each corner of the CBC. The base (19) at the bottom of the lifting/locking assembly (15) is positioned over

the corner fitting pulley assembly (18) on the lower section. Pins (20) protruding from the base (19) of the

lifting/locking assembly (15) are aligned with slots located in the interlocking extrusion at the corner fitting

pulley assembly (18).

The handle (17) is then swung up and locked into position using the hairpin cotter (16) removed earlier.

The Cargo Bed Cover is now in its fully extended and locked position. The lower personnel door panel

(11) is stored in an area on the inside roof surface when the CBC is in the retracted mode. The lower

panel is installed when the CBC is fully extended.

Once the CBC is in its fully extended and operational position, the lower section (11) of the personnel door

must have its hinge relocated from its stowed position before installing the lower door section (11) below

the upper section (10) of the personnel door using three hand knob screws (21), completing the personnel

door assembly (22). A door hold-open device (23) is provided on the outside of the personnel door to lock

the door into an open position if desired.

Ventilation ports (24) are provided on the left and right side walls of the CBC permitting air to enter the

interior.

Signal and power entry ports (25) are provided on the sidewalls of the CBC that permit power and signal

cables to enter and/or exit from the CBC. Block out panels on the inside of the CBC are provided that

allow the ports to be covered when not in use.

Three roof access steps (26) are located to the right of the personnel door at the rear of the CBC to

provide a foothold for personnel climbing to the roof of the Cargo Bed Cover. A handhold (27) is installed

on the top of the CBC to assist personnel in climbing onto the roof.

Lift rings (28) are provided on each corner of the roof to permit the CBC to be lifted into position or

removed from the bed of the M35A2, 2 1/2 T Cargo Truck, M1078, 2 1/2 T LMTV, or M1082, 2 1/2 T

LMTV Trailer.
