ac compressor replacement

Hello,I'm trying to fix a problem with the ac compressor on a 1989 Olds regencey 98.It started with a noise coming from the compressor when ac is off.So I started researching..thinking i could replace bad clutch bearing..I removed the clutch and attempted to remove bearing..but that did not go so good. So now im wondering if i just buy a salvaged ac compressor and switch compressors..did not empty refreg before removing clutch.compressor still attached.Do you have any suggestions?

I would never ateempt using either a used part or a remanufactured part for this. The risk of failure is way too high.

Yes I know its not good to use salvage parts but its alot cheeper..I did replace the compressor and that still didnt fix the rattling sound..I finally tucked my tail between my legs and ask a mechanic to listen to it..He sez its the hamonic balancer..Havnt done this job before either. So now im researching this procedure..I have a book on this 89 olds and it suggest I use a big screw driver wedge in the teeth of the back ring gear..well it also states that there is 219 ftlbs of torque on the center bolt of the vibration damper or harmonic balancer.my question is will the teeth on that ring gear hold up to that much torque? Has anyone else done this job?......Thanks for any and all input

It should be easy with HD air tools. It's really just a big pulley and they do use rubber which can separate. Should only be the crankshaft bolt and a puller needed for most all.
Tricks: You can lock the flywheel (ring gear) or see which way engine turns and put a strong socket and flex bar on the bolt if correct. Duh - if not don't try that and if you do position tools out of harm's way. Watch out - a starter motor is stronger than you would think!

Your also going to need a puller and installer to get it on and off the crankshaft.
PS, on your comment about used parts..............
It's only cheaper if you only have to do it once. It's a lot more expensive when you have to do the whole job over.
