4. The front bottom pad may be removed by first
removing the top pads. Lower the gooseneck
end of the inner boom to the ground until the
intermediate boom raises up to provide
clearance for removing the bottom pad.
5. Inspect the wear pads removed as described
in the preceding
IMPORTANT notice.
c. Outer Boom Wear Pads (Fig. 3.9)
1. All outer wear pads can be removed working
at the front of the boom.
2. The front bottom pad may be removed by first
removing the top pads. Lower the gooseneck
end of the inner boom to the ground until the
intermediate boom raises up, thereby provid-
ing clearance for removing the bottom pad.
3. Inspect the wear pads removed as described
in the preceding
IMPORTANT notice.
IMPORTANT: Inspect the pads as follows:
• Replace wear pads that are less than 0.375"
(9,5 mm) thick.
• Each boom wear pad is manufactured with a
convenient wear pad indicator. This is the
angled cut at each end of all wear pads,
Fig. 3.16. The total thickness of a new wear
pad is .625" (15,9 mm), the angled cut will
provide a total wear thickness of .25"
(6,4 mm). This will leave approximately
.375" (9,5 mm) of total unused material. The
wear pads must never be worn past the
angled cut indicator because the metal pad
insert that holds the pads in place will begin
to wear into the boom pad sliding surfaces.
If pads are worn past this point it will cause
gouging on boom plate surfaces which will
result in premature wear of any new wear
pads installed if the surfaces are not ground
smooth again.
• When you install a wear pad on one side
(including top or bottom) of boom, replace
the corresponding wear pad on the other
side of the boom. Usually shimming will
remain the same when installing new wear
pads on corresponding sides of the boom.
• Apply Loctite ® 242 to all wear pad screws
and torque them to 31 lb-ft (42 Nm).
a. Inner Boom Wear Pads (Fig. 3.3)
1. All inner boom wear pads can be removed by
working through the rear boom cover opening.
2. The bottom pad may be removed by first
removing the top pads. Use a wooden wedge
between the inner and intermediate boom to
provide clearance for removing the bottom
pad.
3. Inspect the wear pads removed as described
in the preceding
IMPORTANT notice.
b. Intermediate Boom Wear Pads
(Fig. 3.5 and 3.6)
1. The rear wear pads can be removed by
working through the rear boom cover opening.
2. The rear bottom pad may be removed by first
removing the top pads, by using a wooden
wedge between the inner and intermediate
boom, thereby providing clearance for remov-
ing the bottom pad.
3. Front pads can be removed at the front of the
boom.
3.1.9 Hose Tensioning
100 Hour Intervals
Adjust grille tilt cylinder hose or auxiliary hydraulic
hose tension whenever the boom is disassem-
bled, a hose is changed, or whenever proper hose
adjustment is in question. Check hose tension as
part of general maintenance every 100 hours.
IMPORTANT: Before you begin tensioning the
hoses make sure that the hoses are not twisted
within the boom. Keep the hose manufacturers
marking in line as a guide.
1. Park forklift on level surface, engage park lock
and fully retract and level the boom.
2. Remove the rear boom cover, Fig. 3.1.
3. If the vehicle has auxilliary hydraulics there
will be four hoses in hose clamps, Fig. 3.17b,
with the auxilliary hose clamps stacked on top
of the grille tilt cylinder hose clamps,
Fig. 3.17a. Remove the capscrews and hose
clamps, holding upper hoses in place,
Fig. 3.17b, and move aside to gain access to
the lower capscrews and hose clamps.
4. Loosen capscrews securing the hose clamps
to the inner boom, Fig. 3.17a or Fig. 3.17b.
5. Manually remove all hose slack between the
pulley and the inner boom hose clamps and
the pulley and the outer boom tubes. Pull the
hoses through the hose clamps, towards the
front of the boom, until there is 180° of hose in
contact with the pulley.
