Special Tools
1. Use Dial Indicator/Magnetic Base to inspect flywheel runout.
Runout
1. Remove spark plugs.
2. Install (A) Dial Indicator With Bracketry so indicator points rest on face of the flywheel (B).
3. Hold flywheel and crankshaft forward or backward as far as possible to prevent crankshaft end play from being indicated as flywheel runout.
4. Set indicator dial on zero mark. Turn flywheel one complete revolution while observing total indicator runout reading. If reading exceeds
specification, the flywheel must be replaced.
5. If clutch face runout exceeds specification, remove flywheel and check for burrs between flywheel and face of crankshaft mounting flange. If
no burrs exist, check runout of crankshaft mounting flange. Replace flywheel or machine crankshaft flywheel mounting face sufficiently to
true-up the surface.
