Product Description – XCMG Side Gear 275102466 for ZL50GN Loader
The XCMG Side Gear 275102466 have genuine OEM differential component manufactured specifically for the XCMG ZL50GN wheel loader drive axle. This side gear (also referred to as a differential side gear or axle shaft drive gear) is a precision‑engineered, case‑hardened steel gear that meshes with the differential pinion gears (spider gears) inside the differential carrier. Its primary function is to transfer rotational torque from the differential case to the left or right axle shaft, while allowing the two drive wheels to rotate at different speeds during cornering or when traction varies between wheels – a critical requirement for loader maneuverability in tight construction sites, quarries, and material handling yards.
Manufactured from high‑quality alloy steel (typically 20CrMnTi or equivalent) and subjected to carburizing, quenching, and tempering heat treatment, the 275102466 side gear achieves a surface hardness of 58–62 HRC with a tough, ductile core. This metallurgical profile provides exceptional resistance to pitting, tooth breakage, and wear under the extreme shock loads, high torque spikes, and cyclic stresses encountered during bucket loading, aggressive digging, and travel over uneven terrain. The gear teeth are precision hobbed and ground to exacting tolerances (ISO class 6 or better) to ensure smooth meshing, low noise, and efficient power transfer. The internal spline bore is broached to match the corresponding axle shaft spline (typically 40 mm or similar, depending on the ZL50GN axle configuration), providing a secure, backlash‑free torque transmission.
The side gear 275102466 is a direct replacement for the original factory part in the XCMG ZL50GN drive axle (both front and rear axles, left and right sides). When installed together with new pinion gears, thrust washers, and cross shaft, it restores proper differential function, eliminates gear whine or clunking, prevents uneven tire wear, and avoids differential lock‑up or axle failure. Routine inspection of side gears is recommended during axle overhauls or whenever differential noise becomes apparent. Using an authentic XCMG side gear guarantees correct tooth profile, spline fitment, material grade, and heat treatment – essential for maintaining the ZL50GN's rated axle load capacity and operational reliability.
Applications: XCMG ZL50GN wheel loader – front and rear drive axles (differential assembly). May also fit other XCMG ZL50 series loaders (ZL50G, ZL50C) and LW500KL variants with the same axle architecture – always verify with original part number and axle serial number.
