Browning 3694072 Qd Bushed V-belt Sheave 2 Groove

Product Description

The BROWNING 3694072 is a two-groove, QD bushed V-belt sheave designed for power transmission applications in HVAC, industrial, and mechanical drive systems. It features a 12.68-inch outside diameter and accepts Quick Detach (QD) bushing style B, allowing bore sizes from 5/8 inch up to 2-1/4 inches. The sheave accommodates A, B, and 5V cross-section belts, making it a versatile choice for fan drives, blower assemblies, and pump systems. At 18.8 pounds, this is a substantial cast component suited for commercial and light industrial installations requiring reliable, low-maintenance belt drive operation.

This sheave is commonly installed in commercial HVAC air handling units, industrial blower drives, and centrifugal pump assemblies where a two-groove V-belt configuration is required. The QD bushing system simplifies installation and removal without the need for specialty pullers, making it a practical choice for service technicians performing routine drive replacements or system upgrades. It is appropriate for applications calling for 5V, A, or B section belts on shafts within the specified bore range.

Compatibility

Designed as an OEM-style replacement or new-installation sheave for two-groove V-belt drive systems using QD style B bushings and A, B, or 5V cross-section belts on shafts from 5/8 inch to 2-1/4 inches in diameter.

Installation Notes

Installation should be performed by a qualified millwright, HVAC mechanic, or power transmission technician. Disconnect and lock out all power to the drive system before mounting or removing the sheave. Ensure the mating QD style B bushing is properly seated and fasteners are torqued per the bushing manufacturer specifications. Verify belt alignment with a straightedge or laser alignment tool after installation to prevent premature belt and bearing wear.
