1941 Farmall A engine

Thank you

In any event eplacing it now would not involve replacing the block. It's centered up in the enrar end of the crank.

I agree with the others that the epoxy patch for the old crack (lemme guess, it's behind the carburetor) will hold. The A, unless it's been modified, is a non-pressurized cooling system, so there's no fluid pressure to speak of on that repair, though there will be some lateral stresses on the epoxy bond from the iron expanding and contracting at a different rate than the patch. That said, many of those repairs were made and have been holding water and anti-freeze for years.

I vote for keeping your block and getting that pilot bushing taken care of.

Why on earth would any decent mechanic not replace the pilot bearing when he replaces the clutch? Especially since he noticed that it was worn? I would not be happy about that clutch job, because it wasn't done right.

There are many, many Farmall A, AV, B, BN, C & Super C blocks out there working every day that have had freezing damage and been repaired. On many, you couldn't tell unless you grind off the paint and see the repair. You may even buy a used block and find out that it too has been repaired.

That original block has a serial number that matches the tractor serial number. No replacement block will have that. I would repair it, or have it repaired. It will outlast all of us and then some. And you will have Grandpa's complete tractor.
