Caterpillar 777G Final Drive

Description

OEM-Quality Caterpillar 777G Final Drive Assembly

Ensure uninterrupted productivity and high-torque delivery across your quarry or mining haul fleet with a heavy-duty Caterpillar 777G Final Drive Assembly. Designed specifically for Caterpillar’s 100-ton class (91.4-tonne nominal payload) off-highway haul trucks, this final drive system multiplies engine torque right at the drive wheels while isolating upstream components from heavy shock loads.

Featuring Caterpillar’s field-proven double-reduction planetary gear system, this assembly delivers extreme rim pull capacity for steep incline haulage while protecting the differential and transmission driveshaft from torsional fatigue.

Key Features & Benefits

• Double-Reduction Planetary Design: Converts high-speed input into heavy-duty low-speed wheel rim power, minimizing gear face wear during high-load hauls.

• Full-Floating Axle System: Axle shafts transmit torsional loads exclusively—not machine weight—extending the operational lifespan of the axles, planet gears, and face seals.

• Superior Contamination & Thermal Control: Precision-machined oil flow channels ensure continuous lubrication and heat dissipation around planet gears during prolonged downhill retarding.

• Heavy-Duty Metal-to-Metal Duo-Cone Seals: Maintains absolute seal integrity to keep out fine quarry dust, mud, and water slurry under severe environmental conditions.

• Direct Wheel Hub & Brake Integration: Engineered for seamless bolt-on fitment with standard Caterpillar 777G rear wheel hubs, axle housings, and oil-cooled multi-disc brake assemblies.
