SECTION 9
SERVICE AND REPAIR
TELESCOPIC CYLINDER PACKING
REPLACEMENT
1. Drain the hydraulic fluid from the cylinder. Clean
the outside of the cylinder prior to working on it to
prevent contamination from entering the cylinder.
Secure the cylinder to the floor or a workbench in a
vertical position (rod end up).
2. Remove the setscrew (1) and plastic plug (2) from
the head nut.
3. Remove the smallest head nut (3) using a strap or
chain wrench. If the tube turns with the head nut,
tighten the next head nut slightly.
4. Repeat steps 2 and 3 to remove each head nut.
5. Using a suitable lifting device attached to the rod
eye (5), pull up on the tube. The packing (4) should
come out as the tube is raised. If it does not, clean
off a section of the tube and wrap masking tape
around it. Lower the wrapped section of tube down
into the packing and then lift the tube once again.
6. When removing the packing from succeeding larg-
er stages, replace the head nut (3) on the stage
directly above the section you need access to.
Wrap a strap under the head nut and use it to lift
the tube.
7. Prior to installing new packing (4), clean the area
thoroughly and lubricate the new packing set inside
and out with an all-purpose grease.
8. If the proper size packing driver is not available, the
packing may be installed by turning the head nut
over, placing it on the packing and using a rubber
or plastic mallet, tap the packing into place.
9. Replace all of the head nuts (3) being careful not to
overtighten.
10. Replace the plastic plug (2) and setscrew (3).
