Greetings from Russia. You will need to center the engine with the gearbox. You can't just remove the engine and reinstall it. The plate that secures the gearbox to the tank hull is very important. It is fixed with precision bolts, which should not have a gap. This plate is unique for each tank. Be careful with the fan, do not damage it.

The knackered bits at the back are the oil scroll assembly, a sort of non contact oil seal. Most vintage engines had a similar setup. The inner collar has a coarse thread that winds the oil back in to the sump, and should run about five thou clearance. I think that boat's sailed. The weird plate is an oil flinger that keeps the oil away from the scroll. The broken housing controls the crank end float.
The projected time for the engine was about 1500 hours. They lasted 150 hours but in the real world it was closer to 30 hours. Engines made after were far better
And the specific failure isn't surprising as well because the pressure curve of the cycle is very steep while the compound crankshaft isn't balanced well.

Your detailed evaluation of the engine and its components during teardown provides us with an excellent example of "automotive archaeology."

Add to that the stresses associated with combat and primitive maintenance facilities. The Russians simply had to make do with what they had available to them. Well done, sir!
Joe, Continue to thoroughly enjoy each episode you release especially your explanations of what you are doing. Also, nice to see progress thought each of your individual projects. I may have missed an earlier presentation but it would be nice to know the others that help you out and how they fit into the team. Great you have sourced another engine for the T34. Peter
WOW!!!!! What a great video!!! Never in my wildest dream did I think I’d be walked through the tear down of a WWII T-34 engine which surprisingly suffered a self inflicted catastrophic event that exhibited only minor symptoms!!! My dad is a WWII vet (Marine, pacific theatre). He said most of the military equipment was designed around a projected lifespan of survival expectancy, i .e. quantity vs. quality was generally the design criteria. The equipment just wasn’t designed to last past its expected use. I don’t know what the expected lifespan of a T-34 tanker is, but I’d bet the T-34 and the Soviet operator had a lot in common on the survivability spreadsheet.
@@TestECull Wow! My dad was a B.A.R. operator (Browning Automatic Rifle). He said he was taught to fire short bursts and to never stand (or lay) in the same spot after pulling the trigger to avoid the concentrated fire being returned to neutralize his position. He said he was told prior to his first landing that his life expectancy was under 60 seconds. Hence my dad was notorious for telling us kids that there was only 60 seconds in a minute and we were expected to make each of them count! Also, if you weren’t moving at 60 paces a minute you weren’t moving fast enough! LOL
@@MrSeeuu Stalin's steategy, especially early in Operation Barbarossa, was to *quite literally* clog Tiger tracks with bodies until the Germans had no choice but to turn back. Losses meant nothing to him. A T34 that survived 25 hours of combat was a hero tank and it's a large part of why there are so few 76mm and Zis-S-53 armed T-34s left in the world. They all got blowed up.
@@TestECull Thank you so much for the history lesson. That data just boggles my mind. Trying to comprehend the mindset it took to not see the reality of their situation and continue to move forward under overwhelming statistics of doom is unimaginable. Being 16 years old or so and looking down the barrel of finality, I suspect hope for survival becomes your only attainable strategy. How tragic.
@@MrSeeuu It wasnt a hard choice to make. They either push forward and have a chance to survive, or they retreat and die for sure. Stalin was a cruel son of a bitch and issued orders to shoot retreating Soviet troops...
I suggest you ask the Australian Armor and Calvary Museum for any advice needed as they are experts on restoring tanks. If you need any help I'm sure you can just give them a call, as they have their own restored T-34-85.
My guess was the crank had snapped. Had it in a Rolls Royce truck engine and it was still running and it had six cylinders less Some tank engine that when you see inside it

Getting an old eastern block engine just now. You might have to put that on hold for a while. I cannot believe it was still running! Calm in a crisis. Great video.
Even though not for an eternity I have watched enough of what you do to believe that if you can get the parts, you and your crew can fix the T34 and of that I have no doubt. :)
Wow that much damage and it still ran No car engine couod ever do that it shows what kind of design gose into building a tank. Love ur channel keep it up buddy
It's definitely fixable. I've seen Caterpillar engines that look like a pile of scrap get welded back together and run hard for years after. Undersize the crank, align hone the block, shave the piston tops if that makes them come out the deck too much or get new pistons with shorter compression height. Course, you'll need to source oversized bearings for it and maybe fiddle with the timing gear alignment. Most engines are just junked at this point because of the cost to repair, but it definitely can be done on a rare or bespoke unit. Also, I just want to point out that many older engines would also run with catastrophic damage like this. The materials in modern engines are simply engineered to be precisely strong enough to handle the load in ideal conditions. If the conditions vary from ideal (overheating, poor fuel quality, poor fuel flow, stuck injectors, dirty air filter, hauling more weight than designed for, etc), the loads increase past the tolerance of the materials and the engine is just about immediately destroyed. Older engines (especially military and aviation) were expected to operate outside of ideal conditions and, therefore, were built to handle it, cost be damned. Plus, a modern engine trying to make more horsepower on a smaller displacement increases the load on the components and leaves less margin-of-safety in the first place. Over the years, I've met a few old-timers who talked of breaking a crank in half trying to race someone from a traffic light, only to then just drive on home with half or less of the cylinders working.
Its not scrap yet, the main bearing shell locations can be line bored out and new shells made to suit. The crankshaft journals can be spray metalled if they are chewed up. You arent going to be facing the Panzers so you can get away with a repaired engine if you dont rip the arse out of it.
Eh it's roached. The main caps are hammered oblong as hell and that means the block's also way off in the rhubarb. You ain't gonna line-bore and shell a half inch of play out of the main bearings.
@@stephenhunter70 And before you put bearings in you line bore the block and caps so the bearings have round holes to sit in. Only, this block and these caps are so fucked up that you cannot simply line bore it, throw bearings in, and call it a day. To repair this engine you would have to build back up all the wear FIRST, then line bore it standard size, THEN put bearings in it. Given russia is still making this family of engine to this day I dont see the point; these things in one form or another are in T-80s and are anything but rare.
@@stephenhunter70 Hah. Maybe. Truly sad part of it is Russia's straight up unmothballing t62s at this point. I'm pretty sure the engine in a T62 would be a direct bolt in.
holy hell how did it run in that state?! amazing. my theory is that at some point in it's life it was knocked out and then rebuilt hastily in the field from other tanks that were worse off. some serious impact sheared those bolts cleanly like that. great videos guys, keep us in the loop!
You can be sure that this tank was damaged. It is very unlikely that this tank did not participate in the battles. But one day I was at a tank factory where there are several dozen tanks from World War I and World War II. I was incredibly surprised when we rode a very well-preserved T-34 of the first version with a small cannon. A factory employee told me that this tank has never been in combat! This is very strange, because it was in St. Petersburg.
Another amazing video, I think the glue might even work 🙂 And not wanting to educate you, I have to explain anyway, that it is either Czech or Slovak, two different languages, Russian is a completely different one. With the first two I can help, if needed, since I am of the Czech nationality 🙂
Brilliant video and nice hoodie Couldn't watch when you lifted the fan and clutch off 😮 Then the gap on the crank measurement in fingers cracked me up 😅
hello mr hewes love watching your videos i know mastermilo a dutch youtuber has a assortment of rusian tank engines since the V-2 engine that is in your t34 The V-2 engine is a diesel V12 designed by the Soviet Union in the 1930s, and is most famous for powering the hordes of T-34s fielded during the Second World War. However, work on this engine continued on, being used in the T-54, T-62, T-72 and T-90 so he might have a complete botom end for you or spare parts or get you in contact with his supply man
The next time you spin the nuts off studs that hold the oil sump at the bottom of an engine block, put a wooden block between that block and the top of the sump, or oil pan. Be certain that there's a gap between them so that you can put the pry bar between them. This will prevent any damage to the oil sump. Look at the damage you did to the corner of that sump. This will cause oil seepage between those two surfaces.
No, they certainly won't be using that engine, not with that block in such terrible condition. They'll be trying to find another one of them. I'll forgive you for being that obvious about that engine.
one funny information here. T-34 engine still under using in some of T-55, T-62, T-72, T-90 and soviet/russian self propelled artilleries, self propelled mortars, APCs, IFVs, PT-76 floatable light tank. all with modified horsepower set. so you can find it's parts very easily. so if you need some spare part, search for the destroyed one of them and take some engine parts from it.
Just put it back together and run as V11 ;) Might be worth reaching to some Polish places where they keep T34-85. They might have or know where to get a "new" one.
You have to give credit to the Russians for building an amazing engine like the V2, when your goal with a T34 is to always go forward no matter what, the engine damage shows a what a great design it is, the tank can still fight, amazing.
dude, that thing was one high rev away from blowing up, it is a small miracle it didn't, this wasn't going on for hours, more likely happened when he was fiddling with injection pump, he even said one or more injectors were leaking, and what most likely happened, he stopped it, but pressure in rail kept diesel leaking into a cylinder or two, and once he cranked it again, the piston went up and tried to compress that liquid, which it couldn't, and that caused the piston to push the crank down into the caps, the smaller (narrow) ones deformed, the larger one just broke apart there couldn't have been almost any oil pressure, so the damage isn't limited to just the bottom end, but it might be salvageable, he'd become a legend if me made this thing into a reliable engine again, and I hope he does just that, instead of the easy way of getting another one
Russian WW2 records show the V2 engine had a life span of 125 miles under combat conditions I.e. under what is called military power that was needed under combat conditions. The V2 engine was a good engine when not pushed beyond what was needed to get to the rail yard from the factory and from the rail head to frontline positions.
@@fasttruckmanthis isn’t wholly true. By 1943-44, the 6th guards tank army was seeing 250-300hr service intervals on their T-34 engines. This is pretty much the same as the R975 radial found in the Sherman, which in 1945 the army reported would last about 250-300hrs. The Chrysler multi bank when tested at Aberdeen in 44’ ran about 350-400. The V-2 was a fine engine that was on par with engines seen in other comparable tanks. 125 hour is simply wrong by the time it found it’s way into the 34/85
@@HE-162 the air filters were what was killing these engines. Next what was dying was clutch and gearbox. Going further into the war, V-2s were dying less and less mainly because of improvement made to air filters. Whats really funny is that as soviet tanker, you never knew what quality you'll get next as replacement, you could get a tank that drove for 400hrs or you would get one that would fail catastrophically after rolling from the train. V-2 was not in any shape or form on par with engines found in Shermans or even in fkin Panzer 4. They were rushed modernisation of BT-7m engine with pretty much no strengthening made to to push a lot more mass that was found on BT-7. It was not a miracle of an engine, it was exactly what they had on hand, and soviets packed it with all the unsolved problems that it brought with it. They had to solve problems on the go, not before setting up the production. They even fitted some number of T-34 with straight on MT-17.
The forces involved inside an internal combustion engine even on tickover are huge, I could easily see that damage occurring in seconds the moment the rear bearing failed, I don't know what the tickover of a V 12 tank engine is but if you take 500 rpm as a guesstimate that huge,heavy crank is flying round 8 times every second and most of the wear looked very fresh.
Great video , and what a great and reliable engine that run despite of being basically broken. Hope you can find a replacement for it. p. s. was laughing my a. off at the end there🤣😭 24:20
The bronze rings at the clutch end and the front end were labyrinth seals. One part should have fins and the other be smooth. It is often used as an oil retention system for harsh duty as it is more robust than a rubber lip seal. They are still used on big power generation today
That "welcome back" at the beginning, with your new microphone, made you sound like the BBC , The rest could not have been more interesting if it were the opening of an ancient tomb . Excellent!
With the engine oil looking like grey primer I think the engine may have gulped some water. Hydraulicing a cylinder or two that may have sheared the main bearing cap bolts making the crank drop and killed the rear main oil seal. Just a theory. Good luck with the replacement engine.... look forward to the anti-tree hugger smoke screen!
I love watching your videos as we all do but especially liked this one and hope you’re gonna find the time to whip out the crank to show us some more of the damage, I’ll buy you a pack of them ciders you like if ya do it for us 👍 🍻
amazing the thing actually ran... and judging from the state those shells are in from the broken journal, it happen quite a while ago but, I'd still pull the crank and get it checked, if it is reasonably straight and replacement shells could be bought, then the caps could be easily machined on cnc, it is like a zero issue, had I been closer and not a water channel and couple thousand km away, I'd actually offer to 3d scan them and machine new ones for material cost just to see if it could be made run again I mean there is probably some more things to discover on it, but it did run... so I'm guessing it could be repaired to a reasonably reliable state still, if the crank is not all bent out of shape that is
Even if the crank is bent they can straighten it. I bet one of the bearings in the back got bad and put a lot of pressure on those bolts which look no bigger than 5/16’s and that’s what sheared them off and wiped out the rest of the bearings.
@@mikehunt3222 I think there was a leaky injector also somewhere, so could have also been (I don't know the English expression for this) hydraulic "hammer" when the piston couldn't compress all the diesel that leaked into the cylinder
@@dsfs17987 that does sound like the most plausible explanation because that would give it a good shock when trying to compress too much fuel. And we call it hydro locking.
Mastermilo has done a refurbishment of a v12 that looks just like this of his t69 tank. He has a few other v12's laying around aswell. His werkplaatsvlog channel shows some work he has done to the engine
You guys might think that engine is done but it would be gold to a person or organization (with deeper pockets),. Frankly that engine could be rebuilt though it would require some custom casting and machining obviously. I couldn't even guess where one would find head gaskets for that beast!

"Very low hours, runs, drives, hardly smokes" Jack will buy it :)
Loving the journey on this tank and the Minion talkover when you speed it up; currently in hospital and it's keeping my spirits up.
More to the point how did you get hold of one of Lord Mucks hoodies ?
He must hold you in high regard ! Great video mr Hewes 👍
Joe,
Continue to thoroughly enjoy each episode you release especially your explanations of what you are doing. Also, nice to see progress thought each of your individual projects. I may have missed an earlier presentation but it would be nice to know the others that help you out and how they fit into the team. Great you have sourced another engine for the T34. Peter
WOW!!!!! What a great video!!! Never in my wildest dream did I think I’d be walked through the tear down of a WWII T-34 engine which surprisingly suffered a self inflicted catastrophic event that exhibited only minor symptoms!!!
My dad is a WWII vet (Marine, pacific theatre). He said most of the military equipment was designed around a projected lifespan of survival expectancy, i .e. quantity vs. quality was generally the design criteria. The equipment just wasn’t designed to last past its expected use. I don’t know what the expected lifespan of a T-34 tanker is, but I’d bet the T-34 and the Soviet operator had a lot in common on the survivability spreadsheet.
25 hours was considered long in the tooth for them. They were literally considered to be disposable.
@@TestECull Wow! My dad was a B.A.R. operator (Browning Automatic Rifle). He said he was taught to fire short bursts and to never stand (or lay) in the same spot after pulling the trigger to avoid the concentrated fire being returned to neutralize his position. He said he was told prior to his first landing that his life expectancy was under 60 seconds. Hence my dad was notorious for telling us kids that there was only 60 seconds in a minute and we were expected to make each of them count! Also, if you weren’t moving at 60 paces a minute you weren’t moving fast enough! LOL
@@MrSeeuu Stalin's steategy, especially early in Operation Barbarossa, was to *quite literally* clog Tiger tracks with bodies until the Germans had no choice but to turn back. Losses meant nothing to him. A T34 that survived 25 hours of combat was a hero tank and it's a large part of why there are so few 76mm and Zis-S-53 armed T-34s left in the world. They all got blowed up.
@@TestECull Thank you so much for the history lesson. That data just boggles my mind. Trying to comprehend the mindset it took to not see the reality of their situation and continue to move forward under overwhelming statistics of doom is unimaginable. Being 16 years old or so and looking down the barrel of finality, I suspect hope for survival becomes your only attainable strategy. How tragic.
@@MrSeeuu It wasnt a hard choice to make. They either push forward and have a chance to survive, or they retreat and die for sure. Stalin was a cruel son of a bitch and issued orders to shoot retreating Soviet troops...
Master Milo has 2 or 3 engines in his stock.
You never know he may be up for some swaps lol
Jes .master Milo have 4 on Stock
I suggest you ask the Australian Armor and Calvary Museum for any advice needed as they are experts on restoring tanks. If you need any help I'm sure you can just give them a call, as they have their own restored T-34-85.
MASTER MILO he has 5 of those and is in the netherlands.
@@janmachiels5905 he knows how hard it is now to get those engines i think hes not gonna sell one, and they are not the same
@janmachiels5905 hé has spoken mastermilo before about this engine asking questions about it. So i think hé knows how many engines hé has
My guess was the crank had snapped.
Had it in a Rolls Royce truck engine and it was still running and it had six cylinders less
Some tank engine that when you see inside it
Nice to see more detailed mechanical work, and the digging in to see what's wrong.
Your videos are the RUclips highlight of the week! So close to 100K! It’s a testimony to Russian engineering that with all that damage, you still had it running, sort off.😅
But it’s probably the Russian engineering that is the reason it broke in the first place.

@@mikehunt3222 an engine that's been built 80 years when resources were scarce in Russia broke down in 2023? no way, must've been the Russian engineering 🤦♂

Great video, really enthralling. Your comment of “Only one finger in the bottom” rather threw us all off. Clearly she has been round the block a few times!

What a mess! Amazed that thing still ran..
Thanks for another great video. Congrats on 100K subscribers. Cheers from Brisbane Australia
100k subscribers. Good job lads. Really enjoyed this one, looking forward to seeing what you decide to do. The two/one fingers remark cracked me up as well 😂
What a shame. Sorry to see that the main bearings are that worn out. I wish You guys well on Your new quest of finding a replacement engine.
I was on the edge of my seal during the teardown. Really great and well filmed and edited. Interestng to see where you go next. Coolio!!
Getting an old eastern block engine just now. You might have to put that on hold for a while. I cannot believe it was still running! Calm in a crisis. Great video.
Hi Joe, I've looking forward to this video!! Away we go!!! Ah, what a shame, tough break. John
Keep up the good work. You guys are awesome.
Whilst it was last still running, you could have dropped an egg into the sump, it seems to work on radiators
Brilliant video as always
And that thing still ran. Incredible !
(I Wonder how many more miles it would av ran for.)
Thanks for the video mr Hughes
That is an impressive piece of engineering, respect. Considering it's so old. I hope you can get the tank running again, cheers from Finland :)
Your expansive array of fire extinguishers is confidence inspiring.
They have them for a reason. They had a bit of an incident earlier lol
Genuinly impressive that it ran for as long as it did.
Even though not for an eternity I have watched enough of what you do to believe that if you can get the parts, you and your crew can fix the T34 and of that I have no doubt. :)
Wow that much damage and it still ran
No car engine couod ever do that
it shows what kind of design gose into building a tank.
Love ur channel keep it up buddy
It's definitely fixable. I've seen Caterpillar engines that look like a pile of scrap get welded back together and run hard for years after. Undersize the crank, align hone the block, shave the piston tops if that makes them come out the deck too much or get new pistons with shorter compression height. Course, you'll need to source oversized bearings for it and maybe fiddle with the timing gear alignment. Most engines are just junked at this point because of the cost to repair, but it definitely can be done on a rare or bespoke unit.
Also, I just want to point out that many older engines would also run with catastrophic damage like this. The materials in modern engines are simply engineered to be precisely strong enough to handle the load in ideal conditions. If the conditions vary from ideal (overheating, poor fuel quality, poor fuel flow, stuck injectors, dirty air filter, hauling more weight than designed for, etc), the loads increase past the tolerance of the materials and the engine is just about immediately destroyed. Older engines (especially military and aviation) were expected to operate outside of ideal conditions and, therefore, were built to handle it, cost be damned. Plus, a modern engine trying to make more horsepower on a smaller displacement increases the load on the components and leaves less margin-of-safety in the first place. Over the years, I've met a few old-timers who talked of breaking a crank in half trying to race someone from a traffic light, only to then just drive on home with half or less of the cylinders working.
Its not scrap yet, the main bearing shell locations can be line bored out and new shells made to suit. The crankshaft journals can be spray metalled if they are chewed up. You arent going to be facing the Panzers so you can get away with a repaired engine if you dont rip the arse out of it.
Eh it's roached. The main caps are hammered oblong as hell and that means the block's also way off in the rhubarb. You ain't gonna line-bore and shell a half inch of play out of the main bearings.
@@TestECull The shells all need to be replaced, not line bored.
@@stephenhunter70 And before you put bearings in you line bore the block and caps so the bearings have round holes to sit in. Only, this block and these caps are so fucked up that you cannot simply line bore it, throw bearings in, and call it a day. To repair this engine you would have to build back up all the wear FIRST, then line bore it standard size, THEN put bearings in it. Given russia is still making this family of engine to this day I dont see the point; these things in one form or another are in T-80s and are anything but rare.
@@TestECull Me neither maybe the communications breakdown right now with Russia might have a bearing on it.
@@stephenhunter70 Hah. Maybe. Truly sad part of it is Russia's straight up unmothballing t62s at this point. I'm pretty sure the engine in a T62 would be a direct bolt in.
Compulsive viewing - thank you and looking forward to seeing if a decent replacement can be sourced.
Almost 100k! And as always amazing video!
holy hell how did it run in that state?! amazing. my theory is that at some point in it's life it was knocked out and then rebuilt hastily in the field from other tanks that were worse off. some serious impact sheared those bolts cleanly like that. great videos guys, keep us in the loop!
You can be sure that this tank was damaged. It is very unlikely that this tank did not participate in the battles. But one day I was at a tank factory where there are several dozen tanks from World War I and World War II. I was incredibly surprised when we rode a very well-preserved T-34 of the first version with a small cannon. A factory employee told me that this tank has never been in combat! This is very strange, because it was in St. Petersburg.
A masterclass in taking things apart. And with each step more horrors revealed.
Whatever I expected of today. It wasn't seeing a T34 engine get taken apart so thank you very much for making my day.
Thanks always learn something new from your great videos I have had 2 engines go bang that was some going Mr Hewes
Another amazing video, I think the glue might even work 🙂 And not wanting to educate you, I have to explain anyway, that it is either Czech or Slovak, two different languages, Russian is a completely different one. With the first two I can help, if needed, since I am of the Czech nationality 🙂
Such a shame the Tonk was running so nice!!
Hope you can find a good one thats not so expensive
Brilliant video and nice hoodie
Couldn't watch when you lifted the fan and clutch off 😮
Then the gap on the crank measurement in fingers cracked me up 😅
Разбитые пастели вкладышей двигали танк!!!! ПОТРЯСАЮЩЕ!!!
You do know
.you can get a T34.TANK.MANUAL.FROM HAYNES..YES THATS CORRECT. I JUST GOOGLED IT.AND ITS IN ENGLISH.😅
hello mr hewes love watching your videos i know mastermilo a dutch youtuber has a assortment of rusian tank engines since the V-2 engine that is in your t34 The V-2 engine is a diesel V12 designed by the Soviet Union in the 1930s, and is most famous for powering the hordes of T-34s fielded during the Second World War. However, work on this engine continued on, being used in the T-54, T-62, T-72 and T-90 so he might have a complete botom end for you or spare parts or get you in contact with his supply man
From previous video's Mr. Hewes knows Milo and has contacted him for this tank and it's engine timing issues.
Congrats! These explanatory videos are great!
You are absolutely correct. There is some main bearing failure. One rear bearing even came off. You need to turn the crank and get new main bearings.
The next time you spin the nuts off studs that hold the oil sump at the bottom of an engine block, put a wooden block between that block and the top of the sump, or oil pan. Be certain that there's a gap between them so that you can put the pry bar between them. This will prevent any damage to the oil sump. Look at the damage you did to the corner of that sump. This will cause oil seepage between those two surfaces.
They are not going to re use the sump I think it's busted.
No, they certainly won't be using that engine, not with that block in such terrible condition. They'll be trying to find another one of them. I'll forgive you for being that obvious about that engine.
How the living F"*% was that running and sounding so good, it was trashing itself ????
Whew, when you first started yanking on that squirrel cage fan with your feet under it I was nervous! So glad you decided it was heavy!
one funny information here. T-34 engine still under using in some of T-55, T-62, T-72, T-90 and soviet/russian self propelled artilleries, self propelled mortars, APCs, IFVs, PT-76 floatable light tank. all with modified horsepower set. so you can find it's parts very easily. so if you need some spare part, search for the destroyed one of them and take some engine parts from it.
Definately want to see you pull the crank on that!
North Korea has tons of spare engines ask uncle Kim .
Absolutely enjoy seeing the nuts and bolts (or the lack there of) of a piece of history.
This is an awesome channel!! Figure it out as you go along, love it! Cheers!!!
I knew it was serious when you used two exclamation marks in the title ... 8-(
Just put it back together and run as V11 ;)
Might be worth reaching to some Polish places where they keep T34-85. They might have or know where to get a "new" one.
I knew they were tough, but this is crazy as it ran when in bits , unbelievable , maybe the fastrack engine will fit😊
thats the least drippy, dirty cleanest crankcase engine I've ever seen
You have to give credit to the Russians for building an amazing engine like the V2, when your goal with a T34 is to always go forward no matter what, the engine damage shows a what a great design it is, the tank can still fight, amazing.
dude, that thing was one high rev away from blowing up, it is a small miracle it didn't, this wasn't going on for hours, more likely happened when he was fiddling with injection pump, he even said one or more injectors were leaking, and what most likely happened, he stopped it, but pressure in rail kept diesel leaking into a cylinder or two, and once he cranked it again, the piston went up and tried to compress that liquid, which it couldn't, and that caused the piston to push the crank down into the caps, the smaller (narrow) ones deformed, the larger one just broke apart
there couldn't have been almost any oil pressure, so the damage isn't limited to just the bottom end, but it might be salvageable, he'd become a legend if me made this thing into a reliable engine again, and I hope he does just that, instead of the easy way of getting another one
Russian WW2 records show the V2 engine had a life span of 125 miles under combat conditions I.e. under what is called military power that was needed under combat conditions. The V2 engine was a good engine when not pushed beyond what was needed to get to the rail yard from the factory and from the rail head to frontline positions.
Many engines will keep running for a short while with major damage. It's nothing to do with Russian engineering.
@@fasttruckmanthis isn’t wholly true. By 1943-44, the 6th guards tank army was seeing 250-300hr service intervals on their T-34 engines. This is pretty much the same as the R975 radial found in the Sherman, which in 1945 the army reported would last about 250-300hrs. The Chrysler multi bank when tested at Aberdeen in 44’ ran about 350-400.
The V-2 was a fine engine that was on par with engines seen in other comparable tanks. 125 hour is simply wrong by the time it found it’s way into the 34/85
@@HE-162 the air filters were what was killing these engines. Next what was dying was clutch and gearbox. Going further into the war, V-2s were dying less and less mainly because of improvement made to air filters. Whats really funny is that as soviet tanker, you never knew what quality you'll get next as replacement, you could get a tank that drove for 400hrs or you would get one that would fail catastrophically after rolling from the train.
V-2 was not in any shape or form on par with engines found in Shermans or even in fkin Panzer 4. They were rushed modernisation of BT-7m engine with pretty much no strengthening made to to push a lot more mass that was found on BT-7. It was not a miracle of an engine, it was exactly what they had on hand, and soviets packed it with all the unsolved problems that it brought with it. They had to solve problems on the go, not before setting up the production. They even fitted some number of T-34 with straight on MT-17.
Well, something must have been wrong for a very long time. This isn’t damage from half an hour. Good luck finding a new one guys!
The forces involved inside an internal combustion engine even on tickover are huge, I could easily see that damage occurring in seconds the moment the rear bearing failed, I don't know what the tickover of a V 12 tank engine is but if you take 500 rpm as a guesstimate that huge,heavy crank is flying round 8 times every second and most of the wear looked very fresh.
Great video , and what a great and reliable engine that run despite of being basically broken. Hope you can find a replacement for it.
p. s. was laughing my a. off at the end there🤣😭 24:20
The bronze rings at the clutch end and the front end were labyrinth seals. One part should have fins and the other be smooth. It is often used as an oil retention system for harsh duty as it is more robust than a rubber lip seal. They are still used on big power generation today
‘Struggle to get one finger in the bottom’ 🤭.

That "welcome back" at the beginning, with your new microphone, made you sound like the BBC , The rest could not have been more interesting if it were the opening of an ancient tomb . Excellent!
Hopefully you will find a suitable engine. Cheers from Australia 🇦🇺
With the engine oil looking like grey primer I think the engine may have gulped some water. Hydraulicing a cylinder or two that may have sheared the main bearing cap bolts making the crank drop and killed the rear main oil seal. Just a theory. Good luck with the replacement engine.... look forward to the anti-tree hugger smoke screen!
It's not always a bad thing to be able to fit 2 in the top and 1 In the bottom 😂😂
I knew it wouldn’t just be me that wanted to comment on that… 😂
Me too! Started laughing as soon as he said it.

Top tip: When bringing dormant engines back to life, the oil pressure gauge is your friend.
I love watching your videos as we all do but especially liked this one and hope you’re gonna find the time to whip out the crank to show us some more of the damage, I’ll buy you a pack of them ciders you like if ya do it for us 👍 🍻
Мы построили эти танки для боя не для того, чтобы прослужить долго. Спасибо за восстановление нашего старого танка.
Все так. И этот В2 дал старт большой серии моторов которые до сих пор крутятся например в маленьких тепловозах на узкоколейках.
amazing the thing actually ran... and judging from the state those shells are in from the broken journal, it happen quite a while ago
but, I'd still pull the crank and get it checked, if it is reasonably straight and replacement shells could be bought, then the caps could be easily machined on cnc, it is like a zero issue, had I been closer and not a water channel and couple thousand km away, I'd actually offer to 3d scan them and machine new ones for material cost just to see if it could be made run again
I mean there is probably some more things to discover on it, but it did run... so I'm guessing it could be repaired to a reasonably reliable state still, if the crank is not all bent out of shape that is
Even if the crank is bent they can straighten it. I bet one of the bearings in the back got bad and put a lot of pressure on those bolts which look no bigger than 5/16’s and that’s what sheared them off and wiped out the rest of the bearings.
@@mikehunt3222 I think there was a leaky injector also somewhere, so could have also been (I don't know the English expression for this) hydraulic "hammer" when the piston couldn't compress all the diesel that leaked into the cylinder
@@dsfs17987 that does sound like the most plausible explanation because that would give it a good shock when trying to compress too much fuel. And we call it hydro locking.
@@mikehunt3222 locking, don't know why I couldn't remember that, thank you.
@@dsfs17987 probably just a brain fart. I get lots of those the older I get.
Mastermilo has done a refurbishment of a v12 that looks just like this of his t69 tank. He has a few other v12's laying around aswell. His werkplaatsvlog channel shows some work he has done to the engine
You guys might think that engine is done but it would be gold to a person or organization (with deeper pockets),. Frankly that engine could be rebuilt though it would require some custom casting and machining obviously. I couldn't even guess where one would find head gaskets for that beast!
