Browning 1002401 3TB80 Qd Bushed V Belt Sheave 3 Groove

Product Description

The BROWNING 1002401 is a 3-groove, QD bushed V-belt sheave designed for power transmission applications in HVAC, industrial, and mechanical systems. Manufactured from iron, this sheave accepts a Q1-style quick-disconnect bushing, which allows for secure shaft mounting and straightforward removal during service. The outside diameter measures 8.35 inches, with a belt pitch A diameter of 7.6 inches and a belt pitch B diameter of 8.0 inches. The bore range spans 3/4 inch to 2-11/16 inch to accommodate a variety of shaft sizes. Licensed HVAC and mechanical contractors rely on this type of sheave for blower and fan drive assemblies where precise belt alignment and reliable torque transfer are required.

This sheave is suited for use in commercial and residential HVAC air handling units, industrial blower drives, and general power transmission systems where 5V, A, or B section V-belts are specified. The 3-groove configuration supports multi-belt drive setups, distributing load evenly across the belt set. It is appropriate for both new installations and replacement of worn or damaged sheaves in existing drives where a Q1 bushing style and comparable outside diameter are required.

Compatibility

Compatible with 5V, A, and B section V-belts. Designed for use with Q1-style QD bushings. Suitable as an OEM-style replacement sheave in HVAC blower and fan drive assemblies requiring a 3-groove sheave with an 8.35-inch outside diameter.

Installation Notes

Installation is typically performed by licensed HVAC technicians or qualified mechanical contractors. Disconnect and lock out electrical power to the drive system before removing or installing the sheave. Ensure the Q1 bushing is correctly seated and fasteners are evenly tightened before restoring power. Verify belt tension and sheave alignment with a straightedge or laser alignment tool after installation to prevent premature belt and bearing wear.
