FORK STANCHIONS CHROMED, MANX 20 3/8" ___(PR)

UK MADE
MAIN TUBE NOMINAL DIAMETER: 1.359 (34.5MM)
BOTTOM BUSH NOMINAL DIAMETER: 1.279 (32.47MM)
THREAD: 1 1/8" X 20 TPI

THERE WILL BE A SLIGHT VARIATION FOUND ON STANCHIONS OVER THE YEARS DUE TO FACTORY TOLERANCE AND THE LARGE VARIETY OF OUTSIDE CONTRACTORS/COMPANIES WHO HAVE MADE BATCHES OF THESE.  THE ABOVE DIMENSIONS ARE CORRECT FOR ALL STANCHIONS USED ON NORTONS WITH THE EXCEPTION OF THE JUBILEE.  THE THREAD FOR THE STANCHION TOP NUT CHANGED VERY SLIGHTLY FROM WHIT FORM TO U.N.E.F BUT THE PITCH AND DIAMETER REMAINED THE SAME AND NORMAL COMMERCIAL TOLERANCES ALLOWS INTERCHANGEABILITY.  THE BOTTOM BUSH IS RETAINED WITH A CIRCLIP ON ALL EXCEPT THE LONG ROADHOLDER, B2605.  THESE FORKS DO NOT HAVE TWO WAY DAMPING AND THE BOTTOM BUSH IS RETAINED BY A NUT WHICH DOUBLES AS AN OIL RESTRICTOR.  ALL NORTON STANCHIONS HAVE THE SAME TAPERED TOP.
