I don`t know when the adjustable pins were introduced but 27/28 Flyer clutches certainly had non adjustable pins, the problems start when the plates wear and the clearance dissappears at this point owners would grind down the pins without being very accurate about keeping to the same length and at a later date when plates get renewed owners find they cannot get full lift to free the clutch. While adjustable pins can answer most of the problems sometimes previous owners have shortened the pins on a badly worn clutch, and also standard pins seem too short for a present day refurbished clutch, I always advise owners to sand new fibre plates by .020″ if they are fitting one of my alloy pressure plates. I have been asked about supplying new adjustable pins recently, if no one else has these available I will consider making some please let me know if there is any interest.
