(1) Remove valve body.
(2) Remove accumulator pistons with compressed
air (Fig. 82). 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, col-
lapsed or distorted springs. Replace case if piston
bores are damaged.
(2) If small cushion spring in any piston must be
replaced, remove spring retainer clip and remove
spring from piston (Fig. 83). 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.
