Browning 3694619 4-groove Qd V-belt Sheave 9.68 in Od

Product Description

The BROWNING 3694619 is a four-groove, Quick Detachable (QD) bushed V-belt sheave designed for industrial and commercial HVAC blower and fan drive applications. It accepts a B-style QD bushing and accommodates bore diameters ranging from 5/8 inch to 2-1/4 inches, giving installers flexibility across a range of shaft sizes. The outside diameter measures 9.68 inches, with a 5V belt pitch diameter of 9.5 inches. At 19.35 pounds, this is a substantial cast sheave built for continuous-duty belt drive systems. Licensed HVAC mechanics and millwrights typically specify this part for air handler, fan coil, and rooftop unit blower assemblies where reliable torque transfer is critical.

This sheave is suited for residential and light commercial HVAC equipment, industrial fans, and blower systems that run 5V cross-section V-belts in a four-groove configuration. The QD bushing mount simplifies installation and removal on driven shafts, making it a practical choice for service situations where downtime must be minimized. The wide bore range also makes it adaptable to replacement scenarios where the original sheave and shaft dimensions vary across equipment vintages.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified millwright. Disconnect and lock out all electrical power to the drive system before removing or installing any sheave or belt components. Confirm the B-style QD bushing matches the driven shaft diameter before tightening fasteners, and verify belt alignment and tension according to the belt and drive manufacturer specifications after installation. Refer to applicable mechanical and HVAC codes for drive-system service requirements.
