Old Style AC compressor replacement parts?

[Pookster]

In my 83 burb, I have the old huge AC compressor (harrison?). I bought it from the PO, he said it needs a belt. (which means, the compressor isnt working usually!)

So I hook up a belt. There seems to still be some pressure within the system. I see the clutch kinda free wheeling,even without the AC being active. So then I jump the connector on the condenser switch. (now that I think about it, I jumped the condenser, not the switch! lol)

but it seems the clutch is producing heat. I think I need to replace the clutch. Any ideas on where I can still get parts for that unit? or should I just get a whole new unit?

too bad...

Darn!---I just scrapped a "long" compressor from the 73 307 I put in my van--it worked great too,but had sat awhile,and I had no use for it anymore(none of my GM trucks had AC)...I would have given it to you,had I known someone needed it...too late dammit!..

I think its better off to get the whole compressor-- if the clutch needs replacing,the whole unit has likely seen better days,-and it might be the compressor starting to seize up thats making the clutch slip and heat up.....
I'd look for a good one at a boneyard that still has a working A/C system,or at least still had pressure and freon in the lines..its not hard to swap the whole unit out,but you need special pullers and tools to replace just the clutch on one...

DOH!!!!!!!. This new BB just doesnt have the proper expression I need.

If you see one in a yard, let me know- Cause yards here dont have such items.

I am guessing you have an old "A6" A/C compressor. You can still get parts for it, but you will need a special puller tool (for A6 compressors only) to get the pulley off, and then get to the clutch and bearing. You should probably just buy a rebuilt one. Most every auto parts store carries them.
