DISASSEMBLY
Numbers in parentheses refer to Fig. 1.
WARNING
To prevent personal injury and property
damage, be sure lifting equipment is properly
secured and of adequate capacity to do the job
safely.
1. Ensure clean working conditions, remove plug
from port at the base of cylinder and drain oil from
cylinder assembly into a suitable container.
2. Place cylinder assembly in an upright position,
with piston tube (2) facing up and clamp securely.
3. Remove lock ring (12) from between outer cylinder
(1) and end cap (13).
4. Unscrew end cap (13) and pull end cap (13) and
piston tube (2) out of cylinder body (1) as an
assembly.
5. Position piston tube (2) in a soft-jawed vice and
remove and discard wear ring (5).
Note:
Provide adequate protection to chrome surface
to prevent any damage.
6. Remove retainer (3) and pull end cap (13)
assembly off piston tube (2). Remove and discard
backup ring and 'O' rings (9 & 10) from outer grooves
of end cap (13). Remove and discard wear rings (6),
rod seal (7), nylon ring (11) and wiper seal (8) from
inner grooves of end cap (13).
7. Remove bushing (4) from piston tube (2) and outer
cylinder (1) if they are worn or damaged.
INSPECTION
Numbers in parentheses refer to Fig. 1.
1. Clean all parts of the cylinder with a suitable
solvent and dry with clean, lint-free cloths. Clean all
grooves carefully to remove any foreign material.
2. Check outer cylinder (1) bore and outer diameter
of piston tube (2) for scratches, cracks or other signs
of damage. Remove ridges, nicks and scratches with
a fine stone and re-clean. Replace any components
which cannot be repaired.
3. Inspect piston tube (2) for distortion, cracks or
other defects. Replace piston tube (2) if defective

To prevent personal injury and property
damage, be sure lifting equipment is properly
secured and of adequate capacity to do the job
safely.
1. If necessary, press bushing (4) into eye end of
piston tube (2) and outer cylinder (1).
2. Replace guide ring (3) on piston tube (2) and install
piston tube in outer cylinder (4).
3. Install rod seal (7) into bore of end cap (13) with
the lip pointing towards the internal face of end cap
(13). Install nylon ring (11) behind rod seal (7) in
groove. Install wiper seal (8) and wear rings (6) into
bore of end cap (13).
4. Install back up ring and 'O' rings (9 & 10) in outer
grooves of end cap (13).
5. With the piston tube (2) in a vertical position, guide
