HRL, Don't they make those tools for rolling out main bearings anymore? Mine are a shaft the size of the oil hole in the crank with a flat tee head at an angle to match the oil hole. They're made of aluminum. If they're no longer made, I'd better treat mine real well. I imagine I'll do an in-frame again before I die.
