I will never get over that the old engine ran pretty well. The staggering amount of internal damage it took and continued to function is a testament to both the machine and the people who built it.

It is nice to see that there are still young people with brains that are willing to use it and work hard.

if you warm the pistons up the Gudgeon pins will slide out. They are designed to float and the soft aluminium pads thrust against the bore.

My father had a 1947 Morris Commercial Cars Parcel Van (MCC PV) with a 2 ltr 4 cylinder Petrol engine. I still have a place in my heart for that van, he converted it into a kind of camper and we had fabulous holidays all through the 60s as kids. The mains on that crank were toast, you could lift the crank up and down a good 1/8” but it still ran fine, if not a bit clunky. One winter, we decided to pull the crank to replace the bearings, but to our disappointment, this engine didn’t have shelled bearings, the block was white-mettalled, so the only way to fix it was to replace the white metal. Dad never gave up, so he’s there with a blow-torch melting white metal onto the big end caps and the block, and paring them down to size with his penknife to make them match with the crank 😳. He got there (luckily there were only 3 main bearings) using jewelers rouge as a guide when he was getting close, and after - the engine ran so sweetly 🤣

This channel has quickly become one of my faves. You didn’t get this kind of content on Combat Dealers with Brucey Compton that’s for sure. I’d love to come and help out sometime pulling things apart and putting them back together. Great satisfaction.

Love the "field-engineering" solution. Rebuilt my Suzuki 185 engine as a teenager, and forgot to fit the gudgeon pin circlips. Grooves, is it? Oh, we had grooves. Filled 'em with JB Weld, sanded down with a flapwheel on a drill, and it started first kick. Lasted about 40 miles, before the epoxy fell out. Never ran again.

The retaining pins on the rods are taper pin. So make sure you put them in from the right side and the right way round 😂

If dry ice is easier to come by in your area, acetone/dry ice bath works pretty well as the poor man's LN2 in many use cases.

More interesting and enjoyable than 99% of everything else on KZfaq. Well done chaps 👌

also a tip (learned from Milo (as he learned from the Dirty Dozen team)): when re-assembling: set the engine vertically: it 'eases' to put in the pistons and rings in place

Cooking dinner whilst watching the lads do a days work is becoming a staple in my life. keep it up! x

You guys are so lucky to have the land/skill / and / passion to do what a lot of us watching want that's why we appreciate you sharing what you doing so many thanks for the videos and the best of luck in your Quest.

Beautiful to see an old engine design like this come a part.

01:59 I can't tell you how nostagic hearing that tune just made me feel! Fuck... has it really been 25 years?

After the fall of the iron curtain lots of spairs for russian tanks where left in storage. A guy who had one of these engines at a tractor pulling event said he got his new in a crate from Lithuania where they had dozens still boxed .if you try the tractor pulling crew they might have a lead on one

It's really interesting to see the inside of the old t34 engine.

Absolutely love these videos on this military equipment, especially the tanks! Keep it up and thanks for sharing!

You have a main rod connected directly to the big end cap and a shorter slave rod connected with a gugeon pin on the other side. Usually u take gugeon pin out of the slave rod first then flip the big end cap for access. Try heating the pistons with a blow lamp instead of cooling the gudgeon pin, we stick the pistons in a parts washer at 80'c for 20 mins at work

Well done Jack!! Keep up the good work chaps, the old girl will be running in no time. Warm the pistons in the oven(the Mrs will love it). Put the pins in the freezer and only take one out at a time. The sump cracks can be welded by a competent welder and given the good compression the mid block and heads look like they will make for a good swap. Be careful to make sure you work out the piston to head clearance as it will be pretty much game over if you get it wrong.

Liquid nitrogen is probably a bit harsh for the pin, you can introduce cold cracks into hardened surface of the pin. It is about -196C. A better bet would be dry ice (solid CO2) which is only -93C and does not lower the pin below the micro cracking region. If you are still stuck for temperature differential, warm the piston up with boiling water which will give you another 90+C of temperature differential. In Oz we can buy dry ice from BOC, might be the same in the UK. If not you can make your own, you just need an old sock and a CO2 cylinder. Attach the sock over the outlet valve of the cylinder securely and open the valve. The rapid expansion of the gas freezes the sock which then precipitates the CO2 into solid and you end up with a sock full of dry ice. When you use a CO2 extinguisher, the white cloud is the water from the air frozen into very small droplets encased in dry ice.

Another great video! Thanks for taking the time to do everything involved making videos!They’re extremely entertaining and you give insight and knowledge of working on tanks and such.

I am sat watching this with the all the faith in the world that should I ever have to fix a T35 block and engine I can sleep at night knowing I will be able to . And I am a carpet fitter ..... love that's guys

so this tank survived WWII and whatever Germany threw at it, suppressed attempted uprisings in eastern europe, kept stalin in power, the cold war, and neglectful ownership but it couldn't survive a few weeks at your shop? Congrats! you are the most dangerous thing this tank has ever faced xD love you guys!

Another totally fascinating episode, sooooo looking forward to how the new engine will take shape. Thanks guys. 👍🏻😊

Top notch entertainment! Keep up the good work guys! :)

Great work team, looking forward to your next epic episode..

Always lovely seeing you guys work

Praying for a speedy recovery❤❤❤

I'm glad I found your channel as there are not many out there showing this sort of stuff 👏

Brilliant lads, fingers crossed for you that everything is interchangeable and, works ok🤞☺

The workings of engines and other things mechanical is a mystery to me, so why I am I so fascinated by this channel? Great stuff and good old down to earth British ingenuity, done with good humour, great surroundings and a beautiful dog supervising it all.

Thanks guys just love your content.

LOTS OF GREAT KNOWLEDGE! thanks' FOR SHARING! Good show old bean!

Great videos guys. More tank parts please. Seeing how the machines work inside and how they are put together, cant get enough ;)

Another top video..keep them coming......can't wait to see the next installment to getting the engine running....

What a huge mess, but it looks like you guys got the solution, just got a put it into fruition. I have my complete confidence in you, and Jack.😊

Ref the "Merch". There has got to be a "I identify as a Foden" T shirt. I used al old Harley Davidson Piston as an ashtray for many years. They are ideal.

Awesome work guys

Was looking forward to this one!

Cool... keep the series coming!

Love the engine block as a coffee table, be a fantastic feature in a living room.

Amazed at the damage on the engine and how well it started and run

Plumbing pipe freeze kit , cheap, easy to come by and works a treat for shrinking things down. HTH

'When' you get an engine ready to run Joe, do you plan on wringing the oil out of your overalls to fill the sump? I think there'll be enough! It's the done thing to put the pistons in boiling water to let them expand, then the gudgeon pins will slide in. 🙂

It's been a minute since I heard Fatboy Slim. Keep up the good work.

1:53 "unfortunately I've got Jack(Goose) here to help me" ... cue the music.... priceless 😄. Loving the more 'in-depth' videos...keep up the good work 👍

Music in this episode is what I like. Seems you got good taste

Awesome video thanks lads very much appreciated top job top team 🇬🇧

This is a fascinating process! Excited to hear merch is coming, I would love a "well that's mint, innit?" design.

Amazing you guys have hearts like lions and such a positive can do attitude. Just like Honey Badgers Bring on the merchandise.

A detail I noticed that may or may not make a difference for the project. The crank looks like it is a built-up type with bolts running through the main and big-end bearing journals. Would taking the entire crank apart make the disassembly / assembly of the connecting rod big-ends any easier, or would it just make the work more complicated? Absolutely impressed that you and Jack just get stuck into things like this without any fear.

Can’t wait to hear the rebuilt engine run

This is great fun, glad I just found this channel.

Great Channel, enjoy watching. Once you have "carefully" installed the good pistons onto the small ends of the connecting rods (please use a c-clamp to not beat an air chisel on the conn rod)...call anyone in your area that works on air-cooled VW engines, ( or Google it) they will be using a "breakaway ring compressor"...it might be too small for your pistons, but you will be able to see how it works and fabricate your own tool in the size you need. Turning the engine with the cylinder surface straight up level, start the cylinder/liner assembly onto the studs, wrap your custom ring compressor around the 2 pistons which are "highest" to the liner and start them in... repeat the process for 2 pistons at a time while also lowering the cylinder assembly down. I rebuilt my sisters VW bus engine in the driveway with a ring compressor fabricated from a piece of flat spring steel 50 years ago.

Great video guys! Very interesting.

Great work guys...🇬🇧

Loving your work 👍🏼

All this goodness AND Fatboy Slim?!?!?!?! What more could you need? :D

Exited for the running result 🙏

Heat the pistons with a hot air gun, I’m worried you may have damaged the big end bearings by knocking the pins out, you have put a large side/ twisting load into the soft bearings that are not designed for a load in that direction. Great channel, love it, keep up the fascinating content 👍👍

nice work lads Jim

Great content as usual!

I think the heat method is the most likely. Remember the production of these tanks during the war was done in factories with the roof off and very basic equipment. Heat could be managed at all times of the year but cold probably only in winter. The factories were built up at the same time as the tanks as they were moved from areas of German incursion. Many were started up the crew doing up the last bolts and driven off to be armed and then onto the front line. That is dedication, desperation and a faith rarely seen elsewhere!

I must have to say, Mr Hewes, this channel's video and sound quality HAS improved enormously. Well done to your video Editor. Give that person a pay raise!

By the way, it was quite common to have aluminium blocks in the Gudgeon pins are to 475 hp Sunbeam engines we are rebuilding at the moment. I’m exactly the same system. Bit lighter than the Russian system though. Keep going you got a messy a job there. Have fun Michael

I think the holes in the crank webs are for big end pin removal/insertion. Keep up the good work.

great video chaps

Ted on hoody with an adjustment hammer in his chops

Great work , thanks for sharing 👍💨💨

Gotta love Jack! We all wanna be Jack!!

A legendary song for a legendary engine rebuild. Right here we have a broken motor and right now we will bring it back better then from the factory.

A great explanation of the engine love the crack to lots of banter but safe banter until the next video😊😅

Perfect just in time for a commute home.

Love the music choice right here, right now by Fatboy Slim

aah, brings back memories of my hire-car fixing days, except i swapped around old 70s cortina engine bits to get knackered 80s transits back on rent you have a goldmine of mechanical merch there...

Right here right now baby!!!

For the piston pins heat up the blody piston with a torch and the pin will be free . On most russian diesels it a interference fit when cold . for instance the YAMZ 236 238 SMD 62 D247 engines

looks like you're on top of it, looking forward to the next instalment. Sort out the roller door though in case it decides to suddenly come down on something expensive

Recently found your channel….brilliant. This is compulsive viewing for me. The inventive and creative approach to these mechanical challenges, all with good humour and antics is a true tonic. Many thanks.

thank you very much for good entertainment.👍🤗👍🇸🇯

I now it’s been said but quite rightly if u warm the pistons with a propane blow lamp don’t go mad around the piston skirt u will find it’s easy to remove and refit

Mains caps on engines are line bored with the block. which means no 2 caps are the same. So if you put the caps from another engine on a different block, the bore won't be round. 😖

Looking forward to the next video

Ace video keep them coming 👍

Would defo buy a piston head if they were up for sale, can't wait to see some stuff up! Keep up the work lads 👍

Please more on this engine build up please!!!😊

Good job 👍

I approve of this episodes music ❤

Yay! Merch!

that t-34 engine sudnt of run the state its in,just shows how tough they were tho,those engine parts will sell like hot cakes.ill be watching for them.excellent videos lads keep it going

those engine parts look so cool! such an odd way to go about doing things

The T34 pistons all polished up would make a good table ornament and talking point!

liquid nitrogen probably not easy to get a hold of but dry ice should be easy to source and well within the needs of your application...should be a lot more budget friendly as well. thanks for the vids

Very cool! Great video😊

I am looking forward to when the 'patient' receives the new heart and moves into the recovery room. All good surgeons check their method until they are sure of being able to do it, then they give it a go. The next video will be fascinating!!!

what a great vid.

Yep those pistin pins are the same as the R3350 , floating pins with magnesium plugs in the ends, agree, just kiss them with a blow torch and they will push out , Great work lads.

Re Merch, 'I identify as a Foden' Tee shirt has got to be in there!!

Brilliant !

The plant where they were built was huge . All closed down now but an impressive building that still has the gantry cranes overhead
