CYLINDER SEAL REPLACE
Rotate the gland until the gland retain-
ing rod forms a ring between the gland
and the cylinder tube.
When complete, the bent end of the
gland retainer ring should be hidden
(not turned so it is exposed in the slot)
to prevent it from popping out.

1. After installing the rod seal
inside the gland as shown in the
general instructions, install the
external seal.
NOTE: Threaded glands may have
been equipped with a separate O-
ring and backup washer system or a
polypak (all-in-one) type seal.
Current seal kits contain a polypak
(all-in-one) type seal to replace the
discarded seal types on all threaded
glands.
THREADED TYPE GLAND
shown on the chart for the thread
diameter of the cylinder rod.(see chart)
IMPORTANT: Do not contact the
active surface of the cylinder rod with
the vise. Damage to the rod could
result.
4 . Apply a lubricant (such as Lu-
briplate #105) to the piston and teflon
ring. Insert the cylinder rod assembly
into the cylinder tube.
I MPORTANT: Ensure that the piston
ring fits squarely into the cylinder tube
and piston groove, otherwise the ring
may be damaged and a leak will occur.
5 . Rotate the gland with a spanner
wrench until the hole (drilled into the
retaining slot of the gland) appears in
the milled slot of the cylinder tube.
Insert the hooked end of the gland
retaining rod into the hole.
