Browning 3694080 Qd Bushed V Belt Sheave 2 Groove

Product Description

The BROWNING 3694080 is a two-groove, Quick Detachable (QD) bushed V-belt sheave designed for industrial and commercial drive applications. Manufactured from cast iron, it features a 13.88-inch outside diameter and accepts a bore range of 5/8 inch to 2-1/4 inch using a B-style QD bushing, which is sold separately. The sheave is compatible with 5V, A, and B cross-section V-belts, giving it broad application across HVAC blower drives, compressor drives, and general mechanical power transmission systems. At 22.7 pounds, this is a heavy-duty component intended for professional installation on commercial or industrial equipment.

This sheave is well suited for belt-driven HVAC air handling units, centrifugal fans, pump drives, and compressor assemblies in both commercial and light industrial settings. The QD bushing design allows for straightforward installation and removal without special pulley pullers, making it a practical choice for service technicians and mechanical contractors who need reliable, repeatable positioning on motor or driven shafts. The two-groove configuration supports dual V-belt drive arrangements common in higher-load blower and fan applications.

Key Features

• Two-groove design accommodates dual V-belt drive configurations for increased load capacity
• Accepts 5V, A, and B cross-section V-belts for broad drive system compatibility
• QD B-style bushing mount allows fast installation and clean removal without special tooling
• 13.88-inch outside diameter suits common commercial blower and fan drive setups
• Bore range of 5/8 inch to 2-1/4 inch fits a wide variety of motor and driven shaft sizes
• Cast iron construction provides durability in continuous-duty drive environments

Compatibility

Designed as an OEM-style replacement or upgrade sheave for two-groove V-belt drive systems using B-style QD bushings and 5V, A, or B cross-section belts. Bushing is not included and must be sourced separately.

Installation Notes

Installation should be performed by a qualified mechanical or HVAC technician familiar with belt drive systems. Disconnect and lock out all power to the drive system before mounting or removing the sheave. Torque the QD bushing fasteners according to the bushing manufacturer specifications, and verify sheave alignment with a straightedge or laser alignment tool before tensioning belts. Improper alignment or over-tensioning can cause premature belt and bearing wear.
