The OLD Skid Steer SMOKES Like a Chimney!!! Let's Find out WHY! ~ 1995 Gehl 5625sx Skid Loader P2

- Опубліковано 12 чер 2024
- From the day I rescued this skid steer, the Perkins Diesel engine has run FLAWLESSLY, until now!
For some reason the machine has become really hard starting and has started smoking A LOT. That in turn has cause a loss in power and so I've decided that we need to figure out what's going on before something much worse happens!
So the plan today is to start diagnosing the issue so we can figure out what we need to fix to correct these issues!
Sit back, relax, and enjoy everything we have to do to work our way through the fuel system and try and figure out what is causing this old Gehl to run SO poorly!

That dog is only a couple hundred hours away from turning 30, and it fell into the right hands to get another 30 years. I admire your old school approach, how you peel back layers on all of your projects. Under adverse conditions, yeah, throw in a new pump and work your way out to getting it running asap, but these are your tools, and this is your hobby. It's more than a tool, it's a part of an entire collection of equipment that others wrote off as no longer useful. Keep up the good work, and keep making these great video's.
When cranking the engine over the filters are on the suction side and will not bleed fuel. Opening them will introduce air into fuel lines and pump while cranking.
I would have checked the glow plugs first of all with a hard start.
The reason you water separator has no fuel purging out is because it’s on the suction side of the pump if you were to remove that filter you would find it is nearly empty ( unless stopped up). The glow plugs will cause a hard start but wouldn’t cause the smoke your getting once it’s running. I did hear the fuel knock that is common with fuel leak down. We also know it’s between the pump and injectors because the secondary fuel filter was full when removed. One more thing to look for is a check valve on the return side. This valve allows the fuel system to build primary fuel pressure. Trash will cause the valve to stick an drain fuel back into the tank.
I agree with everything you said! I didn't think about the check valve on the return side... I'm not sure where it is on this machine... I'll have to take a look, thanks for the idea!
love watching you . The small skid steere came out great. You have to start protecting your hands.
Well now you got me curious as to what is causing the problem... guess I'll have to wait for the next upload. Been enjoying your channel a bunch and glad to see you with a great renovated and improved space to work.
It's the joys of being a mechanic and finding out what's wrong that's causing all the issues. Good job figuring it out.
I really admire your patience, working through each process is so time consuming but in most cases the best way to find a problem. Looking forward to the next one to see episode. 🤗👍
We'll I'd rather figure it all out now and not worry about it later! Thanks for the support Everest! I truly appreciate it!
"it feels a little better prying, not too much..." next we see the hammer, too funny but I sure do appreciate what you are doing and really admire your patience and expertise! Thank You!
I love these videos that show you fixing stuff. I always end up learning cool things.
This is getting interesting, one thing for sure is when your done and the issue resolved, you definitely are going to know what you have for a machine and you will also know it’s going to be reliable, I like the the systematic approach to the identifying the issue. Thanks for the video young man, I am enjoying the process.
That is one reason I'm all for diving a bit deeper than most people might... after I fix all the misc small things and do the maintenance it'll be good for a LONG time!
I really enjoy your videos and I've been really inspired by your shop build. Thanks for putting all the efforts into your videos. Top notch!
Glad to see you're back doing what you do best. Saving gear from the metal scrapyard. I'm hanging-out to see you put the Gehl back together and turn the key.
You sure did a lot of work for cold-starting issue.... without ever testing that the GLOWPLUGS are getting power. Those older engines NEED some GP operation even during summer cold starts.
I can see why you might think that, but glow plugs don't effect the engine when it's running... im more concerned with why it's smoking and figuring that issue out, than if the glow plugs are helping out with cold starts... ive NEVER used the glow plugs on this machine, but we will be getting into them later!
@@SalvageWorkshop Glow plugs are much more important than you think
Agreed, I even have to glow plug diesel lawn mowers on warm days.
Glowplugs are not that important on most engines if its not just pretty cold. Some older machines dont even have them! But there are some engines that just wont do anything even on a warm day without a glow! (Like kubota) its to simple to say that all diesels need good glow! Its just not true... really depends on the engine some do some dont
@mitsubishi garage I agree I worked on Hercules diesel engines in the USAF.. 4 and 6 cylinder, no glow plugs .. and don't get caught using ether
Great video. Lot of work! Enjoyed watching 👍🏼
Dude, you left us with a cliffhanger! I'm really looking forward to the cleanup/disassembly/reassembly of that fuel pump. Keep em' coming, SW!
Yeah, but there was NO way I could get it all fit into that one video! Have no fear, you'll enjoy the next one too!
I really like your approach and friendly style, love the restorations a bit more but also the engine stuff and I'm slowly getting there to understand some motor stuff! tnx!!
Great video,thanks for taking the time and effort to share it with us.
When i first saw you cranking that little skid steer up, i could see that the glow plugs are the most likely culprit for it not starting very well when its cold. lots of white smoke is a sure fire sign that theyre not working, along with hard starting. Since its more of a traditional diesel engine with a mechanical pump, rather than a modern common rail diesel injection sytem
I agree, I bought a used skid steer and had trouble starting it until I discovered I wasn't turning on the glow plugs. When starting old Cats with pony motors, white smoke always meant too cold.
I had the same thought. Also because this issue is apparently jet wash related. Only thing against this theory would be that it would remain running tough. Normally when glow plugs are the issue, the smoke clears up after a minute or so.
@dirkrussel yeah, its possible there are other issues as well. Possible water ingress into a relay or corroded wires that got knocked off with the pressure washer too. I did notice in the previous video that it was smoking pretty bad, but only seemingly at random
I have never used the glow plugs on this machine, and it started having this issue in the fall and Temps outside were still in the 60-70' F... we will get into the glow plug system, but only after we deal with the problem
Injection pumps can always be nerve racking especially when you're not sure what you're doing. I had the same issue on my old 4500 industrial. Area diesel was a big help. They're good people. Good luck. Looking forward to the next video.
Really like these search n resurrect videos, aka troubleshooting .
You have many here armchair quarterbacking.
Everyone's wants the same thing.
Good stuff, Thanks Matt 😊
Great job working on
the skidsteer. I kind like
the process of one thing
at a time at least you
know that that item has
been changed. After
all you have got to make
a video. Keep up the
good work MATT.
I bought a non start HMMWV at auction. Put on the two missing tires , pulled it off the delivery flatbed added 5 gallons of fuel. It was very low if not out of fuel. Plus cranked and cranked. White smoke finely fired up. It needed all 8 glow plugs and the smart start box, ie the glow plug controller. She's all good now.saved a boat load of money.
I can see that! That doesn't fix my smoking while running issue, which is more concerning to me than the hard starting issue!
You normally seem to work through problems, one step at a time and eventually find the cause, even if there may be obvious possibilities that you overlook at first. The good thing about this approach is that very often you clean up other future problems as you go thus saving you headaches later. I've no doubt you will sort this in the next episode and by then, fuel issues are unlikely to cause any issues for years to come. Good stuff and much more enjoyable than watching building work if you don't mind me saying.
Should be maintained before you do any fabrication, I hope you solve the issues with the skid steer! Looks like a pretty good piece of equipment brother!
Patience of a saint
Back in the early nineties I was a Peugeot Technician at the Main Dealer. I havent read any of the comments below. It was my experience that despite checking that there no air leaks, no fuel leaks, The Diesel Stop solenoid worked correctly from the ignition switch, the Heater Plugs (individually) worked by connecting a wire to the terminal, holding the body with some pliers to earth and connect the other end of the wire to the Positive terminal on the battery, within 12 seconds the plug should being glowing red hot (it will only take 2 to be faulty and the engine will not start) and also the Heater Plug Relay, and the supply wire from the Relay to the Heater Plugs was ok.
The non running non starting was simply that the Valves had recessed into the valve seats so much so, that the valves were actually being held open, Check your valve gaps !!
Another great looking time 👍👍
You need to pull all the glow plugs. Inspect them, then test for their resistance. They should have an ohm spec. Also test each glow plug wire for power with the switch on. You can't tell if a glow plug is bad by just looking at it. I've seen bad plugs new out of the box. Test them all.
Yeah, we'll dive into that after we fix the smoking while running issue!
@@SalvageWorkshop If the low plugs are not working it will take forever to start if it starts at all, and then with a lot of gray smoke. Check em now not later on.
You are pouring unburnt diesel into the engine whilst starting, possibly to the detriment of the rings, bores etc. Check and or change the glow plugs, they are not expensive on Amazon, well known Bosch or NGK brands.
By god, I think yer gunna get it.
Excellent commentary.👊
That was great Matt enjoyed it fantastic explanations and reasons for taking itin order to find what is wrong thank you can't wait for next video.
So this is a great video we learn as we figure it out thank you for sharing looking forward to the next installment six stars
The best channel I`ve ever knew !
You're balls deep now! but I have confidence and some $$ that you'll put it right, good luck and carry on
Made for great viewing as always bro. Safe travels
rossmann repair group in texas .. you can send them the drive and they are very reasonable on prices and very good at what they do
FYI: as you may know, there is water detection paste that you can put on any type of "dip stick" (string, wire,stick, whatever) that changes color in the presence of water. ~$10 at any auto parts store.
I've honestly never tried it... I'll have to give it a try!
A gas station might give you a little bit. They use it to check their tanks for water.
Gasoila Water Finding Paste part # AP02
Cool. I thought I had all the mini vise grips but I e never seen those until now. Cool. Thanks for sharing that.
They are REALLY useful ones! Glad you like them!
7:45 most external hard drives, it's the board that craps out. If you take the drive out and hook it up directly you've got a 75% chance that it's fine
I bought an identical drive and tried that, but no luck... the drive was clicking just before it stopped working, so i'm pretty sure it's something internal! I appreciate the suggestion though!
@@SalvageWorkshop I had the same problem with a HDD. I couldn't mount it to even attempt recovery and it was clicking. On inspection, I discovered the arm was stuck and the part that reads the disk was broken. I searched and searched but couldn't find a solution besides paying a fortune so I had to cut my losses.
@@SalvageWorkshop As was said, there are many reasons as to why a hard drive will not spin up. One trick that I have used twice with success was the freezer one(been around a long time). It will many times give you at least a few minutes of time to get important data off and sometimes can be repeated for additional minutes of "salvage" time. Simply wrap the drive in plastic tightly/put in zip lock eliminating most of the air to help prevent condensation on the drive and place in a freezer for a while. The cold will tighten everything up inside the drive...at least that is the premise. It won't hurt to try it and may work for you as it has for a lot of people.
diesel service sure seems very helpful with so many, sure I will use them when I cross that bridge
You left us hanging!, 😎👌👌
good luck to you. Hope you're successful. I think you'll get it. especially since I think you're putting last years date on the filters
Really enjoyed that buddy 👍🏻🏴
Can hardly wait to see the ending to this problem hope you find it
Good to hear! I did find the issue, but it was a journey!
@@SalvageWorkshop Can hardly wait for the next video
I believe that’s a good machine and it deserves more care!
Me too!
Hi, on the subject of glow plugs I usually just use my cheap multi meter and run a continuity test by one probe on the body and one on the power contact.
You would not believe the number of times so called engineers have told people that the glow plugs are fine when it turned out that all the plugs were open circuit!!
I personally think that you are correct in thinking there are further problems as if it was just glow plugs it would not smoke as much when it had fired and run for a short time.
Looking forward to your next vid on this problem, I am sure you will sort this soon.
I agree that I need to dig into the glow plug circuit, but as you mentioned the smoking while running is the issue I am chasing, not as much the hard starting.
You need to check your glow plugs and see if they are working. Keep the electric fuel pump on after verification of good glow plugs. I think you went wrong direction before getting a definitive diagnosis
Well if my main concern was the hard starting issue, I would have to agree with you, but i am more concerned with the brand new issue of the machine smoking while running, which it has never done before... Plus Ive never used the glow plugs before!
I'm 1/2 way through this video and from you trying to start the skid steer with all the smoke reminded me when I was in the Army. My HMMWV would smoke like this when I tried to start it, I would get my winter file on and hold the exhaust while someone else started the vehicle would create pressure which would help the starting process until maintenance would change out the glow plugs. I believe you have glow plugs issues
Good video, I enjoy the investigation and solving of the puzzle...an idea for the next time you run up against a dirty tank in a lousy place to pull and clean. I am 64, when I was a kid my Grandfather had an old, beat to death Ford pickup he bought for the sole purpose of getting to deer camp. The fuel tank was solid but filthy inside...I mean filthy.
He went ahead and pulled it, and bought a 10 ft or so sewer snake at yard sale, the kind with an interior shaft that turns and the spring housing. He cut the "working end" off of it, and hose clamped two 12ga copper bore brushes to it.
He then slid that thing down the fill neck and proceeded to run it around in the tank while I stood their with his Milwaukee Hole shooter electric drill and spun the other end of the shaft.
A couple of hours with that brush deal, some time blowing compressed air through water like you did, and we had that tank spotless.
He grew up on a farm...didn't have much but he knew how to make things work.
I still have the drill...it' will snap a mans hand off if it gets away from ya.
Awesome,thank you ,I learn everything mechanic diesel, 👍👍👍👍👍
If only we could go back in time, you'd probably rethink that power wash...
eh maybe justa squirt with the garden hose. yeah! looking good
Good job 👍
For your question about the HDD, if it's an older spinning disk hard drive (not a flash/SSD) and it won't spin up or has a problem initializing and you're at your end of options then you can try putting it in the freezer. Seriously. Put it in the freezer for a few hours and if it's a motor/head stuck/crash issue then the cold might break it free and let it work for a little while.
Use at least one or more ziplocks, get as much air out of the bag as possible and freeze it overnight. If it connects and you get data, copy as fast as possible because it's going to fail again and probably soon.
Good luck.
love this diagnos videos tyvm
For data recovery, I'd recommend Rossmann Repair Group out of Austin, TX. Last I checked, he charges a whole lot less than thousands of dollars that other recovery companies want.
If you want to have a go yourself, a common problem on WD external hard drives is that the internal hard drive becomes partially or fully disconnected from the controller board inside the drive. Over hundreds or thousands of thermal cycles, the SATA connector disconnects itself. Problem is actually getting inside those units is a bastard. They're held together with clips and sometimes hidden screws. Getting the case off is usually a destructive affair.
Another common failure is the power supply fails. Most commonly, the capacitors inside the power supply brick/wall wart go bad and the power supply starts putting out dirty DC, which causes havoc with the hard drive controller and the hard drive itself. You can crack the power supply open and fix them, but it's easier and cheaper to just buy a replacement.
I had a mitsubishi engine with the exact same starting problem..In my case everything started with a broken hose, which led to an overheat, then a warped engine head...same starting problem, same smoke, same instability. I recommend you to do cylinder pressure tests and gasket leak tests...Since you pressure washed, maybe the engine was too hot when you did it. Good luck
Good luck
Dang nab it! You got me hooked on ANOTHER freaking vehicle!
LOL... I'm sorry... I think!?! lol Thanks for joining the party!
Thanks!
the thing you said you didn't know what it was, that looks like one of those things that attaches the spout of a plastic fuel can to the can so it doesn't fall off when you unscrew it to refill the can. It probably broke while someone was fueling and fell off into the tank.
Interesting video 👍👍
Wonderful❤
Along with everything else you are doing, I think you should also check the compression.
Agreed, and I'll show you a compression test coming up!
I watched this whole thing and I'm totally invested and now I didn't get to see it fire up
This looks like classic case of bad glow plugs. They might have burned out, or the wiring is bad, or the glow plug timer. The white smoke and difficult starting is classic glow plugs.
awesome!
At work we put a atf in the fuel filters on filter changes with diesel equipment
For those who don't know why one would prefill the filters, it's simple. The engine will start sooner and more easily not having to to get all that air to displace.
Agreed!
It definitely helped that he cleaned the whole fuel system though .
For the external HDD, first try to take the HDD out and plug it straight into an desktop PC.
If it doesnt work, you may try to diagnose the problem if you have multimeter.
Measure the diodes and transistors in the HDD's PCB, ive found out that many times the transistor responsible for powering the spindle motor is bad.
If you find the bad part, you may replace it with a new one, or via component tester, desolder parts from E-waste until you find correct part.
You may by another 4tb western digital hdd of the same type, try it's pcb to your hdd, or measure what the damaged part was so you have point of reference,
And if all else fails, you have new 4tb hdd to use in your external hdd caddy.
Personally, i dont recommed external HDD's, as they are way more prone to external damage.
However external SSD's dont have this problem and are way better for external use than HDD's
Those are all hreat tips! I'd like to add one more: With a mechanical HDD (not an SSD) it may be due to a stuck motor or stepper motor. I've had good luck with freezing broken HDDs. Put it in a plastic ziplock and put it in the freezer for a couple of hours. More often than not this revives the disk just long enough to get the data off. It's worth the try.
You beat me to it.
@ The good ol' freezer trick, was just going to suggest that myself.
Now I know why I like reading the comments on videos. Never heard of the freezer trick👌
Yup first thing to try would be to freeze it in a zip lock bag to try to temporarily revive it (even better if you can run it while in the freezer via a long cable). Next is to remove the hdd from the enclosure and either try a different external hdd adapter or install it normally inside the pc. I dont know about swapping hdd circuit boards, you would have to find one with the exact same model and probably also the same board revision.
15:30 in my country we call those classic pliers “parrots” and the flat long ones “crocodiles”)
not sure if you have done anything with your hard drive issue - you might be able to use something like easeUS to take a sector by sector read of the hard drive (so long as the external drive allows it) if it doesn't you might need to open the external drive and convert it to an internal drive. Once you take a sector by sector backup, you can possibly use that to perform a recovery on via easeUS, or other drive recovery tools that work on disk images.
Is there an Old Red update?
The issue is clearly a glow plug issue.
This is the first place to start to cure starting issue.
The lift pump on the filter is the only way you’ll get fuel to pump out of the filter bleed. Open the bleed and crank and you’ve filled the system with air again and are back to square one.
Awesome , I know it takes a lot of time to narrow down and kill the demons but you will get many hours more of running time and work once she's all done .
I know you already have it solved brother! But I’m just saying while watching the video! lol 😂
I have a suggestion:
Buy a laser pointer so you can highlight what you're seeing, to the viewers. Just a thought.
You're a bad ass at fixing things, don't get me wrong, I just think it could come in handy every now and then.
For your hard drive problem. I’ve had really good success with pulling HD out and putting them in a external docking station that plugs into a usb. Plus if it doesn’t work you can still use it to mount a new HD.
See this one amazon: SABRENT USB 3.0 to SATA External Hard Drive Docking Station for 2.5" or 3.5"' HDD, SSD [Support UASP] (EC-UBLB)
Diesel Creek had a similar issue hard starting smoke. The problem was exhaust gases getting in the fuel/air intake cutting down on the air needed for combustion. DC had a pony motor exhaust in the manifold which was leaking into the air intake. Hope it helps.
You should try to start the dozer at the junkshop that would be fun to watch
TDC can be found by putting a rod down the glow plug on #1 cylinder and manually rotating the crank until the rod comes all the way up and starts back down taking the difference between the 2 on the crank will be TDC
@ Salvage Workshop
At 1:01:03 you are on top dead centre firing on no4 as the valves “on the rock” means that cylinder is transitioning from the exhaust to the induction stroke!
I think there are two separate problems, one of which you may have overcomplicated. The starting problem looks like simply not enough heat. The white smoke indicates fuel, and it runs good after it starts so not sure where you are wanting to go with the injector pump thing. Glow plugs are VERY important, or else they wouldn't be there. Isuzu and several other manufacturers utilize glow plug relay that indeed operate the glow plugs after the engine starts. The second issue with the smoking while operating looks like good old oil burning to me. it's blue, not white or black.
Agreed!
Also, I have had a similar issue with an old external Hard Drive, so i went on line and bought a new external enclosure (one that would normally be a Buy your own Hard drive and install it kinda kit thing) and it worked, it turned out to be the small board in the old enclosure not my Hard Drive. I know i probably got lucky but it only cost me like $40 at the time to try it so..... and as usual, thanks for sharing, i was very curious to see what you would find on this after all that work you did on the last video.
When we have new Kubota's come in for excessive smoke on start even with glow plugs , we do a full set of injectors. Now that being said thats on a new unit...Your skidsteer might be low on compression or the candles are garbage 🤟
When you were showing the bleeding of the fuel lines I couldn't help but notice what looks like a seriously kinked line right at marker 39:37 right next to your thumb and connected to that fuel filter. It looks like a 90 degree bend with a kink that looks like it is almost totally restricted. Could be wrong but maybe worth a look.
Yes. Had to slow down the payback speed to .5 but I see it too.
Yeah I can see that, but it seems to be getting plenty of fuel through it... It looks to me like that bend is factory and not something that accidentally bent it or someone else messing with it!
I worked on a gehl ctl 80 this summer and it’s fuel tank was clogged like this with sludge. I was debating using water or gasoline and the gas dissolved a bunch of that and I flushed it out with kerosene. And started up and ran great.
this is a perfect example of why old equipment fuel caps say to buy clean fuel and keep it clean.
When you showed the fuel line inspection you didn't fix the crinkled copper fuel line that may help getting more fuel. also a small eclectic fuel pump can help out an old system that you have I like your content and work ethic!!!
Thanks Bill, but that fuel line was bent that way from the factory, and plenty of fuel gets through it, so i'm not worried about that...we're going to dive into the pump and shouldn't need to add an electric fuel pump... my goal is to get it to run the way it was designed to.... hopefully I can make that happen!
I wonder if there is glow plugs on this and they aren't working. You are right about the white smoke being unburned fuel from the combustion chamber typically when the engine fires the smoke should be darker.
14:59 Prolly used a tiny little wrench. The vast majority of hose clamps I've used have a dual fitment screw in them; you can either use a ntu driver on a standard external hex(3/8 I think) or hit 'em with a screwdriver. Nothin' stopping a fella from taking a wrench to that hex if they need or want to.
I was watching Hells canyon diesel , he went right through the rebuild of the fuel injection pump .Probably to late ,but just a suggestion .May help you out in the future with your projects ,cheers .
Re: the hard drive - you can get in touch with Rossmann repair group in Texas. The owner - Louis Rossman has a youtube channel as well
Cliffhanger we’ll I guess I’ll have to wait for the next video
Good video. I can't help wondering if the pressure wash either took out or affected the glo plug circuit so the plugs are either not working or not getting up to full temp. Also I would check that the injector pump electric shut off valve is getting full power to open it.
I just saved an old WD 1TB portable hard drive and and was the connection between the board and drive that failed did a little soldering it works now. Also have an old gehl 4625sx with similar issues.
Small world i should have video both the rewiring of the skid steer and the and of the Hard drive but oh well
Get a "snake" or a "Snake Drain Cleaning Hose" extension for your pressure washer. Great for blocked drains but should work for situations like your tank cleaning..
Good.job😄👍👍👏👏👏cool
My diesel Land rover I had used to smoke white because of a pinhole in the fuel line sucking in air I fixed it once I found the slight leak and it was great after
If you buy an identical hard drive, it may be possible to swap over the controller boards. That would resolve an issue with the controller but NOT with the hard drive itself. Find a tool that analyses the SMART data and determine the error type. It may give you an idea as to whether the damage means that it is unrecoverable in a financial sense. Try connecting the drive to different PCs and see if any of them can view the contents. Ultimately the data can be recovered but it will cost you, they have expertise and tools beyond most of us.
You can take apart the external hard drive and remove the drive to insure that it's not one of the boards in between the drive and your PC
