People tend to break the thrust bearing from time to time. Almost everytime it's due to:
- Not greasing it regularly. Once every 30 minutes at least or more often if you run on dirty tracks or your car sees grass often.
- Improper intallation (the ring with large inner diameter goes towards the flywheel)
- Bad setup of the end play. The clutch gap (between 0.4 and 0.8mm has not a lot to do with it. But the final amount of movement the clutch housing has does. The housing should hava about 0.2-0.3mm play after everything is installed.)
- modifying the clutch weights can cause problems. Especially if the weights are not all exacly the same they will lead to improper engagement and wobbeling of the clutch shoe. That leads to the bearing failure.
Thank you Julius, you beat me to it.
