Ring cut see each ring bores are pretty common in the industrial transmissions we rebuild, so we sleeve plenty of cases.

We make our own sleeves, sweat fit them into the cases after boring them for the sleeve. Finish hone for final size and finish.

Since there's spinning shafts in these sleeves we have to make sure they get installed on center and straight. You're tolerances can be a little more forgiving for just the pistons.
