As the construction equipment, bulldozers can save a lot of material and human resources, accelerate the speed of road construction and reduce the progress of the project. However, in daily work, some faults often occur due to improper maintenance of equipment or lost years. Now I will make a specific analysis of these causes with you:

The bulldozer cannot be started: after normal use and parking, it cannot be started again and discharged smoke-free. Through the starter can work normally, the preliminary judgment of the fault is on the oil road. When using the manual pump for oil, the pump is sufficient, and there is no air in the oil flow, and the manual pump can also work quickly. It indicates that the oil supply is normal, and the oil circuit has no blockage phenomenon, and no air leakage. If the machine is newly purchased soon, the injection pump (lead seal) is less likely to fail. Finally, I observed the flameout pull rod, and found that it was not in the normal position and started normally after hand moving. Determine the fault is on the solenoid valve. After replacing the solenoid valve, the engine works normally, and the fault can be eliminated.
