1. Begin by wiping all surfaces before gauging.
2. Secure the dial indicator to the flywheel housing with the
gauge finger on the flywheel near the outer edge. Rotate
flywheel.
3. The total indicated difference between the high and low
joints must be 0.178 mm (0.007 in) or less for a 35.6 cm
(14 in) clutch, 0.203 mm (0.008 in) or less for a 39.4 cm
(15.5 in) clutch.

Use a marker or soapstone to mark the high and low
points.
Total difference between high and low points should not
exceed 0.203 mm (0.008 in).
5. Move the gauge finger to contact the face of the engine
flywheel housing.
Again, rotate the crankshaft and then mark high and low
