The part name decodes as an input gear with a 28-tooth count, 8.0482 diametral pitch, and a 20-degree pressure angle with 23 as a secondary identifier, all characteristics that determine gear mesh compatibility within the PTO assembly. Selecting the correct input gear requires matching tooth count, pitch, and pressure angle to the existing PTO drive train. Pro Gear and Transmission carries genuine Chelsea parts.
