Installation
Inspect all lifting devices. Slings, chains, and/or
cables used for lifting components must be in-
spected daily for serviceable condition. Refer to
the manufacturer's manual for correct capacities
and safety procedures when lifting components.
Replace any questionable items.
Slings, chains, and/or cables used for lifting com-
ponents must be rated to supply a safety factor of
approximately 2X the weight being lifted.
When in doubt as to the weight of components or
any assembly procedure, contact the Komatsu
area representative for further information.
Lifting eyes and hooks should be fabricated from
the proper materials and rated to lift the load being
placed on them.
Never stand beneath a suspended load. Use of guy
ropes are recommended for guiding and position-
ing a suspended load.
Before raising or lifting the body, be sure there is
adequate clearance between the body and over-
head structures or electric power lines.
Be sure that the lifting device is rated for at least a
45 ton capacity.

the inside. A minimum of 1 shim is required at the
outside end of both frame pivots.
3. If not already installed, install retainer (1) and
capscrews (2) to hold bushing (12) in place.
Tighten capscrews to 40 ft.lbs. (55 N.m) torque.
4. Align the hole in pivot pin (6) with capscrew hole
in pin retainer (part of body pivot ear, 7) and push
the pivot pin through the shims (9), frame pivot
(10), and into the pivot bushings (8, 12) in each
side of the body pivot.
5. Install capscrew (4) through each pin and tighten
the nuts (5) to 2028 ft.lbs. (2750 N.m) torque.
6. Align hoist cylinder upper mounting eye bushings
with the hole through the body, align retaining
capscrew (4, Figure 3-2) hole and install the pin.
