First let me say that I'm new here so please let me know if I'm posting in the wrong place or something. I have a 94 stx 583 with a blown crank seal, I order the new seal and the puller from Dennis Kirk. It showed on the website that it fits my sled. It showed up today and the threads on the puller are too small. I don't know what to do because all of the pullers from other places look identical. Looking for someone to help me in the right direction.
