D21 Superfarm Question
|
Anonymous User
|
I am interested in setting up a D21, with the 516 N7 engine now running Prostock for the Superfarm class. Does anyone know any problems allowing the 516? It is now at about 600 cubic inches. I want to check before I buy a charger.
Any help would be nice, I am located in South East Michigan. |

The 516 isn’t legal in the SF class in the NTPA, I’m not 100% sure but I don’t think PPL allows it as a replacement motor either.
To be legal in the NTPA it either needs to be a OEM replacement as designated by Agco, or the block must be able to swing a stock crank for a 426 without any modifications to the block.

Do it. Living in SE Mi you can contact Scott Doty and he will give you a yay or nay. I think they will allow a DT 466 IH as a replacement for an AC so I don't know why they wouldn't let you run a different AC engine.. |

Technically you can’t run an IH DT466 in an Agco, but you can run a 40 Series Detroit. People can argue all day long that the 40 Series and a DT466 are the same, but even if they were 100% identical the DT466 would need to have a serial number after the Tenneco buyout of IH to be considered a legal replacement.
Last I knew an IH DT466 in an Agco is 100% illegal in the NTPA. Jake Morgan Owner, PULLOFF.COM Independent Pulling News This page is a free service. The cost is covered out of my pocket.

I live off of ridge rd in britton. I guess I should talk to scott doty and see what I can do. The 516 was used in Combines, not tractors. I know there are a few people running these mostly in the ProStock class. |

I am only planning on some local events, not looking to compete in the G.N circuit. I just want to go have a little fun, and make some smoke.. I have always been around the orange tractors and that is what I wanted to start with. |

What would be considered local pulls for you? We pull north of you in the "thumb" of Michigan with the TTPA. We run by the NTPA Superfarm rules. If your building to fit those rules, you'll have to check us out and come pull with us sometime. It would be nice to have another D21 around. Some of our pulls wouldnt be too far for you either. Good Luck! |

I think I know where you're at . I'm a couple of miles from you. Would you find if I came down and had a look some time. Not sure what they would say about that motor since its not OEM. Good to hear of another horse in the neighbor. Hopefully I'll have one in my stable in a couple of years. |

Just wondering if you talked to Doty yet on your motor. Is that 516 an actual AC motor and is that the only application the N7 combine?. I can't seem to find out much info on that beast. |

Drop me an e-mail at artwooden@aol.com and I can forward you a pretty good pic or two of a 516 industrial power unit. The N7 combine parts book also has the motor parts in it. It is an extremely long in the tooth engine,in terms of age, with multiple variations. Early models appear to have power cell heads, late models have somewhat different heads, on the turbo'd versus non-turbod models, with the heads being twin heads on a six cyl motor.
It appears the rod bearings are 2.75, like the 426 ac, the engine looks taller, not much wider, and somewhat longer. If memory is correct, parent bore for sleeves is 4.998, and with stock stroke being in the 5.5 range,there is considerable room internally to add up to another couple of hundred cubic inches! |
