Daikin 20655400 Fixed Sheave BK67H 6.45 Inch Od Single Groove

Product Description

The DAIKIN 20655400 is a fixed, single-groove bushed sheave designed for use in belt-drive fan and blower assemblies found in commercial HVAC systems. Manufactured to Browning BK67H specifications, it features a 6.45-inch outer diameter and accepts an H-style bushing for secure shaft mounting. The sheave is designed for use with B-section or 5L-section V-belts, with a 6.10-inch pitch diameter. HVAC technicians and mechanical contractors install this component on air handling units and rooftop units where reliable belt-drive power transmission is required.

This sheave is suited for belt-drive blower and fan applications in commercial and light industrial HVAC equipment. It is an OEM-replacement part for Daikin McQuay equipment, also cross-referencing to part numbers 206554X-00 and the Browning BK67H. Typical installation involves driven or driver sheave positions on blower shafts within air handling units, where precise pitch diameter is critical for maintaining correct fan speed and airflow performance.

Compatibility

Direct OEM replacement for Daikin McQuay equipment originally specifying part number 20655400 or 206554X-00. Also cross-references to the Browning BK67H sheave. Designed for use with B-section or 5L-section V-belts and H-series taper-lock bushings.

Installation Notes

Installation should be performed by a qualified HVAC technician or mechanical contractor. Disconnect and lock out all power to the unit before removing or installing sheaves. Use a proper sheave puller to remove the existing sheave without damaging the shaft, and ensure the H-style bushing is torqued according to the bushing manufacturer's specification. After installation, verify belt tension and sheave alignment before returning the unit to service.
