I know the tapers are different, but will a 40 wheel clear the advance and throttle arms on a stock model A column. Has anyone done this recently ? Thanks Tk Posted using the Full Custom H.A.M.B. App!
I believe the taper is the same in degrees, it's the diameter that is different. The 40 wheel, if I remember correctly, won't go on the A shaft far enough to get the nut on. Posted using the Full Custom H.A.M.B. App!
I initially played around with that exact setup - 40 standard wheel on an A column. After I turned the shaft down 0.04" I was able to get the wheel on...I'm pretty sure it cleared the levers just fine. If it doesn't, you could always trim the bottom of the mast a little to give you some extra room - but you might need to tweak the advance rod a little. Another option that would give you some more room is to use a 1928-Feb 1930 column mast - they're 1" shorter (37 1/2" overall length) than the later ones (like yours).
FWIW, Model A taper dimensions (1930-31): Minor diameter - 0.72" Major diameter - 0.79" Length - 0.90" 32-48 (passenger) taper dimensions: Minor diameter - 0.68" Major diameter - 0.75" Length - 0.90"
