Product Introduction:
The 75201275 side gear (also referred to in some catalogs as a half shaft gear) is a differential component used in Meritor drive axles fitted to XCMG ZL50G series wheel loaders. It is the gear that engages with the spider gears inside the differential assembly and transfers torque to the axle shaft.
1. Installation Location
This side gear is installed inside the differential assembly of the drive axle. It sits in the differential case, meshing with the spider (pinion) gears, and is splined to the axle shaft that drives the wheel.
2. Function
The side gear transmits rotational torque from the differential spider gears to the axle shaft, driving the wheel. Together with the opposing side gear, it allows the left and right wheels to rotate at different speeds during turns while still receiving engine power, which is essential for stable loader operation on uneven ground.
3. Maintenance and Service
Regular inspection includes checking the gear teeth for pitting, scoring, or excessive wear, and verifying the spline fit to the axle shaft. If the differential produces abnormal noise, shows excessive backlash, or the gear teeth are damaged, the side gear should be replaced. Differential assembly requires correct bearing preload and backlash adjustment, and should be performed by qualified technicians.
4. Important Notes
Always verify the part number 75201275 matches the original component specification for the specific Meritor axle configuration on the ZL50G loader before installation. Confirm compatibility with the corresponding XCMG reference number where applicable. Use the specified axle lubricant and maintain the correct oil level after assembly.
