ND | 60 and 70 series Deere's use a orifice tube instead of a expansion valve. I would look at the vicous fan drive to make sure you are cooling the condensor enough. Also make sure you do not have a exhaust leak and blowing towards the A/C housing, have seen that happen. You said a couple of compressors were put on, I hoped they flushed out the system every time so there is not too much oil in the system. These A/C systems do work on these tractors if the tech knows what he is doing. | |
