COE 5 ton frame

A friend is looking at putting a newer 5 ton frame under his international COE. Detroit diesel to be installed out back weighs around 5000#.
Some issues:
Track width- fix with widened fenders.
Centerline of front wheels to front of frame won't fit under cab- move steering box back, wack off frame.
I am sure there will be more. Anyone use something this heavy? Thoughts/ideas?

 

geez ADAM !!! How Big Is THAT goin' get ? said Eve.

 

5,000 sounds sounds like a 12v71 or 92, (along with a trans) making a COE version of the Pissed Off Pete?
A 5 ton frame is basically a cl*** 8 semi tractor.
I used the frame from this thing, had a GVW of 27,500. frame is a 3x9x5/16" channel. I whacked the frame off where I needed to and added a semi-cross steer set-up using the original steering box hooked to the Dodge dually steering linkage. BTW this is a IH ch***is with a 6v53T Detroit

 

At least its been done before (relief). Yes I do believe it is a 12V71. The front leafs will have to go also as they are attached to the front of the frame. Would you have any pictures of your front suspension?

 

Hope you can decipher my photography.
This is the Dodge axle with stock locating links fastened to a frame mount I built to locate the axle the same as it was in the stock pick-up. I converted to air ride by making a lower bag mount that sits in the stock spring location and a custom piece for the upper bag mounts.
This is the stock IH steering box turned at an angle so the pitman arm swings in the same plane as the rod (forgot its correct name) to the spindle steering arm. Everything except the pitman arm is stock Dodge. Pitman arm is a shortened IH part.

 

Thank you very much. I am hoping to keep the 5 ton I beam. But may incorporate similar to yours 4 bar.

 

Look at the various straight axle set-ups on the more traditional rods. Hairpins are pretty simple, yours will just be a lot heavier duty. There are tons of threads on the main forums that can help you think through it.
This one looks like a spread wishbone set-up on the front and hairpins on the back. BTW the Detroit is a lot bigger!
