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.
