Installation, dismantling and adjustment of coupling clutch

Attention: Before starting to dismantle
the clutch coupling it is recommended that
you make marks, identifying mutual ar-
rangement of the flywheel 1 (fig. K-9), the
center plate 3, the pressure plate 4 and
back plate 8. Assemble the clutch in accor-
dance with the marks.
The clutch coupling is dismantled from
the engine as follows:
- mount three manufacturing bolts
(M12x40), having screwed them into the
pressure disk 4 (figure K-9) through the
manufacturing orifices of the back plate 7
- unscrew the nuts attaching the back plate
to the flywheel and remove the clutch plate
assembly (the back plate 7 together with the
pressure plate 4)
- remove the first driven disk 2.
- remove from the flywheel pins three
short bushings 15 and the center plate 3.
- remove the second driven disk 2.
