Now that I got my stuck crank hub off I found that it Microwelded itself to the crank snout. That raises the question of how to prevent it from happening again. Last time I took it off it was fine. Switched to a Bryant crank from a forged and added a crank support. After that it was Microwelded. No other changes to the engine. Is this common with billet cranks? Could the crank support have something to do with it? Thoughts?
