Pulley 1-V Yellow Zinc 2-3/8in OD

The Pulley 1-V Yellow Zinc 2-3/8in OD is a single-groove V-belt pulley engineered for light-duty automotive engine accessory drives. This component is essential for mechanics and enthusiasts working on serpentine belt systems, alternators, water pumps, and power steering assemblies. Yellow zinc plating provides reliable corrosion resistance in engine bay environments where moisture, heat cycling, and salt exposure are constant threats to bare iron.

Built with a 2-3/8 inch outer diameter and single V-groove design, this pulley is optimized for 1-V belt profiles—the industry standard for compact accessory drive systems. The yellow zinc coating offers superior adhesion and longevity compared to traditional zinc plating, reducing degradation under thermal cycling common in modern engine compartments. At 0.71 pounds, the compact form factor fits tight engine bay layouts without adding unnecessary mass, making it ideal for stock replacements and modified belt routing applications where space is constrained.

Mechanics restoring original engine functionality or upgrading to aftermarket serpentine systems will find this pulley compatible with most OEM and performance alternator, water pump, and idler installations. Installation is straightforward: simply slide the pulley onto the shaft, align the groove with adjacent pulleys for proper belt tracking, and secure with the original fastener. Whether you're performing routine maintenance or rebuilding a complete accessory drive system, the yellow zinc finish ensures years of corrosion-free operation without frequent replacement.
