Required Rod Bolt Tension
(OP)
I am trying to determine the required tension of a connecting rod bolt in an industrial application.

RE: Required Rod Bolt Tension
Be sure to consider bearing crush in your calculation, as well as inertia loads (of course). I like to use the entire thickness and width of the steel backing, plus 1/2 the thickness of the bearing lining, in this part of the calculation. A typical bearing hoop crush stress figure would be in the neighborhood of 215 MPa.
It is also nice to compare the washer face stress to the yield strength of the conrod material, to make sure you aren't going to smoosh it too badly when you torque down your bolts.

Thanks for the link to www.boltscience.com
I have been trying to get real info on comparitive bolt strength vs size for rod bolts for the Little Giant.
I am makeing a pair of rods for her with much more compact bigends, useing a 4 bolt design, instead of the original hinged design. I am trying to keep the distance from the journal to the outside of the bolt head as close as possible, so I can maximise the stroke. Yes I am makeing a crank and pistons also, and useing a modern oil system and bearings. All hiden inside the crankcase and cam box.

Pull up their website.
Pat, I just had to do a brake job on the front of my Model A and I am still stuck in the 30's . It may take a week to get back.
If I had you email I'd send you a photo. Of the CAR, not me!

If you like I can return the favor for several cars and boats, the most interesting being:-
The 1913 Little Giant
A late 70's British Ford Capri with blown, alky, injected SBC, running 9.02 at 154 mph, with a lot of development left.
A 1970 timber, clinker built ski boat.
