I am restoring a Farmall MD and am finally starting the reassembly process. The sleeves I took out of the engine stuck out about .040" above the block which according to the manual is correct (one even stuck up .050". The new sleeves I bought from Case IH only stick up a few thousands of an inch above the top of the block. I just finished restoring a Super C and the sleeves stuck up too far and the head gasket leaked.
Does anyone know why the sleeves are supposed to stick up above the block. Is it to seal the high pressure of the cylinders? Engines without sleeves have a smooth transition at the top of the cylinders. I don't see how the head gasket can compensate for .040" step at the cylinder. It seems like all the manuals I have for Farmall tractors have a different number from near nothing on the M gas to .040" on the MD. However, will these sleeves that don't stick up above the block cause me problems on the MD. I would appreciate any information. Roger
