ditch the stock a/c compressor because im tired of of oiling it all the time,

Run a tank.
A small tank(s) can be mounted anywere. In the fender front or rear fender. , under the belly and can easly be emptied with an easy to reach remote draincock. Besides holding more air.
Finally finished connecting the separator and the oiler. It works PERFECTLY; a little turn of a ball valve immediately fills up the oiler.
I also made it so I can disco it and completely drain it, then fill it up with new fluid in a snap.
This is how I originally had it, but the location of my pressure switch made it difficult to reach
so I decided to switch the output somewhere a little more reachable:
I used an assortment of brass adapters, 1/8" from the bottom of the separator, bushing up to 1/4" pipe, and 3/8''ID tube.
The way it works is I flick the switch inside the cab which turns on the compressor. When I realize there is no more ATF in the oilers sight glass, I turn the ball valve and it then refills the oiler. Then I shut it off.
Sure as hell beats refilling and drainig, squeezing into tight spaces to do so.
It works absolutely perfect, couldn't be happier. Its a must for anyone running OBA off of their stock compressor.
Nah, oil filter is fine I designed my setup around it. I reach in front of my coolant overflow to change it since I have a vertical oil filter setup. No problem at all.
For anyone else doing this the condensor idea kastien suggested is good and should work just fine.
The condensor sees more than 150psi just about every time the ac is used in 60°f or higher temps (134a systems) and at 100°f ambient temperature 240-290psi is considered normal for a high side component.
The separator rests on some sheetmetal in front of the blower. Seems to be extremely solid, and since there is no constant pressure on it, I don't see it failing any time soon.

Yeah but removing the condenser also makes the engine run a few degrees cooler. That was my first priority when removing my AC system, which I did along with a CSF 3 core and a trans cooler. The OBA was an afterthought for me.
On my 87 renix, i took out everything but the compressor. I welded standard pipe fittings to the stock compressor fittings, and i am running 1/4 hyraulic hose to front and rear fittings and front and rear lockers. I have my intake running through a lubricator with slick 50, then out with a separator/regulator and then a pressure switch. the lubricator and separator/regulator are tool shop brand from menards. The only bad thing i'd have to say about this whole setup up is that it has low volume, hense the 5 gallon air tank in the back. When i first was testing the compressor it maxed out a 250psi gauge. As for emptying or attemping to recylce the old oil i just let the system build up pressure, push the little valve release at the bottom and let is spray a little oil/water and then just refill the lubricator. Thats just my $.02
Uh yea thats exactly how mines setup except I opted for the ball valve since its much easier to deal with.
Btw, the valve assembly worked it's way loose (I didn't fully clean off the nut inside the bowl that sandwiches the brass pieces to it.) The HF separator is really a piece of shit. Gonna have to upgrade soon.
Took it off cleaned with dish soap then alcohol, let it dry, thread sealer, tightened the shit out of it, hasn't budged since.
Now I jsut need to get quality male input pieces for my tools so the freakin lines stops blowing off every 2 seconds.
