I have a new to me john deere 4840 this year. When I bought it the A/c was working converted to 134a. Planting corn the compressor clutch failed. No big deal, got a reman delco, vac it down, add pag 100 and charged it up. Ran about 15 hours no prob and compressor locked up again. Ok, bad compressor? Got another reman delco, flushed system, replaced drier, vac down and recharge. Ran about 15 hours again and compressor locked up.. what am I missing?
Did you take the expansion valve out of the system before you flushed the evaporator? The aluminum nut on the evaporator seems to seize unto the steel expansion valve preventing its removal. Couldn't remove the expansion valve on my JD4250 without wrecking the evaporator. Replaced both when I converted to R132.
The Delco remans seem to have a bad reputation for rapidly failing. |
What am I doing wrong?
