Processing Standard：OEM original drawing standard
Feature：High torsion resistance, strong impact resistance, length compensation function, low vibration, stable operation, long service life

- Strictly produced in accordance with OEM drawing specifications, consistent with original mounting dimensions. Plug-and-play installation, no modification required, greatly shortens equipment maintenance downtime.
- Adopt thick seamless alloy steel pipe and forged alloy steel cross shaft. After multiple heat treatment processes, it achieves high hardness and good toughness balance, capable of enduring frequent peak torque impact under heavy-load working conditions, effectively preventing torsional deformation and shaft breakage.
- The precision spline sliding pair provides reliable axial length compensation. It absorbs frame deformation and displacement generated during operation, reduces additional stress on transmission parts and extends the service life of the whole drive system.
- Finished with high-precision dynamic balance calibration. It suppresses vibration and abnormal noise during torque transmission, reduces shock load to the front drive axle and gearbox, and protects expensive core transmission components.
- Equipped with standard grease fitting design. Users can perform regular lubrication maintenance conveniently to reduce wear of cross shaft and bearings and prolong the service cycle of the propeller shaft.

FAQ 

Q1: Is this front propeller shaft 252102173 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 front 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 front 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 hazards will occur if flange bolts are loose for a long time?
A5: Loose bolts will cause the shaft to shake during operation, resulting in flange cracking, universal joint damage, even shaft breakage, sudden loss of power and machine shutdown.
