Well, I have all the components apart on the '52 8N sidemount. The mains are .030 and the rods are .040 So when I take the crank to be checked/ground, am I going to be able to gets the mains up one for .040 and the rods up to .050 or .060?

Here's pics. The only bearing shell that had copper showing was the one pic on the right (rod bearing).








[b:82f54d8d1d]What does this rod/bar do inside the block? (there is two of them)[/b:82f54d8d1d]




On a good note, the crank pulley came right off with a little tapping. I sprayed it with PB Blaster several times over the last week and off it came!
 
Before they do any grinding, they better find out what is available. Maybe use it as is if you don't work it much.
 
Go back with the same size bearings. Not enough
wear to re-grind that crank in my opinion and I
doubt that any bigger bearings can be had.

They are worn pretty even. If it were a Farmall I would just go
with the same again. You don't have to have oil pressure sky
high to make it run just fine for the next 30 years. What kind of
work do you do with it? If you aren't farming with it every day it
will be good with new of the same size.
 

Mainly used for bush hogging and box blade and little bit of disking in the spring. In the summer, the oil pressure would start out pretty good (40psi) and steadily drop to nothing at idle and around 5-10psi at running speed (640). Also the compression was very low (about 65 lbs) in all cylinders. Just plain jane wore out. Figured it would be a good thing to do this winter and avoid a big bang and piston hanging out the side of the block...lol.
 

Here on YT, the mains go up to .04" and the rods go up to .040" (and then skip .050") and go to .060" available.
 

I'm going to drop it off at the machine shop tomorrow and let them check it with their fancy gadgets. They won't grind it unless it is necessary. I've taken stuff to them before and they will just polish it up, if that is what it needs. Pretty good guys working down there. If it needs a grind, that's ok as I would rather do all of this while it is apart. I'm getting too dang old and decrepit to be dragging tractor parts in and out of the barn...lol. Well not that old (58 ) but dang sure feel decrepit in the winter. :shock:
 

Could you tell me what that pipe does in the last photo (there is one on each side of the block) ? Maybe carries oil?
