The transmission supplies one reverse and five
forward speeds.
h. Transmission Power Takeoff (Fig. 2-12).
All trucks except dump truck, have
single-ended transmission power takeoff units.
The dump truck has a double-ended unit.
(1) Single-ended unit is a two-speed-and-reverse drive, mounted on the left side of
the transmission. The power takeoff supplies power to the front winch. The power takeoff
is controlled by a shifting lever in the cab.
(2) Double-ended unit is mounted on the left side of the transmission. The forward
output shaft is a two-speed-and-reverse drive to the front winch with shifting lever in the
cab. The rear accessory drive shaft drives the hydraulic hoist pump on dump trucks and
