using dry sleeves in a wet block?

I can't remember for sure, but I thought a stock oliver sleeve is a common mod for that. H sleeve is too thin.
 
(quoted from post at 13:38:03 12/20/13) Been doing the math on a spare farmall c135 motor from a 404 tractor
Engine builders how thick should a sleeve be in a wet sleeve engine? I can use stock farm all h sleeves in this motor but its a dry sleeve And may be too thin?


Circle track engines use .250 min wall T on the thrust side of the cylinder wall, .200 min anywhere else and that is with the higher nickel content iron. My experience in racing engines with less wall is that the motor just becomes a tickin time bomb and usually takes out a lot of expensive parts when the cylinder wall splits. Maybe tractor motors can get away with less, but with lower pin placement and long stroke it wouldn't seem likely.
 
Andy I had some that were .125 once. It was hard blocked in the bottom 1/3 of the block. I ran it a year and the took head of to change it. You could look in the cylinders and see the hard block line on the inner bore of the sleeve. I was getting cylinder flex above that point so i say .125 is to thin. I don't know what is safe I was told .125 was ok and this was on a 5 inch bore. Thad
 
.093 to .125 ductile iron.its not so much the thickness that gives people problems as it is inproper installaion .
