Nope, no flames. The TC's XPAG engine does have a pilot bushing, and it's
often overlooked during rebuilds because it is often hard to get the old
one out. However, since Dave was replacing a broken crank, I would
imagine he replaced the bushing too (since new cranks usually have the
bushing pre-installed). Um, Dave, you _did_ check that, didn't you?
Anyway, a worn pilot bushing causes noticeable vibration, but not the
violent shaking Dave described. Unless, of course, that new crank didn't
come with a bushing and Dave forgot to install one. Um, Dave???? :-)
