injector difference between 1175 and 2470

DC3puller · Feb 7, 2015

Was looking in Abiline Machine at injectors and they sell the same one for 770 thru 2470. We ar going to pull an 1175 and did not know if there was a difference and difference in the fuel pumps thanks

I believe all the 70 series take the same pencil injectors.

The 1570, 2670 have big nut injectors and the big cranks. for the most part all the 451 s and the small crank 504s use the pencil.

There are diesel shops across the country that can rebuild your pencil injectors for pulling.

The parts book shows the same injector for 770,970,1070,1170,1175 and 1270,the 870 is buy its self and the 1370 and 2470 are different,I think it has to do with the spray angle for the larger bore motors.If your going tractor pulling put an add on pulloff for a set with larger holes in them,then you can make smoke have fun and buy more parts.

As far as pumps yes there are differences in plunger size. Your 1175 will have a 9mm pump. The 1370 2470 2090 2290 and some 2390s had 9.5mm pumps. The biggest pumps were on the 1570 2670 2590 4690 and some 2390s and were 10mm. Not all the 10mm pumps are the same some will put out more fuel than the others. Injectors all new replacements are the same for all engines with pencil injectors. Good luck

That's what I didn't know . Wondered if the different tractors had bigger or more holes and the different cc's the pumps put out. We have put a 3lm charger on and are planning to run 8mph classes thanks
