Hi all,
Any air con gurus out there?
I have a Cat challenger 875c and have just replaced the compressor drier and TX valve. (Front seal of last compressor failed)
after replacing the parts I vacuumed the system down and checked for any leaks. Once I knew the system was tight I put 2.2kg of r134a in it according to OEM stamp.
Once working the tractor again the air started to feel warm. I put my gauges back on and found that when the compressor cut in, the high side went almost instantly to 400psi and cut back out again. It would stay cut out for 10-12 seconds then cut back in and go to 400psi again. This would keep repeating and the air was not cooling.
The condenser is spotless and airflow through it seems to be good.
Any ideas?
