IMPORTANT: To prevent damage to rod or barrel,
clamp vise on pivot ends only. DO NOT clamp

1. After removing the cylinder, pump oil out of cylinder
into a drain pan by SLOWLY moving piston in and out of
cylinder bore.
2. Plug the ports and clean the outside of the cylinder.
3. Mount cylinder in a vise so rod end of cylinder is tilted
up slightly. Do not close the vise so firmly that the cylin-
der barrel could become distorted.
4. Use a spanner wrench to unscrew (counterclock-
wise) head from barrel (Fig. 20).
5. Grasp large end of piston rod and use a twisting and
pulling motion to carefully extract piston, rod, and head
from cylinder tube.
6. Securely mount piston, rod, and head into vise so
large nut is easily accessible for removal. Remove nut
by turning it counterclockwise.
7. Remove piston. Slide head off of piston rod.
