• Remove the seal (H18) from groove on
piston (H17).
• Clean all exposed components with a
mild solvent.
• Inspect all parts for damage.
• Piston rod bushing (H11) can remain
assembled to piston rod. It should be
disassembled and replaced only if worn
or damaged.
5.3.3 Cylinder Bushing Removal -
S1500X, S3000X, S6000X and
S11000X only (Fig. 22, 23 and 24)
NOTICE
Remove the cylinder bushing
components (H13, H14, H15 and H16) as
described in the following procedure only
if there is hydraulic fluid leakage in the
piston head area.
• To allow access, remove all piston
components as described in Section
5.3.2.
NOTICE
In the next step, the tapered end
of the retaining ring (H16) must be aligned
with the slot in the cylinder bushing (H15)
to allow a seal pick tool to fit behind the
retaining ring. If needed, use a screwdriver
to rotate the ring as required. See Fig. 23.
• Press the retaining ring (H16) radially
inward using a flat-head screwdriver.
• Lift the retaining ring (H16) away from
the groove and out of the bore using a
seal pick.
• Remove the cylinder bushing (H15) by
placing a suitable drift through the front
of the tool, and pushing against the
bushing.
• Remove seal (H14) from groove on
inside of bushing (H15).
• Remove O-ring (H13) from groove on
outside of bushing (H15).
NOTICE
When the bushing (H15) is
removed, the O-ring (H13) will be
damaged and will need to be replaced.
Replacement of seal (H14) is also strongly
recommended.
5.3.4 - Non Destructive Testing
• Perform magnetic particle inspection on
the following components:
- Housing (Fig. 18 & 22 item H2)
- Ratchet Lever (Fig. 18 & 22, item H4)
- Drive Shoe (Fig. 18, item H7)
- Ratchet (Fig. 18, item H8)
- Drive Shaft (Fig. 18, item H9)
- Piston Rod (Fig. 22, item H12)
- Reaction Arm (Fig. 26, item J2)
NOTICE
Removal of the cylinder
bushing (H15) is necessary only if there is
hydraulic fluid leakage in the piston head
area. Cylinder bushing components (items
H13 through H16) can remain installed
during magnetic particle inspection.
However, to avoid possible seal damage,
be careful that inspection fluid does not
contact the seals.
