DRIVE TRAIN
Description
The drive train consists of the transmission/torque converter
assembly and two drive lines.
The transmission/torque converter is mounted on and driven
by the engine. The torque converter assembly provides for
mounting and driving the two variable displacement pumps
and one gear pump. The transmission is a Range Shift with
six forward speeds and six reverse speeds. The
transmission is controlled electrically by a shift lever/knob
located on the right side of the steering column and an axle
drive mode selector rocker switch located on the steering
wheel console.
The transmission/torque converter oil is cooled by passing
the oil through an externally mounted transmission cooler
that is located on the left side of the crane. An oil filter is
mounted on the left frame rail near the fuel tank.
Three drive lines are used. Two drive lines are connected
between the transmission/torque converter and the front axle
and the other drive line is connected between the
transmission/torque converter and the rear axle.
