Picture of crank

Great pictures Bob, I knew the Cummins was made of sturdy stuff but this proves it!

 

[John Berger]

Good pics Bob. I have a question. Why is the bearing cap offset on the Cummins rod?

A picture is worth 1,000 words

Thanks Gene and Bob! These pictures ought to settle any arguments.

Good job Big Bob. You came through. I think I'll wait till Monday when them other ford buys are back at work to show them. That should start there Monday off right.

Big Bob's photo's clearly show which is the Heavy Duty Diesel of the bunch!



Great Photo's Bob.

The angle of the rod cap never allows the force of the driving pistons to be in-line with the bolts that hold them together. I'd have to do a stress and shear analysis, but I'm lazy today and it sounds good anyway.

Main Journals?

Big Bob, thanks for the cool shots



What about Main Bearing Journal diameters?? I'll bet the others are a little smaller than the huge 3. 3" diameter of the Cummins' main bearings

My goodness Man, Are you sure that Lucas isn't involved with some sort of CGI Photo tampering with these pics?



Will start printing immediately as the public has the right to know!!



Must note to add copies of illustrations posted on PSD's already.



Got it!!



Boy are they Mad!! Even the 6. 2 Chevy dwarfs them

Those guys don't have a sense of humor. There was an outstanding post over there a year or so ago on the Cummins engine by one of the moderators. I'm going to try to find it. Very interesting read. I also like what Jason Lester, the owner of the website said once. I'm paraphrasing here: "You look at both trucks, pick the one you like the best and rag your buddy for buying the other one. " Well put.





Here it is. The topic is cavitation.

In what years did GMC/ Chevy have a Detroit? Surely not that 6. 2 POS.

The offset means the rod bolts are not parallel to the forces acting on the rod, reducing chance of stretch. This means that the rod bolts rely on their shear (crosses the shaft of the bolt) strength, which is never in the same direction for very long, as the crankload goes through a full circle.



Interesting note, the Ford Triton engines have a one piece powdered metal rod that is drilled as one piece and "fractured" to produce a rod and cap.
