I have a 1948 8N that had a bucket loader on it, it had a front hydro pump, the loader and pump have been removed. There is a spacer or shield on lower pulley between pulley and front frame. If I break the belt I don't know how I would change it as there is no way to get a belt onto lower pulley. Is there a way to remove that shield or is that part of the lower pulley. Thanks for any help.
