Hello,

I no longer have my factory cranshaft pulley. Does anyone know the diameter of the stock unit?
Thanks

 

~4.54" measuring the outside edge of the second pulley (pulley closest to your radiator) figure the inside ridge of the pulley (where the ridges of the serp. belt makes contact) will be a tad bit smaller.

 

Awseome! Thanks for the info. Is the outer pulley that you measured the one that drives the power steering pump?

 

yes the outer pulley (front, closest to radiator) drives the power steering. From what I can see, the two pulleys looks to be the same diameter. I don't have a micrometer with long enough fingers to measure the center distance for the inner pulley, but eyeballing it, it looks the same.

 

here is a pic, the measurement was taken across the center of the pulley, it might not look like it in the picture but it is.

 

Thank you. I appreciate the help!
