I pulled my 110F engine and have the crankshaft free, but can't figure out the trick to removing it from the case. The manual says to snug up the counterweight to one end and drop it out the other. I can't get the counterweight past the connecting rod bolts. Do I need to pull those out? Can it be done without pulling the pistons out? All I need to do is replace the crankshaft and related bearings and I'm stuck.
