1. I first located an A/C compressor from the junk yard with mounts. I had them mail it to me and they forgot to put the idler pulley with it. I called them back and they gave me too hard of a time to mess with it, so I did my own mods to make it work.
2. Unbolt the battery terminals and remove the alternator and its brackets. Install the A/C compressor mounts as well as the compressor its self. Then using the new brackets, mount the alternator. When I got this far, I realized I needed a double pulley for the alternator. I found one at a junk yard for $3. The shaft size was smaller on the new pulley, so I had a machine shop drill it out. The pulley must be very close to ballanced or the bearings in the alternator will go out very quick. With this setup, I had to have a custom pulley/belt system. It is not the best in the world, but for as much as the compressor is used, there will be no problem. The only belt affected is the outside belt as well as the compressor belt. One belt goes around the crank, water pump, and the alternator. The other runs around the compressor and the alternator. Kind of questionable? I thought so myself, but I have had no problems with it and the output has been awesome. No problems with it yet.
3. Next was the fun part; building the tank. I bought some 4" PVC pipe and used it as the tank. It is ratet at 220psi and my pop off valve is at 170psi, so I should be ok. Make sure you use Teflon tape on all threads or leakage may occur. On the intake of the compressor, I installed a filter. I got it at Napa. I think it goes on a lawn mower or something like that. On the output, I connected the air hose that runs to the tank. In between there, I installed an in-line filter. This is to get out the oil and dirt that might have missed the first filter. On the other end of the tank was a diaphram which had the 170psi pop off valve on it, one line going to where ever on you truck, an air guage, and the on/off regulator. I set the regulator to turn on at about 90psi and to turn off at 150psi. I wired the regulator so I had a manual on/off switch in the cab. This would offer me two things: a safety switch to turn the compressor off in case too much pressure was built up, and I am able to keep it turned off when I want and am able to turn it on only when needed. It saves the life of your system. I know someone has the question about how to keep it lubricated. I just put about a tablespoon of compressor oil in the intake about every couple of months. It really depends on how much you use the compressor, obviously.
I hope this info helps eveyone out. It has greatly helped me out. There are still a couple of other options you can do that will be very beneficial to your system, I just left them out for now and am going to put them on within the next month. Here they are: A pressure regulator on the output of your tank that regulats how much air runs through the air lines to your tools. These are cheap, about $15 at Lowes or you local hardware store. Most tools run about 90psi. This regulates the pressure and keeps it at a constant 90psi and not 150psi like the tank is set at. This could dammage your tools in the longrun. Also install a one way valve inbetween the compressor and the tank. This keeps the pressure off of the compressor. This enables the compressor to start at no load to work against, therefore extending the life of your compressor. One more Idea. Try to find a way to install an automatic oiler on the intake so you don't have to always take the filter off and oil it yourself. The York compressor has an oil reservior that it runs in, I think. If you can find one of those compressors and use it, that is a good alternative to the oiling.
I hope this helps some people. If you have any ideas for the system or anything else that is a good idea, let me know. Contributions welcome.
