so i'm planning on replacing my a/c clutch assembly soon as i'm getting a loud wine from it while running. figure the bearing is going bad. i was able to order the whole assembly online for under $100. my question is, is there a specific air gap i have to set when i install the new one? most of what i've been finding says measure the gap before removing the old one.

also, any tips for removing the old and installing the new one?

 

.25-.30 is what they spec.

 

thanks. couldn't seem to find an actual measurement anywhere
