Use an open end or pipe wrench to turn and
remove the end gland. (figure 16-2)

Use a pry bar or similar device to pull the rod and
piston from the cylinder. (figure 16-3)

Inspect the piston surface, seals and ring for wear
or damage. If any component appears to be dam-
aged in any way, replace it. When inspecting the
piston surface, look for scratches. If any are pres-
ent that are deep enough to catch with your finger-
nail, the piston should be replaced. (figure 16-4)
Note:
Seal imperfections or scratches on the piston, bore or
rod or will cause internal/external leakage and impaired func-
tion. Defective components must be repaired or replaced.
7.
With the piston and rod removed from the cylinder,
inspect the cylinder bore for scratches or other
damage. If any are present that are deep enough
to catch with your fingernail, the cylinder tube
weldment should be replaced. (figure 16-5)
8.
Remove the nut from the rod end. (figure 16-6)
9.
Support the piston loosely from the underside (fig-
ure 16-7), thread the nut partially on to protect the
threads and tap the rod end with a rubber or dead
blow hammer to free the piston from the rod.
10.
Once loose, remove the nut and piston from the
rod.
