Searched and found conflicting info, can someone clear this up for me I have very limited interaction with the 6.7:

Does the 6.7 use the modular bellhousing pattern such as the 6.0 and 6.4?

There are several threads online where people claim it as the SAE bolt pattern.

Thanks.

 

No. Nor do the 6.0L/6.4L engines for that matter. What they do use however, are various different rear engine covers that enable them to be bolted up to many different transmissions including but not limited to Ford's 5R110W, ZF-6, Allison and Spicer transmissions for medium duty applications.

As you can see, the pattern on this engine is circular shaped, nothing even remotely close to the seven bolt bellhousing pattern used by the 4.6/5.4/6.8 and 5.0/6.2 gas engines

 

boobies....lol

 

I see, thank you. I guess my next question then is what is stopping someone from hookin up a manual to the 6.7? Just the engine electronics?

 

That, and the lack of existence of a manual transmission that could possibly withstand the power and torque output of a 6.7L. Remember the 6.0/6.4L engines' peak torque is 570 ft-lbs. The 6.7L puts out between 800 to 860 ft-lbs. of torque. That's a huge difference. Even if one were successful at fabricating an adapter plate to enable installation of the existing ZF-6 behind this engine, I highly doubt it would live very long, never mind the engine electronics issue that would have to be overcome, to make it happen.

Believe it or not, the Ford Workshop Manual does have service procedures for a manual transmission for the 2011 to 2016 (and even 2017) Super Duty trucks. However, it's not a six speed manual. Only a five speed, and I believe sold only on trucks in the South Americas and only with the 6.2L gas engine.

 

Thanks for the information.

What about the 6.7 used in "medium duty" applications. Do they all have a Ford transmission behind them? Like you mentioned earlier, usually EATON would have a manual trans that would fit the bill.

Also on the engine electronics, has anyone successfully transplanted a 6.7 into another project and built their own wiring harness yet?

Thanks.

 

Ya your right on the 6.2 V8 and 5 speed, this is right off of Ford Mexico website. Very interesting. Only comes in the F350, the Mexican 450 and 550 you get the 6.8 or 6.7.

 

Lead foot diesel in Monroe Ga has a 6.7 with a zf6 behind it. Pretty sure it's a 2.5 class pulling truck. It can be done with time and money. How long that zf will live, who knows. They are tough units but even the a stock 6.7 is past the designed input torque rating. They must have a decent service factor incorporated into the design which is likely more than 2.5 times the torque rating being they are still holding up to some of these tuned trucks.

 

Do you have a website link to this? I, for one would be very interested in seeing the quality of the swap done.

They have another video on their Facebook page also. I've heard nothing but great things about this shop so far. I'll find out in a few weeks when I stop by to start deleting mine.

 

Awesome! Glad to see somebody did the swap. I am going to contact them for more info.
