A/T Clutch Wave-Plate Phase Difference Inspection (A/T)




A/T Clutch Wave-Plate Phase Difference Inspection

1. Place the clutch wave-plate (A) on a surface plate, and set a dial indicator (B) on the wave-plate.





2. Find the bottom (C) of a phase difference of the wave-plate, zero the dial indicator and make a reference mark on the bottom of the wave-plate.

3. Rotate the wave-plate about 60-degrees apart from the bottom while holding the wave-plate by its circumference. The dial indicator should be at the top (D) of a phase difference. Do not rotate the wave-plate while holding its surface, always rotate it while holding its edges.

4. Read the dial indicator. The dial indicator reads the phase difference (E) of the wave-plate between bottom and top.





5. Rotate the wave-plate about 60-degrees. The dial indicator should be at the bottom of a phase difference (F and G), and zero the dial indicator.

6. Measure the phase difference at the other two tops (H and I) of the wave-plate by following steps 3 thru 5.

7. If two of the three measurements are within the standard, the wave-plate is OK. If two of the three measurements are out of the standard, replace the wave-plate.
