Assembly
NOTE: Lubricate seals and rings with clean hydraulic oil.
1. Install the replacement wiper ring, rod seal, buffer seal
and wear rings in the inside of the head.
2. Install the replacement O-ring and backup ring on the
outside of the head.
3. Lubricate the rod with clean hydraulic oil.
4. Slide the head, onto the rod. Tap the head with a rubber
mallet to engage the seals. Push the head about half
way down the length of the rod assembly.
5. Install the spacer onto the rod with the ID lip at the piston
end.
6. Install the setscrew in the piston with a 3/16 inch Allen
wrench until hand tight. Install the seal assemblies onto
the piston.
7. Remove the cover from the barrel.
8. With a hoist, raise the rod assembly back into a vertical
position taking care not to damage the OD seals on the
head and piston.
9. Lubricate the OD seals on the piston and head with
clean light oil and lower the assembly into the barrel.
Stop just before the head enters the barrel.
10. Place a spanner wrench on the head and turn
counterclockwise until the thread clicks, then reverse
direction to clockwise and thread in until there is no gap
between the head shoulder and top of barrel.
11. Using a 5/32 inch Allen wrench install the setscrew into
the head until hand tight.
12. Slowly lower the rod down to the fully retracted position.
13. Pressurize and cycle the cylinder with hydraulic oil
pressure. Test the cylinder at 31,026 kPa/310.2 bar
(4500 psi). Check for proper operation and any leakage.
Make repairs as needed.

CAUTION
Before installing new seals and rings, clean all surfaces
and carefully remove burrs and nicks. Parts displaying
excessive wear or damage should be replaced.
CAUTION
When installing new seals and rings, avoid stretching
seals or scratching the grooved or gland surfaces. Make
sure parts are clean before and during assembly. Make
sure seals and rings are installed in the proper order.
CAUTION
Exercise extreme care when handling the rod. Damage to
the rod surface may cause unnecessary maintenance
and expense. Also, take care to avoid damaging grooved
or gland surfaces or rings or seals during rod insertion.
CAUTION
Do not use air pressure to cycle or pressurize the cylinder.
