Komatsu PC2000-8 EXCAVATORS FINAL DRIVE ASSEMBLY 21T-27-00300 FINAL DRIVE MOTOR HIGH QUALITY TRAVEL MOTOR CONSTRUCTION MACHINERY

The Final Drive / Travel Motor (Part No. 21T-27-00300) for the Komatsu PC2000-8 hydraulic mining shovel is an ultra-heavy-duty travel propulsion unit engineered for large-scale open-pit mining and heavy earthmoving 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, coal, 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: Massive displacement axial piston motor delivers extraordinary starting torque and smooth power transmission for efficient maneuvering on steep mine ramps and uneven surfaces.
• Heavy-Duty Multi-Stage Planetary Reduction: Case-hardened alloy steel planetary gears with precision-ground tooth profiles ensure uniform load distribution and maximum service life.
• Super-Class Structural Integrity: Massive ductile iron housing with reinforced ribbing and stress-relieved construction resists 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.
• Extended Service Life Under Extreme Loads: Oversized bearings, extra-hardened gear sets, and optimized lubrication pathways withstand 24/7 mining production demands.

• Hydraulic System Care: Routinely inspect case drain lines for restrictions and maintain strict hydraulic fluid cleanliness standards with high-efficiency filtration.
• Gear Oil Management: Change oil every 250-500 operating hours under normal conditions, and every 250 hours in severe applications. Perform regular oil sampling and spectrometric analysis.
• Mounting Bolt Protocol: Always fit new high-strength bolts with thread locking compound torqued to factory specifications to prevent loosening from extreme vibration.
• Pre-Operation Priming Procedure: Fill motor housing with clean hydraulic oil and run machine at low idle to purge air pockets and ensure complete lubrication before heavy loads.
