- Adopt thick seamless alloy steel pipe and forged alloy steel cross shaft. After multiple heat treatment procedures, it balances high hardness and excellent toughness, withstands repeated peak torque impact under heavy loads, effectively prevents torsional deformation and shaft fracture faults.
- Precision spline sliding pair delivers reliable axial length compensation. It absorbs frame deformation and displacement caused by rear axle swing during operation, reduces extra stress on transmission components and extends service life of the whole transmission system.
- Finished with high-precision dynamic balance calibration, suppress vibration and abnormal noise during torque transfer, reduce impact load on rear drive axle, and protect expensive core transmission components.
- Equipped with standard grease fitting, convenient for on-site periodic lubrication maintenance, reduces wear of cross shaft and bearings and extends the service cycle of the propeller shaft.
- Complete supporting accessories including flange bolts and lock washers are supplied together. One-piece delivery simplifies spare parts procurement, convenient for on-site maintenance and rapid replacement.
- Optimized universal joint swing angle design, adapts to swing movement of rear axle during loader operation, ensures smooth and stable power transmission, lowers impact load on rear axle main reducer and reduces failure probability of rear axle assembly.

FAQ 

Q1: Is this rear propeller shaft 252100665 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: What precautions should be taken during propeller shaft installation?
A4: 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.

Q5: What is the main reason for fracture of propeller shaft tube?
A5: Common reasons include long-time overloading, impact collision, loose flange bolts, out-of-balance of the shaft assembly, universal joint stuck, fatigue crack expansion after long service time.
