Daikin 804000 Split Taper Bushing 1-1/4 in Bore

Product Description

The DAIKIN 804000 is a split taper bushing designed for use in commercial HVAC and mechanical drive applications. Split taper bushings provide a secure, concentric mounting method for sheaves, sprockets, and pulleys onto shafts. This bushing features a 1-1/4 inch bore and is manufactured to OEM specifications, making it a direct-fit replacement for worn or damaged original components. Licensed HVAC mechanics and mechanical contractors are the typical installers for this type of drive component.

This bushing is used in belt-drive systems found in commercial air handling units, fan coil units, and rooftop equipment where positive shaft-to-sheave engagement is required. The split taper design allows the bushing to be installed and removed without damaging the shaft or sheave, simplifying routine maintenance on drive assemblies. This part replaces OEM part number 00804000.

Ensure the shaft and bushing bore are clean and free of burrs before seating the bushing. Do not over-tighten set screws beyond the sheave or bushing manufacturer guidance, and verify belt tension and sheave alignment after installation.
