Assembly
NOTE: Lubricate seals and rings with clean hydraulic oil.
1. Install the backup ring and wiper ring into the retaining
ring (Figure 2-41).
2. Install head retainer ring on rod.
3. Install two new threaded inserts into head.
4. Install the replacement wear rings, buffer seal and deep
Z rod seal in the inside of the head (Figure 2-40). Make
sure the buffer seal’s step is closer to the deep Z rod
seal. Make sure the deep Z rod seal’s rim groove is
closer to the buffer seal.
5. Install the replacement O-ring and the backup ring on
the outside of the head.
6. Install the replacement O-ring and backup rings in the
inside of the piston.
7. Lubricate the rod with clean hydraulic oil.
8. Slide the head, onto the rod.
9. Screw the piston onto the rod tightly. Secure the piston
with the set screw.
10. Install the replacement hydrolock seals on the outside of
the piston. Make sure the “vees” on the two hydrolock
seals point at each other.
11. Lubricate all parts freely with clean hydraulic oil.
12. Remove the cover from the barrel. Insert the rod and
attached parts into the barrel with a slight twisting
motion.
13. Install new gasket material to the cylinder head retainer
ring flange as follows.
a. Clean the barrel and retainer ring with Loctite
cleaning solvent 7070 or similar non- chlorinated
solvent.
b. Apply a light coating of Loctite primer N7649 to both
surfaces. Allow primer to dry for one to two minutes.
Primer must be dry. Mating of parts should occur
within five minutes.
c. Apply gasket material Loctite Master Gasket 518 to
one surface. Partial cure is obtained in four hours,
with full cure in 48 hours.
14. Screw the head retainer ring into the barrel and align
holes in retainer ring with holes in head. Secure the
head retainer ring to the head with two socket head
capscrews. Torque screws to 60 to 65 Nm (44 to 48 lb-
ft).
15. Using a spanner wrench or chain wrench, continue to
screw the retainer ring/head into place in the barrel.
16. Position the holding valve on the cylinder barrel and
secure with four screws and washers.
17. Connect the tubing to the holding valve.
18. Pressurize and cycle the cylinder with hydraulic oil
pressure. Test the cylinder rod side at 241 bar (3500
psi). Test the cylinder piston side at 413 bar (6000 psi).
Check for proper operation and any leakage. Make
repairs as needed.
19. After successful pressure testing, retorque screws
holding retainer ring to head to 60 to 65 Nm (44 to 48 lb-
ft).
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.
