TRACKS AND SUSPENSION COMPONENTS
The earner moves on its tracks and suspension system. The components and their function are:
Road wheels (1), 10 to each side, carry the weight of the earner.
Road wheel arms (2), five to each side, are splined to individual torsion bars to suspend the carrier.
Torsion bars (3), one for each mad wheel arm, extend the width of the carrier and are firmly anchored to the
hull on the side opposite its road wheel arm.
Tracks (4), on each side, consist of track shoes with rubber pads. Shoes are linked together by pins to form a
continuous rolling surface for the road wheels. Track guides keep track centered on the road wheels.
Sprockets (5), mounted on each final drive, power the tracks.
Idler wheels (6), pushed rearward by track adjusters (7), keep the track under tension.
Shock absorbers (8) at first, second, and fifth wheel positions stabilize the carrier.
