Browning 3694056 2 Groove Qd Bushed V Belt Sheave

Product Description

The BROWNING 3694056 is a two-groove, Quick Detachable (QD) bushed V-belt sheave designed for industrial HVAC, fan, and blower drive applications. It features a 9.68-inch outside diameter with belt pitch diameters of 9.5 inches for 5V belts, 9.4 inches for B belts, and 9.0 inches for A belts. The sheave accepts a B-style QD bushing and accommodates bore diameters from 5/8 inch up to 2-1/4 inches, providing flexibility across a range of shaft sizes. Cast iron construction delivers durability in demanding mechanical drive systems. HVAC technicians and millwrights commonly install this component in air handling units, commercial rooftop equipment, and industrial blower assemblies.

This sheave is suited for two-belt drive configurations using 5V, A, or B cross-section V-belts. Its QD bushing design allows for straightforward installation and removal on standard shaft sizes within the specified bore range. Typical applications include commercial and industrial fan drives, centrifugal blower assemblies, and pump drive systems where a two-groove sheave arrangement is specified. The B-style bushing mount makes field replacement efficient without specialized tooling beyond standard hand tools.

Installation Notes

Installation should be performed by a qualified mechanic or HVAC technician. Disconnect and lock out all power to the drive system before servicing. The QD bushing must be installed per the bushing manufacturer's torque procedure; do not fully tighten fasteners until the sheave is properly aligned with the mating sheave. Verify belt tension and sheave alignment with a straightedge or laser alignment tool after installation to prevent premature belt and bearing wear.
