JJJZJ said:I ran the search and there isnt much about doing OBA on here. Ive got A/C on my 85 4runner with the 22re and would like to convert it to OBA. Can any of you guys get me going in the right direction with writeups, tips, pics, etc? thanks.
BCGPER said:I'm using my stock 4 Runner's A/C for air, and have been for a few years now. Toyota used a rotary compressor, so you'll have to have an oil source to keep it from seizing. Also, the tank will be a must, to remove the oil and moisture. You'll need a pressure switch to disengage the clutch once the system is up to pressure also. You can use a PRV, and just dump the excess pressure, but pressure switches are pretty easy to come by, and save a lot of wear and tear on the compressor. If you want to look at mine, you're welcome to. Also, I have a tank here you can have if you want it.
I just did this on my toy truck. Worked out great. If your ever in utah county your welcome to look at mine. Definately use a tank. The little rotary toy compressors put out an amazing amount of air. Used an air tool oiler, water separater combo i got at harbor freight for around twenty bucks for the oil source and to take it out after going through the compressor.BCGPER said:I'm using my stock 4 Runner's A/C for air, and have been for a few years now.
