I noticed that the rubber around the inside bore, surrounding the pin, is starting to pull away around the edge.
This is the clutch fork actuator that bolts into the bellhousing.
Is this a potential problem or does the rubber just provide a water/fluid seal?? What's the best way to repair this if posible.
Cheers
Stu

This is the clutch slave cylinder obviously. Repair parts for it are available in a rebuild kit. The accordian, or bellows shaped rubber that's visible on the outside normally tears before the other more important internal hydraulic seal wears down and fails. The "accordian" seal is just a water/dust protector. New. they already have a small hole punched in them for air in-out.
I usually keep a spare rebuilt slave cyl and/or new rebuild kit on a shelf ready to go in, and swap/rebuild them roughly every 2 years..
I've never removed the slave just to replace that outer dust/water seal. The inner hydraulic seal will let you know it's time for a change as the pedal begins to drop, and requires pumping to get it back. As it worsens, you'll find the pedal on the floor when you get in in the morning. This worsens further in colder weather..

Smoothie, I usually keep a spare around for my 944 as well, as I was changing them at regular intervals. Instead, now I change the brake fluid - it eats at the seals if left more more than 2 years.

Gentlemen,
I have a failed slave cylinder to rebuild. The push rod length underneath the rubber cover has corroded, is rough, and is reduced in diameter. The piston stops 1/8 inch short of the cylinder end and won't travel farther. Does the rebuild kit include a new push rod and is there a trick to get the piston out?

Thank you.

Corroded push rod wouldn't be unusual. I doubt it's bad enough to cause problems, but you'll have to judge it for yourself, or post pics..
Mine's been rebuilt several times, and the same olde rust pitted rod goes back in every time - no problems with it..


I usually use these "external retaining ring pliers" to remove the piston -

Say... what size is the bleeder valve?
I broke mine trying to undo it on the '82 engine and it is so rusted on the '80 engine that I'm not even going to try to take it out.
