Gearbox of PD320Y Bulldozer
The machine is equipped with transmission of planetary gear and rotary lockup multi-disc clutch that are hydraulically engaged and force lubricated. Forward 3 speeds can be gained by actuating the hydraulic control valve.

Hydraulic Torque Converter of PD320Y Bulldozer
The torque converter is of the single stage , single phrase, 3 elements hydraulic type, with reasonable structure and excellent reliability, which provide optimum match with the machine. The centripetal turbine torque converter boasts unexampled superiority compared with traditional mechanical transmission, for example, it makes the machine have autoadaptation, stepless speed regulation, long lifetime, simplified operation, travelling comfort and torque-limiting capacity.

TY320 hydraulic torque converter is newly developed on the basis of Komatsu technology from Japan. It is created by employing better materials, improving production process and optimizing the layout of the device. Hence, the TY320 hydraulic torque converter features simple design, easy maintenance, low noise, and high reliability.

Final Drive of PD320Y Bulldozer
We at Pengpu are the first to master the technology in the manufacturing relief, crowned gear, which features heavy load large capacity, stable transmission and long life.

Power
1. The pulse vent-pipes improve emission and ensure superior performance of the engine.
2. High torque reserve, low speed under the maximum torque condition and strong adaptability.
3. High quality cast iron and specially designed valve guide pipes ensure good sealing performance and durability of the bulldozer.
4. Highly reinforced and balanced crankshaft, with precision design.
5. Advanced exhaust gas turbocharger.
6. Four valves per cylinder, increasing power and reducing fuel consumption of the bulldozer.
