7 Standard Features Transmission Programmable Top Gear Selection Allows the operator to manually set the top gear (3rd -8th) available to match the conditions or to match the hauling speed of the fleet to specific job-site needs. Retarder Power Train Transmission Integrated electronics slows the machine to monitor the power train which reduces stress as well as provides a better ride to the operator. Transmission Electronically controlled Caterpillar planetary powershift transmission with eight forward and one reverse speed. Tractor gear 1 & 2 operate in converter drive for increased torque capability during cut and fill operations. Gears 3-8 operate in direct drive for drive train efficiency during the haul. All scraper gears operate in converter drive for increased torque capability during the cut and fill. Synchronized Scraper Transmission The scraper transmission is electronically controlled by the tractor transmission, synchronizing the scraper transmission gear selection with that of the tractor transmission. The scraper transmission cannot be shifted manually. A neutral/run switch, located in the cab, allows the operator to disengage the scraper transmission. Planetary Design Provides larger contact area between gears than countershaft transmission for greater load-carrying capacity. Transmission Hold Allows the operator to maintain converter for increased drive for the increased rimpull, or hold the current gear for enhanced control. The retarder should be used on downgrades to reduce wear on the service brakes and enhance machine control. The retarder acts as an internal brake on the driveline that minimizes the need to apply service brakes. The operator typically engages the retarder 3 to 4 seconds before the machine begins a downhill grade. Differential Control Electronic differential lock helps prevent the drive wheels from spinning in poor underfoot conditions located in the cab. Neutral Coast Inhibitor Neutral coast inhibitor prevents the transmission from shifting into neutral if the operator selects neutral while moving. Final Drives Outboard-mounted planetary design final drives reduce torque loads on other power train components. Large-capacity, double-row roller bearings and Caterpillar Duo-Cone seals deliver exceptional reliability in the toughest applications. Independent Systems Expanding shoe-type breaks are a cam-operated design that is air-applied and spring released. The breaking systems uses independent front and rear circuits with secondary brakes automatically applied if the service air pressure drops to 380 kpa (55psi). Parking Breaks The push-button operated parking break features a spring-applied, air released mechanism that operates the service brakes. 5

8 Standard Features Operator s Station Simple and easy to operate, the joystick enhances the productivity of operators of all skill levels. Requires less force to control the critical scraper functions and requires less lever travel.

Implement value mounting on top of gooseneck to reduce damage. 50% increase in material thickness at bowl lift cylinder attaching points. Teardrop Shape increases gooseneck durability. 7

10 Standard Features Cushion Hitch (Electronically Controlled) Load Cylinder Hitch Castings Scraper Gooseneck Nitrogen Accumulators Orifice Oil From Tractor Hydraulic System Leveling Valve Free Floating Pistons Cushion Hitch The electronically actuated cushion hitch incorporates a parallelogram-type linkage for exceptional strength with nitrogen accumulators to deliver a smooth ride for enhanced operator comfort. Controlled oil flow dampens rebound oscillation Leveling valve automatically centers piston in cylinder for all loads. Steel castings are used extensively to eliminate many welding joints and increased strength. Double kingbolt design withstands high external forces and simplifies installation and removal. Nitrogen Accumulators Vertically mounted hydraulic cylinder transfers road shock to nitrogen accumulators. Nitrogen accumulators absorb and dampen road shock thus preventing these loads from being transmitted to the operator. Lockout Switch An operator-selectable lockout switch, located on the joystick, locks all cushion hitch for improved control of the cutting edge during loading and dumping. 8

11 Standard Features-Structures Elevator Design Single drive motor provides improved life over original dual motor design torque oscillation between motors is eliminated. A high torque hydraulic drive motor turns the elevator at a constant speed under heavy loads. This lets the operator select the best loading depth without continual adjustment. Leaves the cut smooth for easier, more efficient loading on the next pass Single speed reducer & drive motor. Two piece steel casting mount for ease of component replacement. Elevator arms moved to inside of bowl to prevent trunnion cracking. Robust lever-type elevator adjustment mechanism replaces telescopic version. Improved elevator frame design utilizes upper level steel corner castings and simplified lower frame. 9

12 Standard Features-Structures Bowl Design Bowl cutting edge supports a variety of Caterpillar Ground-Engaging Tools (GET). Cellular construction adds strength and dent resistance to bowl sides and floor. Rugged J-link design is used to operate the rotating floor. The rotating floor scrapes the side of the bowl clean without the use of rollers and tracks which can be deformed or bound by falling material. Swinging Elevator Mounting System protects flights and cutting edge against sudden shock.
