5.5-2 Cylinder Disassembly
1 Clamp the cylinder in a soft-jawed vise. Clamp lightly
on the base end only.
2 Position the cylinder rod in the fully extended position.
Remove the spiral snap ring from the retainer. See the
illustration below.
3 Tap the retainer into the shell approximately 2 in.
(50 mm). Remove the retaining ring by prying one end
up and working the ring out of the groove.
Service Tool Kit 674424 includes two double-ended
brass tools that make seal and ring removal easy and
won’t damage the cylinder components with dents or
scratches.
CAUTION: Do not scratch the cylinder bore.
4 Remove the rod assembly from the cylinder. See the
illustration below.
5 Clamp the rod assembly in a soft-jawed vise or between
two blocks of wood. Never clamp directly on the rod
sealing surface. Remove the nut fastening the piston to
the rod. Remove the piston and retainer.
6 Place the piston or retainer in the vise to remove the
seals. Pry the seals up with a brass tool. Cut the seals
to remove.
CAUTION: Do not scratch the seal grooves.
5.5-3 Cylinder Inspection
• Inspect all components for nicks or burrs. Minor nicks
or burrs can be removed with 400 grit emery cloth.
NOTE: Minor nicks are those that will not bypass oil
under pressure. If nicks cannot be removed with emery
cloth, replace the part.
• Inspect the outside of the shell for deformities that could
weaken the shell’s performance when under pressure.
Replace if necessary.
