37B-22-11410 Final Drive Unit for Komatsu CK20-1 CK25-1 Compact Track Loader Travel Motor Gearbox Spare Parts

The Final Drive Unit (37B-22-11410) is the high-torque hydraulic propulsion assembly engineered specifically for the Komatsu CK20-1 and CK25-1 Compact Track Loaders (CTL). This critical undercarriage component integrates a high-efficiency axial piston motor with a multi-stage planetary gearbox to deliver the superior tractive effort, precise maneuvering, and durability required for landscaping, site preparation, and utility construction.

Restoring Mobility to the Komatsu CK Series The Komatsu CK20-1 and CK25-1 are versatile workhorses known for their compact footprint and agile performance. The 37B-22-11410 Final Drive is the mechanical core that translates hydraulic flow into the tractive force needed to navigate mud, loose soil, and steep grades. Whether you are backfilling a trench or grading a residential lot, this drive ensures your tracks have the synchronized power to operate with zero "tracking fade."

As these loaders often work in abrasive environments, the final drives are subjected to intense external debris and internal pressure. Our premium aftermarket units are built with high-strength forged housings and induction-hardened gears to resist the structural fatigue common in high-cycle construction. Replacing your worn unit with our precision-engineered assembly restores factory-standard speed and drawbar pull, protecting your project's productivity.

• High Power Density: The compact motor design provides massive torque output without increasing the machine's overall width, maintaining the CK series' slim profile for confined space work.

• Direct "Plug-and-Play" Fitment: Manufactured to the exact dimensional standards of Komatsu 37B-22-11410, ensuring all hydraulic ports and sprocket mounting holes align perfectly for a fast installation.

• Advanced Planetary Gearing: Multi-stage gear reduction using high-strength alloy steel ensures uniform load distribution and minimizes internal friction.

• Heavy-Duty Sealing: Equipped with premium floating seals and O-rings to prevent gear oil leakage and protect internal components from external contamination.

The Komatsu CK series remains a popular choice in various international markets, and our drive assemblies are optimized for these diverse environments:

• North America & Europe: Ideal for the "Landscaping" and "Snow Removal" sectors where machines must shift frequently between high-torque pushing and rapid transport on paved or frozen surfaces.

• Southeast Asia & Oceania: Features reinforced floating seals to protect internal gears from the ingress of abrasive volcanic sand, tropical mud, and high humidity common in coastal work sites.

• Middle East & Africa: Optimized for high thermal resilience in the hydraulic motor section, preventing seal hardening and oil degradation during long hours in high-ambient desert temperatures.

• Latin America: Engineered to maintain hydraulic efficiency and consistent torque in rugged rural infrastructure and agricultural support tasks.
