RT9130E-2 SERVICE MANUAL POWER TRAIN
DRIVE TRAIN
Description
The drive train consists of the Torque Converter,
Transmission, and four Drive Shafts.
The torque converter is mounted on and driven by the
engine. The torque converter provides for mounting and
driving hydraulic pumps No. 1, No. 2, and No. 3.
The transmission is a Spicer R36000 Series (R36626)
powershift with six forward speeds and three 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
left side of the front console.
The torque converter and transmission oil is cooled by
passing the oil through an externally mounted transmission
cooler. The cooler is mounted on the right side of the
machine in front of the hydraulic reservoir. An oil filter is
located on the left side of the frame behind the fuel tank.
Four drive shafts are used. One drive shaft is connected
between the torque converter and the transmission. The
other three drive shafts are connected between the
transmission and the front and rear axles.
Maintenance
Drive Lines
Removal
1. Support the drive shaft being removed so it does not fall
when disconnected. If removing the coupling shaft or the
front slip shaft, support the other shaft also.
2. If removing the coupling shaft, free its bearing from its
bracket by removing two bolts, two nuts, and four
washers.
3. Remove the bolts from the bearing cap on each end of
the drive shaft. Note the lengths of the bolts and if they
have lockwashers. Remove the drive shaft.
Installation
1. For any drive shaft which has mating marks (arrows),
align these mating marks to ensure proper phasing of
coupler yokes.
2. Position the drive shaft between the couplers on the two
components it is joining.
3. For the coupling shaft, secure its bearing to its bracket
with two bolts, two nuts, and four washers.
4. Secure the drive shaft to the coupler with bolts. Torque
all bolts according to Fasteners and Torque Values,
page 1-18.
Lubrication
The drive line slip joints require lubrication. Refer to
Lubrication, page 9-1.
CAUTION
Do not disassemble drive lines when removing them from
the crane. Dirt can enter the spline and cannot be purged.
In addition, the drive lines are assembled in a specific
orientation when manufactured and can easily be
incorrectly reassembled.
