Displacement .........................................................276 cu. in. (4.52 L)  
Fuel consumption, typical.......................................1.7 to 2.6 gal./hr. (6.4 to 9.8 L/h)  
Maximum net torque..............................................255 lb.-ft. (344 Nm) @ 1,200 rpm  
Lubrication.............................................................pressure system with full-flow spin-on filter and oil-to-water cooler  
276 cu. in. (4.52 L)  
1.7 to 2.6 gal./hr. (6.4 to 9.8 L/h)

Air cleaner..............................................................dual stage dry type with safety element, precleaner, and dash-mounted restriction indicator  
Electrical system....................................................12 volt with 65-amp alternator  
Cooling fan.............................................................blower  
Transmission  
Dual-path, electronic-controlled, hydrostatic drive; load-sensing feature automatically adjusts speed and power to match changing load conditions; each individual track is  
powered by a variable-displacement piston pump and two-speed motor combination; decelerator controls speed from holding to 5.0 mph (8.0 km/h)  
Travel speeds (infinitely variable)  
Forward and reverse ........................................0 to 5.0 mph (0 to 8.0 km/h)  
Final Drives  
Heavy-duty triple-reduction final drives attach directly to the mainframe and are isolated from track frame and dozer frame loads  
Steering  
Single-lever steering, direction control, and counterrotation; full power turns and infinitely variable track speeds provide unlimited maneuverability and optimum control;  
hydrostatic steering eliminates steering clutches and brakes  
Brakes  
Hydrostatic (dynamic) braking stops the machine whenever the direction-control lever is moved to neutral, whenever the decelerator is depressed to the end of travel, or  
whenever the brake pedal is depressed  
Automatic Park Brake  
Exclusive safety feature engages wet, multiple-disc brakes automatically whenever the engine stops, whenever the operator applies the brake pedal, or whenever the neutral  
start lever lock is in the stop position; machine cannot be driven with brake applied, reducing wear out or need for adjustment  
Hydraulic System  
System...................................................................open center  
Pressure, main relief ..............................................3,000 psi (20 685 kPa)  
Pump .....................................................................gear  
Flow.......................................................................15 gpm (56.8 L/min.) @ 2,200 rpm  
Filter, return oil.......................................................10 micron
