Product Overview
3883324 Accessory Drive Pulley (PULLEY,ACCESSORY DRIVE) is a key transmission pulley matched for Cummins series diesel engine accessory drive system. It cooperates with multi-wedge belt to transmit crankshaft power, driving generator, water pump and other auxiliary equipment to operate normally.
This accessory drive pulley solves common faults such as belt slipping, sharp squealing, groove surface wear, pulley eccentricity and auxiliary equipment insufficient power caused by aging and abrasion of old pulleys.
Core Product Advantages
High-Strength Cast Alloy Integral Forming
High-rigidity cast material, strong impact and vibration resistance, not easy to deform or crack under long-term high-speed rotation.
Precision Multi-V Groove Machining
Smooth and accurate pulley grooves fit the belt perfectly, increase contact area, reduce slipping risk and improve transmission efficiency.
Dynamic Balancing Treatment
Strict dynamic balance calibration, minimize vibration during high-speed operation, reduce bearing load and extend service life of related components.
Excellent Heat Dissipation & Temperature Resistance
Optimized structural design accelerates heat dissipation; stable performance under -40℃ ~ +135℃, no thermal deformation in engine compartment.
Anti-Corrosion Surface Treatment
Surface anti-oxidation coating resists engine oil, dust and humid air erosion, effectively prevent rust and groove abrasion.
Standard Matching Specification
Dimension 15cm4cm15cm, weight 0.925KG, perfectly match Cummins engine installation position, direct replacement without modification.
Strict Factory Quality Test
All pulleys pass dynamic balance inspection, dimensional tolerance test and wear test, stable batch quality for engine overhaul and fleet bulk procurement.
