4. Zero the dial indicator (4).
5. Push the rotor (2) downward evenly as close to the shaft as possible and record the highest reading. Repeat this measurement in three more locations and calculate the average of all four measurements. This is the total amount of clutch clearance.
6. The total clutch clearance must be between 1.2 mm and 0.7 mm (0.047 in. and 0.028 in.). If the total clutch clearance is not within specifications, select a larger or smaller spacer as needed, and re-check clutch clearance.
