I had the same problem.
Several experts told me not to waste money on the clutch or pulley.
They said when the compressor seizes it tears up the bearings in the AC clutch pulley. The bearings in my pulley are shot and when I rotate the pulley, it sounds like a grinding noise.
Since you are going to have to get a new AC compressor which comes with a clutch, don't waste money messing with the AC compressor pulley/clutch/bearing assembly.
I don't know how they did it, but when I bought my F 150 it has a serpentine belt that runs everything but bypasses the AC compressor which is seized. I guess there is a shorter belt for F 150's without an AC.
An AC expert told me when I take out the orifice, I can see if the system is terribly contaminated. He said the accumulator and orifice should have caught most of the crud from the failed compressor depending of how fast the AC compressor failed. Either way he told me to flush the Condenser, the hoses, replace the accumulator, and replace the orifice along with the compressor.
Ordered the parts online and everything cost me $ 255.00 with shipping (new).
I am going to keep the old belt when I fix the AC so if that happens again I can get back on the road with a 3/8" socket to slack the belt and put the shorter one on. I will carry the spare parts behind the seat.
Probably not a bad idea for anyone with AC to have that shorter belt and a cheap socket wrench so you don't get left on the road.
