[V8] AC clutch

[Ed Kellock]

The ac system seems to work great.  It cools as well as I would expect it
to, comparable to my 5spd and my 93.

What I'm wondering about is how the clutch works mechanically.  When I was
working on the p/s pump, While I had the serpentine belt off, I noticed
that when I spun the ac pulley by hand, it felt a bit gritty.  I dribbled
some 3-in-1 oil in between the pully and the inner wheel edge and it seems
to smooth it out.  What I'm wondering now is, did I gum the works up,
literally?  I just went and sprayed some WD40 and then brake cleaner
alternately in between starting and stopping the engine and it seems like
it may have freed things up a little.  But the compressor wheel will still
drag on the clutch a little when I first disengage the compressor.

I have found the clutch online at 2-3 places for $123 or less.  I wasn't
really looking for compressors but I did see one in the $425 neighborhood.
So unless I'm not looking at what I think I am, there is some economy in
doing just the clutch.

Unless I have to remove the compressor to do the clutch.  Then it's going
to a mechanic.

Thanks,
Ed
