We have an 8030 that seems to be lacking power. Thinking about taking pump in to get checked out. I was wondering if the 8030 & 8050 had the same engine. If that is so than we could turn up the pump to put out 150 hp. What do you think? ------------- Thanks & God Bless Dennis |

8050 had an intercooled engine (670I), don't think the 8030 did, pretty sure it had the 670T (only turbocharged). Hurst ------------- 1979 Allis Chalmers 7000 5800 Hours |

| Should have the same pump, should be a American Bosch Model 100, 13mm pump, unless 8030's & 50's had 11mm, not sure, but anyway, the top cover on the pump, should be 4 1/4 inch bolts, take them out, pull cover off, the screw will have a 7/16 nut, and have a flat head tip on the end, loosen the nut and turn the screw out a 1/2 turn, or 1 turn, depends on how much power you want, i think its 50hp and turn, or in that area.Good Luck, Carl |

ALL model 100's used on 8000 series AC's were 10MM.

Correct. If my memory is correct, the 8030 only had a 2 pinion differential while the 8050 had a 4 pinion. I can't remember if the planetaries were the same or if the 8050 was also wider than the 8030. Increase the hp at your own risk. ------------- Mark B10 Allis, 917 Allis, 7116 Simplicity, 7790 Simplicity Diesel, GTH-L Simplicity Ignorance is curable-----stupidity is not. |

| 8050 has a larger (more tooth length) ring and pinion, 4-pinion differential and final drives that are the same width, but faster gear ratio. If the injectors have 4,000 or more hrs on them, replace the tips before you start increasing the fuel delivery of the injection pump. When those Bosch injectors wear, they will increase the smoke levels AND the HP drops, and increasing the fuel delivery only makes the smoke heavier and does not increase the HP of the engine....been there.....seen it!! Adjust new injectors to 3600 psi instead of 4,000 psi plus as the book says. |

This 8030 does not smoke at all. When you load it down the exhaust stays clear. ------------- Thanks & God Bless Dennis |

Will these engines start better in cooler weather if the injector pressure is set at 3600 psi instead of 4000 psi.------------- Fred Dunlop, G,B,CA, WC,WF, 3 WD45`s,gas, diesel and LP,U,D10 series III, D12,D14,D15 SERIES II,D17 Series IV in Gas and Diesel ,D19 GAS and D21,170 185,210 ,220 an I-600 8070 fwd, 716H and 1920H |

the head in your pump may be worn out! We have seen several M100's lately that have worn hyd heads, so fuel delivery is low, but they still start. have you had tractor on a dyno? sounds like the pump is due for rebuild.

I wonder if today's ultra low sulfur fuels are causing more pump and nozzle wear in the older units not designed for ULSD?
