ASSEMBLY PROCEDURE
IMPORTANT
: Replace all seals even if they do not appear to be damaged. Failure to replace all seals
may result in premature cylinder failure.
NOTE:
Seal kits will service most cylinders of similar bore size and rod diameter.
1.
Install the cylinder rod seal in the gland first. Be careful not to damage the seal in the
process, as it is somewhat difficult to install.
NOTE: A special installation tool (Part #65349) is available to help with installing the seal. Simply fit the
end of the tool over the seal so that the large prong of the tool is on the outside of the seal, and the two
smaller prongs on the inside. The lip of the seal should be facing towards the tool. Rotate the handles
on the tool around to wrap the seal around the end of the tool.
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.
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.
After installing the rod seal inside the gland, as shown in step
#1,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.
4.
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.
5.
Secure the cylinder rod (mounting end) in a vice with a support at its
center. Torque the nut to the amount shown for the thread diameter
of the cylinder rod (see chart).
