Transmission seals.

[Sean]

Alright,

I need some pointers here. I'll be picking up a 30mm socket tomorrow for the output shaft seal.

But, I was trying to work on the selector shaft seal, and I really am not sure how I'm gonna go about getting it out?

I can do everything but get the seals out. I don't ahve a puller, and don't really wanna buy one. So, what;s the next best thing?

Thanks for your help!

Does anyone have anything to offer? I need to get these replaced soon...

Thanks.

a small screw driver and a hammer. knock a hole through it and pry it out very carefully making sure not to scar the trans.

yup.

From the hayne's manual:

"Pry out the selector shaft seal with a seal removal tool or a small screwdriver. Make sre you dont damage the seal bore while prying out the seal."

They make seal puller tools... they are very cheap, and they *work*

Any auto parts store should stock one.

Using a screwdriver is risky. If you scratch the metal sleeve the seal presses into it will leak.

So, schucks should have one then too?

I was thinkin it was a BMW specific part, but if not, I'd consider buying one elsewehre.

When you say they work - you mean they aren't risky then, correct?

Thanks guys!

schucks will have it, work = less risky than screwdriver. naturally, you can still mess it up.

Pretty sure that 30mm socket needs to be a deep socket and thin walled as well, just so you know :)

This tool was the hardest to find when i was looking.

What I finally ended up doing was going to autozone, buying a cheap deep socket 30mm and grinding it down until it fit.

worked fine

I've realized the same thing, and I think I will give this same thing a shot.

How'd you go about getting your seals out? Someone else suggested that I get a type of screw driver with a hook on the end or somethin like that?

Thanks!

Bump

I'm going to be replacing my guibo next week, and I'm wondering if I should replace the two accessible transmission seals while I'm in there (output shaft and selector shaft seals).

It looks like I'll need a seal removal tool and a 30 mm socket, huh? (sigh.. every job seems to require a new tool) Do people normally replace these when they're in there, or just wait until they leak/fail?

Thanks

[Sean]

Those rear ones are usually ones to wait to fail - since if they leak, you can replace them fairly quickly and painlessly.

I could NOT, for the life of me, replace the selector shaft seal after I started screwing with it. So I paid a local tranny shop $30 to replace it for me. (I brought the tranny to them) I had the other seals, but left them alone (probably should have just had them replace all of them). Teh 30 MM DEEP socket is VERY hard to find.

But, when i was talking to the mechanic at the tranny shop - he basically told me - if it isn't leaking - leave it alone.

So, unless you have some major leaks - they should be fine. I think the seal to worry about the most is the input shaft seal.

[rumatt]

Thanks Sean. I think you convinced me to leave them.
