LAYSHAFT ALL AMC NORTON BOXES

UK MADE.  SUITABLE FOR ALL FOUR SPEED NORTON AND AMC GEARBOXES WITH KICKSTART.  ie FITS COMMANDO, ALL SINGLES, ALL HEAVY TWINS AND PRE UNIT AJS AND MATCHLESS (USING THE AMC GEARBOX).  IF YOU HAVE A GEARBOX WITHOUT KICKSTART ie MANX, THEN YOU SHOULD USE 040025M.  THESE SHAFTS ARE MADE IN THE UK USING TOP QUALITY STEEL AND ADDITIONALLY THEY DO NOT HAVE THE DEEP UNDERCUT GROOVE OFTEN SEEN ON THE GROUND DIAMETER WHERE IT BUTTS UP TO THE SPLINE.  THIS GROOVE IS THERE ONLY TO ASSIST WITH THE GRINDING OPERATION, IT ELIMINATES THE FREQUENCY OF WHEEL DRESSING NECESSARY WHEN GRINDING TO A SHOULDER.  FINE ON EARLY GEARBOXES BUT WHEN THE ENGINES GOT LARGER AND TORQUE INCREASED SHAFTS COULD SNAP EVEN ON STANDARD 850 ROAD BIKES.  IN OVER 20 YEARS OF SUPPLYING THESE SHAFTS WE HAVE NEVER HAD ONE SNAP.

OVERALL LENGTH: 5.850" (150MM)

SEE 067710 FOR A HEAVY DUTY ROLLER BEARING FOR THE INNER END AND 040146 FOR THE SHOULDERED BUSH THAT FITS INSIDE THE KICKSTART SHAFT.

GEARBOXES USING A BEARING TO SUPPORT THE OUTER END OF THE SHAFT, ie MANX, SHOULD USE SHAFT NUMBER 040025M
