Clutch fun

I opened up the used S I bought with a slipping clutch. It was easy to find the problem as the slave cylinder pocket was full of trans oil. The pushed rod was wet and the clutch disc was coated. Input splines look OK since they were being lubed too. Now all I have to do is put it back together.

You're replacing the slave cylinder too, right?

Be sure to check all the seals in there, tranny and rear seals are not fun to do but you don't want to put it all back together and find that one of those was leaking too!

IMHO those splines do not look OK. They are only slightly worn but they are wearing.

BTW...will a failed slave cylinder foul the clutch?

Although, from your pics it isn't leaking, in fact it looks dry and dusty, the tranny input shaft seal is easy sneezy to replace. I detailed it here somewhere with pics. Prolly ought to do it since you're in there. OTOH, in 60k it hasn't leaked, it obviously ain't broke...

The slave cylinder is getting replaced. The word from the dealer was that if the slave fails then the clutch fails and you replace the slave since it cannot be rebuilt. If the rear trans seal fails(mine) then the clutch fails first and eventually the slave will fail also, from contact with the trans oil.

The clutch disc thickness was 5.5mm, the wear limit is 4.5mm and new is >6.5mm, not too bad for 60k. It probable would have gone 100k w/o the leak.

A failed slave cylinder or more specifically, a failed throwout bearing in the slave cylinder, will cause the rear input seal to leak. I don't know if it will aslo cause oil to migrate to the clutch plates.

BTW, I think those splines look good for 60K. If the splines are gonna go, they are toast by 30K, normally earlier.
