The compressor wheel on my FJ62 AC has died so I'm going to take it apart and try to fix it.
Has anyone ever done this before or can offer any advice?

Are we talking about the compressor clutch-where the belt rides?
There is a bearing inside the pulley, that can be replaced, although it will need to be pressed out and the new one pressed in. I believe the bearing measures 30mm ID, 52mm OD and 22mm wide. Depending on the production date of your 62, you might be able to buy a clutch assembly which would have the pulley, hub and coil, then it would just be a matter of removing the old and installing the new.
Good Luck!

If it is just the bearings in the pulley do NOT remove the A/C compressor. Recharging the A/C in Latin America is a hit and miss proposition. I have found one shop that can do it correctly and I think it's because he is US trained!
You need snap ring pliers to remove the pulleys after to get the clutch off the front. There's 3 or 4 snap rings in there. Any of the bearings should be replaceable.

With a smallish dose of mechanical ability and the proper tools, you can replace the pulley/clutch assembly. I do not recommend overhauling the compressor without some experience on your side. You will likely save money and avoid frustration by finding a good used repalcement. Ask me how I know.....

Oh I already took it off. I tried to save some of the refrigerant by folding the hose in half and pinching it with vice grips... doesn't make a hissing sound so seems to be working! The damn thing was mostly non-functional anyway, and at this point nothing more than a slight drain on my mileage just having the pulley on. I figure if I can't recharge it, I'd be glad to have an awesome on-board air compressor at least. It's better than non-working AC.
Also, in Ecuador there seemed to be good looking AC shops all over the place... of course I never tried one, but now that I know what to be careful of I might be able to find one that will do a good enough job?...

You cannot save the refrigerant by folding over the hose. You'll end up damaging the hose if you haven't already, besides you need to evacuate the entire system anyways and you cannot do it when you're trying to save refrigerant in the system.
Even a decent looking shop can be a joke. I'd tell them you want to watch the entire process and then watch it!! I had a guy that came to recharge my system after I had my frame swap. He came complete with a vacuum pump so I assumed he knew what he was doing. Even so I kept an eye on him. He started evacuating the system with the compressor and I told him I wanted the vacuum pump on it later, "Yes, yes!" he says, 2 minutes later he was charging it up! I was VERY pissed and I told him so. He said, "Don't worry, I know what I'm doing!". I barely worked, ie: the air was slightly cooler than ambient. I had to have it evacuated and recharged elsewhere as I did not want him near it again.
