Product Description
KOMATSU PC490-10 PC490LC-10 EXCAVATORS FINAL DRIVE ASSEMBLY 208-27-00450 FINAL DRIVE MOTOR HIGH QUALITY TRAVEL MOTOR CONSTRUCTION MACHINERY
The Final Drive Motor (Part No. 208-27-00450) for Komatsu PC490-10 and PC490LC-10 excavators is a heavy-duty travel propulsion unit engineered for large-scale mining, quarry operations, and major earthmoving projects in the 49-ton machine class. This assembly integrates a high-displacement axial piston hydraulic motor with a rugged multi-stage planetary reduction gearbox, delivering exceptional tractive effort and reliable travel performance under sustained heavy-load conditions. It is designed as a direct OEM replacement, ensuring precise fitment and factory-specified hydraulic performance for both standard and long-carriage configurations.

Regional Application & Market Suitability
- North America & South America: Engineered for large-scale open-pit mining, quarry operations, and heavy infrastructure projects, with reinforced housing and enhanced sealing to withstand extreme temperature variations, abrasive materials, 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.
- Middle East & Africa: 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.
Key Features & Performance Advantages
- High-Displacement Torque Delivery: The axial piston motor design provides substantial starting torque and smooth power transmission, enabling efficient tracking on steep mine ramps, soft overburden, and uneven bench floors.
- Multi-Stage Planetary Reduction: The gearbox employs case-hardened alloy steel planetary gears with precision-ground tooth profiles, ensuring uniform load distribution across multiple stages and maximizing service life between major rebuilds.
- Precision OEM Replacement Fit: All mounting bolt patterns, pilot diameters, spline connections, and hydraulic port locations match original Komatsu specifications for the PC490-10 and PC490LC-10 models, enabling seamless installation with minimal machine downtime.
- Modern Design Compatibility: Engineered specifically for the PC490-10 series' updated hydraulic system and undercarriage configuration, ensuring optimal travel performance, fuel efficiency, and reliability in demanding applications.
- Mining-Grade Structural Integrity: The ductile iron housing features massive reinforced ribbing and stress-relieved construction to resist structural fatigue under continuous shock loading. Dual-cone floating seals with heavy-duty dust wipers provide robust protection against contamination in the harshest environments.
Expert Maintenance Guidance
- Hydraulic System Care: Routinely inspect case drain lines for restrictions, kinks, or blockages. A restricted drain line can generate excessive back pressure, leading to catastrophic motor rotary group failure. Maintain strict hydraulic fluid cleanliness standards and replace return filters at intervals prescribed for heavy mining equipment.
- Gear Oil Management: Fill the planetary housing with the recommended extreme-pressure gear oil of the correct viscosity grade for heavy-duty applications. Change the oil every 250-500 operating hours under normal conditions, and every 250 hours in severe applications such as continuous mining, quarry production, or heavy ripping. Perform regular oil sampling and analysis to detect metallic particles as an early indicator of gear or bearing degradation.
- Mounting Bolt Protocol: When reinstalling the final drive motor, always fit new high-strength bolts meeting the specified grade. Apply a suitable thread locking compound to the bolt threads prior to torquing to factory specifications, preventing loosening caused by extreme vibration and shock loads during tramming and digging cycles.
- Pre-Operation Priming Procedure: Before initial startup or after final drive replacement, fill the motor housing with clean hydraulic oil to purge trapped air pockets. Run the machine at low idle for several minutes, cycling the tracks forward and reverse, to ensure complete lubrication of all planetary components before engaging heavy production loads.
