Note:
As the maximum axial run-out of the
starter motor toothed wheel must not be
exceeded, the axial run-out of the fly-
wheel should be measured on the contact
surface of the starter motor toothed
wheel prior to shrinking on the starter
motor 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.
Turn the flywheel a few revolutions by hand and
observe the reaction of the dial gauge.
