Cleaning parts to put the '15 touring rear back together and found this copper color under the black. I assume its a primer????
Perhaps brazing? Crack repair? The picture is too small for any detail. Scratch it with a file and see if it shines.
Found the same thins on the rear radius rods
It's not uncommon to find brazed areas on the Model T. Both as repairs and from the factory. The crankcase pan alone has about pound of brazing when it leaves the factory. It's used to seal the rivet holes and oil drain cup.
If you run a file over it and it shines, it brass (brazing).
Brazing. The Model T is full of it from the production process, especially the crank case
Naked 1915 pan.
My 26 pan i am cleaning up has alot of brazing on it also. Tim
If you look at an old book, I think it was called Ford Methods and Ford Shops?? There is a part that shows these parts being brazed. Seems they are sealing the rivets holes. Mike
That naked pan might have been on your 15 but it's not correct, it's a later one, wide noise and lipped edge.
Frank, you're right. I should have paid attention. That one came off a 1922 engine.
