CYLINDER SEAL REPLACE
Rotate
the
gland
until
the
gland
retaining
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 ac-
tive surface of the cylinder rod with
the vise. Damage to the rod could
result.
4.
Apply
a
lubricant
(such
as
Lubriplate
#105)
to
the
piston
and
teflon
ring.
Insert
the
cylinder
rod
assembly
into
the
cylin-
der
tube.
IMPORTANT: Ensure that the piston
ring
fits
squarely
into
the
cylinder
tube
and
piston
groove,
otherwise
the
ring
may be damaged and a leak will oc-
cur.
5.
Rotate the gland with a spanner
wrench
until
the
hole
(drilled
into
the
re-
taining
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.
