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.
GAS-PARTICULATE FILTER
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).
a.
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.
