KOMATSU PC2000-8 EXCAVATORS FINAL DRIVE ASSEMBLY 706-7L-01110 FINAL DRIVE MOTOR HIGH QUALITY TRAVEL MOTOR CONSTRUCTION MACHINERY

The Final Drive Unit (Part No. 706-7L-01110) for the Komatsu PC2000-8 hydraulic mining shovel is an ultra-heavy-duty travel propulsion unit engineered for large-scale open-pit mining operations in the 200-ton machine class. This assembly integrates a massive high-displacement axial piston hydraulic motor with an extremely rugged multi-stage planetary reduction gearbox, delivering extraordinary tractive effort and reliable travel performance under continuous extreme-load conditions.

• North America & South America: Engineered for large-scale open-pit copper, gold, and oil sands mining operations, with reinforced housing and enhanced sealing to withstand extreme temperature variations, abrasive slurry, and continuous high-cycle operation.
• Australia & Oceania: Equipped with heavy-duty floating seals that resist ingress of highly abrasive quartz-rich soils, red dust, and laterite materials common in iron ore and coal mining environments.
• Africa & Middle East: High-temperature seals and corrosion-resistant materials protect against sand erosion, thermal stress, and airborne particulate contamination in arid desert and semi-arid mining regions.

• Ultra-High Torque Capacity: The massive displacement axial piston motor delivers extraordinary starting torque and smooth power transmission, enabling efficient maneuvering on steep mine ramps, soft overburden, and uneven bench floors.
• Heavy-Duty Multi-Stage Planetary Reduction: The gearbox employs case-hardened alloy steel planetary gears with precision-ground tooth profiles, ensuring uniform load distribution and maximizing service life between major rebuilds.
• Super-Class Structural Integrity: The ductile iron housing features massive reinforced ribbing and stress-relieved construction to resist structural fatigue under continuous shock loading.
• Precision OEM Replacement Fit: All mounting bolt patterns, pilot diameters, spline connections, and hydraulic port locations match original Komatsu specifications for seamless installation with minimal machine downtime.

• Hydraulic System Care: Routinely inspect case drain lines for restrictions, kinks, or blockages. Maintain strict hydraulic fluid cleanliness standards and replace return filters at prescribed intervals.
• Gear Oil Management: Fill the planetary housing with recommended extreme-pressure gear oil. Change oil every 250-500 operating hours under normal conditions, and every 250 hours in severe applications.
• Mounting Bolt Protocol: Always fit new high-strength bolts with thread locking compound and torque to factory specifications to prevent loosening from extreme vibration and shock loads.
• Pre-Operation Priming Procedure: Before initial startup or after final drive replacement, fill the motor housing with clean hydraulic oil and run the machine at low idle to ensure complete lubrication.
