806 diesel

[Robert Nighswander]

Iam looking for reasonably priced replacement injectors for my 806D. I have found many injectors priced right for a 1206 and would like to know if they will fit the 806? My tractor has a M&W turbo kit on it so a litte more fuel would not be a problem. I would really rather stick to 806 injectors as I only use the tractor for light duty work. Spraying or moving wagons..

806, 1206, 856. 1256, 1456 all use the same injectors. The amount of fuel is delivered from the the injector pump setting.

Physically the injectors are the same size and will interchange but......each tractor/engine have different oriffice sizes and springs. I do know that a 806 has a .047 opening and a 1206 uses a .050 oriffice. I don't know what the difference in springs are. I don't want to use the 1206 injectors that are available everywhere on the internet at a reasonable cost because they are a (bigger) injector. I don't pull anything hard with this tractor and don't need the extra HP or higher fuel comsumption.

Actually there are several different injectors for that series of engines, some use a larger spray hole in tip and like said the sac hole inside tip. The natural asp engines went to a five hole tip, don't think the turboed engines ever did. Also, the hole size in the injection lines was changed during the 56 series, back from .080 to .062 like original and then the delivery valve in inj pump has to match the lines and the tips on the injectors. So, like I said, lot of different combinations and years ago it was not uncommon to find them mixed up and I am sure it has only gotten worse .

Thanks for the information! I am going to pull one of the injectors out of the 806 soon and get some part numbers. The injectors in it have worked fine for 30 years. I'm still looking for some kind of replacemets though so advice is welcome. Go Red!!
