Browning 3694197 3-groove Qd V-belt Sheave 5.48in Od

Product Description

The BROWNING 3694197 is a three-groove, quick-disconnect (QD) bushed V-belt sheave designed for industrial belt-drive systems in HVAC, refrigeration, and mechanical equipment applications. The sheave accepts B-style QD bushings and accommodates bore diameters ranging from 5/8 inch to 2-1/4 inch, giving installers flexibility across a range of shaft sizes. The outside diameter measures 5.48 inches, with a belt pitch diameter of 5.3 inches for 5V-profile belts. Weighing 6.45 pounds, this cast sheave is suited for fixed or variable-speed drive installations where accurate pulley alignment and secure bushing retention are required.

This sheave is used in belt-drive assemblies on commercial and residential HVAC air handlers, blowers, exhaust fans, cooling towers, and other rotating equipment where multi-groove V-belt drives are specified. The three-groove configuration supports higher torque transmission and redundant belt arrangements. It is typically installed by HVAC technicians, millwrights, or mechanical contractors during new installations or as a direct replacement in existing drive systems.

Compatibility

Designed as an OEM-style replacement or new-installation sheave for three-groove QD bushed belt-drive systems using B-style quick-disconnect bushings and A, B, or 5V-profile V-belts.

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 sheaves. The QD bushing must be fully seated and fasteners tightened in the correct sequence per the bushing manufacturer's torque pattern before returning the drive to service. Verify belt tension and sheave alignment with a straightedge or laser tool after installation to prevent premature belt and bearing wear.
