install the new O-rings, gaskets and seals con-
tained
in the service kit. One gasket should be
on each side
of. the piston O-ring (Fig. 24
cylinders). Use masking tape as indicated in
Fig. 24 & 26 to protect the O-rings from damage
during assembly.
Use extreme care when installing parts into the
cylinder. Be sure the piston and bushing O-rings
are not cut on the grooves inside the cylinder.
Carefully align the parts before attempting to
insert them into the cylinder.
After reinstalling the retaining ring
(Fig. 22B),
fully extend the piston rod until the piston
pushes the rod guide bushing up to "capture"
the retaining ring.
