XCMG 860165916 Wheel Loader Front Axle Main Reducer Assembly
● XCMG 860165916 Main Reducer Technical Support
● Part number 860165916 (interchangeable with catalog numbers 275102523, 275102485, and DA1170C-3) is the genuine heavy-duty front drive axle spiral bevel main reducer and differential carrier assembly manufactured for XCMG 5-ton wheel loaders.
● Material number 860165916 is installed centrally inside the DA1170 front axle housing, receiving rotational drive power from the front transmission propeller shaft. Through a high-precision matched spiral bevel drive pinion and crown ring gear set (8:37 reduction ratio) paired with an internal 4-planetary differential, it changes power flow 90 degrees and multiplies drive torque before sending traction through the axle half-shafts to the wheel hub planetary final drives.
● Check axle gear oil level and viscosity regularly, inspect drive pinion seal integrity, and ensure proper bevel gear backlash during scheduled axle rebuilds to prevent premature gear tooth pitting under severe quarry breakout loads.
