- Turn the flywheel one complete revolution while observing the total indicator runout (TIR). The flywheel TIR must not exceed the specification.
- If the flywheel TIR does not exceed the specification, proceed to the next step in this procedure to check the ring gear runout.
- If the flywheel TIR exceeds the specification, remove the flywheel. Refer to
CLUTCH
. Check for burrs between the flywheel and the crankshaft mounting flange. If burrs exist, remove them. Check the crankshaft flange runout.
- If the crankshaft flange TIR does not exceed specification, and no burrs were found between the flywheel and the crankshaft mounting flange, install a new flywheel.
- If the crankshaft flange TIR does not exceed specification, but burrs were removed from between the flywheel and the crankshaft mounting flange, reinstall the flywheel. Refer to CLUTCH . Recheck the flywheel runout. If the flywheel TIR exceeds the specification, install a new flywheel.
- If the crankshaft flange TIR exceeds specification, repair as necessary. Reinstall the flywheel. Refer to CLUTCH . Recheck the flywheel runout. If the flywheel TIR exceeds the specification, install a new flywheel.
- Install the special tool against the ring gear face adjacent to the teeth. Zero the dial indicator.
