KOMATSU PC360-10 EXCAVATORS FINAL DRIVE ASSEMBLY 207-27-00480 FINAL DRIVE MOTOR HIGH QUALITY TRAVEL MOTOR CONSTRUCTION MACHINERY

The Final Drive Unit (Part No. 207-27-00480) for the Komatsu PC360-10 excavator is a heavy-duty travel propulsion assembly engineered for demanding earthmoving, quarry operations, and infrastructure development in the 36-ton machine class. This unit 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.

• North America & Europe: Engineered for heavy civil construction, road building, quarry operations, and demolition projects, with reinforced housing and enhanced sealing to withstand high-frequency use, cold-weather startups, and abrasive winter road treatments.
• Southeast Asia & Oceania: Equipped with heavy-duty floating seals that resist ingress of 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 cycling, and airborne dust in arid desert and semi-arid environments.

• 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.
• Precision OEM Replacement Fit: All mounting bolt patterns, pilot diameters, spline connections, and hydraulic port locations match original Komatsu specifications for the PC360-10 model, enabling seamless installation with minimal machine downtime.
• Modern Design Compatibility: Engineered specifically for the PC360-10's updated hydraulic system and undercarriage configuration, ensuring optimal travel performance, fuel efficiency, and reliability in demanding applications.
• 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.

• 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.
• Mounting Bolt Protocol: When reinstalling the final drive unit, 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.
