  1. Place the clutch waved-plate (703) on a surface plate, and set SA9179NE  on the waved-plate.
  2. Find the bottom (D) of a phase difference of the waved-plate, zero the SA9179NE  and make a reference mark on the bottom of the waved-plate.
  3. Rotate the clutch waved-plate of the 1st clutch about 60-degrees apart from the bottom while holding the waved-plate by the circumference. The SA9179NE  should be at the top (E) of a phase difference. Do not rotate the waved-plate while holding the surface, always rotate the plate by holding the circumference.
  4. Read the SA9179NE  . The SA9179NE  reads the phase difference (C) of the waved-plate between the bottom and top.

    Specification:  Standard: 0.05 mm (0.002 in) minimum

  5. Rotate the waved-plate of the 1st clutch about 60-degrees. The SA9179NE  should be at the bottom of a phase difference (F and H), and zero the SA9179NE  .
  6. Measure the phase difference at the other 2 tops (G and I) of the waved-plate by following steps 3 through 5.
  7. If the 2 values of the 3 measurements are within the standard, the waved-plate is OK. If the 2 values of the 3 measurements are out of the standard, replace the waved-plate.
