Lubrication problem of loader running in period

Lubrication during running in period

Due to the small fitting clearance between the new assembled parts and the assembly and other reasons, it is difficult to ensure the uniformity of the fit gap. It is difficult for the lubricating oil (grease) to form a uniform oil film on the friction surface to prevent wear and tear. Thereby reducing lubrication efficiency, resulting in early abnormal wear of parts. In severe cases, it will result in scuffing or occlusion of the friction surface, resulting in failure.
