Note: Shim ALL upper rear wear pads as needed to
maintain a total maximum gap of .06" (1,5 mm) at the
rear of the pads and maintain a total minimum gap of
.07 to.13" (1,8 to 3,3 mm) in the vertical direction.
6. Install the inner boom upper wear pads:
a. Apply Loctite
®
242 threadlocker to the threads of
the capscrews (1), saved, for the upper wear
pads (2).
b. Place the wear pad shims (3), saved, and wear
pad spacer (4) onto the top of the boom with the
offset toward the outside of the boom. Line up
the holes in the shims, spacer and wear pad with
the holes in the boom. Place the wear pad
inserts (5), saved, into the cavities in the wear
pad. Be sure the inserts are seated completely in
the cavities.
c. Insert a capscrew with a lockwasher (6), saved,
through each of the mounting holes in the top of
the inner boom. Be careful not to push the wear
pad inserts out of the wear pads.
d. Torque all wear pad mounting capscrews to
31 ±3 lb-ft (42 ±4 Nm).
e. Fill each cavity with a good grade of lithium-
based EP grease.
7. Lay the inner boom extend chain (7) on the top of the
inner boom with the threaded clevis end (8) toward
the rear of the boom.
8. Coat the threads on the clevis (8) with multi-purpose
grease and insert the clevis through the hole in the
anchor plate.
9. Install a flat washer (9), saved, and a new elastic
locknut (10) onto the clevis. Tighten the elastic
locknut far enough so the threads are even with the
top of the locknut.
10. Fold the hose carrier assembly (11) in half and slide
into the inner boom. Be careful while folding the
hose carrier in half.
IMPORTANT: The hose carrier only folds one way;
DO NOT force it. DO NOT twist the hose carrier while
folding.
11. Ensure the “female” ends (12) of the hoses are on
the bottom, and carefully slide the folded hose
carrier into the inner boom (13). Guide the hose
carrier assembly between the channels of the hose
channel assembly.
