| Have a 1991 Case IH 9270 with 855 cummins rated at 335 HP. Would like to turn it up a bit, maybe to 365. Anyone know how, or maybe a reason why not to? I think the only difference between a 9270 and a 9280 was the fuel setting but I am not certain. There maybe more differences between the two engines than the fuel setting. Maybe someone can set me straight on that. Thanks in advance for any help. |

Southeast Florida | You can take it to 400 hp with a few cranks on the smoke screw. |

| Is this something that can be done on the tractor or does the pump have to be off and taken to a diesel shop? |

| I've never done one... but I beleive it's as simple as turning up the fuel pressure on a PT pump. Should be quite simple. It's a long time since I read up on pump theory but that info shouldn't be hard to find in a good diesel mechanics book.

Southeast Florida | A good Cummins mechanic can do it on the tractor but it'd be a guess as to where it would be set at. I having a complete brain fart right now as to how it's done on them too. Been a long day beating around the cab of neighbors Versatile getting his wheat planted. |

Coloma WI 54930 | From the factory the 9280 has lower compression, not sure if that makes any difference? Doug |

Mississippi Delta | I'm kinda the same as FVF, but we used to change out the "buttons" in the pump. Seems like a 9370 came with a #17 and we put in #10 or 12's. Also put a one way valve on what I guess was the aneroid line. Not sure what it did, but sure helped. Seems like it may have made it think you more manifold pressure than you really did, so it would shoot the fuel to it. Not 100% sure about all this as that was ten years ago, and we have long since gotten rid of those tractors. But we did have them juiced up pretty good, (cummins mech. said over 450 hp by his guess) and put over 5000 hrs on them pulling pans, never had an engine problem, just rear ends, and drivelines. Some of the steering wheel holders we had in the seat could tear up an anvil with a rubber mallet! The rear end problems were finally slowed by putting 90W in the front and rear and unhooking that silly system case has on them. |

WCIN | Old days without changing buttons was putting in a "stinger". That was screwing in the fuel pressure control valve == more fuel pressure. That's what the selective buttons did. Thickness of the buttons, meant different spring pressure------different fuel pressure.
You should find a dude that knows exactly what your senerio is and go from there. Try your local wrecker service.

North End I-15 | The Cummins warranty was good with a 10% turn up . Lot of the fellows with a 946 did that .Rather than buy a 976 . Versatile had tough drive lines and super planetarys . Weak point was the axle housings . Never heard of a blue one breaking but the red ones in a power hop would . ( in this area) |

Texas | ill see if i can find my old books there are shims to set up rpms ,the rail pressure needs to be set to 100/200 if i remember correct .
got my curosity up now,ill check. |

Grandfield, Ok. | A pressure gage on the charge line an a screwdriver will let u set it up with some degree of knowledge. |

East , central Illinois | look on the pump where your throttle lever is on a splined shaft. below is another splined shaft with nothing attached to it. is it hollow on the end if so a flat screw driver inside shaft .remember out is up. ours had a small like a steel ball in end of shaft had to lightly drill ball out. remember OUT IS UP |
