Hey guys. So I was wondering is anyone on here has or knows how to turn your AC pump in to a air compressor. I have a 02 ranger FX4 and I recently got a air locker for the front. but before i get it put in i need a way to turn the locker on and off. so this is what I am thinking. If anyone can school me on this it would be greatly appreciated.



Cheers
Chris

 

Your Ranger A/C compressor does not have a crankcase sump and relies on oil mixed in with the refrigerant for lubrication. It will not last very long as an air compressor. Other brands like York have made A/C compressors w/ a dedicated oil sump. These are relatively cheap used and that makes them a popular conversion compressor for onboard air.

I don't know how much air volume the locker needs but wouldn't it be possible to use a small electric compressor and storage tank? It should be lot easier than setting up a York conversion and you could keep your A/C too.

 

Could I not put in a oil air separator, to help keep it lubricated.


As for the AC i never use it.

 

I have heard of some people adding an inlet oiler to the compressors that don't have a sump. Then you'd need a separator on the outlet side unless it's not important to the application to have oil free air.Try Googling "onboard air" for various how-tos.
