Examine the surface of the track roller. If there are obvious scratches, grooves, or uneven wear—especially severe wear on the edges of the roller body—it indicates that the roller has been in use for a long time or is under uneven stress, and its quality may be poor.
Carefully check the surface of the track roller and the spoke area. Even tiny cracks can cause the track roller to suddenly fail during operation, affecting the normal operation of the excavator.
If there is extensive rust on the surface of the track roller, it will not only affect its appearance but also may weaken its strength and shorten its service life.
