Hi everyone, I operate a 2016 Cat 140M, in the last month I have been final trimming a pad running north south whenever I run south fumes enter the cab from the roof airconditioner inlet top back left corner ,depending on wind direction normally from the northeast. My biggest concern about this is if I can smell exhaust fumes there has to be carbon monoxide entering the cab as well. i got our mechanic to block off the inlet and no more fumes. Now my question to any other Cat 140m (may happen on other M models as well think cabs are all the same design ) operator have you ever had this problem? any comments
