Browning 1001973 Qd Bushed V Belt Sheave 2 Groove

Product Description

The BROWNING 1001973 is a two-groove, quick-disconnect (QD) bushed V belt sheave designed for power transmission applications in HVAC, industrial, and mechanical drive systems. It accepts a P1-style QD bushing and accommodates bore diameters from 0.5 inches to 1.75 inches, giving technicians flexibility when matching shaft sizes in the field. The outside diameter measures 6.35 inches, with a belt pitch A diameter of 5.6 inches and a belt pitch B diameter of 6.0 inches. Cast from iron, this sheave delivers the rigidity and wear resistance required for continuous-duty belt drive service. Installation is handled by licensed HVAC technicians, millwrights, or mechanical contractors.

This sheave is suited for residential and light commercial HVAC blower assemblies, fans, pumps, and general industrial drive systems where A, B, or 5V belt sections are specified. The two-groove configuration supports dual-belt drive setups, which are common in higher-torque or redundancy-sensitive applications such as supply fan assemblies and induced-draft blowers. The P1 QD bushing interface allows for straightforward shaft mounting and removal without specialty tooling beyond a standard hex key set and torque wrench.

Key Features

• Two-groove design supports A, B, and 5V belt trade sizes
• P1-style QD bushing interface for secure, removable shaft mounting
• Bore range of 0.5 to 1.75 inches accommodates a wide variety of shaft diameters
• 6.35-inch outside diameter with 5.6-inch belt pitch A diameter and 6.0-inch belt pitch B diameter
• Iron construction for durability in continuous-duty drive applications

Compatibility

Designed as an OEM-style replacement or upgrade sheave for two-groove V belt drive systems using A, B, or 5V belt sections with a P1 QD bushing. Verify shaft diameter falls within the 0.5-inch to 1.75-inch bore range before ordering.

Installation Notes

Installation should be performed by a qualified HVAC technician, millwright, or mechanical contractor. De-energize and lock out the equipment per NFPA 70E procedures before removing the existing sheave or bushing. Inspect belts and mating sheave for wear before reassembly, and verify belt tension and sheave alignment after installation to prevent premature wear or vibration. Do not exceed the specified bore range when selecting a bushing for this sheave.
