Dick the entire problem is a good one for the Farmall list.  Not just my
musings on how to fix the bushing.  Some of those guys have certainly been
through that engine and mighe well be able to tell you what is wrong and how
to fix it.  If you are not on that list maybe someone could forward it for
you.
