S2 clutch change advice.

[Tashman]

Doing a clutch change on my S2 in slow-time over the past month, got as far as taking the old one out and ordering the new one. Its a Sachs clutch kit, but its the spring clutch type, porsche tell me the rubber doughnut type is no longer available. Is there anything different I should do when fitting it? (This is the first clutch I've done on any car ever) It comes with the release bearing also (and some shims and circlips) and the pressure plate, is there anything else I need to do whilst there? I can't help thinking pulling the pilot bearing and flywheel off would be opening a can of worms? Can't I just clean the flywheel with brake cleaner?

Watching that Tv program yesterday "The Garage" where they're changing a clutch on a 944 also, and the whole problem turned out to be wear on the clutch-release lever fork. Mine looks a bit worn too so I thought I'd change it while I'm in there but Porsche tell me that it's longer available too. Anyone know where I can get one in the UK? I dont wanna be taking the whole car apart again in a few weeks, its taken me long enough!!
Cheers for help and advice. []

Welcome to the world of 944 clutch changes !

Look on the positive side, it's a lot easier on an S2 than a Turbo as you don't have all the Turbo plumbing to contend with.

With regard to the spigot bearing and flywheel, my advice would be to pull the flywheel off - only 9 bolts (cheap to replace too) and whilst you're in there change both the bearing AND the rear crankshaft oil seal. The last thing you want to be doing is either of these jobs with a new clutch in place.

Having pulled the flywheel you can then have it inspected and checked for wear/ trueness and if necessary have it skimmed/ faced up - not a big job nor too expensive.

With regard to the clutch fork, if you're worried about wear, again take it to an indie or Porsche specialist and ask them to check. They are available but not in the UK, Lindsey racing have a supply in the US - takes a few weeks and costs import duty but still available. - I know this...... as had to order a Turbo one last year

Good luck with the project and keep us posted,

Chris

I saw that episode of "the Garage" too, and I reckon the clutch release fork, which in their case was bent, rather than worn, was damaged while the "sports car specialist" was hammering the torque tube about in an effort to get it to clear the bellhousing. As suggested above however, worth getting it checked while its out.

Replace all the bolts seciring the outer to the flywheel as they always chew taking them out if they have been in for a while. Change the bearings and the sleeve that the fork goes on as they will be knacked as well and it makes for a lighter pedal. Change the crank seal (which is a pain to get out and in!). Flywheel bolts never wear and usually don't need replaced unless the head is chewed. Have a good look at your slave cylinder, if it has not been done, worth chucking one on when in there. Bleed it from the flexi as well as that is at the highest point.
