Compressor clutch problem
To update this is what I did. My Mom owned the truck when I put a conversion kit on it and found out the compressor had a hairline crack. A couple of years(01/03) later I bought the truck. A few weeks ago I bought a compressor out of the junkyard and swapped them. I filled the system with a kit of 3 cans (oil,stop leak and refigerant in one can) guage read 44 when done.
The A/C worked great for about 15 minutes down the road then the clutch would stop spinning. If I would tap on the front of the clutch it would start spinning for 5 minutes. I thought maybe there was too much in the system so I let some out(just a guess newbie here). Well now it was at 25 lowside and the clutch was clicking on and off. I put the guage on it and it was going from 44 to 24 back and forth. ok from what I have read this is normal for a low charged system.
Now I got around to putting a can of 134 only in today and it's at about 32. The A/C worked fine for a while(20 minutes down the highway) then the clutch stopped spinning again. I bought a test light and there is current to the plug when the clutch stops spinning and if I tap on the front of the clutch it starts spinning. I think my system is working alright and I have a problem with the clutch.
Can this clutch be fixed? someone said something about shims. Where are they? I took out the bolt in the front and pulled out the outer round thing. All I could see is a spline and a C clip. If I take out that C clip will the clutch and pully come off and is there something I could fix in there? Autozone want's $88 bucks for a new clutch. What should I do.

Compressor clutch problem
I drove to the market today and the A/C was fine both way's. When I got home I took off the cycling switch and turned the screw back (counter clockwise) 1/8 of a turn. This brings the setting down to 22 from what I've read.
I then measured the gap with my old feeler gauge(Time for a new one) the gap is greater than .032. I looked in the hole and didn't see any shims. Sprayed some WD40 and still nothing. There is some dirt or rust in there so they might be in there.
I noticed some rust on the back of the clutch plate so I took some sandpaper to it and then sprayed it with WD40 and hosed it off. I also sandpapered the front of the pulley. Now before when I would pull off the plug and put it back on the clutch plate wouldn't engage right away. Now it engages right away. Does this make any sense? I don't know how the clutch works, but now it works better.
I did some reading and it is said that on the Bronco and F-series trucks they changed the fan clutch and a condenser with fins on the side and something else(I can't remember).
I did notice that I have an oil cooler in the upper corner in front of the condenser. Will this effect anything?

Well I did some research and found this site:

I didn't know the clutch worked on a magnet. I guess with the rust and the wide air gap it wasn't connecting totaly. I'll know tomorrow. I don't want to count my chickens yet.

Compressor clutch problem
Well the clutch still didn't work right,so I looked for shims. I thought the shims were in the pulley hole. Nope just a piece of felt. Then I looked in the clutch hole and there was a small washer. I took out the washer and put the clutch back on and it fit against the pulley. I then found a washer 1/2 the thickness of the one that was in there and put it in then measured the air gap and it was now .022. I drove the truck for an hour or so and the A/C worked great.
