1. Backhoe Loader Wears Fast

Due to the influence of the processing, assembly and adjustment of the parts of the new Backhoe Loader equipment, the friction surface is rough, the contact area of the mating surface is small, and the pressure bearing condition of the surface is uneven. During the operation of the equipment, the concave-convex parts of the part surface are embedded and friction with each other, and the worn metal debris continues to participate in the friction as abrasive, which further accelerates the wear of the fitting surface of the part. Therefore, during the running-in period, it is easy to cause the wear of parts (especially the mating surface), and the wear speed is fast. At this time, if the operation is overloaded, it may cause damage to parts and early failure of the loader.

2. Poor Lubrication

Due to the small fitting clearance of the parts assembled by the new Backhoe Loader, various operation modes and natural conditions, it is difficult to ensure the uniformity of the fitting clearance, and the lubricating oil (grease) is not easy to form a uniform oil film on the friction surface to prevent wear. This will reduce the lubricating efficiency and cause early abnormal wear of the machine parts. In serious cases, the friction surface of precision fitting will be scratched or ablated, resulting in failure.

3. Loose

The newly processed and assembled parts of Backhoe Loader have deviations in geometric shape and fit size. At the initial stage of use, due to the impact, vibration and other alternating loads, as well as the impact of heat, deformation and other factors, as well as the rapid wear and other reasons, it is easy to make the originally fastened parts loose.

4. Leakage

Due to the looseness and vibration of Backhoe Loader parts and the influence of heat on the equipment, the sealing joint surface and pipe joints of the equipment will leak, and some defects such as casting and processing are difficult to find during assembly and commissioning. However, due to the vibration and impact during the operation, such defects will be exposed, which is manifested as oil (water) leakage. Therefore, leakage is easy to occur during the running-in period.

5. Many Operation Errors

Because the Backhoe Loader operator does not know enough about the structure and performance of the equipment (especially the new operator), it is easy to cause failures due to operation errors, even mechanical accidents due to rough operation; Or do not adapt to the operation mode and habits of different brands of equipment.
