I am putting together a 25 lb little giant trip hammer new style I believe and the tension spider is coming off the shaft. It looks like there are threads where the shaft attaches to the spider. I am wander if I am missing a part that attaches the spider to the shaft and how the spider attaches to the shaft. I was thinking about hitting the spider with a rubber hammer to move it further on the shaft, but I don't want to break anything
