So, its 8:00pm, and I am needing to take my alternator rotor off. The shop manual says to use a Metric 20 bolt, and thread it through the center of the rotor, and it will go through and push on what is behind the rotor. The problem is, I do not have a Metric 20 bolt, and none of the big box stores that are open have anything metric that large. I could probably go to fastenal in the morning and get one, but I was really wanting to get the motor taken apart tonight. I tried a claw puller that I have, but it does not fit well. Are there any other ways of taking this off that I could do tonight?
