| What would be a good replacement 440 motor for the 555 besides a 555 1st motor broke crankshaft it was repaired broke another then they replaced with different 555 that one weent about 200 hrs crank broke between 1st and 2nd main and that's how we got it thinking about a 444e out of a bus and turn the power down |

Why did these engines perform so poorly in these tractors? What did the Steiger tractors use?

| According to Tractor Data, the Steiger Bearcat, had a Cat 3160. I would think you could put in 3160, or a 3208. |

| I have a 6v92 that’s going to be going in mine. I like a 3208, but I would look for a 3208t with the 3 ring pistons if you go that route. Been good motors in trucks for us, but 335hp with the 2 stroke and there tough as nails. |

Is it turboed and did the crankshaft get turned down at all? Have a v504 in our versatile and it’s been a tough little engine. Heard if you grind the cranks at all they will break easier in the 555 and that the 555 liked to break cranks when turboed. I would maybe look at a IH 466 truck engine. Bell housing looks similar and the 466 is tough as nails, and the truck engines are cheap and dime a dozen. I also do like the 444e idea. Would be cool and they are indestructible. Reliable power. Not sure how you would turn it down being it’s computerized, but I think our ih 4700 is only rated at 210 I think, might even be 190, would hold up to that just fine I would think it you treated it correctly. |

International dealer can turn it down with their computers told me after find the plug under the dash and pull that harness out and plug it in and then they can set it for whatever horsepower we want RPMs we want if you go much above what it was originally horsepower wise Dropbox is probably the next week is link ------------- You can wash the dirt off the body but you can’t wash the farmer out of the heart and soul |

May be worth considering the rpms of the 555 vs the operating rpms of a replacement motor. I think the 555 ran pretty high rpms so any difference may really change the transmission speeds ------------- Orange & Silver still earnin their keep on the farm: R62, Series IV D17 nf, 185, 6080, 6080 fwa, 220, 1968 D21, 7045, DT240. |

| That 555 Cummins was rated at 218 flywheel HP @ 2800 RPM, so high idle was probably 2900 to 3000 RPM's no load. |

I don't know much about engine conversions but why not an engine out of an N7. The 516 in our dozer is fuel efficient and one of the best starting Allis engines I've ever been around. ------------- -- --- .... .- -- -- .- -.. / .-- .- ... / .- / -- ..- .-. -.. . .-. .. -. --. / -.-. .... .. .-.. -.. / .-. .- .--. .. ... - Wink I am a Russian Bot |

| I'd guess the 516 is physically too long to fit where a 555 was. |

| I actually bought a 3306 to put in mine and to go with a 6cylinder in-line you would almost have to stretch the frame 10”. It would fit if you could scoot the transmission back a little, but the driveshaft is already almost too short. That’s no big deal, but I didn’t like the way it would look. I bought a 6v92 out of a semi for $500 and figured with 100 extra horsepower you wouldn’t notice the low end torque as much, but the 555 or 3208 don’t really have any either. The 555 isn’t exactly quiet and with the turbo and a set of resonators I don’t think the 6v92 will be bad on noise. Got to be better than driving the cabover it came out of. |

Two things wrong with the 516 length and rpm don't think the 516 would like 3,000 RPMs very well ------------- You can wash the dirt off the body but you can’t wash the farmer out of the heart and soul |

IN my two 440's, I NEVER ran more than 21 or 22 hundred!--- never had a problem. Mine will tach at 3,300 IF ya don't watch them! --- NO way I would ever run one that hard! You can tell at 22 hundred that everything is smooth, engine purrin' along and not boggin' down, so that's were mine run! I would go for the Detroit if re-power was needed! thanks; ac fleet

Everyone dogs a 3208 but in reality they are a small engine that was slways overworked in big trucks. 3208's are excellent in medium duty trucks. In a stieger bearcat 2 they made 225hp. Steiger didnt regear the high rpm v8 tractors. Thats why our bear cat will run 30+ mph down the road |

| I had a 3208 in a Cat 225 excavator chasis with a 50 foot delimber boom mounted on it (logging) When I sold the machine it had 12000 hrs on it, I did have the Cat shop pull one head for a antifreeze leak and do injectors at about 8k hr's. It was easy work for it on the delimber but anyway I was very pleased with it's service. |

| We had a 3160, and a 3208 in Field Queen choppers, I always thought they were good luggers, but they were always run at full throttle. Truck application might be quite different. |

I had a 6V92 at 335 hp and a Formula 290 Cummins both in 78 Ford heavy tandam straights. The 6V92 would lug just as good as the 290 and actually had a lower RPM point for a down shift. Now my 3208 in a Ford single axle wouldn't pull a hen off a nest. I've seen a 6V71 in a 440. ------------- Nothing is impossible if it is properly financed |

Steve: just the idea that you think a 2cycle like the 6V92 or if you want a do-over even the 6v92T can have low end torque is halarious  and tells me you are easily impressed. I have been driving trucks for the past 45 years now and just the fact that most all of the 2 cycle Dogtriots were mated to 13 speeds or more whereas an engine with GENUINE torque may only have a 9 or 10 has a lot to say. How about those 300+ Macks with a 5 speed, now that’s torque. I have also operated many FieldQueens with the 6v92 and it is a good engine within it’s capabilities and running at top governed RPM. However any 2cycle will fall faster than a barrel over a waterfall when it sees a hill. The only time you can let up on a Dogtriot is when you need to downshift, then it’s right back on the floor. I have driven many large CID gas engines back in the day that could be considered to have torque, such as a Hall-Scott big Walkashaw and even those V12 GMCs , they where fun with the 5X4 and for their time impressive.Now the idea of replacing a 555 rated at around 200HP with any engine of 300 or so is just asking for drivetrain issues. If you want to suggest a 2cycle to replace rge 555 just so you can listen to that annoying 2cycle wine, a 6v53 or derated 6v71 would be more suitable. ------------- If it was fun to pull in LOW gear, I could have a John Deere.

| Comparing a 6v92 in a semi hauling 80,000 pounds up a hill, and running wound tight in a tractor are two separate scenarios. The 6v92 was probably underpowered for the days of 3-400 hp truck engines, and I’m sure will feel gutless comparing to a 855 or 3406. Even the 8v92 wouldn’t keep up with the torque capabilities when set at 450hp. Same holds true for the 3208, of course it’s not going to feel very big in a medium duty truck with a 54,000lb gross. We’ve hauled a lot of grain with a 3208 natural in a topkick at that weight. The truck will fire right off into the negative temps and runs great if you keep it wound up like a Detroit. A lot of people knock a Detroit, but they are a fine motor that was often pushed beyond what it was capable of and held together. More than one could say for the 555 Cummins. The 3208’s major downfall is that it’s sleeveless and to overhaul it you need to strip it down and bore it over to press in dry sleeves. I’ve done a lot of research on the driveline of the 440/bearcat and it is well capable of holding 350hp. Same tractor as the wildcat and bearcat III. Several 440’s were converted to the 6v detroit whether it be a 71 or 92 series. I’m not going to run mine hard, but I don’t think any problems would exist if you did, especially in the higher gears. If anything would go I would suspect the transfer drop box to be the weak link, but it’s a pretty solid unit. |

You sure on them numbers? The 6-71N in my first truck was advertised as 600 lb/ft,238hp @2100.Don't know the lb/ft rpm.Back then a 237 Mack was at 900lb/ft and it showed!
