See the commonly used digging machine errors, some maintenance personnel can not accurately determine the fault location, with "probably almost" thinking big blind dismantling mechanical unloading, the result not only of the original fault is not excluded, and the emergence of new problems. 1 Nissan Komatsu bulldozers, diesel power shortage occurs, the fault is not working machinery, maintenance personnel disassemble the PT fuel pump and injectors did not find cause of the malfunction where to sell used excavators, replace a fuel pump test, the fault persists . Finally, check the fault is due to the diesel internal impurities, caused by too much water, and this has led to the demolition PT fuel pump performance degradation, lack of engine power. When the mechanical failure of large Excavators price, to be detected by the testing equipment to determine the most likely site of failure. In determining engineering mechanical failure Excavators, commonly used "exclusion" and "comparison", in order from simple to complex, inside after the first appearance, the first order and then part of the assembly were, should "do not ask indiscriminate, blind large dismantling unloading. " Mistakes also a personal habit, as long as attention, according to the normal method of operation on it. Visceral is more important than appearance, see Excavators not be fooled by its beautiful appearance, good equipment, key components are more important, look at a used excavator equipment Do not let the appearance of this piece of equipment affect your judgment, regardless of What looks to be a closer look at its internal. Some devices (particularly short time) may be due to the owner not understand, driver technology not spoil the appearance of being very serious, but it does not out too much force; some devices may look glamorous, may have been established over the contribution painstaking a.
