I am working my way thru rebuilding the G188D engine from a 1971 Case 580CK. It has the very common spun #4 rod bearing problem. The issue of the day for me is removing the dowel rings that align the head to the block. They are 'stuck' into the block pretty darn well. It would be easier to clean the head mounting surface on the block and inspect for flat and for flange projection if these rings were removed.
Have any of you who have built this (or other) engines found any good tricks for getting these out? When they were installed were they a heavy press fit or a slide fit that has grown together?
If I have to work around them I can, but I think that is less ideal.
Thoughts?
