MAJOR COMPONENTS AND SPECIFICATIONS
ENGINE
®
The 210M HAULPAK
Truck is powered by a Cummins
QSK--19C diesel engine. It is capable of speeds up to
35 MPH (56.7 km/h).
TRANSMISSION
The diesel engine drives a remote-mounted Allison
CLT-6063 transmission incorporating a TC683 torque
converter. The transmission has six "Forward" speeds
and two "Reverse" speeds and uses Allison Transmis-
sion Electronic Control (ATEC) for complete automatic
shift sequencing.
The operator may select "R1" or "R2" for Reverse, "N"
for Neutral, or any one of the six Forward driving ranges
by using the Transmission Range Selector. Each posi-
tion (R2, R1, N, D, 5, 4, 3, 2, 1) is selected by releasing
a range locking mechanism on the lever and choosing
the desired range. "D" will permit completely automatic
up and down shifts through all six ranges. "5" will limit
upshifts to 5th range only. "4" will limit upshifts to 4th
range only. "3" will limit upshifts to 3rd range only. "2"
will limit upshifts to 2nd range only. "1" is a first range
hold position and no upshifts are permitted.
"R1" or "R2" REVERSE position is used to back the
truck. "R1" position should be used for normal reverse
operation. This range selection utilizes the standard
5.12:1 gear reduction ratio. "R2" position may be used
for job operations that would benefit from a higher
speed reverse operation. This range selection utilizes
a 3.43:1 gear reduction ratio.
FINAL DRIVE
The Planetary Final Drive has full floating axle shafts
and a plug-in differential carrier assembly.
SERVICE BRAKE SYSTEM
The service brakes are controlled by an all hydraulic
actuation system. Depressing the service brake pedal
actuates front dry disc brakes and rear wet disc brakes.
Automatic Emergency Braking is provided if system
pressure falls below a preset value. All functioning
wheel brakes will be automatically applied by accumu-
lators.
DYNAMIC RETARDING
Dynamic retarding is actuated by depressing the op-
erator's retarder pedal which applies oil-cooled, rear
mounted, wet disc brakes only; the front brakes are not
applied.
Application of the retarder pedal may be fully modu-
lated and should be used to slow the truck during
normal truck operation, to control speed coming down
a grade or to make non-emergency stops. Use of the
retarder pedal saves wear on the front brakes and
provides better steering control.
POWER STEERING
®
The HAULPAK
Truck is equipped with an orbital
power steering system mounted under the cab floor
with noise and vibration isolators. An accumulator
automatically provides emergency power to safely
steer the truck while stopping.
INSTRUMENTS
The cab instrument panel displays for the operator all
switches and gauges which are necessary to safely
control the truck and monitor the truck's operating
systems.
SUSPENSION
®
HYDRAIR
II suspension cylinders located at each
wheel provide a smooth and comfortable ride for the
operator and dampens shock loads to the chassis
during loading.
