2T268500110 37C-22-11410 Final Drive for Komatsu CK30-1 CK35-1 Heavy-Duty Compact Track Loader Travel Motor & Gearbox

The Final Drive Unit (2T268500110 & 37C-22-11410) is the high-torque hydraulic powerhouse engineered for the Komatsu CK30-1 and CK35-1 Compact Track Loaders (CTL). As the primary driver for these large-frame loaders, this assembly combines a high-displacement axial piston motor with a rugged multi-stage planetary gearbox to deliver the massive tractive effort and precision control required for heavy-duty earthmoving, forestry, and site development.

Restoring Peak Breakout Force The Komatsu CK30-1 and CK35-1 are high-performance machines designed for the toughest tasks. The 2T268500110 Final Drive is the mechanical heart that converts hydraulic energy into the massive drawbar pull required to push through heavy debris, grade steep slopes, or operate high-flow attachments like mulchers and brush cutters.

If your machine is "wandering" to one side or struggling to climb trailers, your final drive is likely experiencing internal pressure bypass. Our premium 37C-22-11410 replacement ensures that both tracks receive synchronized power, restoring that "factory-fresh" responsiveness to your joysticks and significantly reducing operator fatigue.

• 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.

Regional Application & Market Suitability

The Komatsu CK heavy series is a global workhorse, and our drive assemblies are optimized for the following markets:

• North America (USA & Canada): Optimized for the Forestry and Land Clearing sectors. Our drives are built to withstand the high vibration and constant shock loads of mulching heads and grapple buckets.

• Australia & Oceania: Features reinforced "Heavy-Duty" floating seals to protect internal gears from the abrasive red dust and sandy soils common in the Outback and civil construction sites.

• Europe: Meets the demand for high-precision grading and urban infrastructure work, offering smooth shifting between high-speed transport and low-speed, high-torque work modes.

• Southeast Asia: Engineered with anti-corrosive coatings and enhanced sealing to prevent moisture and mud ingress in tropical, high-humidity environments.

A final drive for a machine this size is an investment. Protect it by watching for these common "red flags":

• • The "Silent Killer" (Case Drain Pressure): On Komatsu CTLs, the case drain line must be clear. If this line is blocked by debris, internal pressure will spike and blow the main motor seal. Always inspect your case drain filters during installation.

  • Oil Color Check: Change the planetary gear oil every 500 hours. If the oil looks "milky," water has breached the seals. If it contains metal flakes, a planetary gear is failing. Catching this early can save you from a total breakdown.

  • Sprocket Bolt Maintenance: Due to the high torque of the CK35, sprocket bolts can stretch. Always use new grade-8 bolts and a high-strength thread locker to prevent flange damage.

  • Purging the Air: After installing the 37C-22-11410, run the tracks off the ground for 10 minutes at low idle. This purges air from the hydraulic motor and prevents "dry-start" cavitation.
