Model B Flywheels - Early vs Later Counterweighted
Is there a difference between the Flywheel of an Early Model B non-counter weighted Crankshaft and the Later Model B with the Counter Weight Crankshaft?
I have one early engine and two later ones but only two flywheels that look like the lightened Model B style flywheel. Darryl in Fairbanks |

As far as I know all B's had the same wheel. The crank doesn't know, or care, what is bolted to it.

I agree that the crankshaft doesn't care and it will fit. It will make a noticable improvement in throttle response and acceleration on an ootherwise stock model A engine. I'm running one on our roadster and love it. It does look different than the model A flywheel after a second glance.

Re: Model B Flywheels - Early vs Later Counterweighted
Thanks for the responses, my later B engine came from a '32 BB which was complete, but the early B engine came with a Model A Pick-up and I have no way of knowing if it is the correct flywheel. I have never actually weighed any of the B flywheels.
For some reason I was under the impression the the Model B flywheels were reduced in weight by a similar amount to what was added to the Crankshaft by counterbalancing. Darryl in Fairbanks Last edited by darrylkmc; 11-12-2012 at 02:28 PM. |
