I am in the process of adding AC to my sr20 (texas is hot as HELL). The compressor I bought is in great shape, just dirty. When i spin the front (not the pulley) i can hear the compression chamber activating.

But the problem is when i spin the pulley by hand its super smooth but i can hear a sort of grinding ( this is a super light grinding noise like little hard pieces of dirt) should I take the pulley apart? or should i leave it so when I put it on with the pressure from the belt, it will go away? thanks guys ahead of time
