Product Overview
3862917 Accessory Drive Shaft (SHAFT,ACCESSORY DRIVE) is a core power transfer component for Cummins series diesel engine accessory drive system. It transmits rotational power to drive auxiliary assemblies, ensuring synchronous operation of related engine accessories.
This accessory drive shaft solves typical faults such as shaft journal wear, spline damage, torsion deformation, power transmission jitter and abnormal knocking caused by fatigue and overload damage of old drive shafts.
Core Product Advantages
High-Strength Alloy Steel Blank & Heat Treatment
Integrated alloy steel forging with quenching and tempering process, outstanding torsional strength and impact resistance, resistant to twisting deformation under continuous heavy torque load.
Precision Journal & Spline Machining
Shaft journal and transmission splines undergo fine grinding, strict dimensional tolerance, good matching with bearings and driving wheels, minimize abrasion and transmission clearance.
Strict Dynamic Balance Calibration
Precision dynamic balance correction, effectively lower high-speed vibration, reduce load on supporting bearings and extend service life of the whole accessory drive system.
Excellent High & Low Temperature Stability
Stable mechanical performance within -40℃ ~ +135℃, no thermal deformation under long-term high-temperature environment in engine compartment.
Anti-Corrosion Surface Protection
Surface passivation anti-rust treatment, resist erosion of engine oil, moisture and dust, prevent journal rust and seizure.
Standard Matching Installation Specification
Dimension 23cm18cm18cm, weight 8.496KG, perfectly match Cummins engine accessory drive assembly, plug-and-play replacement without secondary machining.
Multi-Item Factory Inspection
All shafts pass torsion fatigue test, hardness inspection, dimensional verification and flaw detection, stable batch quality for engine overhaul factories and transport fleets bulk procurement.
