The rim size & shape is not the problem: it's still correct at 16.5x8.25, with a 15° shoulder. It's the other things you said, that matter.

Before anything I would put the correct 12-bolt wheels in place... Safety first!

OK, so I edited my drawing, accordingly. (updated my previous post #15)

The shape of the top of pad is not conical but spherical, machined to a certain radius. I put your dimensions into a drawing (PDF, all to scale) and found that said radius is more like 5.0" To confirm it you could compare the contours of the pad with a Ø10" disc as background, and see if they...

Height of the "lip"? (should be ~ 0.28") Radius of the dome? (should be ~ 5.5") I take it that the total height is 1.05" in the center and 0.905" at the edge? Please measure to confirm. Thanks!

Yeah, maybe even more than 4, if we included the many different stud hole designs in each case. But since the OP's question was about "same lug spacing"..., my answer was two - which of course means NO, not the same for all (20") wheels.

Military or not, for truck wheels 20" and up, there are only two different patterns (= pitch circle diameter) in use, out there: 10 on 335mm and 10 on 285.75mm (= 11-1/4"). First one is the most popular, by far. I'd say it's 99% of all big size trucks in the world. So the other dimension would...

Next time anyone needs a NIB correct (diesel) TC for the TH400 (for a fraction of that cost) @gimpyrobb still has some at his place. (And once he runs out of stock I know where to find dozens more...)

This thread will tell you what to use... Ha... one of those things we only do once...

Some of those are loose and fall out when you remove the bracket; others are a tight fit, and then some are like solid, welded in place... But that's only from rust built up. So don't be shy and just use a bigger punch and heavier hammer, with the bracket firmly supported. PB-blaster; Rust-Off...

Looked up TM 9-2320-209-20P, Oct 1976, found in Fig.108, Item #28: NSN 3120-00-661-9035 Bearing, sleeve Googled above NSN -> https://www.iso-group.com/NSN/3120-00-661-9035 I still have some NOS bearing sleeves stored somewhere, so I could measure them to confirm above specs - if I can find...

Yes, absolutely! Problem with two short ones is what keeps them from sliding out from under the bearing, towards the center of that spring seat. (?)

Thanks for that contribution! First time ever I get to see a full keyway there; just as it's supposed to be! Interestingly, the part number remained the same. So, what about the key(s) itself? Guess it should be one only and full length, accordingly. Certainly, not just two of the short ones...

Correct. Red line for rpms is there for a reason; to keep things on the safe side. If you wanted to go higher for extended periods, rebuild the engine and do something the military doesn't care about, that much: have every rotating part perfectly balanced! Actually, that goes for every engine...

Sure, but that would be more like momentary contacts only, at low speed (<15mph). And it is clear that with extreme low TP the increased flexing work alone will create a lot of heat in the tires. Not exactly what I was referring to as "normal use". What I have yet to confirm is what you have...

https://www.hummerpartsguy.com/LUBRICANT-RUNFLAT-1-TUBE_p_24187.html 1 tube per tire should be sufficient, if you manage to apply an even, 4-in wide bead to the crown.

It should be noted that the runflat inserts (all versions) are always much smaller in diameter than the inner tire. So, for the 395s and 14.00s it takes about 5" for the tire to actually touch the RF, so that would only occur after much deflation, e.g. during emergency use; or a mayor air leak...

Yeah, for what it matters, the top covers are identical for both models. So, yours wasn't really stuck, or...?

TM -34 on p. 3-17 reads: (3) Place the interlock plate into position and install the springs and plate spring washers. Plate spring washers are installed between the springs and the shifter shaft cover. That would be all 3 stacked together on one end. But since I don't like how the spring is...
