Default Noisy A/C compressor pulley bearing

I have a '97 Pathy, and the bearing on the pulley in front of the compressor is making a constant grinding noise, whether the clutch on the compressor is engaged or not.

I was under the impression that the pulley could be pulled off and replaced, but a local mechanic is telling me that it needs a whole new compressor because it's all one assembly. The compressor was replaced by Nissan under warranty at about 100k miles, about 60K miles ago, and works fine, A/C blows real cold, clutch engages and disengages no problem.

I was just wondering if it is actually possible to replace just the pulley on the compressor, without having to evacuate the A/C system, pull the compressor off, and then re-charge the system? It just seems rediculous that the entire compressor would have to be replaced, when the only thing wrong is the bearing in the pulley.

Thanks.
