Saturday I was leaving a friend and fellow club member's house when all of a sudden I heard a "POP" and then my engine began to rev. I thought to myself that this cant be good as the car was slowing to a stop. I had lost all motion, no gears forward or reverse. It felt as if all of the internals of the transmission had just vanished because there were no noises coming from the gearbox. I was able to put the car into any gear and push it! Now I know you can't do that but I did. Fortunately for me I only got a block away from the garage which is well stocked to perform any needed repairs. I came back with some help today to remove the transmission and to figure out what had gone wrong with it. I was preying it was nothing inside the gearbox. When we removed the transmission and the pressure plate this is what we found.

This was a 7 year old Sachs clutch disc with less than 25k miles on it. The clutch was not abused but the car is occasionally driven spiritedly. If you look carefully you will notice that the outer friction ring is held to the hub at only 3 points! On the LUK or Borg & Beck units they are held in place at 7 and 10 points and each point is fastened with 2 rivets not just 1 as Sachs does it. Fortunately one of my friends had a brand new LUK disc and we were able to get the car back on the road. This was such a strange mode of failure that I had to share it. Also I would reconsider ever installing one of these clutch discs ever again it just does not seem like a very robust design.
