8T-5096 Dial Indicator Gp 1 Face Runout (Axial Eccentricity) of the Flywheel
Illustration 1 g02166614
Checking face runout of the flywheel
(1) 7H-1645 Holding Rod
(2) 7H-1945 Holding Rod
(3) 7H-1942 Dial Indicator
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. The applied force 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. Refer to Testing and Adjusting, "Finding Top Center Position for No. 1 Piston".
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 0.13 mm (0.005 inch), which is the maximum permissible face runout (axial eccentricity) of the flywheel. Bore Runout (Radial Eccentricity) of the Flywheel

Checking bore runout of flywheel
(4) 7H-1940 Universal Attachment
Install 7H-1942 Dial Indicator (3). Make an adjustment of 7H-1940 Universal Attachment (4) 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 0.15 mm (0.006 inch), which is the maximum permissible bore runout (radial eccentricity) of the flywheel.

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 0.13 mm (0.005 inch).
