Clutch Release Fork: Service and Repair

- Unscrew ball stud after removing clutch housing. Service and Repair-- Clutch Housing Removal/Installation

NOTE: Ball studs are locked with Loctite so that removal must be done carefully, turning back and forth several times will be necessary. Heat a removed clutch housing to about 250 °C (480 °F) to facilitate removal of the ball stud.





- Clean threads with, for example, Loctite Cleaner 0706 prior to screwing in a new ball stud (19 mm diameter instead of 10 mm dia.).
- Spread a thin coat of Loctite 270 on thread flanks. Screw ball stud version 3 with washer in clutch housing. After depletion of stocks version 3 will no longer be available. Then use ball stud version 4 with washer (tap M 8 threads in clutch housing).
- The ball stud in cars prior to Chassis Number 928 820 0491 is not screwed, but pressed in. On these cars the replacement of the ball stud will require installing a M 6 threaded insert in the bore, e. g. Helicoil.
- For ball stud version 4 (after depletion of version 3 stocks) the clutch housing has 8 mm threads (without a threaded insert).
