8. Position truck body on sub-frame.
NOTE:
A clearance of at least 2" is required between the truck cab and the closest point on the
truck body.
9. Attach each rear hinge bracket to a long beam by welding all edges where the rear hinge
bracket contacts the long beam.
WARNING
: The saddle tube is oblong, allowing the hoist to slide front to back. This is part of the anti-
kickup design. Before performing the next step, the hoist must be pushed back as far as
possible as shown in Figure 3. Failure to do so will cause the
"anti-kickup device"
to
function improperly, causing damage to the hoist, truck body, and/or other truck
components.
10.
Position a lifting shaft assembly next to each channel long beam. Two 3/8" x 2.5" x 12"
flats are supplied with each hoist. Weld a lift shaft to each channel long beam. Refer to
Figure 5. With the lift shafts secured, slide the lock collars against the lifting tube and
lock them by tightening the set screws. Refer to Figure 4.
11.
Install all grease fittings. For grease fitting locations in the hoist, refer to Figure 10. Torque each
grease fitting to 70 in-lb. Grease all grease fittings on both the hoist and the rear hinge.
12.
Install the body prop. Refer to the
"BODY PROP"
section of this manual.
13.
Install the hydraulic system. Cycle the hoist several times to rid the hydraulic circuit of air.
