Browning 3694452 Qd Bushed V Belt Sheave 4 Groove

Product Description

The BROWNING 3694452 is a quick-disconnect (QD) bushed V belt sheave engineered for multi-groove belt drive applications in HVAC, industrial fan, and pump systems. This four-groove sheave accepts A, B, and 5V profile belts and mounts via a B-style QD bushing for fast, repeatable installation and removal without special tooling. The outside diameter measures 5.08 inches, and the bore range spans 0.625 inches to 2.25 inches to accommodate a wide selection of shaft sizes. At 6.45 pounds, it is built for continuous-duty drive systems where alignment precision and groove consistency are critical to belt life.

This sheave is suited for commercial and light-industrial belt drive assemblies, including air handling units, centrifugal fans, blowers, and pump drive trains. HVAC mechanics and millwrights typically select this sheave when replacing worn OEM sheave components or configuring new drive systems that require a field-adjustable bore. The B-style QD bushing mount makes it compatible with standard B-series bushing bores across common shaft diameters within the stated range.

Compatibility

Designed as an OEM-style replacement or new-installation sheave for belt drive systems using A, B, or 5V profile V belts with a B-style QD bushing. Bore diameter is field-selectable between 0.625 inches and 2.25 inches via the appropriate B-series QD bushing insert.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified millwright. De-energize and lock out all power to the drive system before removing or installing any sheave or belt. Torque the QD bushing fasteners according to the bushing manufacturer specifications, and verify sheave alignment with a straightedge or laser alignment tool before tensioning belts. Ensure belt tension and drive geometry comply with applicable equipment manufacturer guidelines and OSHA machine guarding requirements.
