6. Spray the wear pad pathways on the inside of the
outer boom, inside of the intermediate boom and the
underside of the intermediate boom with LPS3 or
equivalent.
7. Before installing the intermediate boom into the
outer boom, place a string (heavy enough to pull the
Attachment Tilt and auxiliary hydraulic hoses) down
the inside of the outer boom. Allow the string to hang
out the rear of the boom. Pull the other end out the
opening on the left side of the boom where the
hoses will exit the boom. Place one string for each
hose in the boom. Position the strings all the way to
the left side of the outer boom.
8. Use the hoist and slings to slightly lift the front of the
intermediate boom to allow installation of the center
wear pad:
a. Fill all wear pad cavities with a good grade of
lithium-based EP grease.
b. Slide the center wear pad mount (1) into the
outer boom with the wear pad offset toward the
right side. Line up the threaded holes in the wear
pad mount with the holes in the bottom of the
outer boom.
c. Apply Loctite
®
242 threadlocker to the threads of
the capscrews (2), saved. Secure the wear pad
mount to the outer boom with the capscrews (2)
and lockwashers (3), saved.
d. Torque all wear pad mounting capscrews to
31 ±3 lb-ft (42 ±4 Nm).
9. Remove the slings and the hoist from the
intermediate boom.
10. Install the side wear pads to the outer boom:
a. Slide the intermediate boom over to one side as
far as it will go, to allow wear pad installation.
b. Place the wear pad inserts (4), saved, into the
cavities of the side wear pads (5), saved. Place
the shims (6), saved, onto the wear pad and align
the holes.
c. Fill all wear pad cavities with a good grade of
lithium-based EP grease.
d. Apply Loctite
®
242 threadlocker to the threads of
the capscrews (7), saved. Slide the wear pad
with shims in between the intermediate boom
and the outer boom with the offset of each wear
pad away from the center. Align the holes and
secure in place with the capscrews (7),
lockwashers (8), saved, and flat washers (9),
saved. Be careful not to push the wear pad
inserts out of the wear pads.
