A/T Clutch Wave-plate Phase Difference Inspection

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 clutch wave-plate.





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

3. Rotate the clutch wave-plate of the 1st, 1st-hold, 2nd, 4th, and 5th clutches about 60-degrees while holding the clutch wave-plate by its circumference, and rotate the 3rd clutch wave-plate about 72-degrees or 54-degrees while holding the clutch wave-plate by its circumference. The dial indicator should be at the top (D) of a phase difference. Do not rotate the clutch 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 clutch wave-plate between the bottom and top.






5. Rotate the clutch wave-plate of the 1st, 1st-hold, 2nd, 4th, and 5th clutches about 60-degrees, and the 3rd clutch wave-plate about 54-degrees or 72-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 clutch wave-plate by following steps 3 thru 5.

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