Assembly
1. Inspect the clutch components for damage or wear. Install new components as necessary.
^ Cheek the fluid passages for obstructions. All fluid passages must be clean and free of obstructions.
^ Inspect the clutch plates for damage.
^ Inspect the clutch springs.
^ Inspect the needle bearing and seal rings for damage.
^ Check clutch hub thrust surfaces for damage.
^ Cheek clutch plates for flatness and fit on the clutch hub serrations.





2. NOTE: The special tool needs to be installed on the forward clutch piston, for a couple of minutes prior to installing it into the forward clutch cylinder.

Install the special tool on the forward clutch piston.





3. CAUTION: Care must be taken to prevent damage to the seals.

NOTE: Lubricate the forward clutch piston inner and outer seal with clean automatic transmission fluid.

Using the special tool, install the forward clutch piston assembly into the forward clutch cylinder.





4. Install the forward clutch piston spring assembly.





5. CAUTION: Do not fully depress the clutch spring compressor or damage to the spring retainer may occur.

Using the special tool, install the forward clutch piston spring retaining ring.





6. CAUTION: The forward clutch friction plates are directional and must be installed with grooves pointing counterclockwise.

CAUTION: If new plates are used, they should be soaked in clean automatic transmission fluid for at least 30 minutes before assembly.

If reusing plates, grooves must be installed counterclockwise. Install the direct clutch disc pack.





7. Install the steel clutch plates and friction clutch plates in alternating order starting with a steel clutch plate.





8. CAUTION: The retaining ring is a select fit.

Install the original selective retaining ring.
1 Install the forward clutch pressure plate.
2 Install the original selective retaining ring.





9. WARNING: Air pressure must not exceed 138 kPa (20 psi).Wear safety glasses when using compressed air. Make sure the cylinder is facing down as shown. Failure to follow these instructions may result in personal injury.

Air check the forward clutch piston.
1 Place the forward clutch cylinder with forward clutch piston facing down.
2 Install the transmission center support on the forward clutch cylinder.
3 Apply air pressure to the left port of the center support.








10. Check forward clutch disc pack free play.
1 Press down on forward clutch disc pack.
2 Using a feeler gauge, check the gap between the forward clutch retaining ring and the forward clutch pressure plate.
^ If the clearance is not within specifications, install the correct size retaining ring.
