Komatsu PC40MR-2 PC50MR-2 Final Drive Assembly | Travel Motor 22M-60-21301

The 22M-60-21301 Travel Motor Assembly is an advanced locomotion system specifically manufactured for Komatsu PC40MR-2 and PC50MR-2 compact excavators in the 4-5 ton weight category. This heavy-duty unit combines a variable displacement hydraulic motor with a rugged reduction gearbox, delivering exceptional traction and extended longevity for demanding earthmoving tasks.

Because these Komatsu minimum-radius excavators operate worldwide, our travel assemblies are customized to overcome specific environmental challenges:

• North America & Europe: Optimized for residential and landscaping markets, offering quiet operation and rapid responsiveness in confined urban job sites.
• Southeast Asia & Oceania: Equipped with upgraded mechanical face seals to withstand heavy moisture and highly abrasive terrain common in tropical climates.
• Japan & East Asia: Calibrated to synchronize flawlessly with original factory hydraulic flow protocols, ensuring precise and delicate maneuvering.

• Zero-Tail Swing Optimized: Specifically profiled to accommodate the tight clearance requirements characteristic of the MR (Minimum Radius) series excavators.
• OEM System Synchronization: Perfectly matches factory hydraulic pressures and flow rates to maximize tractive effort and climbing ability.
• Ruggedized Housing: Cast from premium steel alloys to endure severe impacts and bearing loads during tough trenching conditions.
• Plug-and-Play Installation: Hose connections and mounting flanges align identically with original blueprints for rapid, straightforward swap-outs.

• Hydraulic Fluid Integrity: Routinely inspect return filters and maintain low case drain pressure to protect internal rotating groups.
• Lubrication Schedules: Drain and replace the reduction gear lubricant every 300 to 500 hours, carefully monitoring for metallic debris.
• Mounting Hardware Care: Secure the track sprocket using fresh fasteners applied with industrial-grade thread sealant to avoid detachment.
• Pre-Operation Priming: Strictly pre-fill the motor cavity with specified hydraulic fluid prior to initial startup to prevent catastrophic dry friction.
