Face Runout (Axial Eccentricity) Of
The Flywheel Housing

Checking face runout of the flywheel housing
If you use any other method except the method that
is given here, always remember that the bearing
clearance must be removed in order to receive the
correct measurements.
1. Fasten a dial indicator to the flywheel so the anvil
of the dial indicator will contact the face of the
flywheel housing.
2. Put a force on the crankshaft toward the rear
before the dial indicator is read at each point.

3. Turn the flywheel while the dial indicator is set at
0.0 mm (0.00 inch) at location (A). Read the dial
indicator at locations (B), (C) and (D).
4. The difference between the lower measurements
and the higher measurements that are performed
at all four points must not be more than 0.38 mm
(0.015 inch), which is the maximum permissible
face runout (axial eccentricity) of the flywheel
housing.
