General
A drive shaft, connected to the transmission output shaft, transfers power to the rear axle assembly. The
rear axle assembly is a double reduction unit with three inboard planetary gears and integral, multi
- disc
hydraulic brakes. The rear axle housing is mounted directly to the rear frame module. A Super Max Trac®
torque proportioning differential transfers power to each axle shaft.
Attached to each side of the rear axle housing is a tandem drive. The axle extends into the tandem drive and
a double sprocket is attached to the end of each axle. A double chain is driven by the axle sprocket with
each side of the chain driving one wheel. The tandem drive is sealed to allow the chain to operate in an oil
bath.
Each tandem drive is allowed to rotate freely around the axle, limited by frame stops. The tandem drives are
the same on each side.
