That answer is going to save me quite a lot of money. I was thinking I would have to pay a Cat tech to remove belly pan, oil pan, rod bearing, piston, and sleeve to recut the block cylinder and shim to specs and install sleeve. Now I am waiting for Cat Florin to get my new head completed and put it back together. I had a major compression leak into radiator and was hoping for cracked injection sleeve. I did have a bad one on number 2 cylinder but the real cause was 2 major cracks that permeated out from injector threaded hole up into the interior of the block. The radiator was replaced by the previous owner with wrong radiator and it was unrepairable. I asked Caterpillar Peoria who they use for radiator service and was told REX Radiator of Peoria,IL. Rex did a outstanding job. They were not cheap. I spent $5000 but would do it again. Junk radiators were selling on the net for $900.
Thank you again to Rome K/G

Specs are hard to come by For the D7 and the service manual isn't much help other than stating the liner should protrude slightly.
In general we have been using the specs for the 3306 engine which applies to other engines as well. Be sure to clamp the liners down when checking and use the information attached as it applies to the D7
