Trane SHE00409 Bushed Sheave 2-groove Cast Iron Hvac

Product Description

The TRANE SHE00409 is a 2-groove bushed sheave designed for use in HVAC belt-drive blower and fan applications. Cast from iron for durability under continuous load, this sheave mounts to a drive shaft via a standard bushing interface with a 0.375-inch bore diameter. The outside diameter falls in the 11 to 15.9-inch range, and the unit weighs 17.54 pounds. Licensed HVAC technicians and mechanical contractors install this component as part of V-belt drive assemblies on air handling units and commercial fan systems where precise belt alignment and consistent rotational transfer are required.

This sheave is suited to residential and light commercial HVAC equipment that uses V-belt drive configurations on blower assemblies or supply fan sections. The 2-groove design accommodates dual-belt drive setups, which distribute load and reduce belt wear in higher-torque applications. It is also referenced by the alternate part identifier 2BK140H. Installation is typically performed during scheduled maintenance, belt replacement cycles, or after sheave wear inspection reveals out-of-spec groove profiles.

Key Features

• 2-groove design supports dual V-belt drive configurations for load distribution
• Bushed mounting style allows shaft fit adjustment and simplified removal
• Cast iron construction resists deformation under sustained rotational load
• 0.375-inch bore diameter for compatibility with standard drive shaft sizes
• Outside diameter range of 11 to 15.9 inches suits a range of drive ratio requirements
• Alternate part number 2BK140H for cross-reference identification

Compatibility

Designed as an OEM-style replacement sheave for TRANE HVAC systems using bushed 2-groove V-belt drive assemblies. Cross-referenced as 2BK140H.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified mechanical contractor. Disconnect and lock out all electrical power to the air handling unit before removing or installing any drive components. Verify belt tension and alignment with a straightedge after mounting the sheave to prevent premature belt or bearing wear. Follow applicable OSHA lockout/tagout procedures and local mechanical codes when servicing rotating drive components.
