Ah so the shelves are tight as if trying to engage? So....it probably needs a complete service!! Thanks! I still think its odd that parts that "move " so much get no lubrication? I get the no oily belt thing but my weights have another of surface rust. I took a green 3m to all that the best I could but I should remove it and inspect it all then service it. I'll Google it again lol!! Thanks man that makes more sense now. If it where worse, you'd be trying to turn the track right. Like starting it in gear so to speak? OK a good idea for sure!!!
