Does anybody have any tricks for holding the quad ring in place while putting the cover back on? After changing the primary/tran oil for the first time today, I had a bear of a time getting it to stay in place. (I eventually held it in place with a few strips of cellophane tape that extend beyond the edge of the cover. After seating the cover I slipped the pieces of tape out. I *think* everything remained in place.) Thanks in advance!
