Keymar, Maryland | Started charging up the old Deeres again since it got up to 90 degrees here. The 4440 charged up ok, and is cold but won't build any low side pressure. Has a new compressor and filter dryer. Is there an orifice of some sort up in the top that may be plugged?
The 4430, on the other hand, keeps pegging out the high side. Like 350 psi. Not necessarily overcharged, just seems like a blockage Of some sort. Would the filter dryer do this? | |
