Axle Overhaul and Broken Gear Repair: Trucks operating at construction sites and heavy-duty mining areas are often overloaded (50-80 tons), frequently starting on steep inclines or accelerating suddenly when stuck. This subjects the main reducer to enormous instantaneous impact loads. If the gears experience fatigue spalling or accidental tooth breakage, it can cause abnormal noise and seizure in the rear axle transmission. When disassembling a two-stage reducer, the 35-tooth gear is a core replacement component.

Differential Noise Reduction: When the rear axle gear oil is not changed for a long time, is low on oil, or has deteriorated in quality (mixed with metal shavings and dirt), severe abrasion and pitting can occur on the gear surfaces, causing a loud "humming" noise while the truck is in motion. In this case, the entire drive and driven gears must be replaced to restore the precise meshing of the drive shaft.

Foreign Trade B2B Bulk Container Procurement: In overseas regions such as Africa, the Middle East, and Southeast Asia, where infrastructure construction and mining are booming, Shaanxi Automobile and Sinotruk dump trucks have extremely high ownership rates. Due to the extremely poor road conditions and frequent overloading in mountainous areas, the wear and tear on the internal transmission components of these trucks is significantly higher than on highway vehicles. Therefore, these gears are a crucial chassis hardware component that overseas wholesalers consistently stock in large quantities, often in containers.
