Fishy, this was a redneck fix but it worked! Heat was an option but what about the elastomer? I see no reason for a interference fit that tight on just a HB with a KEY for crying out loud. I wonder if they make them tight to compensate for worn crank snouts or under the assumption that a machinist will install them? I just don't know...
When I measured it I was blown away. I wanted to write Dorman right there on the spot but I figured that my time was much better spent making a "wrong" "right" right now, so that's what I did. No wobble or undue runout either (compared to stock).
