Tank track disassembly (Type 69-II tank)


Hey folks, great you’re watching again! We’re busy restoring our tank We’re going to disassemble the tracks today This isn’t an easy job, they’re seized Everybody saw that when we pulled it off the trailer It’s was crackling on all sides We’ve noticed something here.. There Some of those pins are broken Because they wouldn’t turn They went like this.. Crack, broken I don’t think they will come out easy How does such a track work? Overhere.. This is the only wheel which is powered This gearwheel catches in those links of the track it rotates it like a chain If we move forward, we see these giant wheels Those are the roadwheels It’s standing on those. These wheels have suspension The front wheel is a tension wheel It has a mechanism to move it forward and backward That way you can control the tension on the track The track itself doesn’t want to rotate anymore That’s because.. see all these links Those are kept together by pins it works as a hinge But those pins are seized up Some of those even snapped and as you can see overhere.. it’s crumpled together like a harmonica The tracks should rest on top of those wheels.. It doesn’t do that I think it will be a challenge to take it apart Let’s start with loosing as much tension as possible With the bolt you see overthere.. We can set it loose and rotate the nut it’s attached to a wormgear it rotates an arm and that’s how the tension is adjusted Lock bolt is set loose We got this wrench to adjust the tension That won’t work Doesn’t fit.. We need a bigger wrench Let’s make it! Tube isn’t strong enough Big ass mother f*cker wrench and it works Tension is released! it’s going down Overhere it’s resting on the wheels A lot of tension has been released, look overhere We can adjust it more, but it won’t do anything We have clearance here I think we should try to get a pin out That’s the one Especially with that WD40.. it must come out now It’s not moving yet Let’s try with the fire wrench it’s stuck on one side in one link Our pin is worn.. This isn’t strong.. such a tiny pin Exorcist pin! No movement.. This pin doesn’t feel like it.. This isn’t working.. not with the hammer I think we need a press Wait a minute, we have a press Look here! Why haven’t I seen this before? This is an official track press This is the way.. but our frame isn’t strong enough I think we need a serious press I think Holmatro can help with that Let’s go! Good morning! Nice material! Cute! His small brother! Goodmorning – Goodmorning How are you? Fine, how’re you? Nice! You need something for your tank? Indeed, we have an issue Yeah? Hinge pins which won’t come out Nice, we have something for it! That’s what I thought! I have a 50 tons jack and a pump and a hose And if that won’t work.. You can throw that tank away Let’s take a look This will be pressing! 50 tons Well, bang! Even that tank can’t stand that This can lift that whole tank awesome hey? We should put it right in the middle Good, success! Great, thanks! 50 tons Now we can see what we’re doing Nice, ey? Look at that Exact the shape of the track links This is where the jack goes This supports the track The pin is forced out through that hole At least.. we hope so We have 100 bar What’s the load? That’s.. 7 ton? I say; more 150 I think it’s getting tricky If a part breaks or is ejected.. We’re not in a safe spot We should find a place which is safer We have a tank by accident That’s armoured Let’s sit in there I hear something The pressure isn’t increasing, something is moving Now the pressure is rising again 300 bar I can drop the pressure to 100 bar so we can take a look to see what happened Our pin is buckling I think we need to shorten that and apply more force A shorter pin! Let’s pressure it! 150 360 25 tons But we don’t have a 50 tons jack for noting I heard something That can be good That’s possible, let’s peek More, more It did something I heard something More sounds Pressure is dropping Pressure is dropping fast There’s something really broken now or… Yeah.. at least something happened I will drop the pressure to 100 bar then it’s safe and it won’t fall apart Let’s see what was moving We could keep pumping and the pressure wasn’t rising That’s a sign something is moving I don’t know what was moving.. not our pin for sure it’s in the same place What we can see; Our pin is yielded Our heavy support tube is deformed as well That’s because the load is of center That’s because of this part.. is bend Take a look; It looks like a piece of bubblegum That was it.. that was the bang we heard Of which we hoped it was the pin moving Not.. We had 400 bar.. let’s calculate 28 tons 28,5 tons was on it almost 30.. But we have a 50 tons jack I think we need to build a heavier frame and try again! Extra heavy rib a solid piece I have a new pin let’s harden it I’m going to heat it and quench it Then it will harden I hope it won’t look like a gnawed bubblegum afterward it should be hardened now If you heat steel like this The crystals are regrouping they’re getting loose from the crystal structure if leave it cooling down they’ll have the time to find their places in the structure the material isn’t hardened If you heat it so the crystals get out of their structure and if you quench it in cold water or oil Those crystals won’t have the time to find their place You’ll get a lot of stress in the material that makes it harder so this one should be harder It should need some tempering now You’ll heat it a bit, so those crystals can regroup a bit We’re not going to do that, it must be really hard It’s finished! Look at this! Our super track press XXL 2000 Bang! So, vlogger move with it! This one is really strong, look at this This is a solid piece of metal That’s extra crude This one, extra heavy H-beam Overhere; extra ribs out of bulb flat and here as well that side was strong enough already but it’s even stronger now! and now.. those pins will fly out bang! Here we go 360.. that’s 25 tons 500 bar almost 35 tons of force pressing on there Something happened That sounded more like our frame Should we look? A bit of the same issue as with the former pin but with more force this time Our frame is strong enough Our pin is not hard enough.. We could get a tougher pin but we applied a lot of force on there We did a discovery We’ve sprayed this entire track with WD40 and see what we found Believe it or not.. This pin is loose but we have another issue now the pin must go out on that side we can cut the head.. but we have a lot broken pins already we would like to safe that pin to get it out.. there’s a tank in the way we’re going to jack it up and see if we can turn the track to get this pin in front or at the back depending on what side is the easiest and then we take that pin out and take that track off! get off you! It can get out! we hope.. Let’s try it Take it! You nasty track! Who’s your daddy now? Look! It’s rolling Look overhere Because we were doing such a nice job we quickly took off the other side as well Quickly… Working our asses off… this side was even harder than that side It’s all bare now we need to make new fenders sandblasting paint it Do you have a company which can do the sandblasting and can you sandblast this tank and put primer on it give us a sign we’ll bring this thing to your place and we hope to get it back painted that would be a good deal we can proceed nice.. we’ll do that next time.. I hope so.. at least.. we’ll work on that for the near future So I would say; subscribe so you stay updated Hey folks, thanks for watching and see you next time
