I was checking back on your post to see how you made out when I noticed something in your second picture; is that
exactly how the tool is set up when you encountered the resistance? Reason I ask is that I just notice the center bolt in your pic is protruding out quite a bit (the large silver thrust wash is not in contact with the tool’s cup face as it is in my photo and the one below). If that is the case, something is not set correctly and you should disassemble the tool and reset it so that the thrust washer is up against the tool when you start to tighten it; that may help with your issue…….
