Identify this style of drums and axle hubs

You're not wrong..........

 

Little stretch like that is something I’m considering with my K100C, for a couple reasons. Just don’t want it long as my W9 if I do though….,

 

That's sharp.

 

I don't claim to a expert on stretching .. but I've done a dozen or so in the last 30 or so years .. that 9670 I just did was the 3rd with tapper rails.. don't hold me to it but IH is the only trucks that I know that have tapper frame rails.. It takes alittle longer to get things aligned correctly.. but its doable.. there little tricks I've learned everytime I've done one..
You'r only good option as far as a cut off goes is a airliner it comes the closest to fitting correctly unless you find a good IH cut off which is hard to find ..
I also now have a good source to custom blend inserts for me which makes it alot easier
Them old Bs I think look kool with some extra yardage .. I would like to do a B someday just to say I did one Heres a couple pics of the 9670 .. don't judge me on the ugly ### wet kit crap .. that's exactly how the owner wanted it .. was not how I would of done it

 

I see some B's for sale quite ofter.. that wet kit on the 9670 I did ... he pulls a belt trailer .. I put the wet kit on it also

 

Problem is they are I-H proprietary Dana built. So that limits your options to only another I-H somewhere for parts or a nos supplier if there is one. Dana had so much stuff back then that didn’t interchange and I think it was because they were small time in the axle world but owned Spicer and were the #1 driveline supplier for everyone back then and were always building one offs to try new things to see if they’d take off and be the greatest new thing. Rockwell on the other hand came from Timken the inventor of the modern tapered cone style roller bearing and they had nothing to prove. They kept it simple and majority of their stuff was interchangeable for years.

 

International rear end ratios were oddball also. the 1977 in my profile pic had RA-355 rear ends with a 4:10 ratio. I drove a 1987 9670 Eagle that had a 3:91 ratio

 

Old retired friend of the family drove for Western oil field service co. (Been defunct since first Tejas oilfield bust in the mid 80’s., ether Schlumberger or BJ Hughes bought them out.) Anyway They had TransStar 2’s mixed with White Road Commodes. They all had 8v71’s, Rto12513’s. The I-H’s had 3.72’s when everyone else was 3.73. He always wondered if that made the one mph difference in top speed between the two.

 

I think the biggest problem @mile marker 27 would have if converting to hub pilots and outboard drums would be the brake spider location. Would it be to far inboard?
