Browning 1001676 Qd Bushed V Belt Sheave 2 Groove

Product Description

The BROWNING 1001676 is a two-groove, quick-detachable (QD) bushed V-belt sheave designed for industrial and mechanical drive applications. Built from cast iron, it features an outside diameter of 5.35 inches and accepts a P1-style QD bushing with bore sizes ranging from 1/2 inch to 1-3/4 inches. The sheave is compatible with 5V, A, and B section V-belts, with a belt pitch A diameter of 4.6 inches and a belt pitch B diameter of 5.0 inches. HVAC and mechanical service technicians install this type of sheave on blower and fan drive assemblies where variable speed or belt replacement is required.

This sheave suits commercial and residential HVAC air handler drives, industrial fan assemblies, and general-purpose power transmission systems. The QD bushing design allows fast, precise mounting and removal without specialized tooling, making it a practical choice for equipment rooms where downtime must be minimized. It is typically found on belt-driven blower assemblies in rooftop units, air handling units, and industrial ventilation equipment where two-groove drive configurations are standard.

Installation Notes

Installation should be performed by a qualified HVAC technician or mechanical drive specialist. Disconnect and lock out all power to the drive system before removing or installing any sheave or bushing. Ensure the QD bushing is properly seated and fastening hardware is torqued according to the bushing manufacturer specifications before returning the drive to service. Verify belt tension and alignment after installation to prevent premature wear.
