Applicable Models

Suitable for XCMG ZL50G and ZL50GL wheel loader, can directly replace original connecting shaft with the same part number.

Application Scenarios

Widely used in earthmoving, quarry, sand yard, road construction and mining heavy-duty working scenarios, realizing stable torque transfer between transmission assemblies of XCMG ZL50G / ZL50GL loader.

• Adopt forged alloy steel raw material, high overall density, excellent torsional performance, resist alternating torque impact during continuous loader loading operation.
• Integral quenching & tempering heat treatment, uniform material hardness, effectively reduce spline wear and extend service life under cyclic load.
• Precision spline and flange machining, high assembly coaxiality, reduce vibration and noise during power transmission.
• Magnetic particle inspection for every finished shaft, detect tiny cracks to avoid sudden shaft fracture on construction site.
• Strictly produced according to XCMG OEM drawings, spline size and mounting hole spacing match perfectly for ZL50G/ZL50GL, convenient for field replacement.
• Reasonable structural design, allow small angular misalignment, buffer instantaneous impact torque and protect adjacent transmission components.

FAQ 

Q: What is the main function of 252100666 connecting shaft?
A: It connects different transmission assemblies of XCMG ZL50G/ZL50GL loader, transmits torque from power source to the executing parts, realizes stable power transfer and ensures normal walking and shoveling actions.

Q: When do I need to replace this connecting shaft?
A: Replace it immediately if shaft body has visible cracks, spline tooth serious abrasion, torsion deformation, obvious bending or abnormal rattling noise that appears during power transmission. Even small cracks found during inspection must be replaced to prevent sudden breakage under heavy load.

Q: Can this connecting shaft install directly on ZL50G / ZL50GL loader?
A: Yes, manufactured strictly according to XCMG original drawing, spline specification, flange dimension and installation hole position fully match the original assembly, no secondary modification required.

Q: What maintenance tips for the connecting shaft?
A: Regularly check shaft surface, splines and bolt fastening status; inspect for cracks, corrosion and spline wear. Keep the lubrication of matching spline pair, avoid long-time overload operation and reduce impact load during shoveling.
