Engine The engine is DIESEL ENGINE C6121ZG57 that is manufactured byShanghai diesel engine works. Optional engines are Cummins engines(NT855-280S10), Caterpillar engines(C3306) depends on customers requires. 2.Torque converter The torque converters are of the single stage, single phrase, 3 elements hydraulic type with reasonable structure and excellent reliability, which provide optimum machines. the outstanding transmissions comparing to the normal ones means the automatic adjustment to the field condition, gradually speed change,improved machine lifetime and traveling ability, easy maintenance, improved working comfort and torque limit set protection function. 3. Final drive For tip relieve and crowned gears which features large loading capacity, stable transmission and long lifetime 4. Transmission, hydraulic parts, undercarriage and working equipment Inter-changeable with same products of Komatsu as well as those products that are produced according to Komatsu technology. 5. Braking system It is single-leg braking system, which means when a single leg stamps on pedal, the braking band both right & left working in the same time. The kind technology also occupy leading position in China. 6. Electronic monitoring system The 3-stage alarming & monitoring system is mounted in cabin, which can measure and monitor voltage, oil pressure, water temperature, oil temperature, engine speed. It also can monitor the status of fuel oil, cooling water and the condition of air filter. By the twinkling of light and buzzing of horn, the system can inform drivers the essential information of bulldozer and assure bulldozers working in normal, safe and high efficiency condition. There are also engine oil pressure gauge and water temperature gauge in the instrument panel to make parameters visible and own two-tier protection function. 7. Shanghai-PD165Y bulldozer is equipped with good looking hexahedron cabin with wide visual scope. ROPS and FOPS can be mounted at the option of customers. 8. Shanghai-PD165Y bulldozer has the outstanding advantage of low fuel-consumption, strong draw power, high reliable, easy to operate and safe, comfortable. The machine has be greatly approved by specialist in construction mechanical industry.
