The pulley with drive plate and cap is available as a replacement part (single part number). The pulley and the drive plate are held together by a bolt (bolt is not required; can be disposed of). This bolt is used during manufacturing to insert a pre-determined amount of a specific grease into the thread of the drive plate (sufficient for fitting the drive plate onto the compressor shaft once; do not re-use a drive plate that has been unscrewed)
