GAS-PARTICULATE FILTER

TM 9-2350-238-20-1

The hydraulic system consists of eight basic subsystems:

The hydraulic power, impact wrench, suspension, and spade subsystems in the hull.

The boom winch, traversing, boom cylinder, and tow winch in the cab.

The gas-particulate filter is used with face masks to protect crew members from toxic gases and

dusty conditions. One filter is mounted in the cab on the boom cylinder and a second filter is

mounted on the floor board in the driver's compartment.

SUSPENSION SYSTEM

The suspension system is a torsion bar, flat-tracked, front-drive type. Ten pairs of roadwheels

support the vehicle and guide the two track assemblies. Each pair of roadwheels is mounted to an

arm and hub assembly that is linked to a torsion bar and lockout cylinder (some vehicles only use

eight lockout cylinders).

Tracks. Each track consists of shoes with a steel body, built in grousers and center guide,

and removable rubber pad. The offset of the roadwheel arms and torsion bars require 76 track

shoes on the right and 75 track shoes on the left.

b. Roadwheels. Rubber-tired, solid disk roadwheels support the vehicle. Each pair of wheels is

secured to the hub by 10 ribbed neck bolts and self-locking nuts. The wheels roll on the tracks, one

on either side of the track center guide. The tracks are driven by the final drive sprockets.
