As regulars of this forum will know I'm in the process of changing the clutch on the S2 I've recently purchased. Apart from having to slot a siezed bolthead to get it out, all went well. I completed the job on my own, the most difficult part being removing and installing the transaxle. Having done the job before on a 924 I remembered where the balance position of the transaxle was so that made it a little easier to remove. Putting it back in was more difficult, having to try to balance it on the trolley jack as it went up into position.
However all is not well, on completion I started the car only to hear this loud screeching sound. I thought the started motor was not disengaging from the toothed ring. I removed it but all looked OK. I started the engine again, still the loud screeching, then the engine went dead. It would turn over but not fire up.
After many hours of head scratching, I've now found the problem and it could be a lesson for anyone changing the clutch on one of these cars. When I put the housing for the reference sensor back on, I didn't notice that it has a slotted bolt hole that gives a distance adjustment to the flywheel. By sods law, it found the position nearest the flywheel, so when the sensor was inserted and locked down it was forced against the flywheel, hence the screech. After a short time the sensor stopped working due to the machined groove in the end of it, hence the engine stopped. Now have to phone Swindon OPC tomorrow morning and order a new sensor, fortunately the flywheel is not damaged, just a little polished. Not pleased, but at least I found the problem, it certainly had me worried and at least I'll not be taking it all apart again which I was beginning to think may have been necessary.
I should have read Clark's Garage website more carefully, I can now see it explains how to adjust a 0,8 mm gap with the use of a 0,8 mm thick washer glued to the end of the sensor. At least I now have a dummy tool sensor on which to glue the washer!!
