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. Measure the phase differences of the 1st, 1st-hold, 2nd, 4th and the 5th clutch wave-plates.

1. Rotate the clutch wave-plate about 60-degrees while holding the clutch wave-plate by its circumference. The dial indicator should be at the top of a phase difference. Do not rotate the clutch wave-plate while holding its surface, always rotate it while holding its circumference.

2. Read the dial indicator. The dial indicator reads the phase difference of the clutch wave-plate between the bottom and top.






3. Rotate the clutch wave-plate about 60-degrees. The dial indicator should be at the bottom of a phase difference, and zero the dial indicator.

4. Measure the phase difference at the other two tops of the clutch wave-plate by following steps -1 thru -3.

4. Measure the phase difference of the 3rd clutch wave-plate.

1. Rotate the clutch wave-plate about 54-degrees or 72-degrees while holding the clutch wave-plate by its circumference. The dial indicator should be at the top of a phase difference. Do not rotate the clutch wave-plate while holding its surface, always rotate it while holding its circumference.

2. Read the dial indicator. The dial indicator reads the phase difference of the clutch wave-plate between the bottom and top.






3. Rotate the clutch wave-plate about 54-degrees or 72-degrees. The dial indicator should be at the bottom of a phase difference, and zero the dial indicator.

4. Measure the phase difference at the other two tops of the clutch wave-plate by following steps -1 thru -3.

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