SERVICE PROCEDURES

Flywheel Runout, Manual Transmission

  1. Remove spark plugs (12405).

  1. Install Dial Indicator with Bracketry TOOL-4201-C or equivalent so indicator points rest on face of the flywheel (6375).

  1. NOTE: Refer to the Specifications portion of the appropriate engine section in this group for flywheel runout specifications.

    Hold flywheel and crankshaft (6303) forward or backward as far as possible to prevent crankshaft end play from being indicated as flywheel runout.

  1. Set indicator dial on zero mark. Turn flywheel one complete revolution while observing total indicator reading (TIR). If TIR exceeds specification, flywheel and ring gear assembly must be replaced.

  1. 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.
