Going after the bearing. Will I need any unusual/custom tools to unlock the box? The mass of information regarding the gearbox on the forum has left me somewhat confounded being new to the Norton. Don't get me started on the oil threads, good lord. Its easy to get lost. Anyone with experience (seems most everyone) have a clear procedure for attempting gearbox work in situ? Been through the Old Britts tech pages, out of my depth there. Thanks for the help.
