The supporting wheel of excavator carries the excavator's own quality and working load, and the property of the supporting wheel is an important standard to measure its quality. There are two reasons for the oil leakage of Komatsu excavator roller: first, the roller was immersed in water for a long time during the excavator operation, causing corrosion of the floating seal ring and O-ring groove; Second, construction in muddy water in winter resulted in ice formation and failure of floating seal ring.

During the work, try to avoid the Komatsu excavator roller from being immersed in muddy water for a long time. After the work is completed every day, the single-sided track shall be propped up and the traveling motor shall be driven to throw away the mud, gravel and other debris on the track.

During winter construction, the supporting wheel of Komatsu excavator must be kept dry, because there is a floating seal between the outer wheel and the shaft of the supporting wheel. If there is water, it will freeze at night. When the excavator is moved the next day, the seal will be scratched in contact with the ice, causing oil leakage.

The damage consequences of Komatsu excavator roller need to be judged according to the damage situation. Different damage causes may lead to different consequences. However, in order to ensure better use, we need to do a good job in daily inspection and maintenance to reduce the probability of damage.

Damage to the roller of Komatsu excavator will cause many failures, such as walking deviation and weak walking. Therefore, it is essential to pay attention to the maintenance of the roller.
