WA470-7 Wheel Loader

Large Capacity Lock-Up Torque Converter

The Komatsu-designed power train features a large capacity torque converter for optimum efficiency. The large capacity torque converter allows the loader to up-shift gears faster for improved acceleration and hill climbing ability. In most applications, production is increased and fuel consumption is reduced, resulting in improved fuel efficiency.
