Caterpillar 777G Torque Converter

Description

OEM-Quality Caterpillar 777G Torque Converter Assembly

Maximize rimpull torque during heavy loading and optimize fuel efficiency on haul roads with a heavy-duty Caterpillar 777G Torque Converter Assembly. Built specifically for Caterpillar’s 100-ton class (91.4-tonne nominal payload) off-highway trucks, this heavy torque converter unit bridges the Cat C32 ACERT engine and the 7-speed planetary power shift transmission.

Equipped with Caterpillar’s field-proven Lock-Up Clutch (LUC), this assembly provides high fluid-coupling torque multiplication during launch and directional shifts, then engages a direct mechanical drive at higher speeds to eliminate fluid slip and lower operating costs.

Key Features & Benefits

• Integrated Lock-Up Clutch (LUC): Seamlessly shifts from hydrodynamic fluid drive to direct mechanical drive, maximizing power transfer to the wheels and increasing fuel efficiency.

• Matched to Cat C32 ACERT Engine: Specifically tuned to match the horsepower and torque curves of the Cat 1,025 hp (765 kW) diesel powerplant.

• Heavy-Duty Impeller & Turbine Construction: Forged, heat-treated internal blading designed to handle severe hydraulic pressure spikes and continuous high-load cycles.

• Advanced Oil Flow Cooling: Designed for continuous high-rate transmission oil circulation to dissipate heat quickly during prolonged torque multiplication under heavy incline starts.

• Direct OEM Bolt-On Fit: Engineered to exact Caterpillar 777G housing standards for direct mounting to the engine flywheel housing and transmission input drive shaft.
