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.

“2 (fingers) in the top but only 1 in the bottom” the missus thought that was hilarious 😂😂

I mean to be fair keeping running even when catastrophically damaged is *exactly* what you want out of a tank engine!

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.

Dude, your channel is awesome! I used to be a Diesel mechanic that worked on heavy equipment and big rigs up until I got too sick to work. Your content brings back a lot of great memories, I seriously cant wait to be out of this bed and back to work. Until then I got yall to thank for many hours of entertainment and teaching me some new techniques ill be trying out as soon as i get back in the shop! Much love and respect from Denver, Colorado :D

Crank bearing clearances are normally measured in thousandths of an inch. This one's measured in fingers!

It's a testament to the durability of the machine that even with that level of engine damage it kept on running 😊😮

This channel is rather special.... Not just the content but the way you present the content as well. Great stuff!

The half laugh half anguished cry from you is truly haunting. . . I'm impressed at your Stoicism. I would be weeping

Watching you pull that giant fan off the crank was the most genuinely suspenseful thing I have seen in a long time...😳

2 fingers in the top and stuggle with one in the bottom, hey. Yeah, I think a lot of us can relate to that.

It didn't sound that bad at all. Amazing with that much internal damage. That's one tuff old SOB!

A street mechanic from Pakistan would weld that broken piece back on and have that engine running in no time , I've watched their repair video's

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.

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.

Glad to see/hear the body mic. Nice move.

Wow that is unbelievable it was running and driving in the tank with that amount of damage

I'd take it to a skilled engine machinist, you never know, they could fix it by machining new parts, welding them on and regrinding. I've seen skilled guys do amazing things to fix engines.

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.

Just discovered your channel last week and it’s totally unique. Great content, great banter with everyone.

as Joe was pulling the fan / flywheel / clutch assembly off the crank .. i'm sure i wasn't the only person thinking ' that looks hell of a heavy .. break out the fork-lift & an endless loop '

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 🤞🙏

Nice to see more detailed mechanical work, and the digging in to see what's wrong.

I love that the crank has so much play that the piston skirts have hit the engine casting below🤣

How impressive for an engine its age, completely destroyed major components while not sizing operations. Did exactly what a Tank engine should, taken major damage while it keeps the vehicle moving. Hopefully you can find an engine you can use, I'm a huge fan of this project and would love to see that vehicle moving under its own power again.

All of a sudden I hear Moriarty from Kelly's Heroes exclaiming "It's a piece of junk!!"

I can’t believe it even ran with all that engine damage 😂😂

I am loving the restoration of the t34

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.

That seal is probably a labyrinth seal. Designed to seal using centrifugal force. Very common on old engines

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

Your videos are the KZfaq 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.😅

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.

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 👍

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.

"Very low hours, runs, drives, hardly smokes" Jack will buy it :)

The three ball clutch lift bearing system was used by Triumph / BSA on the clutch of the Trident motorcycles.

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.

What a mess! Amazed that thing still ran..

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.

MasterMilo has some spare engines lying around 👍

Master Milo has 2 or 3 engines in his stock. You never know he may be up for some swaps lol

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!

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. :)

Keep up the good work. You guys are awesome.

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!!

Congrats! These explanatory videos are great!

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!

Genuinly impressive that it ran for as long as it did.

Your expansive array of fire extinguishers is confidence inspiring.

Compulsive viewing - thank you and looking forward to seeing if a decent replacement can be sourced.

Whatever I expected of today. It wasn't seeing a T34 engine get taken apart so thank you very much for making my day.

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

You do know .you can get a T34.TANK.MANUAL.FROM HAYNES..YES THATS CORRECT. I JUST GOOGLED IT.AND ITS IN ENGLISH.😅

And that thing still ran. Incredible ! (I Wonder how many more miles it would av ran for.) Thanks for the video mr Hughes

Hi Joe, I've looking forward to this video!! Away we go!!! Ah, what a shame, tough break. John

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.

Definately want to see you pull the crank on that!

Thanks always learn something new from your great videos I have had 2 engines go bang that was some going Mr Hewes

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

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!

I knew it was serious when you used two exclamation marks in the title ... 8-(

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 😂

Such a shame the Tonk was running so nice!! Hope you can find a good one thats not so expensive

North Korea has tons of spare engines ask uncle Kim .

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 :)

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.

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.

Almost 100k! And as always amazing video!

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 😅

How the living F"*% was that running and sounding so good, it was trashing itself ????

‘Struggle to get one finger in the bottom’ 🤭.

Absolutely enjoy seeing the nuts and bolts (or the lack there of) of a piece of history.

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

Kharkiv model V-2 coffee table. 👍

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 🙂

Keep up the awesome videos. From Australia

This is an awesome channel!! Figure it out as you go along, love it! Cheers!!!

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

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.

Loving the sweatshirt, “ Lord Muck “!

Another superb video Joe.

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.

thats the least drippy, dirty cleanest crankcase engine I've ever seen

I knew they were tough, but this is crazy as it ran when in bits , unbelievable , maybe the fastrack engine will fit😊

Мы построили эти танки для боя не для того, чтобы прослужить долго. Спасибо за восстановление нашего старого танка.

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

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.

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!

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!

That engine looks saveable with new main caps if you could make oversized bearings for it. If it doesn't actually have poured babbit bearings

Разбитые пастели вкладышей двигали танк!!!! ПОТРЯСАЮЩЕ!!!

Amazing it ran!. Just goes to show!. Great vid. Nuff said!. 🙂

It's not always a bad thing to be able to fit 2 in the top and 1 In the bottom 😂😂

Can you even get new parts or new old stock for them. Good luck man

Wow. Properly knackered.

With out a doubt the most interesting vid I have seen in a long time! 🙂
