Forward Clutch: Reassembly
WARNING: This page is about a different variant/trim than selected.
- Coat NEW piston "O" ring with ATF. Install "O" ring on forward clutch piston. Using hand pressure, press piston into forward clutch drum. Ensure "O" ring is not damaged. Set piston return springs and clutch balancer in position.
- Position spring seat on a press. Compress piston return springs. Using snap ring expander, install snap ring in forward clutch drum groove. Ensure end gap of spring is not aligned with gap in spring retainer claw.
- Install 4 plates and 4 discs, starting with plate and alternating with disc. Install flange on top of disc. See Figure. Install snap ring. Ensure end gap of snap ring is not aligned with cutouts of forward clutch drum.
- Check forward clutch pack clearance. Install forward clutch on oil pump assembly. Using a dial indicator, measure forward clutch pack clearance by applying and releasing 57 psi (4 kg/cm2 ) of compressed air to oil pump. See Fig 1. Clutch pack clearance should be .055-.071" (1.40-1.81 mm). If clutch pack clearance is not within specification, disassemble and reassemble forward clutch components.
- Measure clutch pack clearance again. If measurement is still not within specification, replace flange. Flange is available in 4 thicknesses from .118" (3.00 mm) to .142" (3.60 mm) in increments of .008" (.20 mm).
CAUTION:
In the following step, do not compress piston return spring more than .079" (2.00 mm) past snap ring groove. This prevents piston from becoming deformed. DO NOT expand snap ring excessively.
