1981 GL500 Silver Wing
I ordered a mechanical seal on ebay (yamaha part number 11H-12438-00). The inside diameter of the mint ring is 1mm smaller than the outside diameter of the thrust washer and the end of the camshaft. The impeller with the new mint ring in it is not making any contact with the mechanical seal (no springy action) and there is no thread coming out of the impeller to put the crush washer and acorn nut on. Do I just need to pony up for the factory $70 seal or did I order the wrong yamaha seal? I got the part number on a previous posts. A little help would be great, thanks!
