I just learned that if you turn your crank, you have to get the corresponding bearing to adjust for the material taken off of the crank. Useful info as I’m planning on using the crank from this block. Crisis averted. Lol.
Indeed you do. Both my cranks are ground 10 under both mains and rods; bearings need to reflect that.
So you're using a cast crank, then? Do you know if it's the standard cast or the shot-peened version?
