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 1st (K24A1 engine model) and 2nd clutch waved-plate about 60-degree apart from the bottom with holding the waved-plate by its circumference, and rotate the 1st (K20A4 and K20A5 engine models), 3rd, and 4th clutch waved-plate about 72-degree or 54-degree apart from the bottom. There will be presented a top (E) of a phase difference. Do not rotate the waved-plate with holding its surface, always rotate it with 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: 0.05 mm (0.002 in.) minimum 

5.Rotate the 1st (K24A1 engine model) and 2nd clutch waved-plate about 60-degree apart from the top, and rotate the 1st (K20A4 and K20A5 engine models), 3rd, and 4th clutch waved-plate 54-degree or 72-degree apart from the top. The dial indicator should be at the bottom of a phase difference (F and H), and zero the dial indicator.

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