disassembly.
2.
Pull shaft (1), with all assembled parts, out of
cylinder tube.
NOTE:
Resistance will be felt until piston seal (10) slides
over wire retaining ring groove. Seal is usually damaged
when cylinder is disassembled.

Remove lock nut (12) from end of shaft and slide
piston (8) and cylinder head (6) off shaft.
4.
Remove piston wear ring (11), piston seal (10) and o-
ring (9) from outside grooves on piston (Swing

from inside of cylinder head and o-ring (5) with
backup washer (4) from groove on outside of head.
6.
Clean all parts including cylinder tube, in a suitable
cleaning solvent, then use air pressure to blow any
dirt or excess solvent from all parts.
7.
Examine all parts for wear or damage and replace, if
necessary.
