G'day Cat man. We have a C9 in our challenger 670 combine
yes we are trying to diagnose the problem at the moment.the machine will work under load and 2200 rpm for could be 15 minutes to 2 hours to 10 hours then looses revs oil pressure light comes on temp light comes on . When you try get 2200 rpm it can't hold it and blows lots of black smoke rpm ranging from 1800 to 2400 . I have clean the air filter , put on new primary and secondary filters , blown air back into the tank . When you turn the machine off then back on it sometimes fixes it and away you go but not always. So I'm thinking maybe it's electrical so have cleaned all the earths I know of. Next step I was thinking was to inspect the wiring harness and try flick at the oil pressure sensor and see if there's a test we can do . Would appreciate any thoughts.
