Ok, I fixed the AC on my 7020. Very interesting that I only could put 24 oz of 134a in the system. We had a 90 degree day yesterday and the head pressure was 200. It does get cold for sure. Two cans of 134a just does not seem like much. Of course I put a brand new AC belt on, it broke while charging the AC and got tangled up in the fan and broke the shround. I am going to try a gates belt next, not having much luck with the agco belts.
