Cylinder Reassembly
1
Using 400-grit emery cloth, polish the piston and
retainer chamfer angles. Remove sharp edges on
internal threads in the cylinder shell. Clean all parts
thoroughly.
2
Lubricate all new seals and O-rings with petroleum jelly.
3
Install a new O-ring in the piston ID and the two-piece
seal on the piston OD. Make sure that the inner O-ring
(round section) is installed in the bottom of the groove,
and the composite outer ring is installed on top. Install
seals from the rod end side of the piston by hooking
one side into the groove and carefully working the seal
over the piston, as shown.
4
Install the composite wear ring on the piston OD.
5
Install a new rod seal and wiper seal in the retainer ID,
and a new dual seal on the retainer OD, as shown.

Apply petroleum jelly to the piston internal O-ring
and install the piston on the rod. Tighten the nut to
130 ft.-lbs. (175 Nm).
7
Apply O-ring lube or petroleum jelly to the piston and
shell. Carefully center the piston into the cylinder shell
and using a soft-faced hammer drive the piston/rod
assembly into the shell.
IMPORTANT: Prior to loading the piston into the shell,
make sure that no sharp edges exist on the internal
threads within the shell.
