Ac Compressor to Air Compressor??

I have a ports to charge, there r12 that have been retrofited to r134a.

The compressors look very simular, exept for how it mounts and where the line comes out. Hope my Sanden SD708 will work as a compressor.

mine has a bolt right on top, if you take that bold out, you put the oil there, and your good to go. If you take a zip tie you can put it down in that hole and see how much oil is in it, it just has to curve going in to get to the crankcase.

Shouldnt u also run hard line all the way back? Just because I was told the air that comes out gets pretty hot, im gonna try it on my compressor, after reading like 6 of these threads why not my compressors not diong nothin anyway.

thats why i got the viair leader hoseand i cound find anything saying if the 708 was a self contained system or not, so i said screw it and ran the oiler

If you dont mind me asking, do you happen to know what size taps they used for each of the two holes?

its in my original post

I meant the actual size of the tap. I need to know the size and thread count of the 1/4" and 3/8" pipe fittings.

oh,sorry i just took it to the machine shop

It needs to be a Pipe tap, since npt's are tapered so they will tighten, so you need a 1/4" npt tap and a 3/8" npt tap

What about the on/off factor? Did you just run a wire from the pressure switch to the original clutch wire?

the wire that comes out of the clutch needs to be hooked to the pressure switch, then the pressure needs a reliable 12v source. perferably one that is off when the key is off.
i got mine installed, i'll see if i can get some pics later
