when you consider a Blue Toung 3 compressor from Opposite Lock is only about $400, why would you bother doing the aircon compressor. i have two blue toung 3's and they are bloody fantastic

Alex, I've used an old aircon compressor as an air pump in my vehicle for the last 6 years (living in Sandgroper country it gets used a lot). The lubricant I use is any of the Teflon additives for engine oil. The compressor dosen't take much to fill up and it dosen't use much.

Alex, I have been looking into this a bit myself and have come to the same conclusion. On the basis that you either already have an old aircon or can pick one up for next to nothing. Again assuming you have the facilities to make up the new brackets, then why would you spend hundreds of dollars on buying one.

I am also thinking of fitting an old aircon to my diesel 80 series wagon (as I have one off an old vehicle). However, there appears to be very little room. I understand it may be necessary to move the existing aircon to make space. I also guess I will need to fit another pulley in front of the existing pulleys on the crank. I would appreciate any help or guidance I can get for the above fitting. Anyone?

Good luck with yours Alex

Cheers Peter
