(8.1 L) Fuel consumption, typical ................................................................4.6 to 7.0 gal./hr. (17.4 to 26.5 L/h) Maximum net torque .......................................................................601 lb.-ft. (815 Nm) @ 1,300 rpm Lubrication ......................................................................................pressure system with full-flow spin-on filter and oil-to-water cooler Air cleaner.......................................................................................dual stage dry type with safety element, precleaner, and underhood restriction indicator Electrical system .............................................................................24 volt with 45-amp alternator Cooling fan ......................................................................................blower Transmission automatic, dual-path, hydrostatic drive; load sensing feature automatically adjusts speed and power to match changing load conditions; each individually controlled track is powered by a variable displace- ment piston pump and motor combination; travel speeds (forward and reverse) infinite to 6.8 mph (0 to 11 km/h); ground-speed selection buttons on single-lever steering and direction control; inde- pendently selectable reverse speed ratios 80%, 100%, 115%, or 130% of forward ground speed; decelerator pedal controls ground speed to dead stop Final Drives double-reduction, planetary final drives transfer torque loads over three gear sets; mounted independently of track frames and dozer push frames for isolation from shock loads Steering single-lever steering, direction, and ground-speed control provides smooth metered turns; full power turns, counterrotation, and infinitely variable track speeds provide unlimited maneuverability and optimal control; hydrostatic steering system eliminates steering clutches and brakes Brakes hydrostatic (dynamic) braking stops machine when the direction/steering control lever is moved to neutral, the decelerator is depressed to the end of travel, or the brake pedal is depressed Automatic Parking Brake this safety feature engages wet, multiple-disk brakes automatically whenever the engine stops, the operator applies the brake pedal, or the neutral start lever lock is in stop position; machine cannot be operated with brake applied Hydraulic System System type ....................................................................................open center Pressure, system relief ....................................................................2,250 psi (15 514 kPa) Pump type.......................................................................................gear Flow ................................................................................................44 gpm (166 L/min.) @ 2,100 rpm Filter, return oil ................................................................................10 micron Control ............................................................................................standard – T-bar, two function / with All-Hydraulic (PAT) dozer blade – T-bar, three function Cylinders .........................................................................................heat-treated, chrome-plated, polished cylinder rods with hardened steel (replaceable bushings) pivot pins Cooling ............................................................................................oil-to-air heat exchanger Capacities (U.S.) 850C LT 850C WT 850C WXLT 850C LGP Fuel tank with lockable cap.............................................................92 gal.
