Disassembly
1. Remove oil from lift cylinder into a drain pan by slowly
pumping the cylinder shaft. Plug both ports and clean
the outside of the cylinder.
IMPORTANT: Prevent damage when clamping the
cylinder's barrel into a vise; clamp on the clevis
only. Do not close vise enough to distort the barrel.
2. Mount lift cylinder into a vise.
3. Remove shaft assembly from barrel:
A. For serial numbers below 250999999, remove
collar with a spanner wrench.
B. For serial numbers above 260000000, use a
spanner wrench to 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 opening. Rotate the head counter−clockwise to
remove retaining ring from barrel and head.
C. Extract shaft, head, and piston by carefully twist-
ing and pulling on the shaft.
IMPORTANT: Do not clamp vise jaws against the
shaft surface. Protect shaft surface before mount-
ing in a vise.
4. Mount shaft securely in a vise by clamping on the cle-
vis of the shaft. Remove lock nut and piston from the
shaft. Slide head off the shaft.
5. Remove seal kit components from the piston and
head.
6. Carefully inspect internal surface of barrel for dam-
age (deep scratches, out−of−round, etc.). Replace en-
tire cylinder if barrel is damaged. Inspect shaft, head,
and piston for evidence of excessive scoring, pitting, or
wear. Replace any damaged parts.

ing in a vise.
3. Mount shaft securely in a vise by clamping on the cle-
vis of the shaft.

only. Do not close vise enough to distort the barrel.
5. Mount lift cylinder into a vise. Secure shaft assembly
in barrel:
A. For serial numbers below 250999999, install col-
lar with a spanner wrench.
B. For serial numbers above 260000000, align re-
