1. Grease Fitting
2. Barrel Assembly
3. Locknut
4. Piston
5. O–Ring
IMPORTANT: To prevent damage when clamping
the cylinder barrel in a vise, clamp only on the pivot
end. Do not clamp the vise jaws against the smooth
shaft surface. Protect the shaft surface before
mounting in the vise.
1. After removing cylinder, pump the oil out of cylinder
into a drain pan by SLOWLY moving piston in and out of
cylinder bore.
2. Plug ports and wash outside of cylinder with cleaning
solvent.
3. Mount the cylinder in a vise so shaft end of cylinder
is tilted up slightly. Do not close the vise so firmly that the
barrel could become distorted. Unscrew collar.
4. Grasp the clevis end of shaft and use a twisting and
pulling motion to carefully extract piston, shaft, and head
from barrel.

scratches, out–of–round, etc.). Inspecthead, shaft and
piston for evidence of excessive scoring, pitting, or
wear. Replace any defective parts.
9. Put a light coating of hydraulic oil on all other new
seals and backup washers. Install new seals and back-
up washers. Install head onto piston rod. Install piston
onto shaft and tighten lock nut.
