Crank Hole Finish Size For Pilot Bushing

one word of warning about drilling it out though is plan on a workout and a half. Its a time consuming job that will make you feel like you worked out all day.

Don't be distracted at all when drilling. One of the times I did it, I got it cutting and I let go of the drill with one hand because I thought it was going smooth and it was cutting smooth but then when it hit a burr I only had one hand on it and it twisted the drill around and broke my wrist. So when your drilling its a job that you cant be distracted and you have to be patient.......its no easy task.
