1.14 FLYWHEEL<br />

12. Check the run-out of the flywheel at the clutch contact face.<br />

Figure 1-215<br />

Measuring Flywheel Runout<br />

13. The maximum allowable run-out is 0.025 mm (0.001 in.) total indicator reading per inch<br />

of radius (or 0.001 mm per millimeter of radius). The radius is measured from the center<br />

of the flywheel to the outer edge of the clutch contact face of the flywheel. Example: A 14<br />

in. clutch would allow 0.175 mm (0.007 in.) total indicator reading.<br />

14. If maximum total indicator reading exceeds, 0.025 mm (0.001 in.) per inch of radius, it<br />

may be necessary to repeat the assembly procedure until the cause can be detected and<br />

eliminated.<br />
