Inspect the piston surface, seals and rings 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. (fig. 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.

With the piston and rod removed from the cylinder,

Remove the nut from the rod end. (fig. 16-6)

threads and tap the rod end with a rubber or dead
blow hammer to free the piston from the rod.

Once loose, remove the nut and piston from the
