Browning 1002344 Qd Bushed V Belt Sheave 3 Groove

Product Description

The BROWNING 1002344 is a quick-detachable (QD) bushed V belt sheave designed for power transmission applications in HVAC, industrial, and mechanical drive systems. This three-groove sheave accepts A and B section V belts and mounts via a Q1-style QD bushing, allowing fast installation and removal without damage to the shaft. The outside diameter measures 7.75 inches, the belt pitch A diameter is 7.0 inches, and the belt pitch B diameter is 7.4 inches. Bore diameter range runs from 0.75 inches minimum to 2.6875 inches maximum, accommodating a wide range of shaft sizes. Licensed HVAC technicians and mechanical contractors install this component in blower drive assemblies and fan systems.

This sheave is suited for use in commercial and residential air handling units, induced-draft blowers, cooling tower fans, and general-purpose belt-drive systems where a three-groove configuration is required. The Q1 QD bushing interface is standard across a broad range of blower and motor shaft configurations, making this sheave a common replacement in existing drive assemblies. It is installed wherever matched A-section or B-section V belt sets are specified by the equipment manufacturer.

Installation Notes

Installation and removal should be performed by a qualified technician. De-energize and lock out the motor and disconnect power before servicing any drive assembly. The QD bushing must be installed and torqued per the bushing manufacturer's standard procedure using appropriate hand tools. Inspect all V belts for wear and replace matched belt sets as a complete set to maintain proper tension and alignment across all three grooves.
