5. b) Since 1983 Models
(Modified Starter Installation)
Remove starter or loosen starter and
suspend it from car.
Take off clutch housing cover.
If applicable, also remove catalytic
converter.
6. Remove coupling screws and push back
coupling on central shaft II. In case of long
coupling, remove plug from central tube to
unscrew rear bolt.
7. Remove release bearing sleeve mounting
bolts and push sleeve toward flywheel.
8. Mark position of pressure plate, inter-
mediate plate and flywheel in relation to
each other for installation later.
For dowel pin centered clutches drive
the cylindrical pins in direction of
pressure plate with a punch far enough so
that they are beyond the centering bore
of the flywheel. Check visually at opening
of intermediate plate (arrow).
Beginning with 1984 models one of the
three centering pins is stepped (6 mm dia.
in area of intermediate ring/pressure plate
and 8 mm dia. in flywheel).
Consequently the intermediate ring can
only be installed in a certain position to
the flywheel (see intermediate ring on
page30-16a).
Remove stepped centering pin (large bore
in flywheel) completely.
This is only possible in direction of the
flywheel.
Drive the other two centering pins in
direction of pressure plate as described
above, until they are beyond the centering
bore of the flywheel (do not remove
completely).
