Part 3

Clutch Inspection





1. Inspect the clutch pistons and clutch piston check valves.
2. If the clutch piston check valve is loose or damaged, replace the clutch piston.
3. Check the spring retainer for wear and damage.
4. If the spring retainer is worn or damaged, replace it.
5. Inspect the clutch discs, clutch plates, and clutch end plate for wear, damage, and discoloration.
Clutch Discs
Standard Thickness: 1.94 mm (0.076 inch)
Clutch Flat-plates and Clutch Waved-plates
Standard Thickness
1st clutch: 1.6 mm (0.063 inch)
1st-hold clutch: 1.8 mm (0.071 inch)
2nd clutch: 1.8 mm (0.071 inch)
3rd clutch: 2.0 mm (0.079 inch)
4th clutch: 2.0 mm (0.079 inch)
5th clutch: 2.0 mm (0.079 inch)
6. If the clutch discs are worn or damaged, replace them as a set. If the clutch discs are replaced, inspect the clutch end-plate-to-top-disc clearance.
7. If any plate is worn, damaged, or discolored, replace the damaged plate with a new plate, and inspect the other waved-plates for a phase difference. If the clutch plate is replaced, inspect the clutch end-plate-to-top-disc clearance.
8. If the clutch end plate is worn, damaged, or discolored, inspect the clutch end-plate-to-top-disc clearance, then replace the clutch end plate.

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 clutch waved-plate of the 1st 2nd, 4th, and 5th clutches about 60-degrees apart from the bottom while holding the waved-plate by its circumference, and rotate the 3rd clutch waved plate about 72-degrees or 54-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.
Standard
1st clutch: 0.22 - 0.30 mm (0.0087 - 0.012 inch)
2nd, 3rd, 4th, and 5th clutches: 0.12 - 0.20 mm (0.0047 - 0.0079 inch)
5. Rotate the waved-plate of the 1st, 2nd, 4th, and 5th clutches about 60-degrees, and the 3rd clutch waved-plate about 54-degrees or 72 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 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.
