Browning 3694551 Qd Bushed V Belt Sheave 4 Groove

Product Description

The BROWNING 3694551 is a quick-detachable (QD) bushed V belt sheave designed for industrial and commercial power transmission applications. This four-groove sheave accepts multiple V belt profiles, including A, B, and 5V belts, making it a versatile component in blower, fan, and pump drive systems. The outside diameter measures 7.08 inches, and the bore accepts shafts ranging from 5/8 inch up to 2-1/4 inches when fitted with a compatible QD bushing. At 13.85 pounds, it is built for durability in continuous-duty installations. HVAC service techs and industrial mechanics are the primary installers for this type of sheave.

This sheave is commonly used in belt-driven HVAC systems such as air handling units, centrifugal fans, and commercial blowers where precise belt alignment and reliable torque transfer are required. The QD bushing mount system allows for straightforward installation and removal without specialty tooling, which reduces service time on belt changes and seasonal maintenance. The four-groove configuration supports multiple belt runs for higher load capacity in demanding drive arrangements.

Compatibility

Designed as an OEM-style replacement or direct upgrade for belt-driven fan, blower, and pump systems requiring a four-groove QD bushed sheave with a 7.08-inch outside diameter and bushing style B mount.

Installation Notes

Installation and removal should be performed by a qualified mechanic or HVAC technician. Disconnect and lock out all power to the drive system before beginning work. Ensure the correct QD bushing size and style B are selected separately to match the shaft diameter before mounting. Align the sheave with a straightedge or laser alignment tool after installation and verify belt tension according to the belt manufacturer specifications before returning the unit to service.
