In the work of the backhoe loader, it is inevitable to have such and other failures. Today, I will mainly introduce to you what we should do when we cannot correctly determine where the failure is.

Failure to correctly judge and analyze the failure of the backhoe loader, blindly dismantled and unloaded is commonplace

Some maintenance personnel were not clear about the structure and principle of the backhoe loader, did not analyze the cause of the fault carefully, and could not accurately determine the fault location. They blindly dismantled and unloaded the machinery based on the idea of "approximately, almost", and the result was that the original fault was not eliminated , And due to poor maintenance skills and craftsmanship, new problems have arisen.

When the backhoe loader fails, it must be detected by testing equipment. If there is no testing equipment, it can be determined by traditional fault judgment methods and means such as "ask, see, check, and test", combined with the structure and working principle of construction machinery. Determine where the failure is most likely to occur.

When judging the failure of a backhoe loader, the "removal method" and "comparative method" are generally used, and proceed in the order from simple to complex, appearance first, interior first, assembly first, and then parts. "
