If it is plastic inspect closely where the shaft comes through the gear as there will generally be a hairline crack and the gear must fit tight. $25.00 Select a style: M10 tooth count M11 tooth count M12 tooth count M13 tooth count M14 tooth count M15 tooth count M16 tooth count M17 tooth count M18 tooth count M19 tooth count M21 tooth count M25 tooth count M29 tooth count
