I now have .036", Stainless Steel cylinder liner shims, for Cummins ISX. 2014 and newer, with factory brass shims. No counterbore machining needed, in most cases. Gets liners up to .014" protrusion. Call me 717-368-8532.

I am now fully convinced, that Paccar has a problem, with soft counterbores on front and rear cylinders.. I am finding many,many, times, that the #1 and/or #6 counterbores are badly fretted, even though the liner protrusion, is well within spec.(.006"-.0065"). I am told, that when manufacturing compact graphite iron, it requires a very complicated process of heating and cooling. It appears that the front and rear cylinders are not heat treated, correctly. I even had one re-fail, after a very short time, after machining the counterbores to max protrusion. I am now cutting any, badly fretted, front or rear cylinders, for a stainless steel shim. Being, a dissimilar metal, it is less likely to fret, even if it does move, in the block. The one that had re-failed, and now, has a stainless steel shim, has now been working well, for a long time.
