Clutch Wave Plate Phase Difference Inspection
WARNING: This page is about a different car, the 2007 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
- Place the clutch wave plate on a surface plate, and set SA9179NE on the wave plate.
- Find the bottom (D) of a phase difference of the wave plate, zero the SA9179NE and make a reference mark on the bottom of the wave plate.
- Rotate the clutch wave plate of the clutch about 60-degrees apart from the bottom while holding the wave plate by the circumference. The SA9179NE should be at the top (E) of a phase difference. Do not rotate the wave plate while holding the surface, always rotate the plate by holding the circumference.
- Read the SA9179NE
. The SA9179NE
reads the phase difference (C) of the wave plate between the bottom and top.
Specification: Standard: 0.05 mm (0.002 in) minimum
- Rotate the wave plate of the clutch about 60-degrees. The SA9179NE should be at the bottom of a phase difference (F and H), and zero the SA9179NE .
- Measure the phase difference at the other 2 tops (G and I) of the wave plate by following steps 3 through 5.
- If the 2 values of the 3 measurements are within the standard, the wave plate is OK. If the 2 values of the 3 measurements are out of the standard, replace the wave plate.
