Thread: Crank pulley Measurements, Help

If you want, post the diameter and the distance along the pulley between the marks and we can do the math for you. Take good measurements. Is this thing on the car, or off the car?

It is on the car now. I didnt really think about using a protractor, lol. I kinda looked over the fact that 15 degrees is an angle measure of the marks. What you are saying makes total sense now. I am done with cars for night but will measure it tommor or some time during week. Changing headgasket on my kids honda, so I am done for nite. but thanks for making me think about it in a different way.
