GENERAL DESCRIPTION
The tandem rear axle installation (fig. 100) consists of
a rearward rear axle (Eaton Model 30R) and a forward
rear axle (Eaton Model 30D) which carries a single speed
power divider with an inter-axle differential. An air or
vacuum operated shift mechanism is used to lock out the
inter-axle differential to provide positive drive to both
axles when required.
Drive is transmitted from the transmission through a
conventional propeller shaft to the power divider input
shaft (fig. 101). The input shaft supports the inter-axle
differential which transmits equal driving force to two
helical gears, one mated to a gear on the forward rear
axle pinion shaft to drive the forward axle and the other
mated to a gear on the power divider output shaft to
transmit drive force through an inter-axle propeller
shaft to the rearward axle. Both axles drive at all
times, so the inter-axle differential (3rd differential) is
provided to allow differential action between the two
axles. When extra traction is required to move the ve
hicle, the inter-axle differential can be locked out so
equal power can be delivered to each axle. A toggle
switch in the driver's compartment actuates the solenoid-
controlled, vacuum operated, lock-out shift lever at the
axle. The air system is controlled by a lever operated
