Power Train – Engine The Cat® C32 engine with ACERT™ Technology is built for power, reliability and efficiency for superior performance in the toughest applications. Single-Piece Piston Design. New single-piece forged steel pistons with integrated forged steel skirt are more robust to withstand high engine heat and pressure, and enable enhanced combustion efficiency, improved fuel efficiency and lower emissions. Corrosion-resistant, stainless steel top ring reduces ring, groove and liner wear for greater reliability and longer life. MEUI Fuel System. Fuel delivery, provided by the MEUI...

Power Train – Transmission Cat power train delivers more power to the ground for greater productivity and lower operating costs. Mechanical Power Train. The Cat mechanical drive power train and power shift transmission provides unmatched operating efficiency and control on steep grades, in poor underfoot conditions, and on haul roads with high rolling resistance. Transmission. Pairing the Caterpillar seven-speed planetary power shift transmission with the C32 diesel engine with ACERT Technology delivers constant power over a wide range of operating speeds. • Long Life. A dedicated...

Structures Rugged Cat structures are the backbone of the 777F off-highway truck’s durability. Suspension System. Designed to dissipate haul-road and loading impacts for longer frame life and a more comfortable ride. • Cylinders. Four independent selfcontained, oil pneumatic, variablerebound suspension cylinders are designed to absorb shocks in the most severe applications. • Durable Design. Rugged cylinders use a large diameter bore and low pressure nitrogen/oil design for long life with minimal maintenance. – Front. Front cylinders with preset caster and camber are mounted to the frame and...

Operator’s Station Ergonomically designed for operator comfort, superior control and high productivity. Ergonomic Layout. The 777F operator station is ergonomically designed for total machine control in a comfortable, productive and safe environment. All controls, levers, switches and gauges are positioned to maximize productivity and minimize operator fatigue. New ISO Designed Cab Mounts. Integral, sound-suppressed cab is resiliently mounted to the frame to isolate the operator from sound and vibration for a quiet, secure and comfortable ride. Viewing Area. Designed for excellent...

Body-up Reverse Neutralizer. Automatically shifts the transmission to neutral if the hoist lever is activated while the transmission is shifted in reverse. Overspeed Protection. The transmission control electronically senses engine conditions and automatically up-shifts one gear to prevent overspeeding. If overspeeding occurs in the top gear, the lock-up clutch is disengaged, and the brakes are applied. Programmable Top Gear. Transmission top gear maximum can be set using Cat Messenger, VIMS Advisor or the Cat ET service tool to help the operator maintain speed limits. Anti-Hunt Function....

Brake System Reliable braking with superior control gives the operator the confidence to focus on productivity. Long Life. An oil film prevents direct contact between the discs. This design absorbs the braking forces by shearing the oil molecules and carrying heat away to extend brake life. Pistons. The Caterpillar two-piece piston design combines the service, secondary, parking brake and retarding functions in the same system. The primary piston hydraulically actuates both service and retarding functions. The secondary piston is spring-applied and held in the disengaged position by...
