ac clutch replacement issues

I have a 1996 F150 with the 4.9.

Replaced the ac clutch. Shimmed to the .014-.033 specs. When I turn on the ac, the clutch spins on the front of the pulley surface. (Slipping, I assume). I am wondering if I should reduce the gap, or enlarge. I am assuming reduce. Current spacing is .024.

Thoughts?

Thank You!

Can you turn the clutch, and therefore the compressor, by hand? Are you sure it's not the magnetic coil that is at fault?

Replaced the pulley, clutch, bearing, and coil as a set. I can turn the compressor by hand.

What was the old one doing.. same thing? If you have battery voltage at the comp, backprobing, with it connected then you either have a bad clutch or more likely, the compressor is too hard to turn.

It appears the compressor is going out. Disconnected the field coil so I don't accidently turn it on. Now I'll be looking for a new compressor and all that other stuff to rebuild the system.

Thanks for your help!
