Last night I was staring at the transmission input shaft seal that looked a little damp as I removed the guide tube. The seal is deeply recessed with no groove - how in the world do you get out the old seal??? I'm not going to change it this time around since things are mated already, but I am curious how to do it?!

Thanks!

There is a tool that slides over the input shaft, twists into the seal and is used to pull the seal out. I believe it is a Porsche tool, but I can't recall.

Ah ha... I found it in the manual, you're right there's a fancy tool to do it... thanks

Has anyone done this seal replacement using a commonly available tool instead of the 9251 tool?.

yeah I got mine out with a seal picker and pushed the new one in using a correct sized socket - just dont push it too far or you will be taking the diff out to retrieve it, please dont ask me how I know.

Garrett, I replaced the seal in one of my transes this way. I took a large flat blade screwdriver and carefully bent one part of the seal face flat. Then I used an ice pick between the outside of seal and the trans case to carefully deform the circumference of the seal. Once I got it loose in the bore, I was able to grab it with a needle nose pliers and pull it out.

To install the new one, a 1" threaded steel pipe with a steel (not cast) coupling is a perfect tool to evenly tap the seal back in. There is no stop, so push it in just far enough so that the throwout bearing collar tightens back in. That should do it.

Interesting topic.
I have to replace the seal on my trans as well.
I have the seal sitting there, but I havent had any time to do any car work in about 4 months.
Sigh.

+1, except I haven't reached the 4 month mark yet.... working on it.
Can seem to stay around the house much lately...

Well, I was going to go the factory way, but after checking out the prices for the tools, I'll go the ghetto way.

000-721-925-10 $126.36
000-721-925-60 $125.03
000-721-925-50 $86.45

I think when the time comes I am going to use my $6 seal pick.

I'm not certain that a seal pick would get back behind it, because it is recessed about 10mm and the input shaft is in the way. I even tried bending a long screwdriver blade into a hook and using a socket on it as a mini-slide hammer. My described procedure is what worked for me.

Amazing how inventive we can get in the face of overpriced specialty tools!
