Manual

General
The drive train provides two and four wheel drive
includes the engine torque converter trans-
mission drive shaft and front and rear driving axles.
Inching travel is directly related to drive train
functions and will be discussed in this section.
Two & Four Wheel Drive
The drive train is designed to provide two wheel
drive (front axle driving? or four wheel drive (both
front and rear axles driving).
Under certain conditions changing from four wheel
drive to two wheel drive may cause a difference in
the way the machine responds to steering braking
and drive controls. Always be aware of which travel
mode you are using.
There are two ways to disengage rear wheel
drive:
Shift to third gear (rear axle drive is engaged only
in first and second gears)
Disengage rear planetary hubs (refer to Rear
Drive Axle heading in this section).
NOTE: Rear drive axle can also be disengaged in
response to overload in associated electrical circuitry
causing automatic reset type circuit breaker to trip
(open). Breaker will close again in approximately ten
seconds.
Torque Converter
There are no operator controls for the torque
converter. It functions automatically to permit
starting from a standstill in any transmission speed
range.
An oil temperature gage is provided to indicate
Operating temperature of torque converter/trans-
mission. Normal operating temperature is 180 -
200 ° F. (82 - 93 ° C.). If overheating occurs attempt
to lower temperature by traveling in a lower gear. If
necessary stop and allow torque converter to cool
with engine running and gear selector in neutral. Be
sure oil cooler radiator fins are clean.
DRIVE TRAIN
Transmission
The transmission provides three speed ranges for
both forward and reverse travel.
There are three operator controls for the
transmission:
Gear Selector Lever (for 1st 2nd and 3rd gears).
Direction Selector Lever (for forward neutral
and reverse).
Service Brake/Inching Pedal (refer to Inching
Travel heading in this section).
To Operate Transmission:
Release parking brake and hold handler in posi-
tion using service brake.
Move gear selector to appropriate speed range
(1st 2nd or 3rd gear). The gear selector may be
shifted while traveling. When traveling downhill,
use the same gear needed to travel up the hill.
Never shift gear selector or direction
selector to cause a sudden change of
travel speed or direction. Such a change
could cause load to shift or machine to tip
over. Reversing direction while traveling
can also damage transmission.
Move direction selector to forward or reverse
position as required.
Release service brake and depress accelerator to
attain appropriate speed.
Stop handler by releasing accelerator and
applying service brake.
Move direction selector to neutral position.
Apply parking brake.
Front Driving Axle
The front driving axle includes a differential and
planetary drive hubs and is powered by a drive shaft
from the transmission. The service brake/inching
pedal is the only operator control for the front axle
(refer to inching travel heading).
