3. Using a spanner wrench, rotate head clockwise until
the edge of the retaining ring appears in the barrel open-
ing. Insert a screwdriver under the beveled edge of the
retaining ring to start the retaining ring through the open-
ing.Rotatetheheadcounter-clockwisetoremovere-
taining ring from barrel and head.
4. Remove plugs from ports. Extract shaft, head and
piston by carefully twisting and pulling on the shaft.
IMPORTANT: Do not clamp vise jaws against the
shaft surface. Clamp on the clevis ONLY.
5. Mount shaft securely in a vise by clamping on the cle-
vis of the shaft. Remove lock nut and piston from the
shaft. Carefully slide head off the shaft.
6. Taking care to not scratch or damage the piston, re-
move wear ring, BP seal and O- ring from the piston.
7. Taking care to not scratch or damage the head, re-
move O- ring, back- up washer, dust seal and BS seal
from the head.
8. Discard removed seals and O- rings.
Inspection
CAUTION
Use eye protection such as goggles when using
compressed air to clean lift cylinder compo-
nents.
1. Wash all lift cylinder components in solvent. Dry
parts with compressed air.
2. Inspect internal surface of barrel for deep scratches,
out- of- roundness and bending.
3. Inspect head, shaft and piston for excessive pitting,
scoring and wear.
4. Replace lift cylinder if internal components are found
to be worn or damaged.
Assembly (Fig. 76)
1. Make sure all lift cylinder parts are clean before as-
sembly.
2. Coat new O- rings, back- up washer and o ther seals
with clean hydraulic oil.
A. Carefully install wear ring, BP seal and O- ring to
the piston.
B. Carefully install back- up washer, O- ring, dust
seal and BS seal to the head.
IMPORTANT: Do not clamp v ise jaws against the
shaft surface. Clamp on the clevis ONLY.
3. Mount shaft securely in a vise by clamping on the cle-
vis of the shaft.
A. Coat shaft with clean hydraulic oil.
B. Slideheadassemblyontotheshaft.
C. Install piston assembly onto the shaft and secure
with lock nut. Torque lock nut 40 ft- lb (54 N- m).
D. Remove shaft assembly from the vise.
IMPORTANT: Prevent damage when clamping the
hydraulic cylinder into a vise; clamp on the clevis
end of the barrel ONLY.
4. Mount barrel securely in a vise by clamping on the
clevis end of the barrel.
IMPORTANT: When installing the head into the bar -
rel, pay careful attention to the retaining ring slot in
the barrel to insure that the piston and head seals do
not lodge in the slot.
5. Coat all internal parts with a light coat of clean hy-
draulic oil. Slide piston, shaft and head assembly into
the barrel being careful not to damage the seals.
6. Secure head in barrel by installing retaining ring.
A. Align retaining ring hole in the head with the ac-
cess slot in the barrel.
B. Insert the retaining ring hook into the hole and ro-
