Source1 2804761700 Variable Sheave 1 Groove 1.125 Inches Bore

Product Description

The SOURCE1 2804761700 is a variable sheave designed for use in commercial and residential HVAC systems. This single-groove sheave features a 1.125 inches bore and is built to OEM specifications, making it a direct-fit replacement for compatible York equipment. HVAC technicians rely on sheaves like this one to control the rotational speed of driven components such as blower wheels and fan assemblies. By adjusting belt drive ratios, a variable sheave allows technicians to fine-tune airflow and static pressure to meet system design requirements without replacing the entire drive assembly. This makes the 2804761700 a practical tool for balancing air distribution in air handling units, rooftop units, and other York HVAC equipment. The variable pitch design gives service professionals the flexibility to dial in the correct belt speed during commissioning or troubleshooting. This sheave is compatible with units including the 2EH04512058, 2HJ04502646, and 2HJ04601058 among others. Using genuine OEM replacement components like this sheave ensures a proper fit and helps maintain system efficiency over the long term. Aftermarket or mismatched sheaves can cause belt slippage, premature wear, and reduced airflow performance. The SOURCE1 2804761700 eliminates those concerns by delivering a part that meets the original manufacturer tolerances. It measures 6.1 inches in length, 6 inches in width, and 2.65 inches in height, with a shipping weight of 4.685 pounds. HVAC service professionals, maintenance crews, and facilities technicians working on York air handlers and package units will find this sheave to be a reliable and straightforward replacement option.
