CYLINDER SEAL REPLACEMENT
The following information is provided to assist you in the event you should need to repair or rebuild a
hydraulic cylinder. When working on hydraulic cylinders, make sure that the work area and tools are clean
and free of dirt to prevent contamination of the hydraulic system and damage to the hydraulic cylinders.
Always protect the active part of the cylinder rod (the chrome section). Nicks or scratches on the surface of
the rod could result in cylinder failure. Clean all parts thoroughly with a cleaning solvent before
reassembly.
DISASSEMBLY PROCEDURE
NOTICE! Do not contact the active surface of the cylinder rod with the vise. Damage to the rod could
result.
RETAINING RING TYPE GLAND
1. Mount the cylinder tube securely in a vise. NOTICE: Do not clamp too tight and distort the tube.
2. Rotate the gland with a spanner wrench (available from your dealer), until the gland retaining ring
appears in the milled slot.
Pry up the end of the gland retaining ring with a pointed tool. Rotate the gland with a spanner wrench while
removing the retaining ring. NOTE: The gland and piston seal(s) can be pulled out and cut as they
appear in the milled slot during disassembly. After cutting, pull them on out through the milled slot.
3. Pull the cylinder rod from the cylinder tube.
4. Inspect the piston and the bore of the cylinder tube for deep scratches or galling. If damaged, the
piston and cylinder tube must be replaced.
5. Remove the hex nut, piston, flat washer or spacer tube (if so equipped), and gland from the cylinder
rod. If the cylinder rod is rusty, scratched, or bent, it must be replaced.
6. Remove and discard all old seals.
ASSEMBLY PROCEDURE
NOTICE! Replace all seals even if they do not appear to be damaged. Failure to replace all seals may
result in premature cylinder failure.
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. A special installation tool 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.
19
MAINTENANCE
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.
