Why genuine parts

Komatsu Powertrain components are critical to the high-level performance, productivity, efficiency and reliability of equipment. In machines like dozers, graders and wheel loaders, where the efficient delivery of engine power to the ground is essential, we have developed unique and unrivalled transmission technologies to deliver industry-leading responsiveness, speed and durability.

These include our Torqflo power shift dozer transmission system, dual power shift/lockup torque converter auto grader transmissions and fourth-generation hydrostatic drives on wheel loaders. Combined with Komatsu final drives and differentials, these efficiently convert torque to traction, ensuring your Komatsu machine operates productively under the most challenging ground conditions in widely varying environments.

All Komatsu powertrain elements are designed and manufactured to work together with optimum efficiency. It’s crucial that you use genuine Komatsu components, parts, consumables and lubricants to get the best from your equipment.

Every piece of Komatsu equipment depends on its hydraulic system to operate productively, efficiently and reliably at the lowest cost per metre of material moved. We design and manufacture the most advanced, efficient and reliable hydraulic system available.

For example, the unique closed-centre hydraulic system used on Komatsu excavators and other equipment continues to set the industry standard, combining ease of operation, versatility, fine control and precision operation of multiple functions with low fuel consumption. Komatsu hydraulic components are built to the highest tolerances, which is why it’s critical that you use genuine Komatsu parts, consumables and lubricants. That way, you can be sure of long, reliable and productive life from your Komatsu equipment.
