Komatsu PC210-10 Final Drive Assembly 20Y-27-00540 20Y-27-00541 | High-Efficiency Axial Piston Travel Motor | Precision Planetary Gearbox | Heavy-Duty Hydraulic Propulsion Unit

The PC210-10 platform is utilized across diverse global markets, and our travel devices are optimized for region-specific operating conditions:

• North America & Europe: Configured with enhanced bearing preload and upgraded seal packs to withstand the high-cycle demands of utility contracting, road maintenance, and rental fleet operations in urban infrastructure projects
• Southeast Asia & Oceania: Equipped with heavy-duty floating seals and corrosion-resistant output shaft surfaces to prevent contamination from abrasive laterite soils, monsoon mud, and coastal humidity in tropical construction and plantation applications
• Japan & East Asia: Tuned to match the PC210-10's advanced CLSS hydraulic control system, providing the precise travel modulation and smooth start/stop characteristics required for confined urban worksites and precision grading operations

• Compact High-Torque Design: Optimized planetary gear ratio delivers maximum drawbar pull while maintaining a compact housing profile that fits within the PC210-10's narrow track frame without clearance issues
• Hydraulic System Integration: Full compatibility with Komatsu's Closed-center Load Sensing System (CLSS) and electronically controlled travel pedals for precise speed control and smooth directional transitions
• Durable Construction: Induction-hardened sun gears, carburized planetary pinions, and high-strength ductile iron housing resist fatigue and structural stress during repetitive loading in trenching and foundation work
• Direct OEM Fitment: All mounting bolt patterns, hydraulic port locations (SAE O-ring boss), and pilot line orientations match original Komatsu specifications for straightforward replacement without undercarriage modifications

• Hydraulic System Care: Routinely inspect case drain line backpressure; readings exceeding 5 kg/cm² indicate internal motor wear requiring attention. Replace hydraulic return filters every 250 hours and pilot filters every 500 hours to maintain clean oil supply to travel motor circuits
• Gear Oil Management: Drain and replenish planetary gearbox oil every 500 operating hours under normal conditions, or every 250 hours in dusty or high-humidity environments. Use SAE 80W-90 API GL-5 gear oil; verify floating seal compatibility before switching to synthetic alternatives
• Mounting Bolt Protocol: Always install new OEM-specification mounting bolts with medium-strength thread locker. Tighten in a three-stage cross-pattern sequence at 50%, 75%, and 100% of specified torque to ensure even clamping force and prevent housing distortion
• Pre-Start Priming Procedure: Before initial engine startup following travel device replacement, completely fill the motor housing with clean ISO VG 46 hydraulic oil through the uppermost port. Manually rotate the output shaft in both directions to displace trapped air, then verify oil level before operation to prevent dry-start damage to piston shoes and valve plate surfaces
