Ok, humor me here. I am just wondering if you can install a DT466 into a Farmall 400. If you can what all has to be done to get it to couple to the transmission? It would be a project just for fun.

Well depends on what kind and how good of Barnyard engineer you are and what all you have to work with . It will not be a direct bolt in and there will be some machine shop work required , some sheet metal work . Nothing that a big check book won't cure . we have done some wild things and a couple guys soth of me have done some crazys things , one is dead now so can't ask him. as they have installed aircraft engines big V 8's and even a sherman tank engine in a H . Yea it is cool but Like with V 8' and V6's out of cars the torque curve is all wrong for the gearing on a tractor . Most car and truck engines make there torque above 3000 RPM and fall flate on there face down in the 2400 RPM range and below . Now with a DT 466 in a 400 you are turning the engine at close to 2/3rds faster then the org. engine . Just sayen .

I'm not saying I will do it for sure or not but the thought of being able to say "ya I built that" would be fun. The more I read on it the more I think it is possible. I don't need it to farm with so it would be more of a toy. I always appreciate your knowledge and experience.

You would have to use the flywheel off a 966 and the clutch and pressure plate , frame rails would have to altered The back engine plate may need some tweaking , I can't picture in my head on how the fan would set . That would take some thinking . The radiator would need to have more cores for cooling , not sure if a 400 diesel would fill the bill or not as it had one more row of cores then a gas. If i can stuff a 8.3 Cummins in a 2150 Oil all over with ft assist where we had to do a little reenginering of the oil pan to clear the drive shaft but not loose capacity . Now as to having clearance for the turbo under the hoods ???? Yea i have stuffed in different engines in stuff some fit like a glove and some needed lots of re enginering with lots of fab work to make them work. That was many moons back and now i am happy just keeping them running.

With the right motor plate and clutch lengthened hood and frame it will go in.

You help me put a GMC V6 in my M,I'll help you put the 'DT' in your 400.LOL. There is a 560 picture a few posts below with a 436/466 in it. So I'd say yes it can be done

If you were closer I'd help lol... I was reading last night how people have been putting them in the 560's, and being how IH didn't really ever change too much, I think it is possible.

Today's Featured Article - Show Coverage: Fair Weather Tractor - by Dave M.. No, Fair Weather isn't some rare brand. It's the kind you can't leave out in the rain. Here's how it happened. I had been casually looking for a tractor for weeks. I saw a few 9N's, but they had even fewer amenities than the 8N my Grandpa bought new in '52 with a Dearborn loader. That was 10 years before I was born, so I grew up thinking that 8N was the world's best tractor. Grandpa had greenhouses, with over half an acre under glass, and that 8N did almost everything. It was the only ... [Read Article]
