Which old engines??

The article spells it out. The deal never happened. Still many believe the series 60 was developed by JD. Penske already had a Business relationship with GM, having already bought their ACC in house Trucking Division. The Big 3 spun off a lot of divisions. It’s interesting how many things are manufactured by one and used on another. I’ve hauled brake caliper castings from GMs Saginaw gear. to Chrysler for instance. Good article, I just recently read that myself. Never knew the real story.

 

You 60 series Detroit fans should be upset for not of having the opportunity the V8 that Deere designed during the same time period the 60 series was on the drawing board.. All those bragging rights you were denied the opportunity to try to kick sand in our faces for those of us that have enjoyed the 3408 Cat experience... What a shame Deere didn't share that unique motor with Detroit

 

I have had the discomfort of working on several of these Deere/Detroit 12.5 liter heaps that was in the 9400 articulated 4WD. They have a 1 piece cover like a drip trout. But the similarities to CAT were much closer. You had timing pins to get the cam and crank in time. Canister fuel filter that was sheet. The cups come out of the head and went back in like a CAT. They were also 425HP. I am not disputing who was involved in what I’m merely saying they didn’t take much from Detroit other than looks at a glance. The overhead didn’t use companion cylinder nor over lap to set, however the injector height gauge was a DDEC copy. As was the lift pump. If it was a pan tractor we were in the engine majorly at low hours. They did get better though and were never the kinda junk @Catmando spoke of that was in the 8850. Those were the 2 that gave the most engine trouble

 

I'm about to make an offer on two trucks with Cummins 855s; neither are running, so they'll make good rebuild projects.

One is a 1982 KW K100C; the engine code on the door jam says TC 350. I thought it should read NTC 350, but I swear there's no N. It's been sitting in the corner of a hay field for years with the window down, so it needs a head-to-toe restoration.

The other is a 1981 KW W900 daycab; engine code is NTC 350. It has some more numbers after it but I don't remember what they are...something like 1800F.

Both have 9 speeds that I hope I can convert to 13.

An older mechanic told me he was having a hard time getting parts for the 855 engines, but a google search turned up a whole slew of places that sell stuff for them. The injection pumps are what concern me. I don't know if they need rebuilt or repaired, and I'm afraid it'll be a steep learning curve trying to figure them out.

 

I don't know much about Cummins, but I though the 855 was a V8 and the NTC 350 was a straight six.

I'll follow along to be corrected.

 

I know the 903 was a V8... the guys I knew that had em in articulating tractors always referred to them as nine o nothings

 

Maybe that's what I was thinking of.

 

855 was the cubic inch displacement of the inline six.

 

NH was 743ci.

 

I heard about JD’s involvement a long time ago. But the timing of a few other things going on when that engine was introduced kind of make me think there were others involved. I always thought the overhead cam and electronic control kind of pointed at Penske more than the green tractor guys.
