the inner boom with LPS3 or equivalent.
24. Lift the inner boom. While guiding the hoses into the
secondary intermediate boom, carefully slide the
inner boom into the front of the secondary
intermediate boom.
25. Have a second person guide the “male” ends of the
four hoses from the hose carrier into the secondary
intermediate boom. Have the second person pull the
hoses out the rear of the boom as the inner boom is
being inserted.

the hose carrier (12). Inside the inner boom, pull the
hose carrier out enough to gain access to the
mounting pivot on the end of the carrier.

support (11) on the right side, line up the four holes
in the top plate with the holes in the pivot mount of
the hose carrier (12).

carrier pivot mount and the support bracket. Secure
in place with new elastic locknuts (14). Tighten
securely.

holding the lower wear pad to the bottom of the
secondary intermediate boom.
30. Apply Loctite
®
242 threadlocker to the threads of the
capscrews. Line up the holes in the lower mounting
plate on the hose carrier support (17) and reinsert
the capscrews and lockwashers. Be careful not to
push the wear pad inserts out of the wear pads.
31. Torque all wear pad mounting capscrews to
31 ±3 lb-ft (42 ±4 Nm).
32. Place the retract chain (18) up around the retract
chain sheave on the left side of the boom. Stretch
the chain forward and place the clevis between the
two anchor plates (19). Line up the hole in the clevis
with the anchor plate hole location recorded during
removal.
Note: ALWAYS replace elastic locknuts with new elastic
locknuts to help ensure proper fastening.
33. Insert the shoulder bolt (20), saved, from the top
down and secure in place with a new elastic
locknut (21). Tighten the locknut securely.
