A/C compressor cclutch removal

What all is involved and what tooling (special) is needed to pull and replace a clutch on a AC compressor. Vehicle is 1990 240SX.

I have a Chiltons manual, but have yet to find a proceedure for removal in this manual or a reference to the freon type. Is it R-12 or R-134a.

I believe the problems in my sons AC is a bad clutch as its noisy and binds, when turned by hand. Previous owner actually cut the belt off the car so it would quit making noise. System still seems to have freon and has pressure, so could the clutch be removed from the vehicle while its still hooked to the refrigerant lines or does it have to come out. I figure this would be a cheaper way to possibly fix his AC, and if the compressor did turn out to be bad, I could always munt the new clutch on a compressor that I can get without a clutch on it already. Looking for the cheapest way to try, and without a compresssor can't do much troubleshooting, and no sense in buyng a compressor when its just a bad clutch.....considering what each of them cost.

Still looking for a belt to slip on it just to see what it does do under power. No one other than NIssan dealer has it in stock, and I refused to fork over $38.00 for a belt..Advance Auto is backordered, so its a waiting game for a belt.
