| 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 clutch waved-plate about 56-degrees or 67-degrees apart from the bottom while holding the waved-plate by its circumference, and rotate the 3rd and 5th clutch waved-plate about 60-degrees apart from the bottom while holding the waved-plate by its circumference. The dial indicator should be at the top (E) of a phase difference. Do not rotate the waved-plate while holding its surface, always rotate it by holding its circumference. |
| 4. | Read the dial indicator. The dial indicator reads the phase difference (C) of the waved-plate between the bottom and top.
|
| 5. | Rotate the 1st clutch waved-plate about 67-degrees or 56-degrees from the top, and rotate the 3rd and 5th clutch waved-plate about 60-degrees. 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 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. |
