First thing is you need to clamp them down before measuring. Then you need them to be close to the same protrusion within a couple thousandths as I remember.
Not sure CAT ever published a spec on the old engines. Probably could use the specs for a D342 or something modern.
You have a problem at .015 if that's what you end up with after clamping the liners down. Search the site for "Liner Protrusion". There's several threads. Here's one for a D4400.

The machine shop that decked the block claims they took same amount
from counterbore as taken from deck. So maybe i will clamp them down
first, then measure height. I really dont think the .032 copper gasket will
compress more .001. Maybe liner flange is thicker than original,or these
copper gaskets are thicker than original. These are all OEM cat parts.
But today who knows about quality control.
Thanks for input Joe Westfall
Was there no paperwork with the new sleeves? There should have been and if there isn't then contact the manufacturer of the new liners and see what they have to say.

I have new liners here ready for my D2 4U known as "The Boat Anchor", but I wanted to ask about checking liner protrusion because I wasn't sure about having the nice new upper copper gaskets crushed while measuring the variance from cylinder to cylinder, is that normal practice, to pull down the new liners onto the new counter bore copper gaskets to check protrusion, then pull it all apart to fit lower rubber "O" rings with appropriate lube and re install it all if protrusion is OK? As I understand it, liner protrusion can be anywhere from 1-5 thou, but each liner must be within 1 thou of each other, is that correct?
thanks
Mike
yes, that is how you do it, check protrusion and leave the o-rings out. You will not be clamping the liners in place so tight that they will crush the copper gaskets but enough to have them fully seated. If I recall right the .001 is desirable on variance.

I like to use these specs.......
I like to use these specs.......
would these specs. work on a d8800 engine also? thanks
