Hi there im rebuilding an fzr250r 3ln1 engine and the seal on the end of the crankshaft needs to be replaced and appears to be no longer available. Its part number 2 on the diagram. The one on my engine has a locating flange on it and a groove cut in the crankcasae to accept it. However they give 2 part numbers for that seal and one doesnt have the flange. Im wondering if the cases were all the same and they can be used interchangably. The part number of the non flanged seal is 93101-28153 and the flanged one is 93101-28157. Im hoping they are in a size where I can buy something that will suit from a seal supplier. But I would really love to have the correct one for it.
