Flywheel
I remembering reading something awhile back about installing a model A flywheel on a model B crankshaft. It seems the A crankshaft has a radius on the outer edge where it fits into the flywheel where the B does not. I was told the A flywheel has a radius where the crankshaft fits to accommodate . With this in mind I believe you have to machine the radius out of the A flywheel or the model B crankshaft will ride up on the radius. Can anyone tell me what they have seen when this happens.

Re: Flywheel
I've never heard that about the radius. The A flywheel will not fit the B flywheel
housing and pan. See Vince's site. http://www.fordgarage.com/pages/flywheels.htm Bob |

Re: Flywheel
You have to modify the B pan then you can use the A housing and Flywheel.

Re: Flywheel
I would just instruct the machine shop to fit everything properly if there were any differences.

Re: Flywheel
I am trying to confirm that if you install a A flywheel on a B crankshaft that you have to do some machining. Next question I have is if there is a interference what happens if it's not caught before running the car. I suspect there will be run out because the flywheel cannot fit properly causing a vibration. Has anyone experienced this.

When I saw your post yesterday, again, I checked the crankshaft mounting surface on 8 Model A flywheels and one Model B flywheel and confirmed they all have a recess cut at the outer edge of the mounting area. There may be a radius down in the recess that I can not detect but it is/would be recessed below the flange mounting surface. See the photos of the B & A flywheels below. I checked 4 counterweighted Model B and 8 Model A crankshaft flywheel flanges and they all had chamfered edges. See photos below. I lightly face the flywheel flanges of the crankshafts when they are reground so it slightly changes the amount of chamfer. Yesterday, I specifically looked for original un-faced crankshaft flanges to determine the amount of chamfer and found the amount of chamfer varied. So in conclusion, after checking twice, I think what we both read back then was "bunk". Good Day! Last edited by Dave in MN; 03-12-2018 at 01:52 PM. |

Re: Flywheel
If you are correct that is good news. Thanks. Daren
