Pullers, Gears and a Gas Axe

    For the last two days I've been hard at work disassembling 6 clutch packs from out of A ZF industrial Transmission. The work has consisted of pulling off bearings, gears, right down to the clutch plates and actuating pistons. Everything is labelled and the bearing numbers are recorded for ordering. The transmission is power shift with on the go automatic as default. The reason I've taken this out of the machine is to replace the Torque convertor which carked it. So while it's out I'm replacing the bearings and seals.

    I took my camera to work today and here's some pictures for your viewing pleasure. Trusty little GF1 and the 20mm. (you can't deny that a filter is a good piece of equipment- scroll down to see why)

    The cage is just about to fall.

    Nice set :smile: I like especially that cowboy hat, even though I would be worried that it will catch on fire :wink:

    So I have to ask, is a gas axe what we would call a cutting torch? Between the queens English and Aussie colloquialisms I seem to be scratching my head sometimes. Great shots by the way.

    Thanks all. Your favourite is mine too. I had the camera in burst mode and held it in one hand as I was cutting with the other. A little awkward. When I finished and went through the pictures I was really impressed.

    haha, I can be a bit tricky. It has a few names, the other most used being 'oxy torch'

    Thanks for the interest.

    Yeah, that's just a cutting torch.
    I was hoping for something exotic when I read 'Gas Axe', oh well.

    My favourite is Number 2, just lit. Good silver, gold and blue in the colours.

    So what are the little holes for? You can see them in the smooth sections next to the gear.

    Brady, those pictures are absolutely ace, nice one.

    Hey Hikari, good question.What you are looking at there is the clutch housing. This is where the plates are sandwiched inside. The plates are alternately placed in a steel disc, fibre disk sequence. In this clutch pack there are 21 all up. How it works is when a particular gear is selected it actuates a solenoid which then controls oil flow in through the centre of the main shaft and pushes out a piston squashing the plates together. The squashing together of the plates then causes the whole unit to turn as one and there you have that particular gear ratio. You will clearly see the internal teeth where the fibre plates lock in. The steel plates have internal teeth and lock into another part with the gear on the end.

    So to come back to your original question about the holes. When the gear ratio isn't needed any more ( this is an auto as well) so when the Dumptruck gets upto a certain ground speed the computer will shut off that solenoid and activate another one. The piston has a massive spring behind it so it is pushed back as soon as oil pressure is lost. And the plates are now free to rotate. So the holes let oil back in between the plates and keep them lubricated, but the main reason is when the plates are pushed together the oil has somewhere to go. If the oil can't get out the plates wont grip properly and that's how they burn out and get hot spots.

    I hope this is understandable:)

    Hi Brady,

    Another great series from you. I really enjoyed this set, I think it's even better than your cotton set, which was very very good.

    You'd better be careful, we're beginning to expect this quality from you every time......

    Great series Brady....

    Brand new hot off the press for you guys! Yesterday I stripped down a transmission from out of a CAT Challenger Track Tractor. Turned out pretty good, proud of myself actually!

    Thought you guys might enjoy to see it. Trusty old GF1 with the legendary lens.

    I named it 'Like Trees in a Forest'

    Glad you posted again on this thread...I didn't get a chance to see it first time around. Interesting set.

  16. Your photos reflect your ability to capture great images with the GF-1 +20mm.
    Tough for me pick a favorite. 3 that I really like are the sparks from the cutting torch, the flame photo & the last posted "Like Trees in a Forest". Keep them coming.

    These are superb images, sharp, well exposed with great composition - thank you so much for sharing them.
    Once again, that "Old GF1" comes up trumps - I love mine and it looks like you have a good relationship with yours.

    These are in another thread but I thought to add them here as well.

    Those are wonderful pixs being shot on the fly. Your 20/1.7 doesn't need a filter, it needs welding goggles.:cool:
