German or International engine

We have a 1256 IH tractor. We were wondering how to tell if the engine is German-made or International made it... Any ideas?

German engines , were in my opinion , ahead of American engines during these times . I think germans had been using alternate fuels longer and had more experience.
 
the 1256 was only available with the (IH,American made) DT407.Darn good engine!About the only IH tractors with the German diesels were the late 706,756 diesels(D310) and the 826 diesel(D358),and (Ithink,maybe) the 786(D358).A couple of the smaller 4 cylinder tractors of that era also had a german,but I'm not sure which ones.
 
As stated earlier, the "German" engines only came in certain models, and the 1256 is not one of them, unless someone transplanted one into the tractor. Stranger things have happened in 50 years, and it is very simple to install a German engine into a 1256 with the correct parts.

To identify your tractor's engine, look along the bottom of the head, on the block, for a machined flat spot where a bunch of letters and numbers are stamped INTO the block (not protruding from the casting). These should start with DT407 if I am not mistaken, if the tractor has a DT407 engine.

The D358 German diesel was also installed in 715 combines, the 886, and the 3088, among other tractors.

The Neuss diesels were the first direct injected wet sleeve diesel engines that IH had and were released in 1965 in Germany. They didn't show up in North America until 1967 in the 706 diesel. The 4 cyl version showed up in the 544 in 1968. Tractors like the 806, 1206, etc used dry sleeved diesels and were direct injected. IH did not have an American built direct injection wet sleeve engine until the 400 series arrived in 1971. The direct injected American diesels were made in Melrose Park.
 
I'm pretty sure the 886 and 3088 used the newer American d360.I'm thinking the 786 also used the 360,not the D358 german. The 715 combine did use the D358,or was it the 310? IH used a lot of different engines....No wonder we are all confused! LOL
 

The "German" engines were built by IH, in Neuss Germany.

They powered almost every IH tractor built in Europe, including larger stuff we didn't here like the 1455.
 
The 886 and 686, both the first 2 yrs used the D360 and D312 respectively and the last 2 yrs they used the 358 and 310 germans. I have had both I have a 886 now that came with the 360 and the last one I had had the 358. My 686 has the 310 in it.
 
I have been asked which I thought was the best. Can't really give an answer. I have had both american and german engines and had good luck with both. I personly think the american diesels start a little better in cold weather. That's only an opinion. They are both good engines. One of the best cold weather starters I have had was a 706 with the 282. When I had it it wasn't very old. That probably helped. I also have a couple of JD 4020's they are good tractors, but don't like cold weather. My 766 diesel and JD 2440 start fairly well when it's cold. Of course my JD 2510 gas starts anytime.
 
My 1256,and 1456 each have the DT407. my (late)706 and 826 each have the 310german,and the 358 german,respectivly.These two (german)engines also look identical th each other.Early 706 used the D282. The 'old' D/DT 361(806/1206) look identical to the D(856)/DT407.After some time around these tractors,you will also be able to identify differences in different tractors. Happy tractoring!
 
No! Early 886's had the Melrose D-360 but about 1978 they switched to the Nuess D-358. ALL 786's had a lower hp D-358. And all 3088 & 3288 used the Nuess D-358. I'll give you ONE GUESS who started the idea of getting generic tuned engines from Nuess, meaning not tuned to either 786 or 886 performance specs, and sending them to our local Bosch injection shop across town to have final tuning of the injection pump done before the engine was installed in a tractor. That allowed the plant to change the product mix between 786/886 and 3088/3288 to better meet demand on the tractors. When the 786 first went into production they sold WAY more than marketing projected.

Melrose was struggling to keep up with demand of the 300 & 400 series engines. Construction, combines, tractors, and trucks were all going Gang Busters.
 
The 84-series utility tractors were all Nuess powered. The tractors were shipped from Doncaster as skidded units to Louisville and completed. Wheels & tires installed, ROPS, cabs, loaders, etc.
The little compact tractors were shipped as a knocked-down unit, some assembly required, but complete, a dealer could assemble it, didn't require any additional parts.
 
I think the AD-264 Diesel engine used in AW-7 Diesel tractors was direct injection from 1957. Same engine (I think) was used in the Super AMD tractors here in Australia. Not sure about British-built tractors.

The 1256 should have a DT-407. The oil filters should be 2 canister filters on the left side. The german diesels in the Farmall tractors used a single oil filter horizontally mounted just above the frame rail. The Melrose Park (300-400 series)engines will have 2 oil filters on the right side at the back of the engine mounted upside down and angled out towards the top.
