A/C clutch ?

Yesterday I went out and turned on the ignition without starting the truck and put the a/c on and then turn the clutch by hand, it engaged. Worked for awhile. Today a different story, would not engage at all. Are these easy to change out? I believe that is the problem.
Thanks all.

Fairly easy to change out. Depending upon the type and amount of wear, you may only need to reduce the air gap between the clutch and pulley which may be as easy as simply removing the clutch, removing the shim, and reinstalling. Worse case scenario is replacing the clutch and pulley together.

Here is a link for you...

Went out to check the gap and it's a whopping 1/16".

Took it apart and removed a shim washer that measured .045". Working again now...

The 0.045 is still nearly twice the typical target, and is over 3x the gap you can actually get away with. I would go ahead and purchase a new clutch. If your pulley surface was scarred very badly at all, I would also go ahead and replace the pulley with the clutch. I found my best prices from Tousley Ford when I purchased my set a couple months ago.

Ford's suggested list pricing totals $175 for both parts, but Tousley's online price is only $106 plus S&H. When I bought them, the total order was $118, including shipping to my place in Birmingham, AL. Since you're closer to them, your shipping would be a few dolllars less.

The parts I'm referring to on the diagram in the above link are item numbers 6 and 7, and the pulley comes complete with a new bearing, but you need to reuse the center bolts from your truck to put everything back together.

I too, though, am running with cool air again by just having removed the shim, but will still go ahead and replace both the clutch and the pulley very shortly and save the ones on the truck as emergency spares for either my Excursion or my son's F250.

He didn't say what the final gap was on his clutch, he said he removed a washer (shim) that was .045 thick. The target is .015 to .02 (I believe) and was not mentioned in his post.

So, DISLFVR, what is the gap measurement after removing the shim? If it is too large, you may need to replace the clutch. If not beyond specs, you should be good to go.
