Lines: 18 When I had my 1541 serviced, I had installed a spring replacement stop. The service man, who was quite outspoken but also quite competent, said that the spring was not needed and proceeded to show me that the pulley for the head positioning band is in a block which should slide on the head rails. He said that that this block is almost invariably frozen on the rails. As part of the service he lubricated the pulley block so it moved freely on the rails and he reinstalled the solid head stop. The drive just made a purring sound when it hit the stop. All the shock is taken up by the pulley. I am not sure what sort of lubricant you would want to use but it should be something that can be used sparingly and that will stay put. This seems like a much better solution to head noise than mucking around with the track 0 stop. I also have a suspicion that many so called alignment problems with the 1541 are actually related to a lack of lubrication on the head rails.
