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 25 mm (1.00 inch) along the outer circumference of the flywheel face, and record measurements at each point.
The difference between two consecutive measurements must not be more than 0.03 mm (0.001 inch), which is the maximum permissible flywheel face runout.Flywheel Runout
