318805111 pulley XCMG XE2000 excavator spare parts

XCMG XE2000 excavator pulley 318805111 High-efficiency drive

In the power transmission system of the XCMG XE2000 excavator, the pulley transfers engine power to auxiliary systems, ensuring operation of the alternator, water pump, and air compressor. The pulley with part number 318805111 delivers stable power transfer, withstands heavy loads, and maintains reliability in harsh construction environments.

Efficient Power Transmission​

The 318805111 pulley optimizes power transfer to XE2000 auxiliary systems. Its precision-machined groove design ensures secure belt grip, minimizing slippage under high torque. This efficient transfer provides consistent power to components at idle or full load, reducing energy loss and enhancing auxiliary system efficiency for reliable cooling and electrical generator operation.​

High-Strength Construction​

Made from high-grade alloy steel, the pulley withstands heavy loads and continuous operation. Its robust structure resists deformation and wear from belt tension, rotational forces, and vibration. Heat and corrosion-resistant coatings handle high temperatures and exposure to dust, moisture, and debris, ensuring durability and reducing premature failure risks.​

Precision Balancing​

Rigorous precision balancing ensures smooth rotation at high speeds, minimizing vibration transfer to the engine and auxiliaries. This reduces noise and extends the life of belts, bearings, and moving parts while enhancing operator comfort by lowering cabin vibrations during prolonged use.​

Optimized Groove Design​

The pulley’s groove profile matches XE2000 drive belt specifications, distributing tension evenly to prevent uneven wear. This reduces friction, extends belt life, lowers maintenance costs, and prevents slippage that causes overheating and failure, ensuring reliable power transmission.​

Seamless Integration​

Tailor-made for the XE2000, its mounting dimensions, shaft interface, and grooves match engine and auxiliary requirements for hassle-free installation. Proper alignment and tension are maintained, allowing quick assembly or replacement with minimal downtime.​

Environmental Resistance​

Corrosion-resistant coatings protect against rust, while heat resistance handles engine temperatures. A sealed design prevents debris accumulation, maintaining smooth rotation in muddy, dusty, or wet conditions for consistent performance across diverse sites.​

For XE2000 operators, reliable auxiliary power is critical. The 318805111 pulley’s efficiency, strength, balance, and durability ensure consistent power delivery. Choose it to keep your excavator’s systems operating reliably on every project.
