Fault diagnosis that bulldozer can't walk

First, the failure phenomenon:

There are two states in which the bulldozer cannot travel without a fault:

1. A chilly Dozer cannot walk. It usually means the chilly car starts the motor and runs at moderate speed. Then it's geared as well as the bulldozer can not begin instantly.

2. The heat engine can not walk. It usually means that the bulldozer grows increasingly more feeble as the oil temperature climbs during ordinary bulldozing, and it isn't easy to walk without loading.

Second, the fault diagnosis method:

After the Bulldozer is not able to travel, while it's in the cold or at the hot condition, the motor throttle ought to be controlled at moderate and higher speed, then the left foot pedal at the taxi ought to be disassembled to see if the output of the torque converter is rotating. Should you flip, examine the output after the equipment is still rotating. At precisely the exact same time, you ought to pay attention to if the noise of the motor, the torque converter as well as the transmission switch prior to and after the equipment.

So as to differentiate whether the petroleum process is faulty or automatically faulty, you are able to loosen the exhaust twist on the varying rate filter to find out whether there's air. When there's the atmosphere and it isn't exhausted, it usually means that the very low-pressure oil passage is involving the suction port and the variable rate pump. When there's air, it's demonstrated that the ingestion part is involving the petroleum suction day along with the strainer. It's common for steering and shifting.
