At the Turlock Swap Meet on January 25 and 26, we will sell "New Engine" parts at "Event" pricing.
We have a preproduction "New Flywheel Housing" for evaluation and approval. Please stop by our space in the building with the snack bar to buy parts, and see and discuss our new flywheel housing, which looks original but is 12 times stronger.
Original Model A flywheel housings crack at the 2 lower attachment bolts because all front axle loads transmitted through the wishbone become bending loads on the flywheel housing.
Ford knew about the problem and during the 4 years that Model A Fords were manufactured, the flywheel housing design was changed 8 times. The last change on October 26, 1931, added external ribs to areas that are lightly loaded and don't crack.
Our new flywheel housing is an improvement on the 7th revision, it is about 12x stronger where they crack and come with an O-ring groove and O-ring to seal the back of the camshaft.
Our new flywheel housing has several internal changes that are hidden. The thickness at the attachment bolts has been increased from .500 inch to .875 inch which is 3 times stronger, the width of the material at the lower attachment bolts is twice as wide, and the new material is about 3 times stronger than grey iron. If you do the arithmetic, the strength at the 2 lower attachment bolts is 3 x 2 x 3 = 18 times stronger than the original. Being conservative, I'm comfortable saying that the new flywheel is 12 times stronger than the original.
For blue point judging, the exterior appearance of our new flywheel housing is correct for all production before November 1931.
