[@madigorfkgoogle9349]

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!!!

@@NigelLawrence-e8f 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.

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!

[@steveburger2669]

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.

[@Wyrm1701]

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.

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.

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.

[@johnschneider3082]

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.😮

[@dsfs17987]

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

[@Catrik]

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.

[@dsfs17987]

@@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

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.

[@bigold81electra]

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.

[@bobvines00]

@@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?

[@oliverpasztor788]

@@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.

[@bigold81electra]

@@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!

The coolant around the pump is for heating it in the winter.

@@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. Another oldtimer one of the mechanics at my unit could tighten a bolt with his bare hands such that any mortal would need a wrench to break it lose.

[@rajaydon1893]

Quite the opposite, he probably thinks these guys are idiots

[@dbenci2071]

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.. I for one dont think they are weak, stupid or what ever negative you may come up with, I see them doing a thing that that many wish we could do as well.

[@konstantin88181]

@@dbenci2071 no offence to them, everyone want to talk nonsense and be famous 😜 also Russian army mechanics 100% don't watch their show, they already know everything about their and your machines.

Great way to start the day. Thank you Sir.

T-72 is much much easier to mentain and produce than all tanks from 1960-1985

[@mikebenoit6648]

Is there a way to make the whole back of the engine compartment open to get to the engine easier

[@alanglen5902]

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??

[@paulday-lh5mx]

Omg guys, your inside, cold, greasy and again wet. No doubt a few choice curse words were tossed about. I know I would of had lots of choice words. However it was a great video today. Thanks for taking the time to video while trying to work on that POS.

[@sundance2005]

If the oil prime pump needs to prime the engine oil before you start it and it's bad ...have they been starting the engine without priming the oil, what has that done to the engine? Good luck.

[@oBseSsIoNPC]

I do have the sneaky suspicion that the guys who invented and build these machines work with a priority list and battle in mind. You wouldn't pull wrenches when under fire, so there is no point to making all repairs simple. If you have problems with a tank in the field, they allow you to only fix the most important stuff somewhat easily. The rest is designed to be worked on after you strip the entire engine and transmission module out. Agriculture does it too in some ways. Changing a filter is easy, anything more serious and you might as well strip the machine down and repair everything at the same time, while the guts are on the floor. Things are water "cooled" to either help with the fact that it's all cramped up in there or to preheat in cold weather.

Lol it was like watching the birth of a baby complete w “womb” waters 🤣🤣🤣. It’s now Dr. Hewes!

[@stephengunrunnerhanson3550]

The things that break are always the hardest to get out and apart but your team are good at fixing the unfixable and I like watching you and your lads fixing and driving that when you leave the army never ever go back to working on any more then a push bike untill the next video

[@EngineeringVignettes]

Looks like the same oil pump unit that Aus Armour had a go at recently. As I recall theirs was full of rust. Hope you remembered how it all goes back together... may the force be with you.

[@davea8060]

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 .

Watching this process reminds me of this old adage, "better you then me" Indeed you endeavored to persevere.

[@marko4480]

when you got it did you start it without priming the oil ?

[@peteb5343]

Meanwhile in Russia many tank engineers are laughing saying my chuvstvuyem tvoyu bol', tovarishch 😂😂😂😂😂😂

[@aidansharp9483]

What do you do with your tanks once you have repaired them?

[@moisesaguila1875]

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,

i've just changed the 2 pollen filters on a vauxhall/pugeot half-breed, it's above the clutch pedal, i would gladly swap...

Thanks, I needed this

[@shed66215]

Even without the starter motor and oil priming pump it's still in better condition than most of the T72s that aren't in Russia at the moment - I mean it still has a turret on it, though getting to a point where it could be 'used' might be an issue. Stirling work by Ted's krew.

[@RupertBear412]

any idea how much longer it would it have taken to remove the engine for access? even if longer you may have had to remove less

[@steveearwig]

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.

[@oliverpasztor788]

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.
