FAQ 

Q1: Is this rear propeller shaft 252900465 compatible with both ZL50G and ZL50GL?
A1: Yes. This propeller shaft is customized for XCMG ZL50G and ZL50GL wheel loaders. Shaft length, flange specification and universal joint size are universal for the two models.

Q2: What typical symptoms indicate that the rear propeller shaft needs to be replaced?
A2: Obvious abnormal knocking and vibration during acceleration and shoveling; serious wear or seizure of universal joint cross; cracks on shaft tube or flange; spline severe wear with large gap; power cut-off caused by shaft fracture.

Q3: What routine maintenance should be carried out for rear propeller shaft?
A3: Regularly check shaft tube for cracks and deformation; inspect universal joint for looseness and abnormal clearance; add lithium base grease to grease nipple according to maintenance cycle; check tightness of flange connecting bolts; avoid long-time overload operation.

Q4: Is dynamic balance and torque test carried out before delivery?
A4: Every propeller shaft will pass dynamic balance inspection and torsion load test before leaving factory to guarantee stable performance under rated torque.

Q5: What precautions should be taken during propeller shaft installation?
A5: Mark original assembly position before disassembly to keep phase angle of universal joint; clean flange contact surface and remove dirt and rust; replace old lock washers; tighten flange bolts to specified torque; after installation, test run and check for abnormal vibration and noise.

Q6: Can we only replace the cross joint instead of the whole propeller shaft?
A6: If only cross shaft and bearing are damaged while shaft tube, spline and flange are intact, cross joint can be replaced separately. But if shaft tube cracks or splines are severely worn, the whole shaft assembly must be replaced.
