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 oil out of cylinder into
a drain pan by SLOWLY moving piston in and out of cyl-
inder bore.
2. Plug ports and wash outside of cylinder with cleaning
solvent.
3. Mount 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 clevis end of shaft and use a twisting and pull-
ing motion to carefully extract piston, shaft, and head
from barrel.

(deep scratches, out–of–round, etc.). Inspect head,
shaft and piston for evidence of excessive scoring, pit-
ting, or wear. Replace any worn or damaged parts.

seals and backup washers. Install the new seals and
backup washers. Install head onto piston rod. Install pis-
ton onto the shaft and tighten lock nut.
