What are the specific signs of excessive wear on the dozer idler?

The specific signs of excessive wear on the dozer idler mainly include the following aspects:

Reduction in Structural Projection Width and Roller Surface Diameter: During normal operation, the dozer idler continuously contacts the roller surface of the track chain links, leading to friction and damage. Over time, the structural projection width and the roller surface diameter of the idler gradually decrease.

Lateral Movement and Increased Wear of Components: If the dozer idler is severely worn, the track may experience lateral movement, which not only causes further wear on the idler itself but also accelerates the wear of other components such as the track rollers, carrier rollers, and drive sprocket.

Excessive Roughness of the Axle Surface: If there are metal burrs on the surface of the dozer idler axle, it can disrupt the integrity and continuity of the lubricant film between the axle and the sliding bearing, leading to accelerated wear.

Damage and Burnt Bushings: In some cases, users may observe damage to the dozer idler, severe wear on the idler axle, and burnt bushings.
