4.0L HO Jeep Engine Build

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).

Sometimes them redneck fixes are as good as any, LOL.... I see no reason for one to be that tight either. Don't know why they make stuff like that. Maybe mics read less in China?? Heating to 200 is safe as the balancer probably gets close to if not hotter than that when the engine is running. Don't think I'd go much more than that though just to be safe.

Sweet looking TB. Is it bigger than stock?
