2. Installation of the clutch coupling on the flywheel
The clutch coupling is installed on the
flywheel as follows:
- mount a splined workholder (fig. K-10)
in the bearing of the flywheel.
- mount the first driven disk 2 (fig. K-9)
on the workholder with the hub short end
facing the flywheel 1.
- mount center plate 3 so that the tan-
gential plates are fitted over the flywheel
pins with the installed long bushings 17,
then mount short bushings 15 on the flyw-
heel pins with tangential plates.
- mount two bushings 7 of middle length
on the other three flywheel pins.
- mount the second driven disk 2 on the
workholder with the hub short end facing
the flywheel.
- mount assembled clutch disks (back
plate 8 with pressure plate 4) on the flyw-
heel pins with the bushings, fix with the
nuts (the torque of the nuts 70 to 90 Nm)
and unscrew the manufacturing bolts.
- adjust the position of the release lev-
ers.

Adjustment
of
the
position
of
the
release
levers
Make adjustment of the position of the
release levers as follows:
- screwing the adjusting nuts 9 (fig. K-9)
in or out, adjust the position of the release
levers for the dimension of 14±0,5 mm from
the lever mounting surfaces to the face of
the back plate hub. The dimensional differ-
ence for some levers shall not exceed 0,3
mm.
- after adjustment mount the lock plates
11.
- remove the workholder.
4. Adjustment of the position of the back plates
Make adjustment of the position of the
back plates as follows:
- screwing/unscrewing the adjusting
bolt 21 (fig. K-9) ensure such adherence
of thrust plates 19 to the bolt 18 that a
probe 0.1 mm would pass between facep-
lates of thrust plates 19 and end surface
of the bolt 18 with light effort
- after adjustment of the position of the
back plates fix lock nuts 20.
