I had purchased a case IH mx100, has 5.9 Cummins with Bosch pump. P Pump looks the same as the pickup version but with different governing systems the AFC housing is all different. Just looking to add a little power and smoke to wake up the tractor. My best guess is the bottom screw on the rear of the housing is where my adjusting would start? Number on the rear of pump is RSV500...1100AOC923R. Would like to know the opinion of someone who has seen such a thing before. When I bought the tractor I glanced, saw it had a p pumped 5.9 and there would be tons of info on it, but being the AG platform Im a touch lost. Like I mentioned before just in it for a little smoke to make it feel like a tractor, Thanks in advance!
