Caterpillar 785C Differential

Description

OEM-Quality Caterpillar 785C Differential Assembly

Maintain optimal power transmission and backend axle balance across your mining haul fleet with a heavy-duty Caterpillar 785C Differential Assembly. Engineered specifically for Caterpillar’s 150-ton class (136-tonne nominal payload) off-highway mining trucks, this differential unit transfers power from the transmission output shaft to the rear drive axles while balancing outer and inner wheel speeds during cornering and uneven haul road navigation.

Featuring Caterpillar’s proven spiral bevel crown wheel and pinion architecture, this assembly absorbs severe torsional shock loads while delivering smooth torque multiplication to the 785C’s outer planetary final drives.

Key Features & Benefits

• Precision Spiral Bevel Gearing: High-strength alloy steel ring and pinion gear set built to handle high continuous torque with low vibration and minimal gear face fatigue.

• Full-Floating Axle Housing Interface: Isolates the differential carrier from vehicle weight and structural frame flexing, ensuring axle shafts carry rotational torque only.

• High-Efficiency Thermal & Oil Circulation: Designed with internal oil galleries to ensure constant lubrication across carrier bearings, pinion bearings, and spider gears under heavy load cycles.

• Traction Control System (TCS) Compatible: Fully integrated with Caterpillar’s electronic braking system to prevent wheel slippage on slippery bench cuts or wet haul roads.

• Direct OEM Frame & Housing Bolt-In: Engineered to exact Caterpillar 785C factory tolerances for seamless installation into standard rear axle housings and drive flange yokes.
