Replacing starter gear ring
Fig. 5
Remove the flywheel.
Drill the starter motor toothed wheel and break
with a chisel.
Caution:
In doing so, do not damage the flywheel.
Fig. 6
Note:
As the maximum axial run-out of the
starter motor toothed wheel must not be
exceeded, the axial run-out of the flyw-
heel should be measured on the contact
surface of the starter motor toothed
wheel prior to shrinking on the starter mo-
tor toothed wheel.
If the required value is exceeded, replace
the flywheel.
Engage the flywheel at the hub.
Apply the dial gauge to the contact surface of the
toothed wheel.
Rotate the flywheel by hand through several re-
volutions and observe the needle deflection on the
dial gauge.

Heat the new starter ring gear to approx. 200°C to
230°C and press on as far as it will go.
Danger:
The parts are hot! Risk of burns!
Wear protective gloves.
Check the axial runout and compare with the max.
permissible value.
