Cylinder #4 Running Hot

Cylinder and exhaust port #4 run hotter than the other cylinders and exhaust ports. I believe this is due to reduced cooling water flow in this area.

The original Model A cylinder block castings...

Re: When going for SCAT crank should you lighten flywheel? If so, how much?

This reply is in regards to earlier comments regarding broken crankshafts, destroyed timing gears and other problems.

If a crankshaft is hung with a string and tapped with a hammer, it will ring...

Re: High compression engine life.

Cast iron shrinkage from molten to solid is roughly 1/8 inch per foot, so what you are seeing is a new cast iron part that used an original part for the pattern.

Re: rear main leak

Benson,

I just re-read your post, and see that you don't have the instructions. They are copied below without the figure.

Re: rear main leak

Benson,

It's better to use pressurized oil instead of air because oil is very visible.

You can go up to 50 psi if using a one-piece seal with the insert from Dan Price (dan4banger.com). The...

Re: rear main leak

After you remove the oil pan, don't do anything until you pressurize the rear main drain tube with oil and look for leaks.

This is the last step in the instructions before the oil pan is installed.

Adding it to the flywheel does nothing to mitigate crankshaft torsional deflections!

Re: eBay Winfield

Jim,

You should have used a Winfield SR-CC-D which has an accelerator pump to eliminate the flat spot after idle.
Winfield S carburetors did not have the accelerator pump.
The pump was at the...

My copy of A-6015 has EI 12403 3/28/1929 incorporated with no Brinell hardness mentioned.

Re: babbit tolerance? .000?

There are no Brinell hardness requirements on the drawings.

I agree that most dimensions are specified without telling the machinist how to do it. Some dimensions tell the machinist to...

Re: babbit tolerance? .000?

That would be like saying the engine cylinder cases (blocks) were bored to 3.8735" in size. While that is accurate statement, that was not the finished bore size after honing.

Per Ford drawing...
