I just bought this 3500 engine with 87hrs showing on the meter. It was on a water pump owned by a town. It has a MINIMEC (simms) inline pump and a variation of the newer 670 oil cooler. The manual with the engine says it's a on highway engine (truck) and shows this pump.   I don't anything to identify it any better. Opinions?------------- Nothing is impossible if it is properly financed |

| that should work great In my 220, when are you selling It(LOL) |

| I'd say it's age is from 1973 to 1975? because it's got the new style eng oil cooler and it's cast iron (square) so that would be similar to a 7030/7040 engine except for the Simms inj pump and center outlet (D21-210-220 style) exhaust manifold. |

Darrell, This engine is why I want to sell you the newer and cheaper 670 out of the L2 combine. As you see I don't need the L2 engine now. ------------- Nothing is impossible if it is properly financed |

Somewhere on this forum, someone commented that the 3500 MK II block was different than the 3500 blocks. What are the differences? ------------- Nothing is impossible if it is properly financed |

| 3000 series Mark 2 blocks began with the 7030/7050 tractor in January of 1973. Looking at the left side of the engine, there are no differences from pre-Mk2 to Mk2. On the right hand side, the engine oil cooler and filters are the major change (larger cooler and filters that are upside down) and the timing cover/front plate were changed to accomodate the newer DM-4 Roosa-Master injection pump system. The blocks were thicker in the walls that ran alongside the crankshaft for less noise and I think the towers of the inner structure that ties the deck surface to the mains are stronger to be more durable at higher HP levels. From the D21-210-220 engines that produced 150 flywheel HP maximum, they eventually had the Mk2 engines up to 222 flywheel HP in the 7580/N6 applications. |

| Something different about that turbo set-up isn't it? Whats the extra housing on the exhuast to the right of the turbo? -Wes |

| Just another variation of the exhaust system....that one goes from 3 inch to 4 inch and would be capable of supporting a large/heavy muffler unlike a farm tractor straight pipe. Pre Mk2 also had that available. |

A few more questions for Dr. Allis or anyone else. Is the Mark II block the same as the 670 block? Could it be possible this engine has the same injector tips as the 7080 tractor? The books says the tips are .375mm (0.0148") part 4029014-0 operating at 3800 psi. I have a lot of confidence in ARP rod bolts that are in the new AGCO packages. Would it be wise to change the rod bolts? I'm considering adding an intercooler and installing it in my 220. I'd like the model number to have the same designation (meaning) as the new tractors if you know what I mean. I also want a bullet proof engine. ------------- Nothing is impossible if it is properly financed |

| 7080/7580'S with AC injector bodies were .0148" four hole tips. Mark 2 blocks evolved into the 670 series....in other words they would interchange with no problems. I know 670 engines later on (1980-81?) had heavier/thicker main brg caps compared to older engines. Rods bolts were never an issue as far as I'm concerned, but if someone thinks they are, I'd bet it was a 7080/7580/N6 that ran 2850 rpm hi idle and had a bad fluid dampner on the crankshaft. I've never had a broken rod bolt. I always replace rod bolts with new when working on the bottom end as a precaution. Intercoolers on a 220 tractor in hi ambient temps will probably cause overheating problems because (if the intercooler is plumbed correctly so it actually works) the BTU's of heat you are taking away from the engine are more than the radiator was designed for. There is a reason why a 7060 has FIVE rows of tubes in the radiator versus FOUR rows on a 7040 and 7045.....the intercooler is why......extra row adds 20/25% more cooling capacity to offset what the intercooler is adding to the coolant heat. |

| Does the Dr. say in his last line that a 7040 doesnt have an intercooler? |

I beleive that is correct. Intercoolers on the 7060 and 7080,7580 ------------- Nothing is impossible if it is properly financed |

I just picked up an intercooler from a yellow industrial engine this afternoon. There is a 3/4" or 1" pipe plug in the waterpump of my engine . Could I plumb the the coolant feed to the intercooler into that plug? I haven't had a chance to check yet but I think the casting for the waterpump that came with the intercooler is a little different. I know Dr. Allis made a comment about the intercooler being plumbed corectly. ------------- Nothing is impossible if it is properly financed |

that is where I plumed mine on the puller, but I am not sure that is water under pressure. I think it is still suction, but have been wondering this all summer. I use it for such a short time, dont know if it would do much anyway.

Look at a factory set-up.....you need to get plumbed in exactly as they did it at the factory to be sure coolant flow is correct. Coolant comes out of the water pump and flows into the intercooler and thru it front to back and then turns around and comes back to front and out through the thermostat hsg back to the radiator. Even the early 7030/7050 water pump impellers were changed (deeper fins) to promote more water flow.. |

| hi calvin,it was a pleasure to meet you at the laporte show.if you give me the basic catalog # off the eng.tag i can tell you if you have a automotive (truck) eng.Jeff Heitman has access to the eng serial # archives from harvey-if you can give the serial #,we can tell you when it was built,application,who ordered it,options ect.the only bad thing is it takes about a month or so to get a responce.
