How long has the 6bt engine design been around?

[Jff24Gordn]

As bad as this is, the 359 I 6 design of Cummins/CDC/Case was borrowed from another company. Did you know that John Deere has a 359 I6 that is like our engine. It has a bigger bottem end, diffrent oil cooler setup, and a few other odds and ends. The spacing on the bearings, length, heigh, bore, stroke, casting shape of the block, and alot of other things in common. The John Deere store in Columbus, IN (which is no longer there) used to have a few 359's in the back that were parts engines. The story behind them is Cummins bought them, had them for a while, returned them, and then the store used tham as parts. At the same time, the Cummins/CDC/Case 359 came out. John Deere only used their 359 for a model or two till they stroked it out to 5".

Good Luck finding out who originally designed it. I personally make a distinction between actually designing something and just marketing it. Maybe Cummins did both... . or maybe not.



I agree with everyone else, this is a good thread.

Next Question...

... what is the fifth amendment?

Well, whoever designed it, stole the design, or decided to put it in a pick-up, I'm glad they did Chris

From Fritz's Ram Tech



The Cummins B series (3. 9L 4 cylinder and 5. 9L six cylinder) diesel was developed in the early 1980's as a joint venture between Cummins and Case tractor. Cummins was to provide the engine expertise, Case the production volume. In 1984, an active step van/ bread truck repower program for the Ford E350 and GM P30 chassis was successfully promoted by Cummins.



As B production capacity expanded, Cummins began actively seeking a major OEM entry for the 6B 5. 9L engine in a pickup truck chassis. The 6B was seen by Dodge as a possibility for the aging Ram 250 and 350 which had no diesel option. In late 1986, Dodge and Cummins reached an agreement to target the 1998 model year for the ram diesel. Cumins accepted the engineering challenge of mating the engine to the existing Dodge Ram chassis. As unseen technical problems surfaced, the introduction was rescheduled for the 1989 model.



The first year forecast was for less than 8,000 Dodge diesel pickups, with sales expected to grow by 3,000 trucks each following year. Ram diesel sales for 1989 surpassed 16,000 trucks and the numbers have continued to grow.



Cummins data indicates that the life of the B engine in a medium duty truck is slightly over 300,000 miles. Estimated engine life in the pickup is unknown because few engines have failed or worn out, and there are numerous reports of over 800,000 miles.
