There's an old 4wheeler write up on how to do the long canister older style ac compressors to air...I have it somewhere...if I find it, mabey I'll scan it in for ya....basically though all it said was to put an oiler in front of the input and a de-oiler coming out of the output...to lubricate the thing, because unlike the york, this style is not internally lubricated, it was lubed by the lube in the freon...
