Product Description – XCMG Side Gear 275102466
The XCMG Side Gear 275102466 have genuine OEM differential component designed for the drive axle of XCMG wheel loaders, including models such as the XCMG ZL50GN, ZL50G, LW500KL, LW500F, and 500K series. This side gear (also known as a differential side gear or sun gear) is a precision-machined spiral bevel or straight-tooth gear that meshes with the differential pinion gears (spider gears) inside the differential carrier assembly. Its primary function is to transmit 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 turning or when traction varies between wheels.
Constructed from high-strength alloy steel, typically case-hardened (carburized or induction-hardened) to achieve a wear-resistant surface (58–62 HRC) with a tough, ductile core, the 275102466 side gear provides excellent fatigue strength, high impact resistance, and long service life under the extreme shock loads, high torque spikes, and continuous articulation encountered in quarrying, mining, construction, and material handling applications. The gear teeth are precision hobbed or ground to tight tolerances, ensuring smooth meshing, low noise, and efficient power transfer. The internal spline bore matches the corresponding axle shaft spline, providing secure torque transmission without backlash. An oil lubrication groove or cross-drilled hole may be incorporated for proper gear and bearing lubrication.
Direct interchange with the original factory side gear restores proper differential function, eliminates gear whine or clunking, prevents uneven tire wear, and avoids differential lock-up or axle failure. When replacing a side gear, it is strongly recommended to also inspect or replace the mating pinion gears, thrust washers, cross shaft, and axle shaft seals to ensure complete differential rebuild quality. Using an authentic XCMG side gear guarantees correct tooth profile, spline fitment, metallurgy, and heat treatment.
Applications: XCMG ZL50GN, ZL50G, LW500KL, LW500F, 500K, and other XCMG wheel loaders with XCMG or ZF-style drive axles that utilize the same differential side gear geometry.
