HOW TO FIX A T-72
HTML-код
- Опубликовано: 13 сен 2024
- Me and the team have a go at removing the broken starter motor and Engine oil priming pump form this T-72 Tank for repair.
Words can't describe just how much time and effort it took to remove these broken parts, this is not a vehicle that could be fixed quickly in the heat of battle not something I enjoyed working on. However I hope you enjoy the video and learn that designing something so compact is not always a great idea..

Yes, FLANGE.
the "cooling" system is there to pre-heat the pump in harsh cold conditions. The T-72 has a diesel heater that is pre-heating the coolant.
This kind of repair work is done by pulling the engine out as far as I remember. The whole work can be done under 6hours in field conditions (well 3.5 if you make those techies some legs).
I hope you have the M version, the maintenance of Oil filter is same PITA on the Classic, the access is from the turret via door, the M and newer has the filter up in engine bay on sides of the air filter box, if I right remember. Dont forget to hold the primer until you ignite the engine, if you start with air and not the electric starter (or was it the other way around?). Also never use fuel meter button if anything else then diesel is used, or kaboom. And now major safety advise, *always sound the horn just before you start the tank so everyone outside clears the tank surroundings. The hydraulic gearboxes can be in gear even if you are in "N" with gear selector, especially in cold weather, so the tank might jump a little when starting* .
Now the last advice, you CANNOT turn if you depress the clutch!
Also dont forget to clean the big airbox (plates are -cleaned- washed with diesel), if its too clogged in summer, it can caught fire due to booster suction (dont ask me how I know).
Great info "M"... I would like to know how you know ;-). I'm getting ready to remove the back deck of what looks like an identical T-72.... at a Tank Museum in Canada. Our Oil priming pump and starter/generator work fine. But you see the oil pump doesn't, and it's at the bottom of the engine we now need to remove. Great video Hewes n crew... can't wait to see more. ps.... we should chat!!!
pps.... when you go to remove the air compressor, make sure the tracks or road wheels are "Blocked" in case you disconnect some "Brake" linkages that are in the way. ciao
@@user-md3im1ex2s I served in mid 90s as T-72 tank commander/plt. commander, but mostly as instructor for new drivers and commanders. While I did teach the technical preparation for drivers I didnt do the service personally. As mentioned we had specialized detachments to do so.
I forgot a lot of details already, back then I had a very nice large book with everything.
After I saw this video I went trough my old stuff and found a textbook for drivers but its the Part1 only. But still there might be some pictures or data interesting to you. It is written in Czech language, nothing a Google translate cant master. It is not a service manual, more of a everyday maintenance manual, but there are pictures that might help identify parts of the systems and where to look after them.
@@user-md3im1ex2s oh, and btw the mechanical oil pump is on the bottom of the engine, I dont think it can be removed without pulling the engine. Do not forget to drain the oil from both oil tanks (main oil tank, sub tank) and the engine oil pan.
Are you sure the mechanical oil pump is not working? Maybe its the oil pressure sensor?
@@madigorfkgoogle9349 Very cool. I do have driver and tech manuals... and I'm familiar with google translate now. A vehicle technician would be worth their weight in beer.... Canadian beer!
I was a GM tech for several years, I feel your pain, We could pull the entire pack, transmission, and engine on the M60A1 in less than 2 hours. And it was air-cooled. What a mess, well-done fellas.

A long time ago, a very clever man ( my father) said to me, while I was trying to fix my Ford Capri, " If the B'stard who designed it had to work on it, he would not have bothered" I find this very true of many things in today's life.
Having "done stuff" to the ford capri I think its infinitely easier than todays vehicles which I think are designed to difficult on purpose.
@@siypic They are designed to be serviced by trained professionals. The amount of complex 21st Century stuff that is attached to a 19th Century idea is legion.
Your regular amateur is not meant to be able to fix it.
@siypic I miss the simplicity of my old capri, just about everything on it could be fixed , parked right outside my house
@@I_Don_t_want_a_handle They make it a pain in the ass even for the guys trained to work on the stuff. That way you either pay out the ass to get it repaired or you just throw your hands up and get some new bullshit which will do the same thing to you in 3 years. Win win for the manufacturer.
I always feel that way when working on a Ford, but a lot of vehicles now are such an ass to work on. Some still are thoughtfully designed though. I dont think any Fords are, in the last 20 years
One of the laws of Murphy is that a job will always grow in proportion to the size of the problem, the smaller the problem the larger the job will get. You have very aptly proved that law.
Isnt that grow in inverse proportion ?
Murphy was a genius !😂
According to mr o`tool Murphy was an optimist.
@@uncle_moose correct
So that's where Toyota got the idea to put a starter motor deep in the guts of their V8 diesel engine, 79 series etc. Brilliant!
Then Ford took the idea even farther, they put the water pump inside the engine. It is turned by the timing chain. When the water pump fails, all of the coolant goes into the crankcase. How do I know this? Duh…. The V6 engine in the Ford Flex has this design. Only $2,200 to repair it. If you catch it when it happens, you can get get away with pump, timing chain, chain tensioners, gaskets, oil, coolant, and a lot of labor. Other than this one flaw (major), it is a great engine, four valves per cylinder, double overhead cams, and I get 23 miles per gallon at 75 mph in a car that seats seven.
Donkeys years ago, Isuzu sold engines to Vauxhall to put in their Astra cars. Decent enough units, but the alternator was really low down and tended to get splashed, which progressively degraded the rectifier diodes.
I owned one such vehicle, and was a regular customer of Aaron Auto Electric in Leeds, for yet another reconditioned alternator.
Most modern cars are built like this, so that repair is expensive and problems can't be easily fixed by the owner.
What do you mean by repair? No, please go see the sales department for a new vehicle.
@@Wyrm1701 .. lol If that was the 1.7 turbo Diesel , on mine the cam cover leaked .. straight into the Alternator , by some miracle a can of brake cleaner was enough to revive the alternator
Master Milo made do with dive bottles of air to start his T69 until he got the electric start functioning. That meant he had to get a dive compressor to fill the tanks. Interesting to compare the cost of that to using argon. He did that for a while but if it's hard to start a bottle disappeared real quick. Great to watch you working from 1000s of km away and not get dirty. Cheers.
If you don't want to buy a dive compressor you can take your bottles to the local firestation in the Netherlands and they will fill them for a case of beer.
T..69?

Yes. I was thinking of dive cylinders rather than welding gas. If it's only an occasional start with a duff compressor in the tank then welding gas isn't too painful and it's inert, but if this is a common thing then a couple of dive cylinders would be MUCH cheaper to refill at a dive shop. The cylinders would have to be in test for visual and hydraulic otherwise the shop wouldn't refill them. It's also likely that the starting system in the tank isn't anywhere as high as as for diving. Most air compressors only fill to ~10bar, but diving system work up to either 232 or 300 bar so a first stage regulator, (which lowers to ~10bar) would be needed. Better still, spend the money to get the compressor fitted in the tank. The other option is air weapon charging. This is typically the same technology etc as used for SCUBA diving. Will post this to Mr H in another post.
Don't worry about the tank designer- Brezhnev had him shot a long time ago.

I was subconsciously hoping this to be true but it looks like he died in 2013

You know guys I think I might know where you can find just about any parts you need ( cheap) . Problem is they more than likely will have some “ heat stress “ damage, and you could get shot at,or blown up.😮
that prime pump probably is not water cooled, it is designed to be water warmed, because in -40C it would do no good if it just spun some jelly around without being able to generate any pressure
It wouldnt make any sense to heat up oil through the pump, because the surface area inside of it is so small. It would make more sense to just heat the oil reservoir and after priming for few seconds, you have warm oil in the pump anyway. But I guess it would be technically possible, I cannot think of any good reason why an oil pump would need cooling, heating or if it was dual pump head for water and oil, why would you need to pump water with an oil priming pump.
@@Catrik when everything is -40, you heat the oil tank but there is no circulation because it is like a jelly everywhere else, hence they design these things to be warmed up via cooling circuit, and cooling circuit goes everywhere where oil goes
pumps for liquid oil don't work with grease viscosity oil
But if the tank is cold what do you use to heat the oil ?
@@ianc7866probably has a diesel powered pre heater and aux coolant pump or just light a fire under the thing and wait a while.
@@twaymouth exactly, something like aux diesel heaters for cars and busses, just for heating up coolant, or, keeping it from freezing

Wow, what a complete nightmare of a job. Kudos for sticking at it. Re compressed air, you can re-purpose old gas bottles & fill with compressed air. either that or an old oxy bottle. Thanks for uploading.
Everyone of us who has had similar issues with a poorly designed item and usually its ridiculous location, feel for you right now. Just think once repaired you have to get them to go back in 😞

At -20 c, you want to preheat the engine by heating the cooling system and circulating at around the engine block. Russian trucks run 80 octane benzine because diesel is a mother fcuker to start at -20.
To show my support for you during a frustrating task I went and threw some spanners around the garage whilst swearing loudly
With hindsight I should have moved the car first 😐
Nice work guys 👍
A good way to start my day, watching you all practice yoga/ contortions geting coverd in shmoo and coffee knowing my job today in just packing clean stuff. I Thought I would miss working on stuff turns out I much prefer watching you all working on it 😂
The air compressor on our T72 also didn’t compress. We pulled it out (pretty easy, for a change), and it was knackered. It’s driven by transfer case so it runs continuously, with an automatic valve loading and unloading it. Unloader valve setting is pretty high (2200 psi, I think) so as compressor wears, it can’t reach unload setpoint, and ends up running continuously loaded. So then it wears out quickly.
Tried lapping the compressor valves which helped a bit, but rings were worn. (Found a aircraft supply company that still makes them, but part number is slightly different.)
We installed a used one that generates 1600 psi, after lapping valves. What we need to do now is reduce unloader valve setting to just above pressure it takes to crank engine quickly (about 800 psi) to minimize time compressor spends running loaded.
Like Adam suggested, coolant to priming pump (and a lot of other things) is to heat up oil on -40C day.
Starter is 48 volt so 4 good batteries helps start. There’s a complicated series of heavy relays to left of driver that connect all 4 batteries in series.
The starter has quit on ours too. Spins but no engagement. I suspect planetary gear set has broken up, but it could be hydraulic circuit that drives dog gear into engagement.
There’s only a coarse strainer on tank suction to main oil pump and priming pump. We had a ton of sludge in the bottom of the tank. Access is quite easy to pull suction hoses and drain and flush tank.
We checked priming pump discharge pressure after flush and only got 1 bar. Supposed to be 2 bar. I suspect sludge has worn out pump.
And now latest problem is the drive shaft from the gear train to main oil pump has broken, and some shaft bushes in pump casing are all chewed up. I suspect sludge in tank also caused this. Easy to remove cover from underneath to get at shaft and gears but not easy to remove pump.
Anyway, great video! Thanks.
Great to read from people who know what they are talking about. I love T-72s and love working on them, unfortunately they are getting phased out in my country.
@@oliverpasztor788 Did/do you normally simply remove the entire engine (and maybe transmission if connected?) out to be able to "easily" work on components like the various oil pumps they were fighting in this video?
@@bobvines00 it is usually easier to do so in a workshop environment, because you have the necessary infrastructure and it's more convenient. It's a 4 hour job to remove the engine, but it's rare, because these components rarely go wrong. These tanks if properly maintained are very reliable, however our tanks unfortunately were neglected due to lack will, spare parts and proper Russian lubricants, so they regularly break down. For example the original engine oil has the consistency of honey, but it's not available in the West so we substitute it with a German oil designed for tanks, but it's not ideal and it shortens the lifespan of the parts.
@@bobvines00 That’s the plan now. The main oil pump is accessible from underneath, but to remove it, you have to first remove one of the suspension bars. I’ve done that job on an M60 and I figure it’s easier to pull the engine!
Pull it, twist it! which way, that way, what way, that way! greatest team work ever!
Some Russian Army Mechanic is watching this and thinking, "Wow", thats how you get that out....

@@konstantin88181 definitely this! A former teacher of mine worked on these thing for 30 years. You dreaded the moment you had to shake hands with him. He had the grip strength of a vice.

Quite the opposite, he probably thinks these guys are idiots
You guys can say what you want, in the beginning I had thoughts once about some of the comments they made about Anerica in general. And had an exchainge with them..

Top job boys.
Dear Joe,
Digging into a Russian T-72 battle tank is a hell of a job. The Russians still aren’t building tanks with a so called cassette engine what easy ca be lifted out of a tank for maintenance and easy to be replaced.Th Russians still use the old style engine mounting system what makes certain parts very hard to reach and to replace. Since the Russian army has a huge number of soldiers in service including soldiers who are specialized in maintaining their tanks nobody cares about the number of hours they need for maintaining these tanks. Even the most modern T-14 Armata still has the old school engine mounting.
Hopefully you’ll get the T-72 running soon. I look forward to your next vlog and send you love from the Netherlands
Good thing then that the T-72 was not designed by Russia, but by the Soviet Union.
@@thodkats Wrong……these were designed and produced in Russia on behalf of the Soviet Union. These were used in most of the Warsaw Pact countries. Both bodies no longer exist, so it is completely legitimate to talk about Russia when it comes to the production of these tanks
But this piece, was made in Czechoslovakia I think.
@@jansindelar606 they had to use the russian blueprints with minor modifications, and usually a few USSR officers were assigned to these factories
That may be because they are using the same damn engine out of the BT-7M tank from 1938 (with a couple of updates), instead of designing a new one from the ground up (apart from the Ukrainian designed T-6 of course) ...... and no the T-14 wankpuffin doesn't count as that one doesn't work
Yet again, your persistence and ingenuity win through and the parts are extracted. Fixing and replacing them will be a doddle!!
This is like changing the light bulb on a Renault Megane only with Armour
Keep positive😊
What an absolute nightmare! Top work as always lads! 💪
"So we basically looked at a few manuals and... er... we got quite bored. "
I can only assume the Russians banked on most of their tanks getting blown up before they needed any maintenance. What a total PITA.
Brilliant. Another winner Ted n Co. production!
Well when they didnt move they could act as static guns.
no , the Russians can maintain their tanks , any trained mechanic can work and maintain a Russian tank ,and they are generally more reliable then western tanks , Ask the Syrians ,the T72 is now working for 14 years straight , its not a turbine engine that can blow up if a spec of dust gets in , its not a multifuel engine that cant run reliably on any fuel ,its not a complex piece of engineering like the leo 2 that its own complexity is its main downfall in ukrain , its a crude workhorse that you can actually maintain on the field without having to send it back to the manufacturer ,and it still does the job , regardless ,if you get hit by the main gun of T72 your having a bad day regardless of what tank your sitting in
I just want to say thank you to you guys for the pleasure your videos give me. Its so nice to watch you grovel around in the mud and old oil, get bent out of shape trying to reach the impossible and worry about whether the damn thing will ever work again. Its so nice because I will never again have to do it my self.
Makes the Chieftain look even better! Great video boys as always.
The Chieftain was a great tank. People piss on it because it is British.
@@I_Don_t_want_a_handle Mostly because of that multi-fuel engine, I think. Jordan has a load of up-engined ones with a sensible diesel in, & arguably Chally 1 is basically a re-engined chieftain at heart...
trouble with a cheify is you could hear it coming from miles away it was so fekkin loud.
i was on my basic military service tank driver right on this type. Reparing motor oil pump was my first job,when i have assigned machine. Motor oil pump for engine is on diferent places and it is possible take it out during service hole under engine.it is little bit more forward and left,it is not easy take it out,but it is work for some hours. Basic problem with oil pump for engine is leaking oil inside to pump during sealing behind working parts of pump and electric part of pump. if you dont have this in working condition,starting is dificult and you little bit destroy the engine bearing,because its DRY starting.
It looks like he'll and it also looks like fun to learn about war machines like this. I'm not gonna lie I sorta envy you guys for this
I do admire the enthusiastic approach you guys have on getting a job done well done
Could be a comedy
Patients of saints
The oil pump bit.
Excellent content.
They criticize a lot, but in combat, not in a garage, the Ukrainians prefer Russian tanks since they can repair them 10 km from the front, in the middle of the field, on the other hand, leopard Bradley's, challegers have to be removed from the front to the rear and in some cases to Poland due to the complicated and expensive repairs, in the end they dismantled the fan by mistake, it was not necessary, to remove the oil pump. In short, they criticized because they did not know how to do things,
One more push madam! Congratulations you have a ten pound baby oil priming pump!
In battle at the time these were designed they rushed forward in a change and some got through! The British cavalry units tried the same thing but quickly ran out of machines and crews. The Russians did not have the same restraint and made more tanks and crewed them! Say what you will the crews were brave buggers!
thanks man ive been trying t get my t-72 up and working and this fixed the problem

At 14:36 I couldn't help shouting out "it's a boy!"
48 hours of Soviet hell later, and the b'stard still doesn't work. I honestly never thought it would, to be honest..
It does explain why Russia kept multiple tank parks full of unloved tanks. Not that they have many left these days. It also makes me think that Ukrainian tank engineering must be exceptional considering their ability to repair the buggers. 😊❤❤❤😊
😂I enjoyed this video while having lunch. Looks very familiar to me. I would have removed the radiator too, it will give much more space and use some pieces of foam rubber to sit on while working.
Definitely my least favourite vehicle to work on 🤣
@@MrHewes This is probably a dumb question from the unknowing Internet, but would it have been easier & faster to remove the entire engine/transmission (if they're attached) so that you could access stuff like the priming oil pump & the alternator-xxx combo? My guess that's what every military does that has tank repair units. (I haven't been there or done that, so these are just my best guesses.)
Edit: Great video, even if was a big PITA for you guys! Definite thumbs up!
Times like these I’m glad I’m on this side of the camera and not your side
Always tomorrow mr hewes 👍👍🇦🇺
Lol it was like watching the birth of a baby complete w “womb” waters 🤣🤣🤣. It’s now Dr. Hewes!
It's almost as if it was designed with an expectation it wouldn't survive long enough for the starter motor to fail.
Exactly what I was thinking
Also hence why they built thousands of them.
The T72 wasnt designed to be repaired, it was mass produced if it died they would just replace the whole tank, they had thousands of these unlike the UK where every tank counts.
My thoughts as well.
they had 1000s though they dont have many anymore
no, you are wrong, it was repaired and even maintained (tank is not a car), there were company and even battalion sized repair units
great video again chaps ... always enjoy watching your footage from these mad tank repairs...

Russians end up getting on record of repairing their T-72's, T-80's within hours. even though its by haste because the vehicles are important, i think it was 26 minutes that it took them to rip a whole transmission and Engine out, half an hour or so to repair the damages and 14 minutes to put the whole damn thing back in before it fully was able to drive again
other than that the T-72 is such a fucking bueaty, even though it's a cramped small death cage of its own everything about just seems so cheap, difficult yet wonderful
its really about using the minimum amount of resources ,while maximizing the amount of use you get from those resources !! either way ,if you get hit by the main gun of the T72 , your having a bad day , regardless of what tank your in

The clear tube on your Milwaukee torch needs a clean, haha. I have the same one. They're brilliant
The coolant around the pump is for heating it in the winter.
Russian winter are ridiculously cold and they can heat the coolant and circulate it around the engine and oil pump so that before starting the engine all the oil is not frozen solid and can circulate through the engine.
Like a kind of heat exchanger idea.
These systems are commonly used around arctic areas.
I was about say this!
You boys have patience of saints
I think the Russian mindset on this and other tanks is that they have a life expectancy of 2 weeks (or 5 days in Ukraine) so if it breaks down, get out and get another becasue they are as cheap as chips for them to build new.
Not a bad philosphy in a battleground as the Allies proved with the Shermans. While they could be replaced almost the next day the Germans struggled to replace the Panzers and Tigers and numbers will always win.
But props to you two for keeping on keeping on. 👌👏
The Sherman was designed to be easily maintained, you could change the transmission and final drives without dissasembing the rest of the tank!
@@idrisddraig2 I never said it wasn't. My point was that it was the sheer numbers available that created combat advantages over the less available German tanks.
I hear the turret pops of easily though!
You do pick them don't you Joe! At least you had a happy delivery of a very slippery oil pump. Good catch bye the way. As usual, up to the very high standard you set! Thanks.
Please, please use copper grease on every bolt and thread when you rebuild it! makes it sooo much easier the next time.
Anti-Seize. I've never thought to call it copper grease. Goes to show no matter where you go, there will always be a new name for a tool or item You've never heard of.
You need a rock climbing harness and the engine lifter that goes on the forklift then hang upside-down to get this job done
When you are reinstalling the fan don't forget to measure the fan slippage torque. There should be a tool to measure in the kit on the tank, if it came with it. If it's not properly adjusted it could cause damage in the long run.
2:48 _"....need to use an adjustable hammer.."_ 😆
Imagine doing that job in -20 conditions in a blizzard, twood be bloody awful probably impossible.
Well done fellas.
How about doing that in those conditions while being shot at? I can't imagine what that would be like, *if* it ever happened instead of repair units towing the tank to a field repair unit (once it's "safe" to recover the tank) with the equipment & experience they need.
What a nightmare! all I kept thinking was how much of a struggle to get it all back 😮
I was literally watching one of your videos like 5 mins ago, and the t72 was in it so I was wondering like "hmm, haven't seen a video about that thing in a while, I wonder when they're gonna do some stuff to it". then 5 mins later I see this video in my feed, posted "2 minutes ago". quite silly
I admire you patience and determination.... but at times like that, perhaps taking up knitting is more rewarding pastime!
So when I'm thinking how sh$t life is, I can rest assured it could be worse, I could be a Russian tank mechanic
As painful as this video was for you to produce, I will say it was very enjoyable to watch. Looking forward to the next installment of T-72 madness, even if you're not, LOL.
i've just changed the 2 pollen filters on a vauxhall/pugeot half-breed, it's above the clutch pedal, i would gladly swap...
What a beautifully built main battle tank with incredibly easy and accessible parts. Disposable tank for sure
The german work overalls does his best
Good perseverance with that thing...Looks like a real challenge. Thanks for uploading..
T-72 is much much easier to mentain and produce than all tanks from 1960-1985
Argoshield is an inert gas.
Can you start an engine on an inert gas??? Would compressed air not be better? It has O2 in it, which promotes combustion?? What do you think?? Perhaps a scuba dive cylinder would be better??
Top video, thanks for posting. How on earth do you know how to work on these machines, I wouldn't know where to start? John (Sydney, Australia)
I don’t. I just figure it out
Maybe keeping the starter oil pump warm in -40c and priming the warmer oil and out of the way of blast damage is more important than accessibility.
I wonder if the oil primer pump is more water heated, rather than water cooled, to try and keep the oil thinner.
Although I wonder how that works on a cold start.
Generally - for their flaws, nations tend to have reasons for designing things like that in the way they do. Even if it isn't immediately apparent to people looking at it 50 years later as a curio. Although even in military usage, I'm sure the crews involved in keeping them running curse in very colourful Russian/Ukrainian/African etc when they need to fix anything on them. But then, it's probably all they know having never experienced Western style armoured vehicles where maintenance times were more critically thought of during their designs.
You need a medal for working on these mate
Bloody well done gents, this would have to be the most heart-breaking, soul destroying mechanical job that I've ever seen!
As you said there are two MZN-2 electric oil pumps, however if you swap what you called the "tow start pump" with the engine oil priming pump you won't be able to start the engine elictrically because that pump engages the clutch that couples the starter motour with the intermediate gear when pressing the start button.
I bet the Russian crews just cut a hole in the bottom of the tank and welded it back up again 🤔
I think your first T-72 mechanic to wear blue gloves
Could watch you lot for hrs love this channel keep them coming lads
This is why Russia needs twice as many Tanks as anyone else.
To think that we worried about these things coming through the Fulda Gap? They would have trouble even starting the engine!
Lordy, hours of "fun", at least it keeps Adam out of trouble. "Nobody's going to ever get at it so we may as well plumb it into the cooling system as well." It might make sense if the T72 has a preheater like Master Milo's type 69, having experienced a frozen fuel system (at not very much below freezing if you please) I could appreciate that.
This might seem like a really stupid question, but why did the manufacturers make it so difficult to maintain?
Most likely maintainance wasn't in the equation. Everything else was sacrificed for making the tank as low and as small as possible.
I wonder if the theory was..just build another one.
When labour is cheap but parts are expensive, it makes sense to focus on cost, production, and reducing number of parts needed for logistics, especially if it helps keep the tank compact (which was a strict requirement at the time).
Great way to start the day. Thank you Sir.
Я не знаю, что вы там читали (скорее всего, ничего), но вода в маслозакачивающий насос МЗН подаётся для подогрева масла (не забывайте, где был создан этот танк, для эксплуатации в какой климатической зоне). И меняется этот насос гораздо проще, чем показано у вас. Половину танка разбирать не нужно.
and there i was wondering if it would help if you unscrewed the front light lenses - hehe !!!
amazing work as ever Joe and team, when your an olden man dribbling in your beer, cider, you'll look back and laugh, saying do you remember that damn T-72 starter motor and oil pump?
The one good thing about American tanks is they made them so they can be taken completely out and modular iirc. So u have a little room to work. That looks like a nightmare to work on. Plus u have think steel plate in the way. With a car atleast u can take off the panels if u had to. Much credit to trying to fix that
My heart went out to you when you said you would rather change the clutch on a 2CV.
Thanks, I needed this
Numbers gentleman , numbers . It’s a matter of attrition . To be fair the T72 does it’s job and if serviced and maintained as it should be is a reliable tank . Russian way of thinking and western way of thinking are totally different . I like a Soviet era tank
thanks bro, I had the same problem on my t72, now I can go to the market.
I have been rebuilding the front suspension on a Jaguar XKR this is much worse ! Thank you for your efforts ❤
Meanwhile in Russia many tank engineers are laughing saying
my chuvstvuyem tvoyu bol', tovarishch 😂😂😂😂😂😂
And I thought replacing the engine in my 05 Mazda tribute was a bitch! You good fellas have totally made my job look easy😮 fortunately, Ted was there to guide you😊
Maybe wetsuits could be a good shout for that sort of job.🤔. Keep up the great work lads. Met you at tank fest 2024 .thx .
