COMPONENT DESCRIPTION AND SPECIFICATIONS ENGINE SERVICE BRAKE SYSTEM The 210M HAULPAK ® is powered by a Cum- mins KTTA--19C diesel engine. The truck is capable of speeds up to 35 MPH (56.7 km/h). 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. TRANSMISSION The diesel engine drives a remote-mounted Allison CLT-6062 transmission incorporating a TC683 torque converter. The transmission has six speeds "Forward" and one "Reverse" and uses Allison Transmission Electronic Control (ATEC) for complete automatic shift sequencing.
By moving the operator’s Range Selector in the cab, the operator may select "R" for Reverse, "N" for Neutral or any one of six Forward driving ranges. Automatic Emergency Braking is provided if system pressure falls below a preset value. All functioning wheel brakes will be automat- ically applied by accumulators. POWER STEERING The HAULPAK ® Truck is equipped with an orbital power steering system mounted un- der the cab floor with noise and vibration isolators. Emergency power to safely steer the truck while stopping is provided automat- ically by an accumulator. The Range Selector is an electronic-me- chanical control unit.
Each position (R,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 up- shifts are permitted. INSTRUMENTS The instrument panel located in the cab pro- vides the operator easy identification of all instruments and gauges which are neces- sary to control the truck and monitor the truck’s operating systems.
DYNAMIC RETARDING SUSPENSION HYDRAIR ® II suspension cylinders located at each wheel provide a smooth and comfort- able ride for the operator and dampens shock loads to the chassis during loading. Dynamic retarding is actuated by depressing the operator’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 modulated and should be used to slow the truck during normal truck operation, to con- trol 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.
FINAL DRIVE Planetary Final Drive has full floating axle shafts and a plug-in differential carrier assem- bly. HB1017 Component Description and Specifications HB1-1
