928 S V8-4957cc 5.0L (1985)
Clutch Release Fork: Service and Repair
-
Unscrew ball stud after removing clutch housing. See: 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).
