There are specs for all of these things related to cylinder clearances and crank specs, unfortunately most of these are specs that machine shops have and use daily. It may be worth while to check with your local crank grinders and machine shops for assistance with these. Michigan Cat, Cummins Bridgeway, and W.W. Williams Detroit use us all the time to check heads,blocks,cranks,turbochargers and injection systems. In the long run it's cheaper for them to do this than to chance the rejected claims due to being wrong. We have a guy we use and have used for many years to install repair sleeves in dry blocks. Saves a ton of money and he usually will come to your location to do the job. It may be something to check out if warranty numbers are way up. It's a good permanent fix and will save your shop some serious claim numbers not to mention save on customer pay jobs.
