Used Genuine Gear 3-Piece Set for 10 Stella C2000HGS Compatibility: 1000S, C2000S, C2000HGS This is a gear set that came with a used Stella I purchased. I'm selling it because I don't use it (cleaned). I don't think there are any scratches on the gear meshing parts. The pinion gear has slight traces of dirt. Note: I cannot determine the gear's smoothness. Please check the images and make your own judgment before purchasing. No returns or exchanges.
