MAINTENANCE AND SERVICE
Now insert the seal into the gland from the inner end. Position the seal in its
groove, and release and remove the tool. Press the seal into its seat the rest of
the way by hand.
NOTE: Threaded gland is shown in diagram for reference only.
2.
Install the new piston ring, rod wiper, O-rings, and backup washers, if
applicable, on the piston. Be careful not to damage the seals. Caution must be
used when installing the piston ring. The ring must be stretched carefully over
the piston with a smooth, round, pointed tool.
3. Slide the gland onto the cylinder rod being careful not to damage the rod
wiper. Then install the spacer, or flat washer (if so equipped), small O-ring, piston,
and hex nut onto the end of the cylinder rod.
4. Secure the cylinder rod (mounting end) in a vise, with a support at its cen-
ter. Torque the nut to the value shown on the chart for the thread diameter of the
cylinder rod.

IMPORTANT: Do not contact the active surface of the cylinder rod with the vise. Damage to the rod could
result.
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. Apply a lubricant (such as Lubriplate #105) to the piston and teflon ring. Insert the cylinder rod assembly
into the cylinder tube.
6.
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.
Rotate the gland until the gland retaining rod forms a ring between the gland and the cylinder tube. When com-
plete, 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.
WARNING! Cylinders serviced in the field are to be tested for leakage prior to the attachment being
placed in work. Failure to test rebuilt cylinders could result in damage to the cylinder and/or
the attachment, causing severe personal injury or even death.
