CHANGES ON CLUTCH/
INSTRUCTIONS FOR REPLACEMENTS
Clutch discs with symmetric liner springs and a longer hub were introduced as from
December, 1980 in standard production to improve engaging behavior.
In conjunction with this changes were also necessary on the clutch intermediate ring,
central shaft I and release bearing tube.
From 1984 models on cars have a separate test connection to check the ignition timing.
This changed the dowel pin centering of the clutch in such a manner that the intermediate
ring can now only be installed in correct position to the flywheel.
