Greenlee / A Textron Company
38568, 43177, and 43178 Long-Reach Chain Saws
Inner and Outer Tubes
1. Hold the two inner tubes (2 and 3) together, and
slide one O-ring (22) over the tubes, halfway down
the length of the tubes. Turn one of the tubes end
for end, so that the O-ring forms a figure 8 around
the tubes. Slide one O-ring (22) in a figure 8 over
each end of the tubes, pushing the O-ring down
approximately 15.9 cm (6-1/4") from the end of the
inner tubes.
Note: Inner tube (2) is the pressure tube, and should
be marked either with marking tape or with dye on
both ends. Be careful to install the marked tube in
P port of both the motor assembly and the valve
assembly. Improper installation of the inner tubes
will cause the saw to run backwards.
2. Lubricate tips of inner tubes with hydraulic oil to
ease assembly. Press inner tube (3) into the top
(return) port of motor assembly (1). Press inner tube
(2) into the lower (pressure) port of motor assembly,
which is marked P.
3. Press one nut carrier (7) into corresponding holes
in end of outer tube (4). Nut carrier may be glued to
outer tube to hold it in place during assembly. Slide
the outer tube over the inner tubes, with the end
of the outer tube which has small holes for secur-
ing to the handle assembly (8) away from the motor
assembly (1). Place the outer tube into the motor
assembly, aligning the nut carrier under the holes
in the motor assembly. Apply one drop of thread-
locking compound (Loctite 242 or equivalent) to
three oval head machine screws (9). Install screws,
securing outer tube to motor assembly.
4. For proper tool operation, the same inner tube (2)
that was installed in the pressure port of the motor
assembly (1) must be installed in the pressure port
of the handle assembly (8). Lubricate tips of inner
tubes with hydraulic oil to ease assembly. Press
inner tube (3) into the top (return) port of handle
assembly (8). Press inner tube (2) into the lower
(pressure) port, which is marked P.
5. Insert plug (5) and O-ring (6) in outer tube (4) and
install in valve handle (8). Secure with cap screw
(10) and washer (11).
