9. Self-check generator with avalanche diode and self-driven adjustor for excellent reliability.
10. Reinforced oil pan for less noise radiation. Service hours of CH grade oil: 500h.
Gear Box
Hydraulic controlled gearshift is realized by operating the control valve, and without having to stop the machine,when operated with the torque converter to save operator effort.
The transmission is combined with four planets lines and a rotary lock-up clutch, multiple disc clutch, hydraulic controlled release, forced lubrication, with 3 speeds forward and 3 speeds backward.
Torque Converter
The hydraulic torque converter for is a newly developed product with the improvement made to the material, process and layout based on introduced Japan KOMATSU technology. It features simple architecture, easy maintenance, low noise, excellent reliability, stepless speed regulating which ensure perfect match to the machine for an outstanding traction and a stable transmission.
The Final Driving
The final drive uses triangle Spline and tip relief, crowned gear drive for enhanced balance and the stability during power transmission, lower noise, excellent reliability and added life.
