Coast Clutch: Reassembly
- Install inner and outer piston seals. Ensure seal lips face bottom of cylinder. Apply transmission fluid to seals and install clutch piston into Coast Clutch Outer Seal Sizing Tool (T95L-70010-D). If installing new clutch plates, soak in transmission fluid for at least 30 minutes. Ensure coast clutch drum check ball is free in cage.
- Remove clutch piston from sizing tool and install into coast clutch drum. Install piston springs and spring retainer. Compress springs and install retaining snap ring. Carefully remove spring compressor. Install 2 steel plates and 2 friction plates in alternating order, starting with steel plate first. See Fig 1
. Install pressure plate and secure pack with retaining snap ring.
- While pushing down on clutch pack, use a feeler gauge to check clearance between retaining snap ring and pressure plate. If clearance is not .051-.079" (1.3-2.0 mm), install correct thickness retaining snap ring.
- Retaining snap rings are available in the following thicknesses: .054" (1.37 mm), .068" (1.73 mm), .082" (2.08 mm) and .096" (2.44 mm). Once correct retaining snap ring is installed, recheck clearance.
- Apply air pressure to hole on back side of clutch assembly. Block opposite hole with finger. Piston must apply under pressure and release when air is removed.
