Accumulator: Service and Repair
REMOVAL
1. Remove valve body.
Accumulator Piston Removal
2. Remove accumulator pistons with compressed air. Apply air through small Feed hole next to each piston bore. Catch each piston in a shop towel
as it exits bore.
CAUTION: Use only enough air pressure to ease each piston out of the bore. In addition, remove the pistons one at a time and tag the pistons and
springs for assembly reference. Do not intermix them.
3. Remove and discard piston O-ring seals. Then clean pistons and springs with solvent.
INSTALLATION
1. Inspect pistons, springs and piston bores. Replace worn damaged pistons. Replace broken, collapsed or distorted springs. Replace case if piston
bores are damaged.
Small Cushion Spring Retention
2. If small cushion spring in any piston must be replaced, remove spring retainer clip and remove spring from piston. A small hooked tool or small
thin blade screwdriver can be used to remove clip. A thin wall, deep socket, or pin punch can be used to seat clip after spring replacement.
3. Install new O-ring seals on pistons. Lubricate seals and pistons and piston bores with transmission fluid.
