Browning 3694460 Qd Bushed V-belt Sheave 4 Groove

Product Description

The BROWNING 3694460 is a four-groove, QD bushed V-belt sheave designed for power transmission applications in HVAC, industrial, and mechanical systems. It features an outside diameter of 5.28 inches and accepts bore diameters ranging from 5/8 inch to 2-1/4 inch, accommodating a wide range of shaft sizes. The sheave uses a B-style QD bushing for repeatable, secure mounting and removal without damaging the shaft. Belt pitch diameters are 4.6 inches for A-section belts, 5.0 inches for B-section belts, and 5.1 inches for 5V-section belts. HVAC mechanics and millwrights install this sheave on blower assemblies, fan drives, and other belt-driven equipment.

This sheave is suited for residential and light commercial HVAC air handler and rooftop unit blower drives, as well as general industrial belt drive applications. The four-groove configuration allows multi-belt setups that distribute load and reduce individual belt stress. It is commonly installed on drives where A, B, or 5V cross-section belts are specified. The QD bushing system simplifies field replacement and realignment during scheduled maintenance or emergency service calls.

Installation Notes

Installation should be performed by a qualified HVAC technician or millwright. Disconnect and lock out all power to the drive system before removing or installing the sheave. Torque the QD bushing fasteners according to the bushing manufacturer specifications and verify sheave alignment with a straightedge before re-tensioning belts. Confirm belt cross-section compatibility before installation to avoid premature belt or sheave wear.
