Cylinder Hone Grit

I am replacing the piston rings in my Allis Chalmers Model C tractor with standard Hastings rings. And I was hoping for some instructions included with the rings as far as what grit hone to use to remove the polish on the cylinder sleeves, but there were no instructions included with the piston rings. Does anybody know what grit hone I should use?....thanks.
 
I usually use a bottle hone with a 180 grit if your re-ringing the old cylinders then wash with a detergent and a scrub
brush .
 
Use 220 grit for cast iron rings, or use 280 for moly faced rings. I am not that smart. I just looked it up. There is a lot of inf out there. Stan
 
Hasting has a great website. I have spend hours on there reading. I also find if you start too coarse some of those deeper gouges remain after the finer stones are used . I would rather hone all the way with fine stones.
 
I'd worry more about how to get all of the grit out of the engine so it doesn't take out your crank and bearings, you need lots of hot sudsy water
 
We were instructed at Vo-Tech to clean with soapy hot water as was stated below. Clean it out several times until taking a lint free cloth (or as close to one as you can get) comes out clean, then you know you have it clean enough. I would then lube the cylinders with light oil so they don't rust up right away. Hot water will do that to cylinders.
 
I would have to look at the grit, but my dad always honed with lacquer thinner, it cut all the glaze.
 
By definition, "hones" are used to re-size cylinders or to arrive at a precision piston fit after a rebore.

Since you are NOT intending to resize the bore or arrive at a specific piston clearance, what you want is a "glaze breaker".
