(for bores 1-1/2" to 4")

The cylinder is made to be disassem­bled from the rod end only. To do this,
secure the rod guide and loosen the
body using a strap wrench or similar
device. With the rod guide removed,
the body seal, rod wiper, rod seal, rod
bearing, and cushion seal (if present)
can be removed and discarded. Care
should be taken not to scratch the
sealing surfaces. The piston-rod as­sembly can then be removed from the
rear head-body assembly. Both piston
seals and the cushion retaining rings
(if present) can then be removed and
discarded with the bearing strip and/
or the retract cushion seal (if present).
The rear head should not generally
need to be removed.

All parts should be thoroughly cleaned
and examined for wear. Before instal­lation, all seals should be lubed. The
piston seals are installed with the
cavities facing away from each other.
The cushion seal (if needed) is in­stalled with the cavity facing the piston
and retained under the washer with
a new retaining ring. The two pieces
of the retaining ring snap together in
the groove. If used, the wear strip is
installed next between the piston seals.
The piston-rod assembly can then be
inserted into a well-lubed body tube.
Care should be taken not to damage
the seal on the body threads.

The bore of the rod guide should be
lubed before the new rod bearing is
pressed in. This is done from the front
side of the rod guide and, when fully

in place, should be ush with the back

side of the wiper groove. The rod seal
can then be inserted beneath the rod
bearing with the cavity facing the pis­ton. The wiper is then installed in its
groove. Finally, the body seal should
be inserted in the groove on the
threaded end of the rod guide.

Before threading the rod guide into
the body, the threads should be lubri­cated. Carefully, slide the rod guide
over the rod end ensuring that the
seal engages its mating surfaces
correctly. Secure the rod guide and
begin threading the body onto the rod
guide. Torque the body on the rod guide
according to Table 1 with a strap
wrench or similar device.
