Torque Converter The lock-up torque converter combines the maximum rimpull and cushioned shifting of torque converter drive with the efficiency and performance of direct drive. Power Shift Transmission The six-speed, planetary power shift transmission utilizes pressure valve to regulate clutch pressure rise and fall to ease clutch engagement. This reduces shock loads on power train components. Final Drives Final drives and differential torque multiplication of Transmission and Torque Converter Sump Transmission and torque converter share a common sump.
771s combined sump offers an easily accessible fill tube and site gauges. Axles Full floating axles are shot peened to relieve internal stresses and increase durability. Rolled splines also provide increased service life.

Rear Wheels and Rims Cat rear wheels and Cat center-mount rims are mounted using studs and nuts to minimize maintenance and maximize durability. Transmission Chassis Controller TCC Transmission chassis Controller TCC uses electronically transferred engine rpm data to execute shifts at preset points for optimum performance and efficiency.
Power Train Integration Caterpillar’s power train integration provides increased component life and operator comfort. Engine The eight-cylinder, turbocharged and aftercooled HEUI engine is built for power, reliability and economy with reduced sound levels and low emission. Diesel Engine The Cat E Diesel Engine is a four-stroke design that uses long power strokes for more complete fuel combustion and optimum efficiency. Torque Rise The torque rise provides high lugging force during acceleration on grade or in high rimpull conditions.
This system electronically monitors operator and machine inputs to optimize engine performance. The electronic engine and transmission controls provide exhaustive diagnostic capability for service technicians.
Oil-cooled Rear Brakes Reliable braking lets the operator concentrate on the haul road. Disc Brakes Caterpillar forced oil-cooled, multiple disc brakes are continuously cooled for exceptional, fade-resistant braking and retarding. Oil-cooled Disc Brakes Oil-cooled disc brakes are designed and built for reliable, adjustment-free operation providing superior performance and service life in comparison to shoe-type and dry-disc system.
Oil Film An oil film prevents direct contact between the discs. Absorbing the braking forces by shearing oil and carrying heat away, this design brake life. Pistons A Caterpillar patented, two-piston design combines the service, secondary, parking brake, and retarding functions.
Cat Retarding System When retarding, the engine runs against compression on downhill hauls, resulting in minimal fuel burn. Structures The backbone of the Cat truck. Box-Section Design The D frame uses a box-section design, incorporating 17 castings in high-stress areas, with deep-penetrating and continuous wrap-around welding. Castings Castings have large radii with internal reinforcing ribs to dissipate stress. Castings move welds to lower stress areas and provide two to three times the strength of equivalent-sized fabricated structures.
Suspension System The suspension system is designed to dissipate haul road and loading impacts for extended frame life. Flat Floor Body Caterpillar offers excellent wear characteristics in a flat floor design. Quarry Body The flat floor quarry body offers excellent load retention on grades up to 12 percent and on smoother haul road conditions. Maximum payload is reached in three to five passes from a matched Cat loader.
Construction Body floor construction uses a 12 degree single slope, offering excellent wear characteristics and uniform dumping into hoppers, crushers, and feeders.

Sidewall and Floor Junctions Sidewall and floor junctions are joined by five-sided beams to resist impact loading and sustained hauling stresses. Box-section Beams Box-section beams offer increased durability in the floor, sidewalls, top rail, corner and cab canopy areas.
Standard Body Standard body comes exhaust heated with options including a full-time muffler or exhaust diverter.
Operator Station Control ease and comfort maximizes productivity. Dash Panel The wraparound czt panel is provided in an easy line-of-sight arrangement, using LED backlit rocker switches.
The seat is fully adjustable and includes an adjustable right-hand armrest. Visibility Exceptional all-around visibility reduces fatigue and improves productivity. Front Brake Cut-out Switch Front brake cut-out switch increases front brake component life. Storage Compartment Large storage compartment is located under the trainer’s seat. The system features three separate displays.
Foot Pedals Ergonomically designed foot 771s for increased operator comfort. Secondary brake moved to floor. Hoist Lever Electrohydraulic hoist lever is finger tip actuated and provides low-impact body-down snubbing.
Automatic 771c Control Optional Electronically controls braking on grades for improved engine and brake component life. Operating Efficiency ARC results in increased operating efficiency with faster downhill speeds. By maintaining consistently higher engine speeds, average 771d speed will be higher than a manually controlled truck.
Controllability ARC results in excellent controllability and reduced operator effort. Automatic brake modulation provides a smoother ride over manual modulation, allowing the operator to focus more on truck operation down the haul road. Component Life ARC results in improved component life, optimized system cooling capability, and reduced torque fluctuations result from the precision of ARC.
Operator Awareness Operator awareness through electronic integration and the CEMS, alerting the operator to overspeed conditions and critical machine functions. Traction Control System Optional Electronically controls cst slippage for 77d1 performance. Differential Action TCS utilizes normal differential action to provide superior maneuvering in poor underfoot conditions.
Torque TCS divides torque equally to reduce stress created on final drives and axles when torque is transferred to one side.
Back-up Design TCS maintains the back-up design. Should the sensors fail, normal differential action is still available to maintain control and steering. Body Options Body options include a full line cxt standard and custom designs based on specific customer preference, material density, loading tools and site conditions.
Tire Options A full line of tire options, representing various manufacturers, is offered by Caterpillar to maximize performance and life for specific applications. Caterpillar System Approach The Caterpillar system approach means increased caat through “common design”. Maintenance Platform The maintenance platform provides access to air tank, brake master cylinder, and make-up tank, engine oil level, air filters, steering hydraulic tank, and battery compartment.
Battery Disconnect Switch A ground-level battery disconnect switch facilitates safe, convenient servicing and maintenance. Diagnostics with ET Off-board diagnostics with ET allows service technicians access to stored diagnostics data reducing down time and lowering operating costs.
Air Filters Radial seal air filters are easy to change, reducing air filter maintenance times. Oil Filters Vertical, spin-on oil filters provide for simplified servicing.
Quick Coupler Quick coupler pressure taps, located in all hydraulic dat, provide clear, quick pressure checks. SOS oil analysis points make oil sampling quick, clean, and easy. Electrical Connectors Sealed electrical connectors lockout dust and moisture.
