What's the best grit of a ball hone to just to remove the glase of the wall to re ring

240 or 320 for standard ring only cast

240 on a cast ring with stock cast iron block.
Use 50/50 WD40 and ATF for a honing fluid.

Thanks I thought it was but not shure

I don’t like nor recommend ball hones for what I think are good technical reasons. That said the hone used depends on the rings used. I think they are marginally OK if you have straight walls. If this engine has wall taper, out of round or wavy walls the ball hone is incapable of correcting these conditions. Being flexible in all dimensions they fake you you out leaving a great looking finish but all they do is put a shine on whatever surface is there they don’t correct defects, so you need to appreciate that going in.

Chrome and plain cast iron use a coarse hone as in 240.

Moly prefers a finer finish from a less coarse hone as in 320.

Some guys prefer what’s called a plateau finish where you start with a coarse hone and finish with a finer grit.

This one had a very few miles on it like 20,000 on it and the crankshaft trust went out of it so it's completely tore apart and getting rebuilt with new rings and different crankshaft

When you're glaze breaking for a re-ring , you're really not trying to " straighten out" the cylinder walls ,I M O . For an at home re--ring , the dingle balls seem to do just fine . If you're building high performance race motors, there are better ways .

Yes just a re-ring job only

I just did a re-ring on my 97K mile 5.0. Cast rings and I used a 240 grit ball hone. Came out nice!

I just ordered one on line

Find someone with a dial bore gauge , check the bores , if its too far out , rings won't seal . !anything over .003-.004 is too much , dependent on proposed use .

 

[1953bigblock]

It will be fine with less then 20,000 miles on it

Cost too much to check ?
