The Final Drive (Travel Motor) Part No. 22J-60-25401 for the Komatsu PC18MR mini excavator is a compact, high-torque propulsion unit engineered for tight-radius excavation and utility applications in the 1.8-ton machine class. This assembly integrates a high-efficiency axial piston hydraulic motor with a precision multi-stage planetary reduction gearbox, delivering reliable tractive effort and smooth travel performance in confined urban and residential work environments.

• North America & Europe: Designed for municipal utility work, residential landscaping, and indoor renovation projects with enhanced cold-weather sealing and low-noise characteristics.
• Southeast Asia & Oceania: Equipped with heavy-duty floating seals that resist abrasive mud, clay, and tropical soils in high-humidity environments.
• Middle East & Africa: Reinforced housing and high-temperature seals protect against sand abrasion and thermal stress in arid desert conditions.

• Compact Urban-Optimized Design: Dimensionally engineered to fit within the narrow undercarriage of the PC18MR without compromising performance.
• Precision Multi-Stage Reduction: Planetary gear set with heat-treated alloy steel components for extended service intervals.
• Precision OEM Replacement Fit: All mounting patterns and connections match original Komatsu specifications for seamless installation.
• Robust Contamination Defense: Dual-cone floating seals with heavy-duty dust wipers for protection in wet, dusty environments.

• Hydraulic System Care: Routinely inspect case drain lines and maintain clean hydraulic fluid with regular filter replacement.
• Gear Oil Management: Change oil every 250-500 operating hours (250 hours in severe applications) and examine for metallic particles.
• Mounting Bolt Integrity: Always fit new high-strength bolts with thread locking compound torqued to factory specifications.
• Pre-Start Priming Procedure: Fill motor housing with clean hydraulic oil and run at low idle to purge air before heavy operational loads.
