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 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. Measure the phase differences of 1st, 1st-hold, 2nd, and 3rd clutch wave-plates.
-1 Rotate the clutch wave-plate about 60-degrees while holding the wave-plate by its circumference. The dial indicator should be at the top of a phase difference. Do not rotate the wave-plate while holding its surface, always rotate it by holding its circumference.
-2 Read the dial indicator. The dial indicator reads the phase difference of the wave-plate between the bottom and top.




-3 Rotate the 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 wave-plate by following steps -1 thru -3.

4. Measure the phase differences of 4th and 5th clutch wave-plates.
-1 Rotate the clutch wave-plate 5-teeth or 4-teeth while holding the wave-plate by its circumference. The dial indicator should be at the top of a phase difference. Do not rotate the wave-plate while holding its surface, always rotate it by holding its circumference.
-2 Read the dial indicator. The dial indicator reads the phase difference of the wave-plate between the bottom and top.




-3 Rotate the wave-plate 5-teeth or 4-teeth. 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 wave-plate by following steps -1 thru -3.

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