Browning 3694361 3-groove Qd V-belt Sheave 13.88 in Od

Product Description

The BROWNING 3694361 is a three-groove, Quick Detachable (QD) bushed V-belt sheave designed for industrial and commercial HVAC belt-drive applications. It carries an outside diameter of 13.88 inches and accepts bore diameters ranging from 5/8 inch to 2-1/4 inches, giving installers flexibility when matching to a shaft size. The sheave is compatible with A, B, and 5V cross-section belts, with pitch diameters of 13.2 inches, 13.6 inches, and 13.7 inches respectively. At 28.4 pounds, this is a heavy-duty cast component suited for fan and blower drive assemblies where smooth, consistent belt engagement is required.

This sheave is used in belt-drive systems on commercial air handlers, centrifugal fans, blowers, and industrial machinery where multi-groove 5V or classical V-belt configurations are specified. The QD bushing design accommodates a Style B bushing, allowing fast mounting and removal without specialty tooling. It is a common choice for HVAC mechanical contractors and industrial maintenance technicians working on retrofit and new-installation drive assemblies.

Installation Notes

Installation should be performed by a qualified HVAC mechanic or industrial maintenance technician. De-energize and lock out the drive system before mounting or removing the sheave. The QD bushing must be sourced separately and torqued according to the bushing manufacturer specifications. Verify belt alignment and tension after installation before returning the system to service.
