Foot pedals operate additlonal functions such as extendible Stick and auxiliary lines. 6 Hydraulics Caterpillar sets the standard in power and precision with load- sensing hydraulics. Load-Sensing Hydraulic System. The variable displacement piston pump and flow-sharing hydraulic valves sense work demand and adjust flow and pressure for increased productivity. Load-sensing hydraulics deliver: • • • • • Maximum lift and dig forces at any engine RPM Cooler hydraulic system Better fuel efficiency Quieter operation Reduced wear on components Hydraulic Pump.

The variable displacement piston pump improves implement response and Speed while Still providing high forces at any engine speed. A supplemental gear pump provides increased flow and responsiveness. Torque Limiter Control. The pump torque limiter control manages distribution of engine power to the hydraulic system and drive train. E-Series improvements produce more aggressive backhoe digging and tronger truck loading performance. Flow-Sharing Hydraulic Valves. Technology leveraged from Cat Hydraulic Excavators, new flowsharing hydraulic valves automatically distribute flow to optimize multifunction implement performance. Closed-center implement valves signal hydraulic system requirements to a c 6 OF implement performance.

Closed-center implement valves signal hydraulic system requirements to a control valve located on the pumpa Clamps and Bushings. Metal clamps with rubber bushings are used at hose attachment points to eliminate metal-tometal contact and increase wear life. Cat XT-3 ES ToughGuardw Hoses. Improved bend radius and abrasion resistance provide reliable long life in the toughest conditions. Made of four overlapping, insulated Wire spiral wraps bonded together for durability, Cat XT-3 ES (Enhanced Spiral) ToughGuard hoses exceed SAE certification standards. The hose routing protects them from work damage, and hose failure is substantially reduced. Cat XT-3 ES ToughGuard hoses combined with Cat couplings and 0-ring face seal fittings provide a leak-free system.

Al backhoe hydraulic circuits utilize the new ToughGuard hose with extended wear characteristics. Power Train The Cato C4. 4 engine is built for performance, power, reliability and fuel efficiency. Auto-Shift Transmission. The standard automatic transmission matches gears with grade and load conditions. Top gear is selected with the twist grip control on the steering column. At the touch of a switch, manual mode gives the operator control over gear selection, as a power shift transmission. Transmission Kick Down Switch/ Neutralizer. Located on the loader control, the kick- down switch allows the operator to downshift through the gears. When this switch is depressed for more than one se perator to downshift through the gears.

When this switch is depressed for more than one second, it serves as the transmission neutralizer to maintain engine and hydraulic Speed when truck loading. Standard Four Wheel Drive (4WD). Heavy- duty front drive axle can be engaged at any time by activating the switch on the front console. The switch can be activated while the machine is stopped or moving, with or without load. 4WD features outboard planetary gear final drives and improves mobility and loader performance in poor traction conditions. Brake Mode Selector. The brake mode selector switch has three ositions: two wheel drive, 0010 wheel drive with all wheel braking and all wheel drive.
