I bought a Carver SD/A-490T that needed a tray belt replaced. Bought the belt and tried to slip the belt over the pulley with no success. Zero clearance between top of tray transport pulley and tray rail. Nothing on the Carver user forum, just a lot of questions that never get responses on belt replacement technique. If anybody knows how this can be done I'd appreciate hearing from you before I resort to removing the entire transport just to get the stupid belt on.
