Make sure the bearing friction ring is in the
correct position.
The bearing friction ring is in the
correct position when the inner
diameter of the ring has approx. the
same clearance to the outer
diameter of the notch in the primary
mass. Refer to Fig. 85 - 58.
If the friction ring
 touches the bearing bushes
 is below the secondary mass
thus you cannot see the inner
diameter completely
carefully lift the secondary mass and
move the ring in the correct position.
Use a small screwdriver.
(12)
If the friction ring is damaged after the
mechanical inspection (refer to Fig. 85 - 59),
cut off the ragged area of the ring with a
sharp knife.
If the width of the ring is less than
50% or the ring gets broken, replace
the two-mass flywheel.
Refer to Fig. 85 - 60.

Put the friction ring in the correct position.
Carefully lift the secondary mass and
move the ring in the correct position.
Use a small screwdriver.
The bearing friction ring is in the
correct position when the inner
diameter of the ring has approx. the
same clearance to the outer
diameter of the notch in the primary
mass. Refer to Fig. 85 - 58.
Also small bending of the pick-up ring can cause engine operating
problems. Refer to Fig. 85 - 62 and Fig. 85 - 63.

Examine the pick-up ring for bends.
If the pick-up ring teeth are out of
shape (are bent), replace the two-
mass flywheel.
Refer to Fig. 85 - 61, Fig. 85 - 62
and Fig. 85 - 63.

Examine the starter ring for signs of wear or
damage at the gear teeth.
Each tooth must have minimum 95%
of the volume.
If you find signs of wear or damage,
replace the two-mass flywheel.
Refer to Fig. 85 - 64.

If you find damage on the gear teeth of the
starter ring, examine the starter.
If the starter is damaged, replace
