Browning 3693934 Qd Bushed V-belt Sheave 2 Groove

Product Description

The BROWNING 3693934 is a two-groove, Quick Detachable (QD) bushed V-belt sheave designed for power transmission applications in HVAC, industrial, and mechanical drive systems. It features a 5.88-inch outside diameter and accepts bore diameters ranging from 5/8 inch up to 2-1/4 inches, accommodating a wide range of shaft sizes through a standard B-style QD bushing. Compatible with A, B, and 5V belt sections, this sheave delivers reliable torque transfer in blower, fan, and pump drive configurations. Installation is performed by licensed HVAC technicians, millwrights, and mechanical contractors as part of belt drive assembly and maintenance work.

This sheave is suited for use in residential and light commercial HVAC air handler and rooftop unit blower assemblies, as well as general industrial fan and pump drive systems. The QD bushing design allows the sheave to be mounted and removed without specialized pullers, making it practical for field service and scheduled maintenance. When specific compatible motor or blower shaft sizes fall within the 5/8 to 2-1/4 inch bore range, this sheave can be fitted with the appropriate B-style QD bushing to match the application.

Compatibility

Designed as an OEM-style replacement or aftermarket V-belt sheave for equipment using B-style QD bushed sheaves with a two-groove configuration and bore requirements between 5/8 inch and 2-1/4 inches.

Installation Notes

Installation should be performed by a qualified HVAC technician, millwright, or mechanical contractor. Disconnect and lock out all power to the drive system before removing or installing any sheave or belt components. Ensure the correct B-style QD bushing is selected to match the actual shaft diameter before mounting. Verify belt tension and sheave alignment with a straightedge after installation to prevent premature belt and bearing wear.
