FAQ 

Q: What is the core function of 800302263 rear axle assembly?
A: It bears the total weight and loading impact of XCMG ZL50G/ZL50GL loader, reduces rotational speed and amplifies torque, and distributes power to two rear drive wheels, realizing walking and shoveling driving force for the machine.

Q: When does the rear axle assembly need to be replaced?
A: Replace the whole axle assembly when there is serious gear damage, big crack on axle housing, continuous heavy oil leakage, abnormal loud knocking noise that cannot be repaired, or serious deformation affecting driving safety.

Q: Can this rear axle assembly be installed directly on ZL50G / ZL50GL loader?
A: Yes, manufactured strictly according to XCMG original drawing, all installation dimensions, connecting bolt holes and interface parameters fully match the chassis, no cutting or welding modification required during installation.

Q: What are the daily maintenance points for the rear axle assembly?
A: Regularly check the gear oil level and oil quality, inspect for oil leakage at sealing positions. Replace gear oil following maintenance cycle; listen for abnormal noise during operation, and avoid long-time overload operation to protect internal gears and bearings.
