Not sure the proper name for this item. The flat washer with the little nib on the inside diameter that is used under the nut. Looking for a couple to make a proper and safe operation. Thanks.
you need model, type, and serial number of your machine. I think you are looking for a special keyed washer. the part number may be 904050106674 but you must confirm with model, type, & serial. Woodcraft or Klingspor may have them or you can go online to eReplacementparts.com
Another option is the washer on front spindles in cars. First you need to know spindle diameter, then truck down to a good auto parts store. They may be available in the "help section," or with some help from a sales person, just try a few makes. Correct name is Internal Tab Washer. Agrisupply over in Greenville should have some in the section where trailer spindles and bearings are located.
