Default a/c compressor clutch going??

ok so with the car running (A/C off) i hear this sound of metal spinning at my A/C compressor kind of like when u take a wisk and spin it in an empty metal bowl. then when i turn A/C on it goes away. there was someone who already posted same problem back in november but didnt answer my question..

is there anything i could do without buy a whole new compressor (thats almost $300 ), such as replacing pully or something part of the compressor?

thanks

It is possible to replace the clutch only. And we recently had CorvetteCrazy post something about gapping the clutch plates and how that causes very similar noises.

However in it'* position ...it is difficult to get to at best.

Compressors aren't cheap (and HEEERRREEE'* Captain Obvious!) and if you have the time to pull the compressor and gap the clutch plates, it'* not a bad way to go.

Default plates

If the plates are dragging chances are the bearing is going out.
Best bet is to get a compressor from the yard.
I tried removing the clutch and you need a special clutch puller, then you must remove the snap ring, then put a secondary puller on the pulley.

That'* not always the case. And you don't have to remove the clutch nor even the compressor to do this adjustment, though removing the compressor might make it easier to get at.

See this link that was in the thread I linked above:

I'm not a real big fan of yard A/C compressors, 'cause they have to remove all the refrigerant before allowing the public to wrench on them and that opens the system to the elements. Just my preference.
