The HMMWV should have plenty of azz to spin all 4 tires while pulling against something that won’t move.

Don’t turn the drums, they need all the thickness they can get. Whoever relined the shoes used too thick friction material.

I tend to prefer original, but even I plan to swap in a much newer GEP 6.5 and a 4L80E in mine. The steering box frame reinforcement and shackle flip make sense as well.

I usually sandblast it off but it’s super slow going, like 10 minutes per side. That carc is tuff stuff.

First picture is the hood anti-flyup catch that bolts to the front of the inner lip of the inside of the hood. The second is the spring catch that holds the hood shut.

It’s been my experience that the tax office people derive pleasure from sending you away without what you need, I think they get training by watching puppies getting tortured or something sick like that.

Here is the registration fee chart. Your GVW is 15220 plus 2.5 tons (5000 lbs)

Your tax office girls are clueless, go to a different office or ask for the supervisor. No reason you can't get truck registration at $205/yr.

Even as we speak, Navistar is casting 6.5 blocks for AM General for HMMWV engines so looks like the IH foundry has always been looking for side hustles. Makes sense, gotta pour steel around the clock, not like you heat up a blast furnace every morning.

I would disconnect and tape up the burnt cables and try to start on battery power alone. M1083A1s are not something I would part out just because of some burned wires. I think that may have happened at the gravel pit by someone that tried to slave start the truck that had no clue what he was...

Looks like a doorbell transformer. Those put out 24 volts, but it’s AC. Can’t use it to charge batteries. I personally would pitch it and install a new maintaner.

I am pretty sure all civilian 3/4 ton trucks and the M880 series all had Dana 60 rear axles. What I found out the hard way is that the wheel ends are different between 1976 and 1977.

Yes but check and double check you have the correct cable feeding the correct voltages! Get it wrong and expensive stuff goes poof.

You have a real 1976 M880 and a fake data plate LOL. Actually a good problem to have.

Be careful, those two cable lugs are not supposed to be bolted together I don't think, one is 12 volt and the other 24 volt feeds to the LBCD.

Is this 4 wheel drive? VINs that start with D are 2WD. If you have 4 wheel drive, then the VIN data plate is bogus and you have a 1976 truck.

Wow that is nice. Does the VIN on the data plate match the other VIN locations? Truck has a 1976 grille.

Data plate looks legitimate, I suspect you have a truck that the Navy bought after M880 production ended in 1978, and since it was equipped just like a M880, Chrysler stamped that on the data plate. M880s were 1.25 ton rated, even though they were 3/4 ton trucks in civilian trim.

Oh you would be amazed at the test requirements that each truck had to go though at Sealy. The QC guy told me there could be no drips or leaks of any type after the test course was run.

This video kinda justifies why the FMTVs came with the reduction hubs originally. I doubt the truck could climb those grades with 5000 lbs onboard and towing a loaded M1082 with ECOs.
