Browning 1042423 Qd V Belt Sheave 1 Groove 3.95 in Od

Product Description

The BROWNING 1042423 is a quick-detachable (QD) bushed V belt sheave designed for single-groove power transmission applications. It accepts H-style QD bushings and accommodates bore diameters from 3/8 inch up to 1-1/2 inches, making it adaptable to a wide range of shaft sizes. The outside diameter measures 3.95 inches, with a belt pitch diameter of 3.2 inches for A-section belts and 3.6 inches for B-section belts. Cast iron construction provides durability under continuous load. HVAC technicians, millwrights, and mechanical contractors install this sheave on blower assemblies, fan drives, and general industrial drive systems where quick shaft mounting and removal are required.

This sheave is suited for both residential and commercial HVAC blower drives, industrial fan systems, and light-duty power transmission setups. It is compatible with A-section and B-section V belts. The H-style QD bushing mount simplifies installation and removal without requiring the shaft to be disturbed extensively, which is particularly useful during routine maintenance or belt replacement service calls in tight equipment spaces.

Installation Notes

Installation should be performed by a qualified mechanic or HVAC technician familiar with V belt drive systems. Disconnect and lock out all power to the drive system before removing or installing any sheave or bushing. Mount the H-style QD bushing to the shaft first and verify proper bore size match before drawing down the bushing fasteners evenly. Check belt tension and sheave alignment with a straightedge after installation before returning the system to service.
