Browning 3694205 3-groove Qd V-belt Sheave 5.68in Od

Product Description

The BROWNING 3694205 is a three-groove, quick-disconnect (QD) bushed V-belt sheave designed for industrial and commercial HVAC, fan, and blower drive applications. It accepts 5V, A, and B cross-section V-belts and features a 5.68-inch outside diameter with a 5.5-inch belt pitch diameter for 5V belts. The bore range runs from 0.625 inches minimum to 2.25 inches maximum, accommodating a wide range of shaft sizes via a B-style QD bushing. Cast iron construction provides the durability required for continuous-duty motor and fan drive systems. Licensed HVAC and mechanical contractors install this sheave as part of belt-drive assemblies on air handlers, rooftop units, and industrial blowers.

This sheave is suited for residential and commercial belt-drive systems where 5V, A, or B cross-section belts are specified. It is a common replacement or upgrade component on direct-drive conversions and motor-swap projects where shaft diameter changes require a new sheave. The B-style QD bushing design allows the bushing to be sourced separately to match the exact shaft diameter, making this a versatile stock item for HVAC and mechanical service shops. Three grooves support multi-belt drive configurations for higher horsepower transmission requirements.

Key Features

• Three grooves accommodate 5V, A, and B cross-section V-belts
• 5.68-inch outside diameter with 5.5-inch belt pitch diameter (5V)
• Bore range: 0.625 inches to 2.25 inches via B-style QD bushing (bushing sold separately)
• Cast iron construction for durability in continuous-duty drive applications
• Quick-disconnect bushing style simplifies installation and removal without specialty tools
• Multi-belt groove design supports higher horsepower transmission in HVAC and blower applications

Compatibility

Designed as an OEM-style replacement or new-installation sheave for belt-drive assemblies using 5V, A, or B cross-section V-belts where a B-style QD bushing and a 5.68-inch outside diameter sheave are specified.

Installation Notes

Installation is typically performed by licensed HVAC technicians or industrial mechanics. De-energize and lock out the motor at the disconnect before removing or installing any sheave or belt drive components, per NFPA 70E lockout/tagout requirements. The B-style QD bushing must be ordered separately and matched to the shaft diameter; verify shaft size and bushing bore before assembly. After installation, check belt tension and sheave alignment with a straightedge before restoring power to avoid premature belt and bearing wear.
