Browning 1001684 Qd Bushed V Belt Sheave 3 Groove

Product Description

The BROWNING 1001684 is a three-groove, QD bushed V belt sheave designed for power transmission applications in HVAC, industrial fan, pump, and blower drives. It accepts a P1-style Quick Detachable bushing, which allows fast installation and removal without special tools. The sheave has a 5.35-inch outside diameter, supports bore diameters from 0.5 inches up to 1.75 inches, and carries an A-section belt pitch diameter of 4.6 inches and a B-section belt pitch diameter of 5.0 inches. At 7.4 pounds, it is a solid, durable component suited for continuous-duty drive systems. HVAC mechanics and millwrights are the typical installers.

This sheave fits belt-driven systems where a three-groove drive is required to transmit load across multiple V belts simultaneously. Common applications include rooftop unit blower assemblies, centrifugal fans, commercial air handlers, and pump drives. The QD bushing system makes it practical for field installations where shaft alignment and sheave swaps need to be completed quickly. The bore range accommodates a variety of shaft diameters, making this sheave adaptable across multiple drive configurations without requiring a custom bore.

Installation Notes

Installation should be performed by a qualified HVAC technician or millwright. De-energize and lock out the drive system before removing or installing any sheave. Verify shaft diameter falls within the 0.5-inch to 1.75-inch bore range before ordering a bushing. Torque the QD bushing fasteners per the bushing manufacturer specifications, and check belt tension and sheave alignment after installation before returning the system to service.
