Product Description
KOMATSU PC210-10 PC210-10MO EXCAVATORS FINAL DRIVE ASSEMBLY 708-8F-31320 FINAL DRIVE MOTOR HIGH QUALITY TRAVEL MOTOR CONSTRUCTION MACHINERY
The Final Drive Motor (Part No. 708-8F-31320) for Komatsu PC210-10 and PC210-10MO excavators is a heavy-duty travel propulsion unit engineered for medium-to-large scale construction, mining, and earthmoving operations in the 21-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 machine models.

Regional Application & Market Suitability
North America & Europe
Engineered for heavy civil construction, road building, and infrastructure projects, with reinforced housing and enhanced sealing to withstand extreme temperature variations, abrasive materials, and continuous high-cycle operation.
Southeast Asia & Oceania
Equipped with heavy-duty floating seals that resist ingress of highly abrasive laterite soils, clay, and tropical mud common in mining, plantation, and large-scale earthworks projects.
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 environments.
Key Features & Performance Advantages
- High-Torque Axial Piston Motor: The swashplate-type motor design delivers strong starting torque and smooth speed control, enabling efficient tracking on steep slopes, soft ground, and uneven terrain.
- Multi-Stage Planetary Reduction: The gearbox employs heat-treated alloy steel planetary gears manufactured to tight tolerances, ensuring even load distribution across multiple contact points and extended service life between major overhauls.
- Cross-Model Compatibility: Engineered to fit both PC210-10 and PC210-10MO excavators with identical mounting dimensions, pilot bores, spline connections, and hydraulic port locations, providing exceptional flexibility for mixed fleet maintenance and inventory management.
- Precision OEM Replacement Fit: All mounting bolt patterns, pilot diameters, spline connections, and hydraulic port locations match original Komatsu specifications, enabling seamless installation with minimal machine downtime.
- Industrial-Grade Structural Integrity: The cast iron housing features reinforced ribbing and stress-relieved construction to resist structural fatigue under continuous shock loading, while dual-cone floating seals protect internal components from contamination.
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 motor rotary group failure or seal damage. Maintain clean hydraulic fluid and replace return filters according to the machine's prescribed service schedule.
- Gear Oil Management: Fill the planetary housing with the recommended extreme-pressure gear oil of the correct viscosity grade. Change the oil every 250-500 operating hours under normal conditions, and every 250 hours in severe applications such as quarry work, demolition, or continuous heavy digging. Examine drained oil for metallic particles as an early diagnostic indicator of gear or bearing wear.
- Mounting Bolt Protocol: When reinstalling the final drive motor, always fit new high-strength bolts. Apply a suitable thread locking compound to the bolt threads prior to torquing to factory specifications, preventing loosening caused by continuous vibration and shock loads during travel and digging operations.
- 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 operational loads.
