Yes, I have dis- and re-assembled the upper tension according to the user's manual. Looking at the SewUSA link, seems to be the same thing. And, even though the instructions say it's not necessary, I did remove the stud and clean that area. All in all the machine was in very clean condition which was one of the things I checked as well as possible before I bid on it. Actually had a screwdriver with me and took off the top and face plate to look there. Was almost expecting to get my wrist slapped by the auction house as we had never been there before LOL
