Common faults and solutions of chassis components in construction machinery

Excavators and bulldozers, operating under heavy loads and harsh working conditions for extended periods, are prone to various malfunctions in their chassis components. Many users, unaware of the root causes of these failures, blindly replace components, leading to wastage. Liutui Machinery has summarized the common causes of high-frequency malfunctions and provided professional solutions for swift and targeted treatment.

Oil leakage and jamming of track rollers: These issues are often caused by aging oil seals, sediment infiltration, and wear of the shaft sleeve. Solutions: Replace with high-quality track rollers with good sealing, perform routine cleaning, and avoid prolonged exposure to muddy water operations.

Excessive wear and skipped teeth of drive gears: improper tension of the track, mismatch of machine models, insufficient material hardness; Solutions: replace with quenched drive gears of an appropriate model, adjust the tension of the track, and use high wear-resistant alloy steel components.

Track fracture and derailment: Worn chain pin shafts, failed tension springs, and damaged carrier rollers; Solutions: Replace the track assembly and tension spring, regularly check the operating status of the carrier roller, and promptly replace aging components.

Deformation and deviation of the guide wheel: long-term heavy and unbalanced load operations, insufficient material toughness; solution: replace with original factory-grade compatible guide wheels, standardize equipment operation, and avoid long-term unilateral heavy-load construction.
