XCMG Coupling Sleeve 250100280 Z3.3-12A — OEM Drive Shaft Connector for LW300 3T Loader

Product Overview

The XCMG 250100280​ (Drawing No.: Z3.3-12A) is a genuine OEM coupling sleeve specifically designed for XCMG 3-ton class wheel loaders. As a critical component within the drivetrain system, this part is primarily used to connect the transmission output shaft to the drive shaft, ensuring the engine's power is transferred smoothly and efficiently to the drive axle.

Key Advantages

• Precision OEM Fit: Manufactured strictly according to XCMG's original engineering drawings, guaranteeing perfect dimensional tolerances with the stock drivetrain. Enables direct installation with no modifications required.

• High-Strength & Anti-Torsion: Forged from premium alloy steel, it is built to withstand high-torque impacts and cyclic loads under heavy-duty working conditions without deforming or fracturing.

• Wear-Resistant & Long-Lasting: Features precision-machined mating surfaces and specialized hardening treatment. This effectively minimizes mechanical clearance, reduces wear, and extends the overall service life of the drivetrain assembly.
