how to tell if my AC Fluid is contaminated, my pump started makeing noise, in order to get a warenty on the AC pump i have to buy a new condencer and all, just want to replace the pump, but need to know if there is any way to tell if the bearing has contaminated the fluid or if it may have just been the clutch bearing that is gone, if anyone can give me any information it would be greatly apprecated..

In order to get a warranty on a compressor, you need to install a new accumulator-drier and an expansion valve. (Not condenser). When you remove the expansion valve, you will notice a screen on it that traps small particles. If it is clogged, you have internal contamination and need to do a complete system flush prior to installing the new compressor. If you do not, it will not last long!
You can also tell if the pulley bearing is bad, just by turning it with the belt off. If the problem is external instead of internal, you will not have an excessive amount of internal contamination, however, it is still a good idea to flush, prior to installing high dollar parts.

ok the internal shaft seems to turn free the pully, belt attaches to is whats draging and is the problem, is the bearing for it internal? not sure how to descibe it, but the part the clutch is on and only spinns when ac is on turns fine the part that turns all the time with the belt attached is whats making the noise and is hard to turn by hand

It sounds like your clutch bearing is shot. If it has not damaged the mounting snout on the compresser. The clutch assembley or the bearing can be replaced.
Without removing the freon. Just pull it off of the front of compresser.

The part for the H6 compressor that you described is normally referred to as the "clutch pulley bearing".

You need a clutch removal tool to remove the clutch and pulley assembly like the one listed in the link below. It might be cheaper just let a shop do it!
