i was a crewman on an m60a3. those old piston engines sound way different than the diesel turbine engine that powered the one i was on. my tank was 2 years older than me when i was on it. it was born in a chrysler plant in '63, and i was in indiana in '65. i loved the old girl. every time i smell diesel exhaust i still think of her, and feel all warm and fuzzy inside. i can only hope someone is out there taking as good care of her, as you did this one. thanks.
Scott, as an Army veteran with 26 years of service to our country, I declare you Heavy Track Mechanic certified!! HOOAH to ya!!!God bless you and the USA. Thanks for what you do. 💪🏾
I know the K60 very well. Worked as a Tank Mechanic from 1988-2011 It was still in use with the British Army in 2011 when I left. The roots blower is not a "performance" orientated feature. It's used as a "scavenge" blower, the boost pressure is used to blow the exhaust fumes out of the combustion chamber/cylinder. When the drive shaft for the blower snaps, the engine will turn over fire on all 6 cylinders then nothing. It's "multi-fuel" capable and pretty reliable.
Jambo You are being far to literal, a pretty standard joke about military vehicles and Detroit Diesels is if they aren’t leaking you need to fill them up with oil because they must empty.
Those paired 6-71s remind me of the Aluminum LCM-8, which had them paired up at each propeller, and the rust buildup on the new cast iron engines. I had to run one of the two mike 8’s we had, all night long in the small harbor, because of a tidal surge which came at Johnston Island, in a storm. Another coxswain ran the other 8, and both were saved unscathed.
Those Detroits are so reliable and versatile that I think that if ever an alien ship is caught, maybe we'll find out that it is equipped with a series 71 or 92...!
Theyre reliable engines so long as they have oil. I had a buddy with a 4V53 tractor, I believe the engine was swapped into it, and that thing ALWAYS leaked. So whenever we had to go use it we always looked under it and if there was a puddle we knew she was good to go. Just top her off a bit and your good as gold. I love those old Detroits, even if they poluted like nobodys buisiness
FairBanks Morse are still making 2-stroke opposed piston engines for big generators. They are multifuel engines. I guess you can find them in some country's where the fuel situation are different. The opposed piston idea is interesting, but couldn't reach the emission requirement. Commer trucks had a 3 cylinder (6 piston) in some of the trucks models.
Scott your so lucky, your living my dream job. When you get back to indy give me a ring, i found some 8v71 parts that look like there still usable in one of your future Detroit Diesel service jobs. The shop i work at hasn't had a 2 stroke Detroit come threw it in over 30 years. My boss said to just toss them in the scrap bin but there still very servicable, so i figured instead of scraping them i would pass them on to you for you to find a good home for them on your future journeys.
About opposed piston engines. As mentioned below, the Napier Deltic is the most awesome and crazy idea that only the British can have made up. Search it on internet, look at the design and think about all the expansion in all directions the is going to appear when it is hot. However It did work for many years in train and in marine applications.
talk about living a young boy's dream ,,did you ever think that you would ever be working on a Tank ,?? wow ,,talent will get you places you never dreamed about ,,and you have the talent
Please gib Sherman it is my dream vehicle. I would use it for reenactments where it would still get used and taken care of. Makes me sad thinking I may never be able to own one of these mighty vehicles. I'd like to keep the history alive. :(
That Rolls-Royce K60 diesel is still a very interesting Opposed-piston engine. The Swedish The Stridsvagn 103 (Strv 103), also known as the S-Tank and The Bandkanon 1, abbreviation bkan 1 (meaning "tracked cannon 1") A 155 mm self-propelled howitzer used thoes enigens!
Ronsons! The French countryside was littered with them for many years after the war. With reliable power plants and drivetrains they were able to outrun and eventually overwhelm the far superior German guns. Early in the war they took quite a beating until the Army was pressured to reinforce the armor plate. But they would always remain vulnerable Not easy to quickly build and then transport tanks across an ocean so this likely influenced the light and fast design. Less than half the weight of the German tanks. What fun to experience working on one.
The Junkers Jumo is the predecessor to most opposed piston engines, the Deltic is an evolution of that design, Fairbanks Morse used this configuration as well, Achates Power are working on a OP Engine using modern engineering techniques for applications in the future.
This friend I knew in HS back in the 70's told me about his Father's service in WWII. Iit was his job to drive a jeep with another man up behind the German tanks. At which point they would fire a bazooka into the backside of the tank (?). This must have been in France or Belgium. Terrible war. Thanks for the film tonight BGM.
The Rolls Royce opposed engine is the same type of engine as a Fairbanks Morse. We had a 10 cyl (20 total) as a generator engine on one of the RCN ships i sailed on back in the 70's.
British brand Commer used the same principle in a truck motor called the TS3. 3 Cyl, 6 pistons, 2 cycles.. They were nicknamed "the knocker". Likewise Leyland built the L 60. 19 litres, 6 cylinders and a glorious noise, it was mainly used to power Chieftan and Vickers tanks.
BGM thanks for the content and description of the equipment at the location your at. FWIW while I was in USN on patrol gunboat in Vietnam saw Napier Deltics out of PTF Nasties that were being operated by the So Vietamese Navy Special Forces. The engines were lined up with obvious various mechanical maladies (holes in gear cases and blocks) on pier that I was told by USN personel had been sabotaged so as not be available for missions. Sad ending to an amazing engine. After my time on PG I was assigned to ACU1 in Coronado Island where I got to be around PTFs that were based there. Nothing like the turbine like exhaust note of the 2 12" dia transom mounted exhaust and watching the boats blaze thru San Diego Harbor at 50 mph with twin 3khp Screamin demon 18cyl 36piston geared centrifucal supercharged diesels. There's a few videos on YT about Brown Water Navy in Nam where you can hear em run but not like in real life IMHO. YMMV.
Manufacturers are trying to revive the Rolls opposed piston design now. The US Military is testing one that Cummins has built and installed in APC units . It’s very compact for its displacement.
Apparently cummins has released an opposed piston diesel recently called the ACE (advanced combat engine)for military applications I can't remember the exact details on how many cylinders I think it's 3 cylinder so technically a 6 cylinder , they are a 2stroke diesel producing around 1000 horse power very interesting none the less. In Australia we used to have British Commer trucks with an opposed diesel called a knocker, (commer knocker) built by the Roots Group , they made around 110 horse power and I think they were a 2 stroke diesel as well from memory .
My Dad drove one during the war. He told me that they were a bi##h to start when cold, so one driver in the platoon would stay up at night and run the engines periodically to keep them warm, then in the morning that tank would drag the other tanks to bump start them. He also said he slept on top of the transmission because it stayed warm most of the night.
I never knew that there was a twin diesel version of the Sherman tank. I always was under the impression that it only came with that radial engine... Cool! Learned something new, today, with The Bus Grease Monkey!
There was also the 8 cylinder (Chrylser produced) Ford _GAA_ vee pattern engine, the Caterpillar _D200A_ diesel radial engine (didn't see combat service), Chrylser A57 multibank (essentially five 6 cylinder inlines from a car strapped around a common driveshaft), and the GM Detroit Diesel Model _6046_ twinbank with two 6 cylinder inline Diesel engines you see here.
Detroit Diesel made a 4 engine arrangement with 4 6-71s. They were mostly used in marine applications. The navy had a bunch of them in the 40’s the Quads and twins went away after the bigger V type engines came out. The other oddity I like is the old 6-110 engines. There were a lot of those in a lay down version (pancake) used on Diesel rail cars and marine Then there was the 149 series. 8, 12, & 16 V type 149 cu. in per cylinder. They were used mostly in mining equipment and for generators.
Look up Achates diesel. A relatively new company who is developing modern opposed piston, multi fuel engines, and is working with Ford. They have some test trucks out on the road. Expected combined fuel economy in a 1/2 ton pickup is about 42mpg.
That rolls k60 was based on a Leyland engine, my dad worked on them in chieftain tanks in the 60's Apparently they burned so much oil you could see the smoke before you heard the tank. Tilling Stephens "commer ts" is probably the most unusual and successful British opposed piston diesel, they managed to build it with just one crank... Top marks to whoever figures it out first!
There was a TS 4 planned that was supposed to be even better . But Chrysler killed it due to impending noise/pollution laws on the horizion. Many said the TS4 was even more refined and what the TS3 should of been all along. There is a running TS4 prototype that ended up in Australia 🇦🇺
Now you have to have a meme w/ and US Army cap... I welcome you as I was Army, our mechanic's were called Grease Monkey's... From the MOTORPOOL.. from those days..... . ... Scott, you could have been a Sherman Mechanic back when... congrats...
The most famous opposed diesel engine is the Fairbanks Morse engine used in US submarines before the nuclear era. I've read comments saying it was the greatest submarine power plant ever designed.
Ok, so my 4107 has the 8V71, what would you think it might cost to swap to two 6V71's and if a enough change left over, add a turret and 76MM gun? Ya got that magic touch going on here!
They were referring to the Ford GAA, a largely Chrysler produced engine (don't ask, that's U.S. War Department contracting for you). Chrysler was and is based in Detroit.
Funniest thing is they had Governors on them to keep from running away. If you bumped the Gov off for a short time you could have probably gotten those Shermans to go another 3 to 5mph. Those Detroits are great engines, just not exactly the best for combat cause theyre great engines, just not under fire and the constant beating of being in a tank. I love the sound of em and my dad at the very start of his Diesel mechanic career saw a very few bit of em. He said these exact words to me "theyre heavy, theyre noisy, theyre leaky and theyre only good for turnin fuel into noise. Other than that theyre pretty much useless" I still love em just for how noisy they are
jimo199966 The diesel engined versions were used for swimming tanks, i.e. for D-Day in Normandy, reportedly because the petrol engined versions reacted badly to the cold ocean water. N.B. The REME mechanics were not particularly fond of the Yank tanks that were equipped with aero engines because they had their carburettors on the bottom and were prone to catching on fire when starting. They also had a habit of blowing up if you swapped them around. One day, whilst on a short detachment to Waiouru, in 1993, I was visiting the QEII Army Museum and got talking with an upright gentleman who was probably in his 80s. He was CREME (Commander Royal Electrical and Mechanical Engineers) for the 2nd NZ Division. He was extremely proud of the men who served under him and what they had done to keep the division’s vehicles running. He told me that on the last hundred miles to Tobruk, the division’s trucks burned more oil then diesel. There was a huge black cloud on the horizon! In regard to tanks, there was a commander who kept racing ahead of his troops, so they put a slower engine in his tank (presumably on General Freyburg’s orders) but he complained and insisted that they sort out his tank and make it fast again. They blew up two engines in the process of all that work. It was a great privilege to meet and talk with that gentleman. He must have been an outstanding leader to his men, in extremely challenging conditions.
Thank you for that information Michael. I envy you for having had the opportunity to speak with the CREME who served with distinction and honor in WWII. I'm no authority on armor but you certainly spoke with one! I'll definitely crack the books and see what else I can learn. Cheers and thank you for your service👍

I’ve read articles they are looking into bringing that first engine back into production but for cars...I didn’t realize that technology has been around for a long time
Sounds like it has a hell of a lumpy stick in it on cold start. Very cool. Its really gotta be a nice and interesting change of pace to turn wrenches on this thing.... Looks really sweet I mean come on, it's a tank for christ's sake lol
These Tandam 671 were also used in small harbor tugs and a few ferry boats,, 1960 and 70s,, Dont forget After WW2 there were so many surplus 671s left over from ww2 that went to good use in lobster boats, fishing boats, ferry boats and yachts,, Too Bad the EPA croaked them !!!
@@newjerseybill3521 Yes a Few Coast Guard light ships had the quads, Navy Landing craft tandems LCUS, and even a canaidian tug boat. Also in boston they had a Pilot boat with 2 12v71s back to back albiet not a quaud !
@@newjerseybill3521 Think Detoit diesel tryed bolting 2 12v71s togethe5 to make a 24 -71 sort to speak,, only saw one in and old pilot boat 1970s version,, it was hard to keep them running and adjusted as they had there own governers,, kinda of a rare bird,, Howver they had better luck with 2 8v71s bolted togrther in later years The 16 71 Many were used in a marine applications
@@edmctug8800 Oh, that kind of back to back. There was a 24V71 gen set on ebay a short while ago. We had 3 pairs of 16V71,s on M&T Harbormasters. They where basicaly IO,s on steroids, that turned a full 360 degrees, to give steering and ahead / astern.
Somehow I just don’t think that twin 671 would have enough beans to get that Sherman out of trouble…🤔…that being said they were extremely tough and reliable engines..
Scott: if you like the opposed piston diesel idea, the Germans have actually put opposed diesels in planes. Junkers Jumo 20x series. Would be some good leisure time reading for you~
@Rick Delair I love your comments on many of the opposed piston comments. I found Achates a while ago & thought I'd love to get my hands on one of the Junkers (sp?) engines when I stumbled across one in an airplane museum in Ottawa. -been fascinated ever since. I think Achates will do great, but personally I'd like an old school engine without all the extra crap they put on them now. I've got I think 6 or 7 Detroit engines 53's & 71's I guess also a 692 as well. -Actually the photo on my profile is a 59 Chevy I put an Aluminum block 353 in more than 25 years ago.
@Rick Delair I've never heard of them. Will have to do a little research. Do you know of any good videos of them? Did you make any yourself? One problem is having too much stuff. I've got lots of different projects in various stages of development or ideas,. but being a normal working guy with space and farmboy experience, I'll likely never get them all done and it will all be sold for scrap after I die. What interests me most (at least on and off over the decades) is the idea of building or finding a vehicle that's excellent on fuel, simple in mechanical engineering and capable of driving a million miles instead of the disposable over engineered overpriced junk they're producing now days.
I was under the impression Sherman tanks had a gas motor. They were called The Ronson by the Germans because they burned very easily with all that gas. So I guess my question is this a later model than the ones used in WWll or was I just wrong?
Three things - 1. The many of the Diesel-Electric submarines of WWII used a Fairbanks-Morse 2 cycle with 2 opposed pistons. Also used as supplemental power in some nuclear subs and other ships. They were also used in some railroad applications and stationary applications (electric generation and such). F-M produced several railroad engines such as the FH-H-24-66 Trainmaster and FM-H-16-66 Baby Trainmaster with the opposed piston engine. No valves. Two sets of ports in the liner. One at the top and one at the bottom. Just a blower to push air at the bottom and exhaust at the top. They had a vertical shaft with bevel gears that connected the 2 crankshafts. The cylinder height is 38 inches and the bore is 8 1/4 inches. Wiki says the engine is still in production. en.wikipedia.org/wiki/Fairbanks_Morse_38_8-1/8_diesel_engine 2. The Napier-Deltics were weird. They were British. They had all sorts of problems because they were so complex. They had 3 crankshafts. One on the top left. One on the top right and one in the middle of the bottom. If there were 6 sets of 3 cylinders there would be 36 pistons. You can immediately see the problems that developed. Piston wear, gear wear, keeping the horizontal top cylinders lubricated, keeping the downward cylinders from draining oil into the combustion chamber, etc Check UA-cam and search for Napier-Deltic. Lots of noise. Cantankerous creatures. At Wiki there is a great gif of the cylinder motion and a bizarre picture of the firing order. en.wikipedia.org/wiki/Napier_Deltic 3. Checkout the Junkers Jumo 223. Maybe used in one German Junkers 52 aircraft. A Diesel aircraft engine! Called a diamond shape. 4 crankshafts. 2-cycle. Think of this bizarre number -- At 24 cylinders, 48 pistons and the cranks spinning at 4400 rpm would be 105,600 ignitions per minute!!! talk about smooooooth power! One HUGE gear in the middle controlling timing. Google Junkers Jumo 223.
That’s a different kind of warfare from the games we learn as kids. Can’t sneak up close with a smoke belching ear splitting beast like that but then if we’d had water pistols with guns like that we wouldn’t need to.
Hey Scott, did you see the picture of one of the liners in the overhaul manual for the 6046? The ports on it are so tiny it makes you wonder how it even was able to make any decent power.
i was a crewman on an m60a3. those old piston engines sound way different than the diesel turbine engine that powered the one i was on. my tank was 2 years older than me when i was on it. it was born in a chrysler plant in '63, and i was in indiana in '65. i loved the old girl. every time i smell diesel exhaust i still think of her, and feel all warm and fuzzy inside. i can only hope someone is out there taking as good care of her, as you did this one. thanks.

Power washing the motor, that’s what I’m talking about . A clean motor is a happy motor 👍
Then Detroit needs prozac
Jambo You are being far to literal, a pretty standard joke about military vehicles and Detroit Diesels is if they aren’t leaking you need to fill them up with oil because they must empty.
@Jambo yep if it's not leaking check the dipstick!:)
@Jambo that also applies to land Rover but a bunch of British vehicles as well
I love the sound of a synchronized pair of Detroits, especially in a boat. Setting the governor up right and a free rack makes a big difference.
The last report from a few days ago the Sherman is running perfectly
Bus mechanic, truck mechanic, heavy equipment mechanic, yacht mechanic and tank mechanic. Great career!
Buena Ventura Life I would like to be all those in addition to a motorsport driver
American engineering!!! What a great opportunity for you Scott. Thanks for sharing this experience with us.
whew...the sound of that ol' girl is incredible!!! Music to my ears.....
Tampa Florida check in love your channel doing things besides busses but I do love your bus’s videos very interesting

Runs like a champ I'll tell ya that. Really impressive to see that thing alive and well.
And the sound of those two engines running is mind blowing
The Deltics were also used in Vietnam era PT boats. Kind of a temperamental engine though, required precise maintenance.

5:34 ~ 5: 38 I am always amazed when these Detroits just suddenly smooth out completely, all of a sudden.
I guess you should start looking for a Sherman with twin DD 671s and a blade in front to use on the Tennessee property in place of a dozer.
The Napier Delta was used in Navy PT boats in service during the late 60's early 70's as well. Saw one at Great Lakes Naval Station in 73.
Sounds a million times better without that balancer thing banging around. Great video and good job fixing her up.

Great job Scott. you can fix anything!!
@1:34 A FV433 Abbot is definitely NOT a tank as stated, it is simply a self propelled gun. Tracks + gun do not necessarily make a "tank".
SPG's and tanks are not the same thing for certain. Especially in the armor dept. But devastating nontheless.
This is such a cool thing.. I love how your channel is growing and you're working on very impressive stuff like this.. Keep it up Scott! 👍👏

Fairbanks Morse made OP diesels popular in ships and submarines. They built diesel electric train engines for a while too.

Not really the case with most German tanks.

Dude...You're working on a Sherman Tank!!!!
The Napier Deltic was also used in a Vietnam era PT Boat. They were called the "Nasty" class boats and had a pair of them each.
The FDNY Super Pumper used a Deltic.
Nice to see those clean and shining valve cover 's

Did you fix the loose crankshaft dampener yet?
It's a damper.
Fairbanks-Morse made a bunch of opposed piston stuff for submarines.
Fore sure, A lot of the Fairbanks Morse 8 and 10 cylinder Ops were used in post war Harbor tugs
alm3333 Also RR switch engines
My Dad drove one during the war. He told me that they were a bi##h to start when cold, so one driver in the platoon would stay up at night and run the engines periodically to keep them warm, then in the morning that tank would drag the other tanks to bump start them. He also said he slept on top of the transmission because it stayed warm most of the night.
Achates Power is making a 3-cylinder opposed-piston 2-stroke diesel. I may be remembering incorrectly, bit I seem to recall they're working with Ford
I never knew that there was a twin diesel version of the Sherman tank. I always was under the impression that it only came with that radial engine... Cool! Learned something new, today, with The Bus Grease Monkey!
There was also the 8 cylinder (Chrylser produced) Ford _GAA_ vee pattern engine, the Caterpillar _D200A_ diesel radial engine (didn't see combat service), Chrylser A57 multibank (essentially five 6 cylinder inlines from a car strapped around a common driveshaft), and the GM Detroit Diesel Model _6046_ twinbank with two 6 cylinder inline Diesel engines you see here.
Nathan Peterson don't forget the R-975 radial engine.
The Chrysler multibank was weird but it was super reliable.
Detroit Diesel made a 4 engine arrangement with 4 6-71s. They were mostly used in marine applications. The navy had a bunch of them in the 40’s the Quads and twins went away after the bigger V type engines came out.
The other oddity I like is the old 6-110 engines. There were a lot of those in a lay down version (pancake) used on Diesel rail cars and marine
Then there was the 149 series. 8, 12, & 16 V type 149 cu. in per cylinder. They were used mostly in mining equipment and for generators.
Bill Moran Allis Chalmers used the 149 in crawler tractors
Fairbanks Morse submarine engines were 18 cylinder opposed piston engines as well
Wonder how many grease fittings are on that thing.
Look up Achates diesel. A relatively new company who is developing modern opposed piston, multi fuel engines, and is working with Ford. They have some test trucks out on the road. Expected combined fuel economy in a 1/2 ton pickup is about 42mpg.
Perfection in sincronized the engines, tuned as an musical instrument!
That rolls k60 was based on a Leyland engine, my dad worked on them in chieftain tanks in the 60's
Apparently they burned so much oil you could see the smoke before you heard the tank.
Tilling Stephens "commer ts" is probably the most unusual and successful British opposed piston diesel, they managed to build it with just one crank... Top marks to whoever figures it out first!
There was a TS 4 planned that was supposed to be even better . But Chrysler killed it due to impending noise/pollution laws on the horizion. Many said the TS4 was even more refined and what the TS3 should of been all along. There is a running TS4 prototype that ended up in Australia 🇦🇺
I wonder if these folks had been to the Jacque Littlefield collection in Calif? It's gone now.
TheClampettmobile the majority is now at Hudson in MA as the American Heritage Museum
Looks like those track rubbers are about gone. Probably can’t get replacements off of amazon either.
Now you have to have a meme w/ and US Army cap... I welcome you as I was Army, our mechanic's were called Grease Monkey's... From the MOTORPOOL.. from those days..... . ... Scott, you could have been a Sherman Mechanic back when... congrats...
Did the harmonic balancer issue get resolved, or is that a to-do ?
touching on the deltics, there's a group restoring one to service. it's called the baby deltic project and some of their stuff is on youtube here
That ceiling fan in the other room is huge! How do they get them both to have the exhaust against each other are the heads just turned 180°?
First round is on the house! ....and everything within fifty yards!!!
LOL
So you fixed the dampener? You didn't show that...
Yeah, what happened with that??
Ya what about the damper
The noise disappeared.
He said in another comment that he jerry-rigged a fix. Basically good enough until they can take the engine out and do it properly.
The most famous opposed diesel engine is the Fairbanks Morse engine used in US submarines before the nuclear era. I've read comments saying it was the greatest submarine power plant ever designed.
Runs like a clock now great job 👍🇦🇺
The whole family gathered in the living room tonight for day 2 “‘dad, turn it down, the whole house is shaking”
.. i was conflicted turn up the sub-woofer or down because i can hear the pictures rattling on the walls...
Test d around the track
I wonder how long it will take you🤔👍👍😍😍
Ok, so my 4107 has the 8V71, what would you think it might cost to swap to two 6V71's and if a enough change left over, add a turret and 76MM gun? Ya got that magic touch going on here!
They will hear our Detroit motors
long before we even get inside that town. - Oddball
They were referring to the Ford GAA, a largely Chrysler produced engine (don't ask, that's U.S. War Department contracting for you). Chrysler was and is based in Detroit.
@@peterson7082 Stop it with those negative waves, man. (Chrysler A57 would have been in those Yugoslavian Shermans, I think.)
@@peterson7082 I can't find any info on Chrysler making the GAA?
Donald Sutherland said that in what movie?
BILL S what movie was that in ? They also delivered a baby inside the tank and used rubbers for gloves.
Those dual Detroit's sound so good.
Funniest thing is they had Governors on them to keep from running away. If you bumped the Gov off for a short time you could have probably gotten those Shermans to go another 3 to 5mph. Those Detroits are great engines, just not exactly the best for combat cause theyre great engines, just not under fire and the constant beating of being in a tank. I love the sound of em and my dad at the very start of his Diesel mechanic career saw a very few bit of em. He said these exact words to me "theyre heavy, theyre noisy, theyre leaky and theyre only good for turnin fuel into noise. Other than that theyre pretty much useless" I still love em just for how noisy they are
Scott, look for the Deltic locomotive on UA-cam; for a regular opposed piston look for Fairbanks Morse locomotives....
FM's were in WW2 subs too. I think some Navy ships used them for main and auxiliary electricity generation.
I didn't hear the harmonic balancer clanking today did you find a fix for it or replace it Scott????....Thanks...Jack Baker
Fairbanks Morris still makes opposed piston diesels...
Is this a retro fit engine I was under the impression that Shermans were all gasoline?
Scott mentioned yesterday that the Army specs were gasoline engines and the Marines wanted diesel.
jimo199966 The diesel engined versions were used for swimming tanks, i.e. for D-Day in Normandy, reportedly because the petrol engined versions reacted badly to the cold ocean water. N.B. The REME mechanics were not particularly fond of the Yank tanks that were equipped with aero engines because they had their carburettors on the bottom and were prone to catching on fire when starting. They also had a habit of blowing up if you swapped them around.
One day, whilst on a short detachment to Waiouru, in 1993, I was visiting the QEII Army Museum and got talking with an upright gentleman who was probably in his 80s. He was CREME (Commander Royal Electrical and Mechanical Engineers) for the 2nd NZ Division. He was extremely proud of the men who served under him and what they had done to keep the division’s vehicles running. He told me that on the last hundred miles to Tobruk, the division’s trucks burned more oil then diesel. There was a huge black cloud on the horizon!
In regard to tanks, there was a commander who kept racing ahead of his troops, so they put a slower engine in his tank (presumably on General Freyburg’s orders) but he complained and insisted that they sort out his tank and make it fast again. They blew up two engines in the process of all that work.
It was a great privilege to meet and talk with that gentleman. He must have been an outstanding leader to his men, in extremely challenging conditions.
Thank you for that information Michael. I envy you for having had the opportunity to speak with the CREME who served with distinction and honor in WWII. I'm no authority on armor but you certainly spoke with one! I'll definitely crack the books and see what else I can learn. Cheers and thank you for your service👍
There was also the 8 cylinder (Chrylser produced) Ford _GAA_ vee pattern engine, the Caterpillar _D200A_ diesel radial engine (didn't see combat service), Chrylser A57 multibank (essentially five 6 cylinder inlines from a car strapped around a common driveshaft), and the GM Detroit Diesel Model _6046_ twinbank with two 6 cylinder inline Diesel engines you see here.
@@michaelguerin56 Not the case. Most of those that landed were actually _M4A1's_ or _M4A4's_ (the latter only for the British and Commonwealth).
I’ve read articles they are looking into bringing that first engine back into production but for cars...I didn’t realize that technology has been around for a long time
The headset is a great idea for communication!
Boy, Scott can sure make those diesels purr 😸
Now, can you make the power washer stop ‘hunting’?
For 2 cyl opposed look at Fairbanks Morse 38 in WW2 subs. Design is still in use.
what did you do to fix that crank ring? that was making noise
Prob'ly just wedged a washer in there.

I thought it was interesting Scott has to bar over the engine access doors.
Sounds like it has a hell of a lumpy stick in it on cold start. Very cool. Its really gotta be a nice and interesting change of pace to turn wrenches on this thing.... Looks really sweet I mean come on, it's a tank for christ's sake lol
These Tandam 671 were also used in small harbor tugs and a few ferry boats,, 1960 and 70s,, Dont forget After WW2 there were so many surplus 671s left over from ww2 that went to good use in lobster boats, fishing boats, ferry boats and yachts,, Too Bad the EPA croaked them !!!
In addition to the tandems, they also made twins, and quads. Really neet machines!!
@@newjerseybill3521 Yes a Few Coast Guard light ships had the quads, Navy Landing craft tandems LCUS, and even a canaidian tug boat. Also in boston they had a Pilot boat with 2 12v71s back to back albiet not a quaud !
@@edmctug8800 Wonder if they called the 12V71,s back to back "Twins" like the old 6-71s back to back "twins".
@@newjerseybill3521 Think Detoit diesel tryed bolting 2 12v71s togethe5 to make a 24 -71 sort to speak,, only saw one in and old pilot boat 1970s version,, it was hard to keep them running and adjusted as they had there own governers,, kinda of a rare bird,, Howver they had better luck with 2 8v71s bolted togrther in later years The 16 71 Many were used in a marine applications
@@edmctug8800 Oh, that kind of back to back. There was a 24V71 gen set on ebay a short while ago. We had 3 pairs of 16V71,s on M&T Harbormasters. They where basicaly IO,s on steroids, that turned a full 360 degrees, to give steering and ahead / astern.
all i can type is TANK YOU!
Did you already fix the flywheel dampener overnight?
The twin Detroits appear to be much less complicated than the radial and Ford engine used in other types of Shermans.
and the 5 banq chrysler flat head
Somehow I just don’t think that twin 671 would have enough beans to get that Sherman out of trouble…🤔…that being said they were extremely tough and reliable engines..
Scott: if you like the opposed piston diesel idea, the Germans have actually put opposed diesels in planes. Junkers Jumo 20x series. Would be some good leisure time reading for you~
@Rick Delair I love your comments on many of the opposed piston comments. I found Achates a while ago & thought I'd love to get my hands on one of the Junkers (sp?) engines when I stumbled across one in an airplane museum in Ottawa. -been fascinated ever since. I think Achates will do great, but personally I'd like an old school engine without all the extra crap they put on them now. I've got I think 6 or 7 Detroit engines 53's & 71's I guess also a 692 as well. -Actually the photo on my profile is a 59 Chevy I put an Aluminum block 353 in more than 25 years ago.
@Rick Delair I've never heard of them. Will have to do a little research. Do you know of any good videos of them? Did you make any yourself?
One problem is having too much stuff. I've got lots of different projects in various stages of development or ideas,. but being a normal working guy with space and farmboy experience, I'll likely never get them all done and it will all be sold for scrap after I die.
What interests me most (at least on and off over the decades) is the idea of building or finding a vehicle that's excellent on fuel, simple in mechanical engineering and capable of driving a million miles instead of the disposable over engineered overpriced junk they're producing now days.
Did I miss something? I didn`t hear the harmonic balancer/vibration dampner. Did you fix it already or something? I`m lost. :(
Man thats one hell of a starter
Scott did you see my message about the bus for sale in Manning, SC?
I was under the impression Sherman tanks had a gas motor. They were called The Ronson by the Germans because they burned very easily with all that gas. So I guess my question is this a later model than the ones used in WWll or was I just wrong?
They had multiple power configurations.
That is a day you will never forget!!!
Three things - 1. The many of the Diesel-Electric submarines of WWII used a Fairbanks-Morse 2 cycle with 2 opposed pistons. Also used as supplemental power in some nuclear subs and other ships. They were also used in some railroad applications and stationary applications (electric generation and such). F-M produced several railroad engines such as the FH-H-24-66 Trainmaster and FM-H-16-66 Baby Trainmaster with the opposed piston engine. No valves. Two sets of ports in the liner. One at the top and one at the bottom. Just a blower to push air at the bottom and exhaust at the top. They had a vertical shaft with bevel gears that connected the 2 crankshafts. The cylinder height is 38 inches and the bore is 8 1/4 inches. Wiki says the engine is still in production. en.wikipedia.org/wiki/Fairbanks_Morse_38_8-1/8_diesel_engine
2. The Napier-Deltics were weird. They were British. They had all sorts of problems because they were so complex. They had 3 crankshafts. One on the top left. One on the top right and one in the middle of the bottom. If there were 6 sets of 3 cylinders there would be 36 pistons. You can immediately see the problems that developed. Piston wear, gear wear, keeping the horizontal top cylinders lubricated, keeping the downward cylinders from draining oil into the combustion chamber, etc Check UA-cam and search for Napier-Deltic. Lots of noise. Cantankerous creatures. At Wiki there is a great gif of the cylinder motion and a bizarre picture of the firing order. en.wikipedia.org/wiki/Napier_Deltic
3. Checkout the Junkers Jumo 223. Maybe used in one German Junkers 52 aircraft. A Diesel aircraft engine! Called a diamond shape. 4 crankshafts. 2-cycle. Think of this bizarre number -- At 24 cylinders, 48 pistons and the cranks spinning at 4400 rpm would be 105,600 ignitions per minute!!! talk about smooooooth power! One HUGE gear in the middle controlling timing. Google Junkers Jumo 223.
Q: what’s a fellow Do with a Sherman Tank?
A: any damn thing he wants!
Really digging the song, Scott.
That’s a different kind of warfare from the games we learn as kids. Can’t sneak up close with a smoke belching ear splitting beast like that but then if we’d had water pistols with guns like that we wouldn’t need to.
Has someone tried to cram a 6046 into a semi cause id be awsome
Was it a real bear to change the dampener on the starboard engine?
Scott in vocational school w/ GI Joe Hotel...... frickin awesome..... with guns...... and AMMO....!!!!
Hey Scott, did you see the picture of one of the liners in the overhaul manual for the 6046? The ports on it are so tiny it makes you wonder how it even was able to make any decent power.
