Dash AC compressor clutch

My AC compressor is making some serious noise when the clutch kicks in (not all the time) that's why I think it's the clutch.
Is this the number to reference for a new clutch?

Thanks

It could be the compressor. Try turning the compressor by hand.

Dash ac works, and cools so do I still need to turn the compressor by hand?

See if there is possibly any oil on the clutch and could the noise be from the belt?

I would think if it was the belt ( which is new) that it would make the noise all the time and that the noise would be from a loose belt. Is that correct or am I wrong.

Belt noise will be different than clutch or bearing noise Frank.. The unit may still cool while making noise but it will still fail as in seize up and cause a potential added problem you will want to avoid.

Now the question is........was the noise there BEFORE the new belt?

No noise before new belt.
After I replaced belt there was no noise while I looked at the belt with engine running, but did not have AC on at that time

With the A/C on there is a pulsing resistance from the compressor. Check for slap with the A/C on, the belt might just need tightening.

If the problem started after you changed something, that's where I would start. Granted, it may not be the belt but it is curious.

First I would spray some belt dressing on the belt after properly tightening it, and if that didn't help I'd try a completely different belt.

I I'll try to tighten the belt tomorrow. If I go to town I'll get another belt and replace it. I'll report my findings.
Thanks everyone for the input

Is that 1" - 1.5 " pushing in on the belt between the compressor and Fly wheel on the engine
