Power Train ­ Engine The Cat C27 engine with ACERT Technology uses advanced engine technology to reduce emissions without after-treatment. The turbocharged, aftercooled 12-cylinder engine has higher horsepower and faster response for superior performance in demanding applications. [. . . ] Automatic brake modulation offers a smoother ride and better control in slippery conditions, allowing the operator to concentrate on driving. ARC increases operating ease, resulting in greater operator confidence with less fatigue. Automatically activates ARC when engine speed exceeds factory preset levels, regardless of operator inputs, to avoid potentially damaging engine overspeeds. Traction Control System (TCS) (optional). Electronically monitors and controls rear wheel slippage for greater traction and enhanced truck performance in poor underfoot conditions. If slippage exceeds a set limit, the oil-cooled disc brakes engage to slow the spinning wheel. Torque is then automatically transferred to the wheel with better traction. Normal differential action provides superior maneuvering and control in slippery conditions. Optional Compression Brake is integrated with Automatic Retarder Control (ARC) to provide up to 35 percent higher downhill travel speed and reduce wear on brake components. 1500 1000 500 0 10 20 30 40 50 Time (Seconds) 60 70 With Automatic Retarder Control (average speed, 1950 rpm) With Manual Retarder Control (average speed, 1730 rpm) · Faster Speeds. ARC allows the operator to maintain optimum engine speeds for up to 15 percent faster downhill hauls and greater productivity. 11 Serviceability Less time spent on maintenance means more time on the haul roads. On-Board Diagnostic Systems. Messenger continuously checks all critical machine functions and components, and helps locate faults quickly for faster repair. Electronic control system enables quick diagnosis of engine conditions and effective maintenance and repairs using the Electronic Technician (Cat ET) service tool. This advanced lubrication system is available as a factory installed option on the 773F. Clustered grease fittings save time as all lubrication points are mounted in three main locations. New "rope-type" oil dipstick improves serviceability by allowing easy daily checks. This cooling system's new modular design permits removal of a single core without removing the entire radiator, reducing downtime and repair costs. The less complex design offers improved reliability and higher efficiency over the two-pass flow core. NGMR also offers wider fin spacing for greater resistance to plugging and more convenient cleaning. Oil change labor time is reduced by as much as 50 percent with this standard on-board engine oil evacuation and pre-lube system. It speeds the process of evacuating the engine sump and allows for the purging of oil filters prior to removal, minimizing oil spills. QuickEvac system also enhances contamination control by ensuring complete filtration of new oil on engine refill. The C27 engine with ACERT Technology offers 500-hour service intervals under normal conditions. For the 773F, commonly used engine service points have been placed on the right side of the engine. [. . . ] The ladder on the left side of the machine permits secondary egress. A stairway lamp illuminates the cab access stairs and can be activated at ground level during entry and shut off with a switch in the cab. · · · · · · · · · Slip resistant surfaces 75 mm (3 in) wide orange three-point operator restraint Heated, wide-angle mirrors Body raised indicator Guard rails Reverse neutralizer when dumping Low interior sound level Service platform level transmission, hoist and steering disable switch Service platform level starter disable switch 17 Engine Engine Model Rated Engine Speed Gross Power ­ SAE J1995 Net Power ­ SAE J1349 Net Power ­ ISO 9249 Net Power ­ 80/1269/EEC Number of Cylinders Peak Torque Bore Stroke Displacement Cat ® C27 ACERT ® 1, 800 rpm 552 kW 740 hp 524 kW 703 hp 524 kW 703 hp 524 kW 703 hp 12 3399 N·m 2, 507 lb ft 137 mm 5. 4 in 152 mm 6 in 27 L 1, 649 in3 Transmission Forward 1 Forward 2 Forward 3 Forward 4 Forward 5 Forward 6 Forward 7 Reverse 10. 8 km/h 15 km/h 20. 3 km/h 27. 3 km/h 37 km/h 49. 9 km/h 67. 5 km/h 14. 2 km/h 6. 7 mph 9. 3 mph 12. 6 mph 17 mph 23 mph 31 mph 41. 9 mph 8. 8 mph · Maximum travel speeds with standard 24. 00R35 (E4) tires. · Power ratings apply at 1, 800 rpm when tested under the specified condition for the specified standard. · Ratings based on SAE J1995 standard air conditions of 25° C (77° F) and 100 kPa (29. 61 Hg) barometer.
