Before I attempt a fix for this alignment problem ,I wonder if any of us bricksters had this problem and what the fix was. When looking down the pulleys I can definitly see the misalignment. Also their is quite a squeeky noise due to the misalignment ( the noise goes away temporarily when the belt is sprayed with belt dressing). I could not tell on initial inspection if bushings are involved. The only thing I can think of is that the tensioning mechanism over the years has become somewhat bent thus causing the problem. Any thoughts?..regards Paul
