8T-5096     Dial Indicator Gp     1    Face Runout (Axial Eccentricity) of the Flywheel Housing
Illustration 1 g00285931
8T-5096 Dial Indicator Gp
Fasten a dial indicator to the flywheel so the anvil of the dial indicator will contact the face of the flywheel housing.
Put a force on the crankshaft toward the rear before the dial indicator is read at each point.
Illustration 2 g00285932
Checking face runout of the flywheel housing
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) .
The difference between the lower measurements and the higher measurements that are performed at all four points must not be more than 0.50 mm (0.0197 inch). These measurements are the maximum permissible face runout (axial eccentricity) of the flywheel housings.Bore Runout (Radial Eccentricity) of the Flywheel Housing

8T-5096 Dial Indicator
Fasten a dial indicator to the flywheel so the anvil of the dial indicator will contact the bore of the flywheel housing.
