Browning 1043041 Qd Bushed V Belt Sheave 2 Groove

Product Description

The BROWNING 1043041 is a two-groove, QD bushed V belt sheave designed for industrial and commercial HVAC blower and fan drive applications. It features an H-style quick-disconnect bushing mount, allowing for fast installation and removal without special pulley pullers. The sheave has a 5.45-inch outside diameter, accommodates A-section and B-section V belts, and accepts bore diameters ranging from 3/8 inch to 1-1/2 inch. At 4.6 pounds, it is a solid cast component suited for motor-to-blower drive systems where reliable belt tension and concentricity are critical to system performance.

This sheave is commonly used in rooftop units, air handling units, and belt-drive blower assemblies found in both light commercial and residential HVAC equipment. It is appropriate for any application requiring a two-belt drive configuration using standard A or B cross-section V belts. HVAC technicians and mechanical contractors typically specify this sheave during blower drive replacements, fan speed corrections, or system upgrades where matched belt pairs and proper sheave geometry are required.

Key Features

• Two-groove design supports dual V belt drive configurations for balanced load distribution
• H-style QD bushing mount enables tool-accessible installation and removal on the shaft
• Wide bore range from 3/8 inch to 1-1/2 inch accommodates common motor and blower shaft sizes
• Compatible with A-section belts (4.7-inch belt pitch diameter) and B-section belts (5.1-inch belt pitch diameter)
• 5.45-inch outside diameter suitable for standard HVAC blower drive ratios

Compatibility

Designed as an OEM-style replacement or upgrade sheave for belt-drive blower and fan assemblies using H-style QD bushings and standard A or B cross-section V belts. No specific model compatibility was provided in the product data.

Installation Notes

Installation and removal should be performed by a qualified HVAC technician or millwright with experience in belt-drive systems. Disconnect and lock out all electrical power to the unit before servicing the drive assembly. The H-style QD bushing must be torqued to the shaft using the bushing's threaded jackscrew holes per standard QD bushing procedures. Always inspect belt tension and sheave alignment after installation to prevent premature belt and bearing wear.
