Looking for an early 400 flywheel good condition, Here's a shot also an early 400 crank, that is drilled for the pilot bearing, I have a decent auto crank, and can have it drilled, but this seems to be a hit or miss proposition, the last one I had drilled the bearing is to tight, I know this should be posted on another post but what is the correct diameter to drill for the pilot bearing and what is the depth
Thanks Take care Dave
