aircon compressor - pics
aircon ran fine but then the compressor started making a rattle noise from the front. it only makes the noise when i turn on the aircon so im assuming the bearing inside the clutch has worn. is it easier just to buy a new compressor or is it better to have it rebuilt when this happens ?maybe is just something loose? i know absolutely nothing about them.... i put a pink arrow on the picture to show the area where the noise is coming from ..please tell me of your experience..

It's known as the R4, a radial compressor with 4 pistons, the things are normally noisey to a certain extent, but since i'ts obviously out of the car, I would replace it, and flush the entire system out, blast it good replace the valves the system should be ok....
I have seen good rebuilts on the R4s and had bad brand new ones from GM, so for the money get a quality rebuilt, now how you tell a GOOD rebuild from a lousey one going IN, is a good question....
there probably nothing YOU can do to fix it though....

thanks for your help blokes. turns out one of the terminals on the compressor was like a loose tooth. it was just flopping around and cutting the power on and off . luckily i noticed it just before i had the thing drained and rebuilt. hey just out of curiosity a few of my mates have never bothered with getting a new dryer/accumulator and even left it lying around before re-installing it and they,re air ran fine. me on the other hand did buy one and put it in so what can go wrong if you take a short cut and dont use a new one?

If your's is an R-12 system, give serious consideration to changing/converting your system to R-134. R-12 is very costly and R-134 costs a fraction and keeps the environmentalists happy. Another trade off is R-134 doesn't cool as good as R-12, it just takes a bit longer to cool down.
