Browning 1010685 Qd Bushed V Belt Sheave 3 Groove

Product Description

The BROWNING 1010685 is a three-groove, QD bushed V-belt sheave designed for use in belt-driven power transmission systems. The sheave features a 6.75-inch outside diameter and accepts bore sizes from 0.75 inches up to 2.6875 inches, accommodating a range of shaft sizes through a Q1-style quick-detachable bushing. With an A-section belt pitch diameter of 6.0 inches and a B-section belt pitch diameter of 6.4 inches, it is compatible with both A and B cross-section V-belts. Licensed HVAC, mechanical, and industrial service technicians install this component in fan, blower, and pump drive assemblies.

This sheave is suited for residential and light commercial HVAC blower systems, industrial fan drives, pump assemblies, and other belt-driven machinery requiring a multi-groove configuration. The QD bushing system allows the sheave to be mounted and removed without specialized tooling, making it practical for field replacement and preventive maintenance applications. Three grooves allow the drive load to be distributed across multiple belts, which is standard practice in higher-torque blower and fan installations.

Key Features

• Three-groove design distributes belt load across multiple V-belts for higher-torque drives
• 6.75-inch outside diameter suits common blower and fan drive configurations
• Q1-style QD bushing accommodates bore diameters from 0.75 inches to 2.6875 inches
• Compatible with both A-section and B-section V-belts via dual pitch diameters
• Quick-detach bushing design simplifies field installation and removal without special pullers

Compatibility

Designed as an OEM-style replacement sheave for belt-driven blower, fan, and pump drive systems using A-section or B-section V-belts with a Q1-style quick-detachable bushing.

Installation Notes

Installation and replacement of V-belt sheaves should be performed by a qualified mechanical or HVAC technician. Disconnect and lock out all power to the drive system before removing or installing any sheave or belt components. Verify shaft diameter falls within the 0.75-inch to 2.6875-inch bore range before selecting a bushing size, and torque bushing fasteners according to the bushing manufacturer specifications. Inspect belt tension and alignment after installation to prevent premature belt or bearing wear.
