8T-5096 Dial Indicator Gp 1
Illustration 1 g00812156
Checking face runout of the flywheel
Refer to Illustration 1 and install the dial indicator. Always put a force on the crankshaft in the same direction before the dial indicator is read. This will remove any crankshaft end clearance.
Set the dial indicator to read 0.0 mm (0.00 inch).
Turn the flywheel at intervals of 90 degrees and read the dial indicator.
Take the measurements at all four points. The difference between the lower measurements and the higher measurements that are performed at all four points must not be more than 0.15 mm (0.006 inch), which is the maximum permissible face runout (axial eccentricity) of the flywheel.

Checking bore runout of the flywheel
Install 7H-1942 Dial Indicator. Make an adjustment of 7H-1940 Universal Attachment so the dial indicator makes contact on the flywheel.
Set the dial indicator to read 0.0 mm (0.00 inch).
Turn the flywheel at intervals of 90 degrees and read the dial indicator.
Take the measurements at all four points. The difference between the lower measurements and the higher measurements that are performed at all four points must not be more than the following values for the maximum permissible bore runout (radial eccentricity) of the flywheel. Maximum flywheel bore runout ... 0.15 mm (0.006 inch)

Checking the flywheel clutch pilot bearing bore
To find the runout (eccentricity) of the pilot bearing bore, use the preceding procedure.
The runout (eccentricity) of the bore for the pilot bearing in the flywheel must not exceed the following value: Maximum runout of the bore for the pilot bearing in the flywheel ... 0.13 mm (0.005 inch)
