mold. tons of stuff is patched with tape and tie-raps.
First this test is is no good. THe voltage was 4.5 volts bellow what a real military vechile would be at. 24V system would be dead at 24V just like a civilian car battery is dead at 12V. 24V system should be around 28.5V. That craptastic chinessium inverter can not do 28.5V and it's current is bellow average as well! As to computers our nuclear missel systems are ran on ancient DOS systems with slow CPU's and huge floppys. Old vintage operating systems and analog interfaces are not prone to hacking like modern systems. The computing power of a 1980's wrist watch calculator watch is more than enough to launch a missle. They are basicly operating as encypted double redundant on/off switch not a gaming PC! He might as well be powering the modern battery operated impacts off of a small laptop brick!
Two things that might be relevant here are that Abrams has something in the order of many thousands of CCA of battery :) NATO also specifies that anything that goes into one of those plugs must be able to operate on anything from 18-32V. The other things that you'll see as differerent for this versus standard impacts is that this thing is probably designed for multiple minutes of continuous usage, which would probably melt down or cause a circuit protection for a standard system :)
Yeah, the test rig set up by TTC really doesn't get close to the amps available on a tank's electrical system. Older tanks had 6 batteries, in series and parallel for 24+ volts and a ton of amps. You can't start a 'dead' tank slaved off a HMMWV - you need a lot more amps. I think 4 batteries are the minimum. It would have been interesting to see them set up an actual battery set in the same configuration as on a tank, even forgetting about the engine's alternator providing more electrical power.
@@marconiandcheese7258 Oh, no. it's looks very old and not necessarily for the military aircraftdynamics.com/products/roboimpact%C2%AE-tools/36-volt-cordless-roboimpact%C2%AE
@@TorqueTestChannel now that I think about it, 36 volts in nuron doesnt make sense since nuron is 22 volts nominal. 44 volts (if double batteries like some makitas are) would make more sense.
To clarify we didn't limit current to it on the dyno runs, footage is of us simply dialing it up little by little early on making sure we wouldn't be frying it. It was taking just over 125% of the tool's rated amps during runs.
Imagine sitting on a military $5000 toilet trying to loosen an impacted Duce of masticated MRE SOS with this beauty... does RoboImpact also make a latrine Bidet?
It is likely expensive, but not ridiculously so as the quantity delivered is enough to offset any custom tooling and R&D. The famous hammer was $435, the actual cost of the hammer was the $15 it cost to buy plus the $420 R&D and overhead. That overhead was allocated evenly across every item in the kit, so even though the it was some expensive custom electronics was where 99% of the overhead was spent on, it was allocated eventually across every item delivered. While there is waste in government procurement, generally there are reasonable explanations to a lot of the items that thrown about.
A couple notes. 1. It doesn't actually need that giant plug just for function, it's for commonality with the 'slave receptacles' that allow vehicles to jump or charge each other 2. In the clip of them working on the tank (hey, my old unit!), they're not tightening down a spring compressor, it's called a "track jack". It is a screw with a hook that goes in and out with the screw. The other hook is affixed to the body of the track jack. It is used to squeeze the track together so that you can put on the connecting linkages (center guides and end connectors) when re-connecting the track
I used to be in the USAF working on ACFT those are torq limiters they are set a predefined Torq and slip when reached it makes it easier and dummy proof for 200 lb gorillas slap one on a speed handle or a ratchet and tighten till click boom next fastener helps a lot when you have a hundred fasteners on one panel that req 225inlbs
makes me think of the time I saw a sheetrock installer their screw gun had a clutch and a magazine fed screw feeder. They could zip in a whole row in seconds.
As silly-looking as those NATO connectors are, they work extremely well in the field. Very positive connections that are likely to work after being dropped repeatedly in the mud, just so long as you shake out enough of the mud that you can actually plug the two together. And after many uses, the wallering-out of the socket doesn't cause intermittent connections until is it _obviously_ bad, like falling off completely...
@warlockd part of it has to do with EV chargers have to "talk" to the cars on board charger and make sure the correct current is being supplied, additionally that there is no isolation faults (short circuits), and all correct conditions are met safely charge. So there has to be more than just two contacts on a EV charger, both AC and DC. Lithium cells in EV batteries have a very narrow window of voltage they operate in, and exceeding it, in either direction can be very expensive, or even worse, deadly...
@@edc1569 These connectors are beefy enough to handle way, way more than 24V. I mean, they're bigger than the plugs we use for EVs right now, and have much higher contact surface area. The main reason EV companies didn't just stick 2-3 signal pins into the existing NATO design is then they wouldn't be able to license their design to other companies for profit.
I worked on government military equipment, and they set crazy specs like it has to work in crazy cold and heat up in airplane with no air pressure waterproof it is just crazy some of the specs. then the contracts are for thousands so by the time the last lots are made it is obsolete and they have a new improved model.
Also, getting a new tool approved is a whole other kettle of giant, bureaucratic fish. So...let's not build a new tool because we really, really don't want to have to go through the whole 36-month approval process.
the accuracy of your assumptions is spot on. I loved keeping one of these on a regular truck since I could just hook it straight to the NATO slave receptacle and have an extremely durable 500ish ftlb torque wrench to quickly change flats over manual tools.
I'm really surprised it uses a regular drive size for the sockets. Many military tools use odd drive sizes to discourage people from walking off with them
@@TorqueTestChannelI'm sure someone from the military will drop by and give some more information, like real world uses on the tanks and other heavy equipment.
Not sure about tank mechanics, but most mechanic units have foam cutout storage for every tool, and if at the end of the day one is missing, everything stops and noone goes home until every single socket/tool/whatever is found.
@@SvdSinner Absolutely nothing would get done over here if we had the same rule haha, I swear i had that DBE like 30 seconds ago! And who took my 10mm!?
@@TorqueTestChannelI have a corded Makita TW1000 1" drive impact, would you be interested in testing it? Mines about 10 years old but they're still being made and sold. I'd be happy to send it your way if you're interested!
It's fun to see a civilians perspective. I used these for 20 years as an Abrams crewman. The ones on the tank don't come with the tool kit which I wish it did. The bolts on the track and pads are usually rusted, damaged, or have had a 70 ton tank shove dirt into the threads, or all three. We usually have to break the bolts with a breaker bar and cheater pipe, sometimes two cheater pipes, and the accessories would have made things easier.
oh nice, they upgraded since i was in. We had giant hydraulic impacts. What a pain with 2 hydraulic lines. That slave cable adapter for power is sweet, it's the military jumper cable port
We had similar inline torque adults, in line torque wrench, it's preset and checked at pmel to certification that way G.I. types can't over torque bolts. When we installed pylons on the F-111 we used such devices. All those cylinder looking drives are inclined torque adapters, each one has its own torque setting. It won't let you over torque
Very cool tool review. I was an Armor officer and just retired with 33 years. I guess i must have been deprived as i never got to see or use this tool. When i was in Armor School, during our major Field Training Exercise, our wingman tank got mired in a bog and broke their track. We had a ton of digging by hand just to access the tracks to replace the broken links and reassemble. Everything was done with hand tool and took a grueling long time. And to make matters worse, one of the guys on our team got his ribs broke from the long prybar used while driving the tank forward and it jumped violently, breaking his ribs. From other stories, it seemed to be an all too common injury from that type of repair. We sure could have used some power tools and a recovery vehicle at that point, but it was all on human manual power. Tough lesson.
Those spline drive, slip-joint attachments are called torque adapters. Each one slips at a specified torque, as you surmised, but it's because those adapters are for the most common bolts that require specific torque, so that operator-level maintenance can be performed where a torque wrench is not available. We have smaller versions of the same thing for keeping optics evenly mounted on our precision rifles
Served on M1's for quite awhile and never had all those accessories with the impact driver. It would speed up the process of tightening or loosening bolts and worked really good with the track adjusters but to 'torque' down a road wheel bolt, you would get your 1 inch t-slide, put on the 36 inch cheater pipe, then stick on the 64 inch Tanker's bar to the end of that, then get the 2 biggest crewmen to stand and bounce on the tankers bar until it didn't move anymore. That roadwheel wasn't going anywhere. Never broke a bolt. Wedge bolts, yes, nothing else.
I’m not in the military but I was an automotive technician for 15 years until I had an accident. Those adapters you say are for “pissed off gorillas in a hurry” look to be torque limiters. We use less engineered ones in the automotive word and call them “torque sticks”. You can hurry up and torque things or just make sure you don’t over torque things. Very handy for rookies and when you don’t wanna have to use a torque wrench.
That impact is for vehicle operators to do things like charge track pads or reset a thrown track in the field. Mechanics have a hydraulic port on the wrecker for a hydraulic impact that can go to over 1000 ft lbs. Operators aren't highly skilled - drivers are the only job with lower entry requirements than cannon fodder... They break enough stuff without power tools...
Makes sense the average grunt doesn't get the really powerful tools. "If it ain't broke, it hasn't been issued to the infantry." Would appear to be the appropriate adage here.
Our company bought about 100 of these, although ours used Milwaukee batteries, at a cost of $4,000 a piece. They were used to drill utility poles. Almost all of them the motors burned out. The company refused to fix them, saying we abused them, their proof being the motors burned out. We ended up throwing them away and replacing them with hilti and Milwaukee impacts. .
When I was in the Army the first time in the early 80's we had a few hand and hammer driven tools for the Jeeps and the 2 1/2's. The last time I was in we had all Humvees and 5 tons. I never saw that tool, but I am sure we had them in the supply storage. That is a cool tool. If you had it all set up with the battery and stuff. Good find.
I am a lifelong Auto Mechanic and a Military History junkie this is one of the coolest things I've ever saw. I had no idea a Humvee could provide electricity like that.
This thing was probably designed in the 70's. That makes it way more impressive. I love the one-way torque limiting feature. That would be nice in a consumer tool. You can lean on it without worrying about damaging things.
Designed in the '80s alongside the torque specs for the M1A1 track components, which is also why it has slip clutch accessories that slip at a certain torque. Basically idiot-proof considering drivers are one of the lowest entries in field service. M1s and Humvees shared a 28v port, M1s had higher amps out of that port, the tool is for field service of basically only track service. If you want to look at an actual general purpose tool, Humvees would also have a hydraulic port for hydraulic tools.
that stuff breaks on its own because the maintenance crews are now special hire pronoun warriors. No worries as an overpriced replacement item is just wat the MIC ordered 😅
Coming from a former armored crew member in 2nd armored division. That torque multiplier is not for untightning or breaking bolts free. Its preset torque is for tightning wedge bolts on the track. A torque wrench gets easily damaged in the sponson boxes. There is one torque wrench per platoon. Its 3/4 drive for mainly sprockets amd road wheela
I am holding out that one day I will see a 2-1/2" drive, or even a 3-1/2" drive pneumatic setup apprar on this channel. When the torque numbers start to break the 40k ft/lb mark things become a lot more interesting.
@@sshep7119 Tools like that are awesome just for the owner's manuals! "Portable and easy to handle" is what it says on the website, but the manual says "This tool is designed to be operated by a minimum of two persons."
I can't imagine it is easy to bench test an impact that puts out 80,000 ft/lbs of torque and weighs 600lbs. I looked up the biggest socket I could find and the socket itself is 43lbs, of course that is a 9-3/4" socket. There is a few youtube videos of the IR599 being used and it just sounds like you would expect it to.
@@chrisdavidson911 Yeah, the IR599A1 weighs well 599lbs. A minimum of 2 guys, plus the crane operator and a spotter. Still would be one hell of an episode if TTC could make it happen, there is a 599A1 on the bay right now for 16K but that doesn't include a socket. The socket alone is about $2500.00 for the smallest socket I could find for it.
While running, a 24V vehicle will be at 27-28V just as a 12V vehicle gets 13.8-14V while running. You can't charge a battery without a higher voltage, so it makes sense that this tool worked "properly" at what would be a normal running voltage.
rember, they know what the torque specs on every part of that tank are. they don't want to give them something that is overpowered, they know the 19 year old kid doing the work is going to lay on the trigger way too long, so with these kind of numbers, you're never going to get into real trouble where a big breaker bar can get you out of
Never knew this thing had an entire kit. The impact is usually just thrown in a bag somewhere and the rest of the kit is lost. Also the impact is usually broken or still too weak to do anything.
My wife hears this in the background and asks in a confused voice; what are you watching? I say; something that would bore the f*** out of you but is fascinating the f*** out of me. She laughed
It's 11:30PM in my country. > I am working from home. > I have NO interest in impact wrenches. > Found this video. > Still watched. > I think I'll take a 14 minute break.
They are good in a pinch, we were doing sprockets onetime. Those bolts are like 1-1/2 inch head size and are torqued to around 750 foot pounds. Ended up using my 1/2 drive Milwaukee with a 1/2 to 3/4 adapter and socket. It zipped them right out with little fuss, to this day I still abuse that Milwaukee for track maintenance and it hasn’t broken yet while the issued impact still sits packed away in the sponson box on the tank.
I've seen a few comments regarding old tech used in army. I just wanted to add that the US army still uses an extended support version of windows XP (yes, the OS from 2001) because it was tried and tested and reliable and most importantly secure (when something is mass adopted AND that old it usually means there are very, very few zero-day vulnerabilities left)
It still works! It's inefficient but the army bought it and changing it over is a bigger deal than one would normally think it is. Plus, from my understanding, USA was really gearing to go to war with the soviet union in the 80s-90s. So they bought up tons of gear to be ready. And it's been in inventories ever since and every change of command is the dreaded full inventory lay out for stuff that hasn't been touched since the last inventory lay out.
I used to be friends with a guy who's first job was Information and Communications in the Airforce. When he started, in 1999, they were just starting to implement Windows NT on servers. They were still using OS/2 from 1987 and he said there was a entire room stacked floor to cieling of old IBM 386's that were *top of the line* in 1985.
Simple, robust, and reliable. Even patient workers make mistakes, and designing your workflows and tools to minimize the chances of failure is smart. I love that giant connector too.
You need to remember, most military service equipment is serviced more often than its used. Theres no scenario with rusted or seized fasteners. Everything should come apart fairly easily.
This is what really sets the US military apart from other military's. The fact that we have such a strong NCO core and that we actually maintain our equipment.
Great video, you guys crack me up. Like a lot of the other commenters said, the Government has something under contract, it keeps it (forever), and probably more important of all, something that will work by a non-mechanic in extreme conditions (heat, cold, snow, mud, sand, water, under fire, etc.)
Those attachments are torque limiters. We use them on things all the time in the airforce. Basically a fixed "torque wrench" you'll use for a specific job.
about 20 years ago i bought a us military surplus variable speed hydraulic motor . it came hermetically sealed in foil and packed in a fine layer of grease inside. very similar to your package with the airtight foil bag sealed to prevent corrosion. seems that is pretty standard for how spare parts are packed for the military.
All the recovery vehicles I have ever been in typically output 28 volts. With that said both of the FSCs I have been in just have the big ass Milwaukee cordless impacts
These impacts get the sockets so hot when replacing track. We routinely kept three on hand and would cool them off in water. 1600 on a Friday here comes a flat bed with a platoons worth of track. 😅
Got a buddy in the 5th Armored who, with some friends in the motorpool, designed adapters to charge battery packs off the NATA plugs and tossed DeWalt gear into their field kits. ;)
I worked as a contractor on military bases for years, and they will overpay by like 10x to install only made in the USA materials even if there's a massively cheaper and superior product made outside the US. It actually started getting difficult even finding some things that were even made in the US some times.
The problem with buying cheaper overseas stuff is that once it happens the US factory closes up shop and if things in the world really gets hot again then your supply chain is potentially cut off with no domestic supply available at all. Imagine WWII but all our stuff was made in China...It wouldn't have worked out so well for us.
first saw those as a new tanker in 1994. Was part of the M1 BII (basic issue inventory) initially the warehouse didn't want to give them to us, said we'd just wreck them. The mechanics were jealous of how light and easy to use it was compared to the hydraulic operated impacts on the M88 recovery vehicles. Never saw one in a box like that, only in a green canvas bag. 1000% better on track jacks or building new track from sections with end connectors and center guides needing to be attached than hand tools.
Its cool to see someone do a video on these after looking into them myself. I was going to adapt one to accept 40-48v off of a tool battery (likely ryobi 40v) but never went thru with it because of a back injury at the time. Im all healed up now and i really wish I had done it, the prices were seemingly much better then
F1 cars use torsion bars for the exact same reason as tanks. F1 uses them because of the insane weight applied to them from downforce and cornering and they can use just a few of them, whereas a tank needs a lot of them because it's just heavy. Conventional spring suspension is not good enough.
Some of the army surplus and equipment I've gotten to use and disassemble reminds me of the old Soviet hardware - it will run like shit being used under fire longer than most hardware will run at all. The far more common requirement military equipment is looking for is the ability to perform consistently and *predictably* in high variable environments, and the manufacturer is required to guarantee the military that they will carry replacement parts for decades after a contract. Also, it's not low-intelligence, it's high-panic and something so simple that us with our animal brains fully engaged while under fire with everything going wrong. This is why there's still hesitation by many procurement for off-the-shelf civilian stuff.
This isn't peak. The tool is meant specifically for track service on the M1A1, hence all the torque limitations on the accessories, and hence why the tool itself hasn't changed since the '80s. If you want to see peak with a military tool, just wait until they get the hydraulic wrenches, which were used in the same sense that any other tool on this channel is realistically used as.
During 19k osut at Fort Knox, we used one for about 10 seconds and it burned out and broke. We then learned how to use a ratchet, socket, and breaker bar to remove track links.
@0:28 that vehicle is about two miles from my house. I can take a picture from the road lol. Where did you guys get this footage? Did the PAO dorks put this on Facebook?
Growing up I remember hearing the phrase "make sure that hummer is running" to imply working at maximum capacity. I never made the connection until today. Thanks, army slang!
The improvement at 28v makes sense, “24v” aircraft systems really operate at 28vdc after the generators are one. Probably the same thing with the NATO standard, 24v is the voltage on battery power.
The second test with higher voltage gave better result because the tool was able to use higher power. Based on the rating of that connector, the tool could use up to 4000 Watts of power (24 Volt x 500 Amp = 12000 Watts, with Military safety factor is usually 3, so it's about 4000 Watts). However, the power available to the tool was limited to less than 1000 Watts (power supply power rating). A better power source would be 2 car batteries in series. They will supply instantaneous current up to hundreds of amps.
You should try to get your hands on one of those fabled $500 wrenches that the contractors constantly charge the taxpayers for. Or the one from smedley Butler's book that apparently worked on a single nut in the entire country
Brilliant! Please consider testing the old Porter-Cable/Rockwell 548 Jig Saws compared with the new style ones. they were industrial grade, had bronze worm drives (awesome torque at lower speeds) i own 3 of them and love them
I have to add my two cents worth as a retired 19K10 Abrams Tank Crewman. We never saw these on our tanks. We heard about them but never saw them. This is mid 90's to early 2k. What we had besides our brute force was Little Joe if we were cool with the Maintenance guys and if a M88 was near by. The ten times I had to break track was all by hand.
As the son of a man who drove trucks in and out of the United States Army, the starting voltage for commercial, civilian road tractors is 24 V D,. The A4 V DC system is on DoD trucks including the moded road tractors such as the Freightliner FLDs found in some reserve units as well in many National Guards.
the connector is a universal plug. it is used to power things but also to be powered by something. so you can use tools with it or jumpstart a tank or other vehicle with it. funny side note you can start a tank in theory with a small car and a normal jumper cable if you have access to the battery.
Welcome back to the Tank Test Channel.... :)
Update: Congratz to Kevin of West haven, UT for being randomly selected and getting this Army impact sent to him this week. Appreciate ya'll!
Super cool kit guys, thanks for the video. Still super interested in hearing your thoughts on the new Powerpack DW batteries...cheers
I have an army buddy that used to work on tanks, which was his specialty. I would love to show him this and see if he remembers.
Would love to have one of those wrenches to go with our m939 5 ton truck, it would work great for changing tires.
That would be pretty impressive to wield at a jobsite, I tell you what
Not to sound dumb but is buying the Xcel file on Etsy how we help support the channel (and enter for a chance to own that beast of a tool) ?
You've got to understand, that kit was made when the USMC had M1 tanks. You put three Marines in a room with a crow bar, and in twenty minutes someone's pregnant, someone's dead, and the crowbar is in five pieces. The tools weren't designed to give wow factor numbers. They were designed to survive the worst any crayon eater could throw at them.
I resemble that remark. Tanker from '85 - '91 on the M60A1's. We can find a way to break anything. But in the end we find a way to fix it.
That sounds about right. 😂
I have 4 USMC friends, very close friends. And yes, that pretty much sums it up.😂
They are some of the greatest friends I can ever ask for. I have very high respect for the USMC.
I never served, and I decided to drive truck instead. I always told them that I will do what I can to keep America moving while you guys keep it safe.
You know, that exact same phenomenon occurs when you place three underground miners in a room with pretty much any hand tool :-)
If it ain't broke, it hasn't been issued to the infantry.
We just used 3/4 ratchets and breaker bars with 3 foot long cheater pipes on them in the Army when I was in. We had just gotten the M1.
We never used those impacts plugged into a HMMWV, they were plugged into the "Slave" outlet on the M1A1 Abrams Tank, which puts out more amps and around 28 volts. The only time we really needed to use that impact was for track maintenance, replacing track pads, replacing track sections, breaking track, and putting it back together, etc. Everything else was really just done with hand tools.
I threw one on my wrecker in an armored division just so that I can replace tires faster. operators loved hitting those finger thick thorns popping all sorts of rubber
Sounds like the engineers designed it to work ideally at exactly the correct voltage then, going by the tests in the video.
I was about to comment about the bank of series parallel batteries in the Abrams that this tool is plugged into
And 3 out of the 4 in your platoon would always be broken
@@mr.mayhem9724 yea right, like any motorpool i was in had even 1! let alonne 4!! lmao
"Pissed off gorilla in a hurry" rings so true of the few soldiers I've known. Give one of these guys a DCF961 and that Abrams track will never come off again.
Or, just as likely, that Abrams track will never go on again :)
So you're saying the Marines could use this too?
@@svideodotorgIt should be considered "Marine Resistant", there is nothing that can actually be rated to survive US Marines
@@Man_Emperor_of_Mankind It's like my mom always said. "You can design an idiot proof item, but nature will design a better idiot in response."
This is how you get your fingers broken
For those wondering the cost, in 2005 was $2513.00 (from an old list I have). The stock number for this impact was created back in 1989, so no changes to the design since then, or it would have a new number .
150-200 used on ebay
Which means this is the pinnacle of 1980 (not 1980s) technology. haha
Look at the competition in 1989. Yes, this was a MONSTER of a tool.
So x12 more than it should cost. Sounds about right.
Updated items can keep the same number, provided that there is no significant change in form, fit, or function.
Army tanker here. We always ran these off a running vehicles if we could. It isn't just that it will actually do work but these will drain the vehicle batteries quickly if you are using it for more than just one road wheel.
If only it had an adapter to pop the bitch plate off lol.
haha I was kind of thinking about that. In the back of my head I was wondering how fast it would drain the batteries if they were not running.
@@mromutt “upto 500 amps” if you do the math, that’s insanely fast. Two twelve volt car batteries have around 50 amps together in series @ 28 volts. Like the soldier said “One tire”. You have about 20 minutes of full power before you start to feel the voltage drop. That’s with healthy Battery’s. That can hold a standard CCA.
Edit: I need one of these to work on cars with 😂😎
Would’ve been a more accurate test if they at least plugged it into a running generator.
@@AgedFactual 500A is just the plug rating. It seemed to draw more like 30A.

When I went thru basic in the Army we had 5 Tanker guys in the platoon, all 5 were knuckle draggers.
So all our Bradley’s only had wrenches to do all our maintenance. Saw an abrams crew use one, got the part number from them. Cost a bottle of vodka but I got the supply sergeant to order me one. Best kept secret of my section, we’d swap track in a quarter of the time but would still be “at” the motor pool for hours.

My father was a tanker in Berlin in the late 80's. Company F, 40th armor. I actually got to drive an M1 Abrams tank at the age of 17. It was pretty damn intimidating!! I maybe went 100 feet at 2 mph but it was something else being in control of a massive killing machine. Shout out to anyone from Berlin that knew SFC Price in the 40th Armored Division.

People usually think "best thing ever" when they hear "military grade" but the reality is that, in nearly all cases, it's several generations behind modern adaptations, built to an absurd spec including functioning in both the coldest and hottest places on the planet, doesnt care about atmospheric pressure, or water, and needs to be excessively reliable. To accomplish all of that manufacturers usually have to rely on tried and tested techs, none of that bleeding edge stuff (too unreliable). 10 years ago, I shit you not, there were computer systems in active service that STILL run on floppy disks... (that's the "save icon" for you really young folk)
I have some bad news. Bunch of the cools stuff still runs on 8" floppy.
To my most recent recollection there were still missle silos relying on Floppy's, but that may have changed
Fun fact: In today’s world, old school floppy based computers provide (be it accidentally) air gap protection from network hacks.
i am in Canada and we still use stuff from the 80's. like, manufactured and started being used in the 80's... not joking. everything is dirty and smell like piss or mold. tons of stuff is patched with tape and tie-raps.
First this test is is no good. THe voltage was 4.5 volts bellow what a real military vechile would be at. 24V system would be dead at 24V just like a civilian car battery is dead at 12V. 24V system should be around 28.5V. That craptastic chinessium inverter can not do 28.5V and it's current is bellow average as well! As to computers our nuclear missel systems are ran on ancient DOS systems with slow CPU's and huge floppys. Old vintage operating systems and analog interfaces are not prone to hacking like modern systems. The computing power of a 1980's wrist watch calculator watch is more than enough to launch a missle. They are basicly operating as encypted double redundant on/off switch not a gaming PC! He might as well be powering the modern battery operated impacts off of a small laptop brick!
Two things that might be relevant here are that Abrams has something in the order of many thousands of CCA of battery :) NATO also specifies that anything that goes into one of those plugs must be able to operate on anything from 18-32V.
The other things that you'll see as differerent for this versus standard impacts is that this thing is probably designed for multiple minutes of continuous usage, which would probably melt down or cause a circuit protection for a standard system :)
Yeah, the test rig set up by TTC really doesn't get close to the amps available on a tank's electrical system. Older tanks had 6 batteries, in series and parallel for 24+ volts and a ton of amps. You can't start a 'dead' tank slaved off a HMMWV - you need a lot more amps. I think 4 batteries are the minimum. It would have been interesting to see them set up an actual battery set in the same configuration as on a tank, even forgetting about the engine's alternator providing more electrical power.

In a world where the government spends $12,000 on a hammer I'd like to see what they pay for this spinny boi.
All I care about is that it works when it needs to on the battlefield.
It is likely expensive, but not ridiculously so as the quantity delivered is enough to offset any custom tooling and R&D.
The famous hammer was $435, the actual cost of the hammer was the $15 it cost to buy plus the $420 R&D and overhead. That overhead was allocated evenly across every item in the kit, so even though the it was some expensive custom electronics was where 99% of the overhead was spent on, it was allocated eventually across every item delivered.
While there is waste in government procurement, generally there are reasonable explanations to a lot of the items that thrown about.

A couple notes.
1. It doesn't actually need that giant plug just for function, it's for commonality with the 'slave receptacles' that allow vehicles to jump or charge each other
2. In the clip of them working on the tank (hey, my old unit!), they're not tightening down a spring compressor, it's called a "track jack". It is a screw with a hook that goes in and out with the screw. The other hook is affixed to the body of the track jack. It is used to squeeze the track together so that you can put on the connecting linkages (center guides and end connectors) when re-connecting the track

As silly-looking as those NATO connectors are, they work extremely well in the field. Very positive connections that are likely to work after being dropped repeatedly in the mud, just so long as you shake out enough of the mud that you can actually plug the two together. And after many uses, the wallering-out of the socket doesn't cause intermittent connections until is it _obviously_ bad, like falling off completely...
Stick a screwdriver in it and pinch the outer ring. It would go again.
Makes me wonder why a similar design wasn't used for EV's You have connectors and specs out there already.
@warlockd part of it has to do with EV chargers have to "talk" to the cars on board charger and make sure the correct current is being supplied, additionally that there is no isolation faults (short circuits), and all correct conditions are met safely charge. So there has to be more than just two contacts on a EV charger, both AC and DC. Lithium cells in EV batteries have a very narrow window of voltage they operate in, and exceeding it, in either direction can be very expensive, or even worse, deadly...
@@warlockdevs need a bit more than 24V, so you the requirements are totally different.
@@edc1569 These connectors are beefy enough to handle way, way more than 24V. I mean, they're bigger than the plugs we use for EVs right now, and have much higher contact surface area.
The main reason EV companies didn't just stick 2-3 signal pins into the existing NATO design is then they wouldn't be able to license their design to other companies for profit.
I worked on government military equipment, and they set crazy specs like it has to work in crazy cold and heat up in airplane with no air pressure waterproof it is just crazy some of the specs.
then the contracts are for thousands so by the time the last lots are made it is obsolete and they have a new improved model.

It's fun to see a civilians perspective. I used these for 20 years as an Abrams crewman. The ones on the tank don't come with the tool kit which I wish it did. The bolts on the track and pads are usually rusted, damaged, or have had a 70 ton tank shove dirt into the threads, or all three. We usually have to break the bolts with a breaker bar and cheater pipe, sometimes two cheater pipes, and the accessories would have made things easier.

Very cool tool review. I was an Armor officer and just retired with 33 years. I guess i must have been deprived as i never got to see or use this tool.
When i was in Armor School, during our major Field Training Exercise, our wingman tank got mired in a bog and broke their track. We had a ton of digging by hand just to access the tracks to replace the broken links and reassemble. Everything was done with hand tool and took a grueling long time. And to make matters worse, one of the guys on our team got his ribs broke from the long prybar used while driving the tank forward and it jumped violently, breaking his ribs. From other stories, it seemed to be an all too common injury from that type of repair.
We sure could have used some power tools and a recovery vehicle at that point, but it was all on human manual power. Tough lesson.
Those spline drive, slip-joint attachments are called torque adapters. Each one slips at a specified torque, as you surmised, but it's because those adapters are for the most common bolts that require specific torque, so that operator-level maintenance can be performed where a torque wrench is not available. We have smaller versions of the same thing for keeping optics evenly mounted on our precision rifles
Served on M1's for quite awhile and never had all those accessories with the impact driver. It would speed up the process of tightening or loosening bolts and worked really good with the track adjusters but to 'torque' down a road wheel bolt, you would get your 1 inch t-slide, put on the 36 inch cheater pipe, then stick on the 64 inch Tanker's bar to the end of that, then get the 2 biggest crewmen to stand and bounce on the tankers bar until it didn't move anymore. That roadwheel wasn't going anywhere. Never broke a bolt. Wedge bolts, yes, nothing else.

That impact is for vehicle operators to do things like charge track pads or reset a thrown track in the field.

Operators aren't highly skilled - drivers are the only job with lower entry requirements than cannon fodder... They break enough stuff without power tools...

I am a lifelong Auto Mechanic and a Military History junkie this is one of the coolest things I've ever saw. I had no idea a Humvee could provide electricity like that.
This thing was probably designed in the 70's. That makes it way more impressive. I love the one-way torque limiting feature. That would be nice in a consumer tool. You can lean on it without worrying about damaging things.
Designed in the '80s alongside the torque specs for the M1A1 track components, which is also why it has slip clutch accessories that slip at a certain torque. Basically idiot-proof considering drivers are one of the lowest entries in field service. M1s and Humvees shared a 28v port, M1s had higher amps out of that port, the tool is for field service of basically only track service. If you want to look at an actual general purpose tool, Humvees would also have a hydraulic port for hydraulic tools.

While running, a 24V vehicle will be at 27-28V just as a 12V vehicle gets 13.8-14V while running. You can't charge a battery without a higher voltage, so it makes sense that this tool worked "properly" at what would be a normal running voltage.

They are good in a pinch, we were doing sprockets onetime. Those bolts are like 1-1/2 inch head size and are torqued to around 750 foot pounds. Ended up using my 1/2 drive Milwaukee with a 1/2 to 3/4 adapter and socket. It zipped them right out with little fuss, to this day I still abuse that Milwaukee for track maintenance and it hasn’t broken yet while the issued impact still sits packed away in the sponson box on the tank.
I've seen a few comments regarding old tech used in army. I just wanted to add that the US army still uses an extended support version of windows XP (yes, the OS from 2001) because it was tried and tested and reliable and most importantly secure (when something is mass adopted AND that old it usually means there are very, very few zero-day vulnerabilities left)
It still works! It's inefficient but the army bought it and changing it over is a bigger deal than one would normally think it is. Plus, from my understanding, USA was really gearing to go to war with the soviet union in the 80s-90s. So they bought up tons of gear to be ready. And it's been in inventories ever since and every change of command is the dreaded full inventory lay out for stuff that hasn't been touched since the last inventory lay out.
I used to be friends with a guy who's first job was Information and Communications in the Airforce. When he started, in 1999, they were just starting to implement Windows NT on servers. They were still using OS/2 from 1987 and he said there was a entire room stacked floor to cieling of old IBM 386's that were *top of the line* in 1985.
Simple, robust, and reliable. Even patient workers make mistakes, and designing your workflows and tools to minimize the chances of failure is smart. I love that giant connector too.
You need to remember, most military service equipment is serviced more often than its used. Theres no scenario with rusted or seized fasteners. Everything should come apart fairly easily.
This is what really sets the US military apart from other military's. The fact that we have such a strong NCO core and that we actually maintain our equipment.
Great video, you guys crack me up. Like a lot of the other commenters said, the Government has something under contract, it keeps it (forever), and probably more important of all, something that will work by a non-mechanic in extreme conditions (heat, cold, snow, mud, sand, water, under fire, etc.)

F1 cars use torsion bars for the exact same reason as tanks. F1 uses them because of the insane weight applied to them from downforce and cornering and they can use just a few of them, whereas a tank needs a lot of them because it's just heavy. Conventional spring suspension is not good enough.

The far more common requirement military equipment is looking for is the ability to perform consistently and *predictably* in high variable environments, and the manufacturer is required to guarantee the military that they will carry replacement parts for decades after a contract.
Also, it's not low-intelligence, it's high-panic and something so simple that us with our animal brains fully engaged while under fire with everything going wrong. This is why there's still hesitation by many procurement for off-the-shelf civilian stuff.
I really thought, that NASCAR gun was peak TTC.
I was wrong.
This isn't peak. The tool is meant specifically for track service on the M1A1, hence all the torque limitations on the accessories, and hence why the tool itself hasn't changed since the '80s. If you want to see peak with a military tool, just wait until they get the hydraulic wrenches, which were used in the same sense that any other tool on this channel is realistically used as.
During 19k osut at Fort Knox, we used one for about 10 seconds and it burned out and broke.
We then learned how to use a ratchet, socket, and breaker bar to remove track links.
@0:28 that vehicle is about two miles from my house. I can take a picture from the road lol. Where did you guys get this footage? Did the PAO dorks put this on Facebook?
Growing up I remember hearing the phrase "make sure that hummer is running" to imply working at maximum capacity. I never made the connection until today. Thanks, army slang!
That old saying: "If it ain't broke....don't break it!"
If it ain't broke, fix it until it is
I’ve used those all the time when I was in the Army. We always had the vehicle running supplying 28 volts
Awesome vid man! My best investment was your Tool Rankings chart! Has saved me hundreds of dollars.
The improvement at 28v makes sense, “24v” aircraft systems really operate at 28vdc after the generators are one. Probably the same thing with the NATO standard, 24v is the voltage on battery power.
I don’t watch a lot of the torque channel. But I almost broke my phone, trying to hit the when I read the title
I love how you guys buy stuff just to test stuff and prove it does or doesn’t meet expectations!
Really wishing I owned the rank charts right now 😥
We don't pick a winner for another month or so
@@TorqueTestChannelwhere do I get the rank chart?
@HandyMann243 if only there was a place for information like that RIGHT ON THIS PAGE.
The second test with higher voltage gave better result because the tool was able to use higher power. Based on the rating of that connector, the tool could use up to 4000 Watts of power (24 Volt x 500 Amp = 12000 Watts, with Military safety factor is usually 3, so it's about 4000 Watts). However, the power available to the tool was limited to less than 1000 Watts (power supply power rating). A better power source would be 2 car batteries in series. They will supply instantaneous current up to hundreds of amps.
You should try to get your hands on one of those fabled $500 wrenches that the contractors constantly charge the taxpayers for. Or the one from smedley Butler's book that apparently worked on a single nut in the entire country
this was AWESOME. Let's hope the staff at one of the Iowa class museum ships finds their version to loan you for a face-off.

Brilliant! Please consider testing the old Porter-Cable/Rockwell 548 Jig Saws compared with the new style ones. they were industrial grade, had bronze worm drives (awesome torque at lower speeds) i own 3 of them and love them
I have to add my two cents worth as a retired 19K10 Abrams Tank Crewman. We never saw these on our tanks. We heard about them but never saw them. This is mid 90's to early 2k. What we had besides our brute force was Little Joe if we were cool with the Maintenance guys and if a M88 was near by. The ten times I had to break track was all by hand.
As the son of a man who drove trucks in and out of the United States Army, the starting voltage for commercial, civilian road tractors is 24 V D,. The A4 V DC system is on DoD trucks including the moded road tractors such as the Freightliner FLDs found in some reserve units as well in many National Guards.
the connector is a universal plug. it is used to power things but also to be powered by something. so you can use tools with it or jumpstart a tank or other vehicle with it. funny side note you can start a tank in theory with a small car and a normal jumper cable if you have access to the battery.
