Replacing seals on trunnion shaft.
 

Hello everyone. I have a IH made Cub Cadet 782 that has a seal leaking on the trunnion shaft of the hydro transmission. The seal that is leaking is on the opposite side of the trunnion. I've never replaced one of these seals before and was wondering best way to go about getting seal out. I probably will have to pull the tranny to be able to do the work. Hoping all you have to do is remove the snap ring and washer and somehow pry and pull on the seal and get it out that way. Any ideas would sure be appreciated.:bigthink::beerchug:

put a small hole in the seal and screw a wood srew into it and you should be able to pull it out with some vise grips.

Thanks Tim. I assume I will have to pull the transmission to be able to do the work?

ive always done it with the trans out so im not sure it can be done in the tractor.

Tim, I was thinking of drilling a hole in the frame to be able to do what you suggest. I have a 1-1/16" drill to put the hole in frame.

Just take the rear out. Don't be one of those owners who hacks up a machine just to avoid less than 30 min worth of work. :bash2::bash2: It's not like you have to change that seal all the time. This is probably the first time it's ever been changed.

im with Jon on this one, removing the rear end is easy and doesn't take much time.

Ok..... probably longer than 30 minutes.... but like Tim said, it's easy and doesn't take that long.

Ok I will pull the tranny. Thanks Jon and Tim.

Maybe I should add, roll the whole rear end out with hydro attached.
Don't know if you understood that, or at least I do it that way and it is a simple
job, it really isn't that bad.
I'm with the 30 min, ---hour @ most guys if you haven't done it before.
I just pulled one on a 1650 today, wished it was as simple as yours, I have the hydro apart, as it is the seal on the trunion lever side.
We will help if you have questions.
