Hear is the link to the new 6.7 http://www.construction-int.com/arti...515&artID=3126

" These enhancements include a new block with higher displacement, a new high-pressure common rail fuel system, a new electronic control module and a rear gear train configuration. Allied with Cummins advanced in-cylinder technology they allow the QSB engines to meet Tier 3 with significant performance enhancements. "


Rear gear train configuration, boy the diesel mechanics are going to love that.

Gear Poet

“The increased displacement means that the QSB’s can now be fitted in installations normally requiring engines with higher displacement. This provides equipment manufacturers with a much more cost effective power plant backed by the renowned reliability and durability associated with Cummins B engine platform.”

Wonder how tough it might be to fit the QSB to existing B engine platforms.... ? No dimensions given.

The current European 5.9L B-series Cummins has a rear gear train. It shouldn't be any harder keeping a front gear train on a 6.7L in a Dodge application than it is with the 5.9L.

I think you guys have only missed one thing... the 6.7 is a structural block ,meaning it is meant to be used as the front frame of a tractor...

I know signature 600 will back me up on this.

RustyJC

Yep, it is, but the heavy lifting insofar as design is concerned is already done. They can use the design work they've already done for the innards of a non-structural 6.7L. Remember, the 5.9L started out as a structural block engine as well.

I'm waiting for the small truck version of the QSM 11, 660 hp at the fly wheel.

The 4.5l would actually power one of our trucks just fine, with computer hacks of course!

All ISB in the meduim trucks are rear gear train not just the european versions, Dodge ISB is the only version at this point with the front gear train. we are doing a 6.7 truck engine install for field testing right now in a transit bus, just waiting for the harness and ECM cal from the factory. motor mounts are the same as the ISB N.G. engine removed from the bus which is no different from the Diesel ISB. should be running in a month or so , will let you all know how it runs.

not that big a deal. you need to do some work, just pull the engine or drop the trans..

[now on the engines i work on with rear geartrains, they are a pita, as if you want to change the drive and #1 idler gears, you need to remove the engine to do so... and ±10,000 CID of engine isn't the easiest to move]

JKM

That's what they do when the need to work on the gear train of a VT365 at work , drop the trans and get it from there.

Yep been there, In a ram pickup i might actually like it more? Never worked on one but seems that it would be easier to drop a trans than pull all the front end off. Autos would take longer but psh

Yes there is a 6.7L Structural block right now...but as far as I can tell, internally it's a stroked 5.9. There are A LOT of common parts.

Remember though...I'm just a dumb farmer with no clue about what's really going on at Cummins, so what do I know. We just used them in tractors, and don't use them anymore.

Well we just finish putting a Nonstructural Block 6.7 in a bus and run it on the dyno with a World trans behind it...... it is for field testing. it is also running a PM and nox reducing muffler filtering system, here is the cool part. the common rail system is set up for 2100 bar, we changed out the injectors , injector hard lines, rail press. relief valve and the CP3 pump to handle the 2100 bar. these lines are quite a bit bigger then the 5.9 ISB. and flow more fuel. the Nonstructural QSB is in limited production right now and going full time in January.... the rail system on the QSB is set for 1800 bar. gonna have to get me the common rail and relief valve and hard lines off one of them 2100 bar system.

HOHN

True, but imagine how HEAVY the structural version must be if you just dropped into a Dodge

Might need a Dana 80 up FRONT!
