Browning 3695228 Qd Bushed V Belt Sheave 2 Groove

Product Description

The BROWNING 3695228 is a two-groove, Quick Detachable (QD) bushed V belt sheave designed for industrial and commercial HVAC blower and fan drive applications. It accepts a P1-style QD bushing and accommodates bore diameters from 0.5 inches up to 2.4375 inches, giving technicians flexibility across a range of shaft sizes. The outside diameter measures 4.68 inches, with a belt pitch A diameter of 4.0 inches, a belt pitch B diameter of 4.4 inches, and a belt pitch 5V diameter of 4.5 inches. Two grooves allow for dual V belt configurations that deliver reliable power transmission in belt-driven fan and blower assemblies. Weighing 4.05 pounds, this sheave is a standard replacement or new-install component for HVAC and mechanical drive systems.

This sheave is suited for residential and commercial HVAC systems where belt-driven blowers, fans, or air handlers require a compact, dual-groove pulley. The QD bushing system simplifies installation and removal on motor or driven-shaft ends without specialty tooling. It is commonly installed by HVAC technicians and millwrights during motor replacements, drive upgrades, or routine belt-drive maintenance. The P1 bushing style is a widely used QD standard, making this sheave a practical fit for many existing belt drive setups.

Installation Notes

Installation should be performed by a qualified HVAC technician or millwright. Disconnect and lock out all power to the motor before removing or installing any sheave or belt drive component. The QD bushing must be torqued to the bushing manufacturer specifications using appropriate fasteners — do not overtighten or substitute hardware. After installation, verify belt tension and sheave alignment with a straightedge or laser alignment tool before returning the system to service.
