Big Rigs Talk about other Cummins powered vehicles here. As a matter of fact, it doesn't even have to be Cummins, but it will be diesel! :)

Not a chance. the 855/N14/ISX family was born from the N/A NHC-250 small cam Cummins. you can find them in military and trucks from the 60s.

The Series 60 is all Detroit. Just as the new 2010+ DD15 lineup is all Detroit R&D.

If they don't leak, there's no oil left in them. Oh, and they make noise. LOTS of noise. Power, not so much. Kinda ruined my opinion of ANYTHING with the Detroit name on it, 4 cycle or not. I've never had major trouble with anything that Cummins made, not even the old 335's that were known for bending crank shafts. I have a Cat now, my first. I've had Cat's in equipment, but never road vehicles. We'll see how it pans out.

We have 1 ladder truck with a 475hp 8v02 in it, 4 pumps with 500hp 8v92's in them, everything else is either a Series 60 or a Cat. The v8 pumps accelerate like a car on an incline or flatland makes no difference. The biggest reason you used to find the Detroit 2 strokes in fire apparatus was not for propulsion power but for their ability to work while standing, something a Cummins was never really good for until the advent of the N14.

Personally Scott, I think the Series 60 Detroit engines were the cream of the crop. I have had no experience with them since Mercedes took over.

Was that a shot? I think that was a shot! And well executed at that!

Point well taken and I agree 150%.

Well, the reason WE, (Merrimac), have ever had DD 2 strokes is because they 'sound good'. We actually have a Series 40, 4 cylinder, 4 stroke, 350 HP in our newest pump. It's... 'ok' I guess. It doesn't seem like it's 350 horse, but it's been reliable. But it still leaks! Not as much as the 8/92 in the tower, but still...
You should have seen the look on my chief's face when he first heard it and was told they don't make 2 strokes anymore. Priceless! It was the only reason he ordered it with the DD!

Maybe it's a Series 50 then. The thing is HUGE!

The Chief, who else? God forbid anyone else have an idea that might actually work better or make sense.

The best thing about 2stroke DD's is that they don't rust. They are externally lubricated. They have been used in various forms in the oil field for years. There are lots of firepumps using DD's. One of the reasons being that they spin over easier than a lot of 4 strokes. They will run very loudly for a long time if you keep a steady supply of fuel and oil to them. We use a lot of Cat 3500 and 3600 series now and they require much more maintenance than the old V-92 engines we used to run. Most of it is due to corrosion.

Detroit was losing market share with the old 53,71 and 92 series. Cummins and Cat was coming on strong with new developments and pollution crap was just beginning.to be taken seriously by mfg.'s When I was at Wyoming Tech in 86/87 we got to crawl around on a Int 4300 with new 60 series engine. Truck hauled logs and the owner could not remove smile from his face...get my drift? Any who.... Ken sounds like you might have a plan that could work! Will this thing go down your driveway???? lolol

I was a tech writer for Komatsu-Dresser in Peoria,IL. and we built large off road mining trucks. We built 6 trucks for coal mine in Russia and they wanted a V-20 so we took two DD V-8 blocks and sandwiched a DD V-4 in the middle. Pretty wild looking set up and it sounded wicked. Don't know what happened because I was laid off shortly after we built the trucks. These were our electric line of trucks. Had individual wheel motors getting power from an on board generator. Hahaha! I just realized they were the first completely electric powered truck ever built....how bout that!! They were controlled by a computer.
