Porsche 951 Project Continues. Tranny Reseal/Clutch Install RennsportKC

I feel like I have been hit by a truck this week. I have so much work stacked up with no end in sight, that every day has been a killer this week. Can’t complain about the work though, we are lucky to have so much support from our awesome customers……I just need to figure out how to clone myself.

To get the clutch out with the one piece crossover pipe, the intake has to come off so you can remove the crossover pipe at the turbo. The end result is something that looks like this. I didn’t pull the timing belt/waterpump off yet as I didn’t want Fred to have a heart attack. You know what they say, you like the result of brain surgery, you just don’t want to watch.

Various clutch pieces. The clutch fork is hammered, here it is pictured in front of the replacement fork. Hard to tell, but there is significant difference in finger height.

And the release bearing guide. Pretty nasty looking.

I had to laugh when I pulled the fabspeed exhaust off. They didn’t use a copper gasket that comes with the exhaust….instead they just smeared some rtv up there. Yea….that will seal up just fine, lol. I have a new gasket coming!

While the intake was off, I noticed the turbo was caked in oil, pretty typical for the feed line o ring to harden up and leak.

Old seal is flat as a rubber pancake.

Compared to the new viton replacement.

And the new clutch assembly going back together. Notice the 2 piece crossover pipe.

And the bellhousing bead blasted, new guide tube installed, ready to go back in.

When I pulled the bellhousing off, I found the reference sensor connectors had previously been broken and were just taped together, so I replaced the two sensors as well.

These ends will break off in the female end of the harness. When that happens, a typical hot no start condition will occur.

And the bellhousing and torque tube back together.

New starter. The old starter was broken and had been jerry rigged to work. Homey don’t play that……new starter.

Yuck! A few seals leaking on the transaxle. Typical to have the output shaft seals leak, gear selector shaft seal, and cover plate gasket.

A round of new gaskets go on while I have it out.

Odds and ends. While the pump was out, best to reseal it as well since it was leaking.

Fairly basic to reseal. A main body o ring, funky shaped oring, and wiper seal at the pulley.

And much better! Stay tuned

Hi I’m about to address my slightly greasy transaxle. I was planning on replacing the drive shaft seals and putting in swepco since I’m putting on new CV’s anyway, and it is pretty straight forward. But how about that back cover gasket? I know you have to remove the end cap and bolt that holds rear bearing to the primary shaft before taking the back cover off. But do I need to reset preload on the shaft/bearing after replacing the gasket and reinstalling the back cover? Or is that only necessary for the conical pinion and diff bearings? Since you have just done this you can probably give me a better answer than most. Thanks, keep up the good work I enjoy your blog a lot!
