Disassembly (Fig. 55)
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.
1. After removing cylinder, pump oil out of cylinder into
a drain pan by SLOWLY moving rod and piston in and
out of cylinder bore. Plug ports and clean outside of cyl-
inder.
2. Mount cylinder in a vise so piston rod end of cylinder
is tilted up slightly. Do not close vise so firmly that cylin-
der tube could become distorted. Loosen gland.
3. Grasp end of piston rod and usea twisting and pulling
motion to carefully extract piston, piston rod, and head
from cylinder barrel.
4. Securely mountpiston, piston rod, andhead into vise
and remove nut. Remove piston.
IMPORTANT: Do not clamp vise jaws against the
shaft surface. Protect shaft surface before mount-
ing in a vice.
5. Remove all seals and O-rings.
6. Wash part in a safe solvent. Dry parts with com-
pressedair.D O NOT wipe them dry with a cloth or paper
as lint and dirt may remain.
7. Carefully inspect internal surface of barrel for dam-
age (deepscratches, out-of-r ound, etc.). Replace entire
cylinderifbarrelisdamaged.Inspectpiston rod,andpis-
ton for evidence of excessive scoring, pitting, or wear.
Replace any damaged parts.
Assembly (Fig. 55)
1. Use a complete repair k it when rebuilding the cylin-
der. Put a coating of oil on all new seals, and O-rings.
Install the new seal and O-rings.
2. InstallpistonontopistonrodwithO-ringseal(10)and
tighten hex nut.
3. Put a coating of oil on all cylinder parts to ease as-
sembly.
4. Slide piston rod assembly into cylinder tube and
install gland.
