Transmission rear seal change

[Greg F]

Hey guys:

I have a pretty good leak from the rear of the transmission, and drips on the ebrake drum.

My question is..Can I change that seal without taking the whole transmission out? Know it will be tough under the car, but really don't want to take the transmission all the way out if I can help it, as it was tough to get in.

Greg...call me lazy

I don't see any reason why you can't, although I've found that the first time installing is the hardest, once the clutch disk is lined up it slides in and out real easy.

Yes you can change it in car.

Remove drive shaft.

Remove all your E-brake set-up.

Remove big nut...1 1/4 I think..

Then use a either a big 2/3 arm puller to pop off the e-brake drum. I had the tranny out and used a block of wood and a regular carpenters hammer to slowly beat around the drum unit it popped off.

Now use a good seal puller...which may or may not get that old seal out. They can get stubborn after all these years. I had to chisel mine out with a couple screw drivers and a metal bar.

Then measure the OD of your output shaft, and the inside diameter of the case. Then search around here on the board for appropriate seal number. I measured mine and found that it used a SKF 15620.

Then use a small hammer, or big socket and hammer, to carefully tap in the new seal.

Here's what mine looked like...
