Browning 3693736 Qd Bushed V-belt Sheave 1 Groove 7.68 in Od

Product Description

The BROWNING 3693736 is a single-groove, Quick-Detachable (QD) bushed V-belt sheave designed for use in industrial and commercial drive systems. It accepts 5V, A, and B cross-section belts, with a 7.5-inch belt pitch diameter for 5V belts, a 7.0-inch pitch diameter for A-section belts, and a 7.4-inch pitch diameter for B-section belts. The outside diameter measures 7.68 inches. Bore range spans 5/8 inch minimum to 2-1/4 inch maximum, accommodating a variety of shaft sizes. The sheave uses a B-style QD bushing (sold separately) for straightforward installation and removal without specialized bearing pullers. Cast iron construction gives it durability in demanding drive applications.

This sheave is suited for single-groove V-belt drive arrangements in HVAC equipment, fans, blowers, compressors, pumps, and general industrial machinery. The QD bushing system makes it a practical choice for equipment that requires periodic belt or sheave service. It is installed by licensed HVAC technicians, millwrights, and mechanical contractors working on belt-driven systems in both light commercial and industrial environments.

Installation Notes

Installation and removal should be performed by a qualified mechanic or licensed HVAC technician with the drive system fully de-energized and locked out per OSHA lockout/tagout procedures. The QD bushing is not included and must be ordered separately to match the required shaft diameter. Verify belt cross-section and pitch diameter requirements before installation to ensure proper belt tension and alignment. Do not overtighten bushing cap screws beyond the bushing manufacturer's published specifications.
