Browning 1001742 Qd Bushed V-belt Sheave 3 Groove

Product Description

The BROWNING 1001742 is a three-groove, quick-detachable (QD) bushed V-belt sheave designed for industrial and HVAC belt-drive applications. It features a 5.55-inch outside diameter and accepts bore sizes from 0.5 inches up to 1.75 inches, making it adaptable to a range of shaft sizes through a P1-style QD bushing. The sheave carries a Belt Pitch A diameter of 4.8 inches and a Belt Pitch B diameter of 5.2 inches, supporting both A-section and B-section V-belt configurations. Weighing 8.05 pounds, this sheave is suited for blower, fan, and pump drive assemblies where precise belt alignment and repeatable installation torque are required.

This sheave is commonly installed in commercial and residential HVAC air handling units, industrial blower assemblies, and pump drive systems. It is appropriate wherever a three-groove, QD-bushed sheave in the 5.55-inch OD class is specified. The P1 QD bushing interface allows fast installation and removal without the need for specialized pullers on most applications. HVAC mechanics and millwrights are the primary trades that install this component during new equipment commissioning or belt-drive servicing.

Key Features

• Three-groove design supports multiple V-belt configurations for higher torque transmission
• 5.55-inch outside diameter suits compact drive system layouts
• Bore range of 0.5 to 1.75 inches accommodates various shaft sizes via P1 QD bushing
• Belt Pitch A diameter of 4.8 inches and Belt Pitch B diameter of 5.2 inches for A-section and B-section belt compatibility
• QD bushing style simplifies installation and future sheave removal
• Weighs 8.05 pounds, indicating substantial cast construction for durability in continuous-duty service

Compatibility

Designed as a QD bushed replacement sheave for three-groove V-belt drive systems requiring a P1 bushing style and an outside diameter of approximately 5.55 inches. Specific system compatibility depends on the mating bushing, shaft diameter, and belt section selected for the drive.

Installation Notes

Installation should be performed by a qualified HVAC technician or millwright. Disconnect and lock out all electrical power to the drive system before removing any belt guards or sheaves. The P1 QD bushing must be ordered separately if not already on hand; confirm bushing bore matches the shaft diameter before assembly. Verify belt tension and sheave alignment with a straightedge after installation to prevent premature belt and bearing wear.
