The canted rod is also weaker.
Steel Soldiers now has a few new forums, read more about it at: New Munitions Forums!
where dose this info come from? whats the fail rate of the 5.9 cummins rod? same cap design......The canted rod is also weaker.

I do not know the spec on the 465 but on a 6bt the rod would NOT fit in the cylinder if the traditional rod design was used. There for the canted design is nessesary for assembly. It sounded like you where refering to the crank case walls. correct me if i am wrong.The big end is canted like that for a couple of reasons. To allow for the largest possible big end bearing and to keep the dimensions of the block casting as narrow as possible. Nothing to do with ease of maintenence.
Well, I can't personally argue either way; only relay what I have read. Taylor's book was clear in that the ONLY reason to cant the rod cap is to facilitate rod removal through the bore for a relatively large bearing diameter. That other engine mfg use a canted rod doesn't mean that it wasn't a compromise. If it were stronger, everyone would be using it. I strongly suggest that anyone interested in ICE design get a copy of Taylor's comprehensive two book set. It has a small section on multifuel engine design, too.That is incorrect. Most all of the modern HHP diesels have canteed rods and they are fracture split. Not just HHP, little 3.3L engines are like that too.
Dave,could you share this info? where is it weaker? Dose it produce a problem in the beam? (the ld's week knee) or is it refering to the journal and how the bearing rests in it? Or to the fact that bolts must be used?
