I found the sweet spot for the crank with the counter-weight part of it out of the way and the bearing cap came off. The crank surface is smooth as a whistle. Can't feel anything at all.

The bearing surface has some grooves. My fingernail catches in a couple of them. It makes sense they would make the crank out of harder metal than the bearing.

What's next? New bearings since it's open?

One other question. Will it ever stop dripping oil?
