I would be concerned that a connecting rod bearing is available  -.040 for this engine.       

That is exactly why I suggest he have the machine shop source the bearings.

I was thinking the same thing when I read the measurements but I checked Andy Bernbaums (oldmoparts.com) and they list up to 0.030 for mains and 0.040 for the rods.

I read into that they are available in general up to 0.040 for the rod ends.

I did Not do any further checking however.

Do you have a micrometer or set of calipers available to you? A quick check would answer your question. But I would have to agree with Don the machine shop would know best and should be able to order the correct ones at a reasonable price.

.040" is not what I would use either.... .030" max for me.

[John-T-53]

My motor's previous incarnation had .050" under rod journals. These very very tuff to find at the time, apparently.

well, that crank did not last long, but there were other issues that were the culprit... Bell mouthed honing job on the rods and improper radii at the sides of the journals. When the crank was magged after disassembly, it was found to be cracked in several places.

but yeah, have the machine shop get all the bearings...

Flathead engines don't use push rods. Push rods are used on overhead valve engines. They go between the cam tappets and the rocker arms to push the valves open. Connecting rods connect the crankshaft to the pistons.

Exactly...  This is why I scratched my head on the pushrod bearing reference.  I was questioning the meaning and wanted to know what exactly he meant by it.   The term "pushrod bearing" did not originate from me, just in case some  folks have misread something here....

I call 'em connecting rod, big end bearings. Of course at opposite end of the small end bearing. Aka piston pin bearing.

Due to occasional 18+ hour work days, I can totally relate to this.  Especially when your totally exhausted and can't find the right words!  LOL

Thanks for sharing.

I'm back! The engine's back from the machine shop and starting to reassemble! One thing I was able to get done easy, and was sweating it was the water distribution tube .  I bought a cool tool that attaches to a slide hammer 1/2 " shaft. And pulled it right out both pieces!

Sounds like you are doing it up right. Keep us posted on your progress

Looking good man!  

[51Meadowbrook]

Ok I'm having a senior moment trying to remember wher this goes ? I'm pretty sure it goes on either the front or rear seal on the outside of the  engine judging from the rust on it ! 

[51Meadowbrook]

I figured it out it's a clutch pan dust seal

[51Meadowbrook]

Starting to look like an engine !!

Flip that picture upside down and people might think you copied Don C! Is it just the angle or is that a really tall waterpump??

[Plymouthy Adams]

it is the lack of head and manifold and other parts not show that show this to look disproportional to size...an optical conclusion

I back off my original inclusion and will go with a exclusion on believing anything about the two above posters comments as my conclusion. There comments are delusional.
