Browning 1042688 Qd V Belt Sheave 1 Groove 14.75 in Od

Product Description

The BROWNING 1042688 is a single-groove, quick-disconnect (QD) bushed V-belt sheave designed for use with A and B section V-belts in industrial and commercial mechanical drive applications. Built from cast iron, it features a 14.75-inch outside diameter and accepts an H-style QD bushing with a bore range of 0.375 inches to 1.5 inches, allowing field selection of the correct shaft fit without purchasing a new sheave. The belt pitch diameter is 14.0 inches for A-section belts and 14.4 inches for B-section belts. At 10.05 pounds, this sheave suits a wide range of fan, blower, pump, and compressor drive configurations.

This sheave is commonly installed in HVAC fan drive systems, industrial blower assemblies, pump drive packages, and compressor applications where a QD bushing mount is specified. The H bushing style makes it compatible with standard H-series tapered bushing bores. It is suited for both new installations and replacement of worn or damaged sheaves in existing belt drive systems across light commercial and industrial settings. Mechanical contractors and HVAC technicians are the primary installers in trade environments.

Installation Notes

Installation should be performed by a qualified mechanical or HVAC technician. Disconnect and lock out all power to the drive system before removing or installing any sheave or bushing. Ensure the mating H-style QD bushing is sourced separately and matches the shaft diameter before assembly. Follow the bushing manufacturer's torque sequence for the bushing cap screws, and verify belt tension and sheave alignment with a straightedge or laser alignment tool after installation.
