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.
Ты кого называешь гориллой? Это была война Русские люди работали на износ по 20 часов чтобы разбить фашистскую Германию так же работали и дети на сборке танков. Не следует тебе так выражаться, поостерегись
@@Александрович-ф7щ 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.

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.
@@fasttruckman And it still probably would have outlived the rest of the tank. Stalin's doctrine was, quite literally, just throw tanks at the problem until it sorts out. T-34s were considered disposable and one that survived more than 2 or 3 engagements might as well be considered a hero vehicle. IIRC they didnt even have maintenance intervals because they weren't expected to live long enough to reach their first PM service to begin with.
Mastermilo did a full restore on one of these and still couldn’t get it running properly. Think it kept not firing on a bunch of cylinders. Not to mention the excess valve clearance which leads to these becomes smoke generators. They didn’t have seals, so they make some smoke, but not like you see when these run nowadays. Badass engines. Would never want to have to fix one on a schedule or have to move it… they are in the Netherlands I believe and it took them 2 years and a company’s bank account to get theirs running. Theirs was in worse shape but ended up getting a replacement about the same quality as this. Works of art. Kinda like old rocket engines, that can’t be produced anymore

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.
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.

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
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.

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!
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.
@@1chish I used to race a yamaha TZ750 two stroke 4 cyl in the days. They used to have labyrinth seals between the cylinders. The more air you pumped, the more effective they became. Never gave me any trouble running at 10500 revs.

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. :)
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.
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
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 😂
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.
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
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.
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.
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!
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.
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 🙂
Still looking for an engine here in Manchester............. When that panther tank is gaining on you...this is all you need.... Nothing like a good sandwich length strip down vid....👍 N x
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.
Absolute gutter, and after all the faffing with the fuel pump too. Mind you, you’ve got the knowledge now, and a few decent spares, so hopefully if you source another engine, it’ll all come good.
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.
A but if a far shot But maybe - It was being field repaired and was struck by an 88mm shell - obviously failed to detonate but shook the internals a tad. So, gulp of vodka bit if putty and paint re fitted and off to play against the Panzers and Tigers. Should have been noted in the service logs lol. Loving your videos. High respect and regards to you all.
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.
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.
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.

Quite impressive indeed although that is precisely the level of reliability of a tank engine, that should be able to run till it's last breath.
Well at least the crankshaft was not seized at all !!! It had plenty of play to run freely😄
Well, the best-projected runtime for V-2 engines was 1000 hours, the typical worst - 300 hours. So it doesn't seem like a huge surprise.

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!
That seal is probably a labyrinth seal. Designed to seal using centrifugal force. Very common on old engines
You Sir, are correct.
I call them screw seal.
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.
@@1chish I used to race a yamaha TZ750 two stroke 4 cyl in the days. They used to have labyrinth seals between the cylinders. The more air you pumped, the more effective they became. Never gave me any trouble running at 10500 revs.
Still found in the sectional shaft seals of a lot of turbine engines, though more modern engines tend to use brush seals where possible.
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!
I am loving the restoration of the t34
All of a sudden I hear Moriarty from Kelly's Heroes exclaiming "It's a piece of junk!!"
OMG, I can imagine the same thing!!!!!!!!!!!!!
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 👍
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. :)
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.
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 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!!
Compulsive viewing - thank you and looking forward to seeing if a decent replacement can be sourced.
"Very low hours, runs, drives, hardly smokes" Jack will buy it :)
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.
Your expansive array of fire extinguishers is confidence inspiring.
They have them for a reason. They had a bit of an incident earlier lol
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 :)
I can’t believe it even ran with all that engine damage 😂😂
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
The firing of each cylinder would have been like hammer blows to the crankshaft.
It did well to keep running.
Hope a replacement can be found 🤞🙏
Thanks for another great video. Congrats on 100K subscribers. Cheers from Brisbane Australia
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.
@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
Whatever I expected of today. It wasn't seeing a T34 engine get taken apart so thank you very much for making my day.
What a mess! Amazed that thing still ran..
Thanks always learn something new from your great videos I have had 2 engines go bang that was some going Mr Hewes
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
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 😂
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
Loving the sweatshirt, “ Lord Muck “!
MasterMilo has some spare engines lying around 👍
@@rjansen6874 the MasterMilo channel still exist .
Genuinly impressive that it ran for as long as it did.
Top tip: When bringing dormant engines back to life, the oil pressure gauge is your friend.
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.
Every time these ancient buggers get pulled out of some random places and THEY STILL WORK with a bit of elbow grease. IT'S ALIIIIIVEEE!!!
Разбитые пастели вкладышей двигали танк!!!! ПОТРЯСАЮЩЕ!!!
Almost 100k! And as always amazing video!
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
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!
Keep up the good work. You guys are awesome.
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.
A masterclass in taking things apart. And with each step more horrors revealed.
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!
Jesus christ that fan assembly was huge!
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.
That end clip, maybe it's the audio processing, but I can almost hear the thing giving itself an internal shave🤣
How the living F"*% was that running and sounding so good, it was trashing itself ????
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!
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.
Hopefully you will find a suitable engine. Cheers from Australia 🇦🇺
Such a shame the Tonk was running so nice!!
Hope you can find a good one thats not so expensive
This is an awesome channel!! Figure it out as you go along, love it! Cheers!!!
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 🙂
Absolutely enjoy seeing the nuts and bolts (or the lack there of) of a piece of history.
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.
Still looking for an engine here in Manchester.............
When that panther tank is gaining on you...this is all you need....
Nothing like a good sandwich length strip down vid....👍
N x
Kharkiv model V-2 coffee table. 👍
I knew they were tough, but this is crazy as it ran when in bits , unbelievable , maybe the fastrack engine will fit😊
‘Struggle to get one finger in the bottom’ 🤭.
This is one of your best videos 😂 sorry that’s it’s knackered but a great video!
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.
Giggidy
With out a doubt the most interesting vid I have seen in a long time! 🙂
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.
Congrats! These explanatory videos are great!
The three ball clutch lift bearing system was used by Triumph / BSA on the clutch of the Trident motorcycles.
Personally I love it
@@MrHewes I was looking forward to seeing how many times a BB drops out while reassembling 😉
Absolute gutter, and after all the faffing with the fuel pump too.
Mind you, you’ve got the knowledge now, and a few decent spares, so hopefully if you source another engine, it’ll all come good.
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.
A but if a far shot But maybe -
It was being field repaired and was struck by an 88mm shell - obviously failed to detonate but shook the internals a tad.
So, gulp of vodka bit if putty and paint re fitted and off to play against the Panzers and Tigers.
Should have been noted in the service logs lol.
Loving your videos.
High respect and regards to you all.
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.
Keep up the awesome videos. From Australia
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
