I have an n7 engine setting in the shop floor ready to go.... Came out of combine that caught fire. min damage to rh side of engine.. we replaced all the rubber stuff, used a rebuilt starter we had in stock, used inj pump from another salavage machine, reman turbo installed. and i think all the injectors were rebulit or at least tested, has new return line. Engine is setting in frame ready to go.. We ran the engine and checked oil pressure and it cecked out ok.. Has been sitting shop since 1998... email me if interested or nee more info.......

The 516cid_685 engine is a little different than the 2 smaller engines, more comparable to the 731cid in configuration in the 8550_4W-305. Also the parts may be harder to find as 685 was only used in the N_R7 Gleaner and HD11 Crawlers. They do have Cummins retrofits that work great, the 8.3_C 505cid Cummins or larger. Just make sure that the 270hp requirements are met.

Who sells these retrofitsIJ Do I contact CumminsIJ I heard that someone was installing Detroits on these combines. Thanks for your reply but I am confused. Is the 8.3_C and the 505cid the same motorIJ

Yes the cummins 8.3 ans 505 are the same engine,,but,, there are at least three horspowers of it.......

The Cummins dealer in our area knows who does the retrofit. They do it for the combines and 70 and 80 series tractors and the 4wd tractors. And yes the 505cid is the 8.3C engine. I'm not sure if it will hold enough torque, might want to check out the next size larger. 270-330 HP is a must with the N7.
