Product Description
22H-60-13112 Final Drive for Komatsu PC50 PC55 PC56 PC56-7 | 5-6 Ton Travel Motor Gearbox
The Final Drive Assembly (P/N 22H-60-13112) is the high-efficiency propulsion unit engineered for Komatsu’s utility excavator range. Optimized for the PC50, PC55, and PC56 (including the PC56-7) series, this unit integrates a 2-speed axial piston motor with a precision planetary reduction gearbox. Designed for the 5.0 to 6.0-ton machine class, it provides the ideal balance of site mobility and the high tractive effort needed for trenching, backfilling, and light demolition.

Professional Product Overview
Precision Tracking for High-Production Site Work The Komatsu PC56 and PC56-7 are among the most popular utility excavators globally, prized for their reliability in tight urban job sites. However, the final drive—located at the lowest point of the machine—is constantly subjected to mud, water, and extreme torque loads. If your machine is "veering" to one side or struggling to turn in soft soil, your 22H-60-13112 unit is likely losing volumetric efficiency.
Our replacement units are manufactured to handle the specific hydraulic flow and pressure curves of the Komatsu closed-center system. Built with induction-hardened gears and high-load bearings, this assembly eliminates "tracking drift" and ensures your machine maintains synchronized travel. Replacing a worn drive with our precision assembly restores the factory-standard breakout force and the nimble counter-rotation ability Komatsu is known for.
Regional Application & Market Suitability
-
These Komatsu utility machines are global staples, and our drives are optimized for:
-
North America & Europe: Ideal for the Rental and Utility sectors. Built to handle the high duty cycles of fiber optic trenching and urban road maintenance.
-
Southeast Asia & China: Specifically engineered to survive in high-intensity Infrastructure and Agricultural projects where machines often work in deep mud or high-salinity coastal environments.
-
Australia & Oceania: Features reinforced mechanical floating seals to prevent the ingress of abrasive sandy soils and dust, extending the life of the internal gearbox.
-
Key Features & Performance Advantages
-
Compact High-Torque Design: Specifically engineered to fit the narrow undercarriage of the PC50/PC56 series without sacrificing necessary drawbar pull.
-
Seamless 2-Speed Integration: Fully supports Komatsu’s automatic high/low speed shifting logic, allowing for fast transit across the site and high-torque power when digging.
-
Forged Gearbox Housing: Unlike cheaper cast versions, our housings are forged from high-strength alloy steel to resist structural cracks under heavy lateral loads.
-
Direct "Plug-and-Play" Fitment: All hydraulic port locations (Main A/B, Case Drain, and Pilot) match the original Komatsu piping layout for a fast, hassle-free installation.
Expert Maintenance Guidance
-
The "Silent Killer" (Case Drain Pressure): Komatsu utility machines are sensitive to return-line backpressure. Before installing a new motor, ensure the case drain line is clear. A blockage here will blow the shaft seal of your new 22H-60-13112 motor almost instantly.
-
Gear Oil Management: Change the planetary gear oil every 500 operating hours. Check the oil for a "milky" appearance frequently—this indicates water ingress that will quickly grind down your planetary gears.
-
Sprocket Bolt Maintenance: These machines generate significant vibration during travel. Always use new Grade 10.9 or 12.9 bolts and a high-strength thread locker to prevent the sprocket from working loose and damaging the drive flange.
-
System Priming: Never run a new travel motor "dry." Fill the motor case with clean hydraulic oil through the highest drain port before installation to ensure instant lubrication.
