Drill a hole in the bottom of the compressor"


How do you get your drill "under" the compressor?

I found sticking a 1/4" plastic tube down in through the suction port into the bottom of the compressor and then sticking another just inside the suction port. Seal around both and blow nitrogen (slowly, very slowly) through the one that you put in second. The pressure will force the oil out the other one. make usre you collect it into a container as mentioned to recharge it with the same amount of new oil.
