That Rubi is impressive. Wonder how many rpms it saw and for how long before it let go?

Keeping I.T. real
I saw an RV leave a detailing place and the car behind it had the wheels turned to full lock to one side. It left some impressive skid marks and smoke until someone managed to flag them down and stop it. 🤣

that's, well, huh
Think about the stress on the other shafts, u joints, drive shaft, R&P. I am surprised the pinions weren't free spinning first, and then heat build up blew the rest? I want to buy that right now, in its current state. its a candidate for a family wheeler.

If the rv hit 60mph, that engine would need to spin over 50k rpm.

That is impressive. When did Jeep learn about 4-valve cylinder heads? I thought they were still feeling out the waters on the whole "OHV" trend.
Meh, Jeep had a OHC inline 6 in the early '60s.

Not sure how you came up with 50k?
My math with a 1st gear of 5.13, t case of 4.0, diffs 4.10 and say a 33" tires is around 13,000rpm

60 MPH tires are turning roughly 600RPM
600 x 4.1 axle ratio x 4:1 t-case ratio x 5.13 first gear ratio is 50,549 RPM
That engine let go long before 60 MPH

You and Boons both belong in the fail thread. The mph section of the grimm calculator is a 1:1 high range unless you 'enter own numbers' and put 4.0 in for the high range ratio putting you in the 50k rpm range.

Quoted for truth. It's almost like they have never driven a vehicle in 4 low in first gear.
"Yeah, Braw, 13k in 1st, 4 low, I was doing 70mph, and I got 26 miles per gallon".

Dammit!! I just spent 15 minutes on the Grimm calculator trying to figure out why the RPM’s were so low in the picture you posted and what I was calculating wrong before I bothered to read any further replies.

COOL!
It's not very often that the rope gear is needed on a rescue.
If the people in the truck were conscious, that had to be horrifically stressful.

What do you think caused that?
Big wind gust while crossing that bridge sent the trailer swaying badly?
It was a Willys designed engine, and there was a reason it was only run for 3 years here

Chronically stupid
So OHV is a just a recent trend or did you misstype OHC?
It was a jab at how archaic Chrysler engine technology generally is.

No shit right? A couple of hundred bucks and my 2005 cummins is current with the tech offered on the base 2021 cummins. I'm missing, tow mirrors, touch screen dash and a backup camera.
