I may be wrong, but I always thought the conical washer was a spring that had to be compressed a little to get the circlip on. I always used a press
I also believe that is the case. But IIRC it only needs to flex a smidge. So i sanded the washer and the clip down after a good cleaning. I had a few strike marks on the clip that were probably restricting the seating process.
Hammer and punch were the ticket. I punched down and in. Never heard a click, but it sure looks and feels like it is IN!
