removing differential from a b12

[brooksdr]

I know someone must have ask this before. I searched and can't find it, but I really need help. I tore all the gears out of the the diff on my b12 pushing dirt with the loader. There is nothing left but a ground up mess. I had a ruff time getting the old one off. The parts break down I have shows it sliding right off after removing the retaing clip. But it was not so. I have a spare diff on a parts tractor. I was wanting to remove it with out taking the cover off and messing with the small gears. Is this possible?? Is there a trick to this??? thanks for any help. Don

When I redid the diffrential on my B-12 I had to take the whole thing apart to get it off, Then I put it back together peice by peice. Sometimes the cover can get caught on the snaprign groove, you can take some emrey cloth and clean it out. Its been a while scince I've done this so I can't tell you for sure.

Look in the resources area. I've written a little how-to on replacing axle seals and replacing a diff isn't that far off as it has to come off to replace the seals.

If I recall correctly, first you remove the right hub, then you can remove the nuts from the long bolts that the gears ride on, and the diff will come off, over the left axle gear without removing the retaining ring, or taking the diff apart. If the nuts are on the outside the gears will fall out. If the nuts are on the inside behind the flange, then it will come apart as an assembly. Either way, you want the bolts through the diff with threads toward the flange when you reassemble, then it will go on as an assembly.

HubbardRA is right on. What i have done if i was sure my planetary gears were in good shape is: remove the right side wheel & hub. Leave the outer bolts in place that hold the 2 "pie plates" together & loosen all the bolts/nuts that hold it to the flange(& that keep the planetary gears in place). If you are lucky the nuts are on the flange side & you can pull it off after you have removed all the nuts, leaving the bolts in place. If the nuts are on the outside you will need a couple of similarly sized bolts and then you use them to push through the bolts and as they come out use them to push out others until you have all the bolts going through from the outside to the flange side for reassembly that way later(so it will be easier the next time). You can then pull it off in the one piece alltogether. once it is off, note the position of any & all spacers around the drive gear that is fixed to the axle by keys for later same order reassembly. The biggest pain i have had in the whole process is reinstalling that infernal retainer ring. Comes out plenty easy with a couple of small straight blade screwdrivers. Everthing else then slips off the axle.
