That bearing liner didn't look to be much chewed up at all. That makes me think that the grease gorilla that last worked on that engine was told "tighten the bolts until you hear a click", but he didn't have a torque wrench.

@@user-re5mj9ww9o Sigh. You completely misinterpreted what I said. Given the fantasy news and history climate there at the moment, I'm not really surprised. By "gorilla" I meant a large, strong, but not necessarily bright man. In this case I postulated that he was given instructions, but the wrong tools. He followed the instructions to the letter, but got bad results by not knowing he was using the wrong tools. In case you still think I'm making fun of Russians, I'll point out two things: 1. "Gorilla" is VERY commonly used in this exact sense in the English world to describe ANY worker, English, American, or other, that acts this way. 2. This engine was rebuilt not too long ago, most likely by someone in the UK. Therefore this 'gorilla' would be English, not Russian.

There known for catching fires. Especially during WWII, the fact that it was running and driving a few months ago is "MIND BLOWING"! That crap oil should of made the tank run like shit...or not run at all.... surprised it didn't turn into Tar/sludge.
If the engine was used during combat conditions it would have failed within minutes. It's evident this engine like most WW2 tanks still in working order today are never used under what is called military power, power needed to charge across a battlefield.
If we knew anything about the story/history of this named T-34-85 than we would know if it was abused and mistreated or was really in a war/battle. If anything, this could be a T-34-85 that never made it to the front because the war ended, or its factory was damaged/destroyed.

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.
@@andrewsmart2949it’s not something you have to bear the weight for, nor should. Don’t forgot how it originally started. Not his fault nor is it yours nor is it mine. The world is beautiful
Any tank engine will continue running while damaged if not used at it's full military power I.e. the engine power needed to charge across a battlefield.
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. So, unfortunately, a good makeover of such an engine would have to include not just replacing some dough-grade bolts and shitty hoses but effectively reengineering some stuff. That's what you get when you take a BMW VI aircraft gasoline engine, make a tank gasoline engine out of it (M-17), then turn it into a diesel high-RPM engine.
People like to rip on the methods in Pakistan but the results are undeniable. They just make stuff work. Absolutely no tooth paste in the tube when they are done.
Totally correct. Scroll seals in my old engineering books. BMC A and B series engine used them. Oil tight until you stopped overnight and then you had a puddle. Also known as rust preventative system. Brit motorcycles used them as well. Hence the joke that you checked your bike had oil by inserting your toecap underneath.

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.

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

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
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.
Your detailed evaluation of the engine and its components during teardown provides us with an excellent example of "automotive archaeology." One can't help but appreciate how the Russians cranked out these tanks in great numbers given the challenges and limitations created by rudimentary production processes and inconsistent quality in raw materials and components! 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!
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!
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
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 😂
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
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. :)
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.
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.
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 😅
I served my Apprenticeship on The Spanners in The 1970s. I have worked on most of the commercial Engines that are out there and I don't think that I have ever seen an Engine with that much scrap Metal in the Sump as this one. That was something else.
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 🙂
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.
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.
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 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
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 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.
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.
There basically the same engine used in most soviet tanks and is still used in the T90. Of course, parts are in a bit of demand at the moment for some reason.
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 👍 🍻

I am loving the restoration of the t34
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
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
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 👍
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.
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.
Your detailed evaluation of the engine and its components during teardown provides us with an excellent example of "automotive archaeology." One can't help but appreciate how the Russians cranked out these tanks in great numbers given the challenges and limitations created by rudimentary production processes and inconsistent quality in raw materials and components! 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!
All of a sudden I hear Moriarty from Kelly's Heroes exclaiming "It's a piece of junk!!"
MasterMilo has some spare engines lying around 👍
Werkplaatsvlog is the channel name but i think he already knows Emile
@@rjansen6874 the MasterMilo channel still exist .
@@Bus2000 Yes indeed but they not post as often as the other channel
And that thing still ran. Incredible !
(I Wonder how many more miles it would av ran for.)
Thanks for the video mr Hughes
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!
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
"Very low hours, runs, drives, hardly smokes" Jack will buy it :)
Hi Joe, I've looking forward to this video!! Away we go!!! Ah, what a shame, tough break. John
Compulsive viewing - thank you and looking forward to seeing if a decent replacement can be sourced.
What a mess! Amazed that thing still ran..
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!!
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 😂
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
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
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. :)
Thanks for another great video. Congrats on 100K subscribers. Cheers from Brisbane Australia
Your expansive array of fire extinguishers is confidence inspiring.
They have them for a reason. They had a bit of an incident earlier lol
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.
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 :)
Almost 100k! And as always amazing video!
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.
Genuinly impressive that it ran for as long as it did.
Congrats! These explanatory videos are great!
Thanks always learn something new from your great videos I have had 2 engines go bang that was some going Mr Hewes
Such a shame the Tonk was running so nice!!
Hope you can find a good one thats not so expensive
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.
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 😅
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.
Definately want to see you pull the crank on that!
You do know
.you can get a T34.TANK.MANUAL.FROM HAYNES..YES THATS CORRECT. I JUST GOOGLED IT.AND ITS IN ENGLISH.😅
I served my Apprenticeship on The Spanners in The 1970s. I have worked on most of the commercial Engines that are out there and I don't think that I have ever seen an Engine with that much scrap Metal in the Sump as this one. That was something else.
Whatever I expected of today. It wasn't seeing a T34 engine get taken apart so thank you very much for making my day.
How the living F"*% was that running and sounding so good, it was trashing itself ????
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 🙂
I knew they were tough, but this is crazy as it ran when in bits , unbelievable , maybe the fastrack engine will fit😊
This is an awesome channel!! Figure it out as you go along, love it! Cheers!!!
North Korea has tons of spare engines ask uncle Kim .
A masterclass in taking things apart. And with each step more horrors revealed.
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!
thats the least drippy, dirty cleanest crankcase engine I've ever seen
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.
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.
Absolutely enjoy seeing the nuts and bolts (or the lack there of) of a piece of history.
how fucked up is fucked up?
T-34 engine: thats fucked up
I knew it was serious when you used two exclamation marks in the title ... 8-(
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.
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
With out a doubt the most interesting vid I have seen in a long time! 🙂
‘Struggle to get one finger in the bottom’ 🤭.
Kharkiv model V-2 coffee table. 👍
Another superb video Joe.
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
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.
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.
Hopefully you will find a suitable engine. Cheers from Australia 🇦🇺
I admire your knowledge for a woopasnapper😂brilliant you all work together like a well oiled machine.
Looks like the crankshaft bearing bolts were over torqued
Too many ugga duggas.
Can you even get new parts or new old stock for them. Good luck man
There basically the same engine used in most soviet tanks and is still used in the T90. Of course, parts are in a bit of demand at the moment for some reason.
@@spodula I know were to get parts get . Should be lots
