I never did save the comparison picture of the connecting rods to my hard drive. Does anybody have it or a link to it?

Thanks

 

DieselDaze has it in his photo gallery.

 

Thank ya suh.

 

Oh, I don't know... The Ford's are kind of dainty. Sort of cute....
Nice touch with the 12 point nuts though.

 

www.FordCummins.com has it on their page too.

 

You have to keep in mind that there are 8 cylinders in a Ford and a Chevy...

 

Yes...But...

8 divided by six is 1.33. I think its fair to say that the Cummins rod is much larger and stronger than 1.33x the competition.

Keep in mind also that the 7.3l PSD is 1.24x as large as a cummins and the DM is 1.12x as large.

On a more technical level, I believe the Cummins rods show a more mature design. For example, the Cummins rods exhibit the following characteristics that are minimal or absent from the GM and International rod:

1. Larger bearing surface area.
2. Better fillet radii to prevent stress concentrations
3. Maximum size of the crank pin, as evidenced by the canted end cap (required to remove the rod from the block through the piston hole, I believe).
4. Maximum size of wrist pin.
5. Nonlinear radius of curvature on the upper edge of the crankpin.

The above was written by TDR members rbattelle & DPelletier.

 

HeHeHe! That picture I took is sure making the rounds!

 

I should have snapped a pic of the 6.0, Dmax, and new Cummins rods at the rodeo. Oh well. They were there last year and this year, probably be here next year as well.
