941b tranny removal

caterpillarRy ยท 2013-04-06 02:05

So this summer my grand father and I are finally going to finish fixing our 941 and we already know we will have to drop the transmission. So we have all the stuff to pull it I just want to know is it easier to drop it out the bottom or pull it out the top? Also we have a combined experience of 0 on power shift trannys so any info helps we also have a shop manual for the machine.

    The transmission should be removed by top and if sometime I can help am still have some transmission parts for 941

    Why the top? is it just easier or something cause my grand father and I have all the plates on the bottom off and he thought we could just drop it out the bottom with the crane truck and drag it out from under it with a come along or the winch on our d4

    If its just cause its the proper way my grandfather has dropped a transmission out of some big Michigan or Hough or something out the bottom when it was supposed to have the entire top cab and everything tooken off to be pulled out the top because it was to tall to be dropped out the bottom by digging a trench and dropping it in said trench and rolling the machine from over it then doing the same thing backwards to reinstall so the proper way is not always the only or easiest way

    To remove the transmission from a 941/951, I usualy strip them out from underneath, this is the easiest way but needs the tractor up on about 300mm of timber, if you take it out the top its a lot more work plus it still needs or is best if the tractor is up on timber so you would be advised to take it out from under the tractor, if you had a track frame off its a lot simpler still, I sometimes get these shovels bare cased so I hope I have not advized you incorrectly, the transmission repair is fairly easy a few centre punch marks might aid things, the bearings on the torque must be replaced as they knacker up often, then the pinion floting bearings might be worth a look, on the clutch pack case, dont tighten the short bolts untill all the long bolts are in place and always air test your packs after the bolts are done up, if you have a service book what can go wrong??? tctractors

    Ray, if you have a service book it will tell you the best method CAT recomend, it should say removal from the top, also removal from below with good detail etc, if its your first crack at a powershift repair, a good tip is stick at it dont do an hour here and there, the gear carrier shafts are pinned, tap them in so the shafts can be pulled free, its about 3 days work for me, thats remove, refurbish and refit,so allow about a week, a fork truck or overhead hoist will make things simple, the last 1 that I rebuilt was in a workshop with a hydraulic loader crane mounted to a massive base Hiab style, it made it very easy to do.

    We have a ford c600 crane truck that we will use. But we've been doing the repair work here there for a while more of because of time constraints and family medical issues. We don't plan to do a full blown rebuild we just want to replace whatever's broken and be done with it for a while as we don't have the money but we found a metal ring about 2-4 inches in diameter all broken up in the oil when we first drained the oil and I don't know what that could be. The trans has no pressure build up and doesn't work in any gear.
