A/T Clutch Waved-plate Phase Difference Inspection

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

 

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

3.Rotate the 2nd, 4th, and 5th clutch waved-plate about 60-degrees by holding it by its circumference, and rotate the 1st and 3rd clutch waved-plate about 72-degrees or 54-degrees apart from the bottom. The dial indicator should be at a top (E) of a phase difference. Do not rotate the waved-plate by holding its surface, always rotate it holding its circumference.

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

Standard: 0.07-0.20 mm (0.003-0.008 in.) 

5.Rotate the 2nd, 4th, and 5th clutch waved-plate about 60-degrees from the top position, and rotate the 1st and 3rd clutch waved-plate 54-degrees or 72-degrees apart from the top. The dial indicator should be at the bottom of a phase difference (F and H). Zero the dial indicator.

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

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