Old 6.2L GM military truck ... Talk me out of this......

Square body diesel?!? I’m jealous.

Who cares if it’s slow or doesn’t have much power.

Seems like a lot of money, but the low mileage, good bad or otherwise, helps to justify it.

If you can afford it, garage it (so you can put colllector insurance on it), then go have fun!!

Really good advice. Collector insurance companies are really good and fair in my years of experience. They actually will cover many vehicles lots of folks would not expect them to. They will also sell a person no deductible policies if one is inclined (I would advise)
to do so and not expensive. I had a one car accident in my last Chevelle that required six months in shop and the bill was just under
$6000 and it was zero out of my pocket. What a relief when one is already under the strain of having one of your fun machines damaged and in need of serious repair. (y)

I put Hagerty for 10k, to cover the cost of purchase and some work I will have to do, everything else will be on me.

It is in good shape for an M1008 Most of them lived outside in the rain. This one did not.

I plan on fixing what needs do be (not much or unknown) and just driving it around town. Really wanted one for a long time, and as time goes by, they will just get more scarce.

It is a fully manual 4wd, meaning locking hubs and manual shift. the 1986 model had a chain driven 4wd as opposed to the NP205 which was gear driven. I would prefer the 205, but the 208 is pretty tough also.

I will use it sparingly, keep up with it, and see what happens.

It is a torquey thing.

I am sure from the looks of it and the way it was built from the factory + maybe modified for Uncle Sam use it will lead to much
enjoyment. I really would not expect and hope you do not end up doing much wrench work on it unless it is something you want
to change for your own special needs. I have always looked at motor vehicles as two categories. #1 Need of transportation. #2 Need
of FUN! ;)

I agree. Vehicle are the most important things we have as lowly humans.

I will have to address the PS pump leak, but the rest is regular "things you should do when you buy a new ride"

Is the truck 12 or 24 volt?

The only thing that is 24 volt is the starter, and a portion of the glow plug system, but I am going to change that pretty soon. It is common misconception that the whole truck is 24 volt.

It does have, different from the civilian truck, 2 separate jumping and \or power ports for NATO requirements. Both I will likely delete for simplicity.
 
Update, changed the pump today. First PS pump I have ever had the privilege to change. What a pain.

The pressure line was visibly new, but I did replace the two return lines with fuel injection hoses with some nice clamps.

Next is to drain all the fluids, and replace them, and do some minor electrical surgery (little nit picky things, I am pretty electrically nit picky). Will post pics later.

I am thinking on deleting the factory stater relay with a common lawnmower style, and deleting a knowm failure point (becuase it was an internationally used vehicle), which entails removing two resistors which change the voltage to the glow plugs from 24 to 12.

In military style, about 1000 pages, good info though.

There is an oil sampling port, cool

That's bizzare, I assume there are some chunky relays that rearrange how the batteries work between starting and running/ charging.

No not really. There are some resistors, but are removable.

There are 2 12 volt alternators that charge the batteries, nothing really out of the ordinary, other than a few things.

Batteries are in series, again nothing special
 
Nice ride! A lot of it is standard square body, but the M1008 has some extra coolness factor to it. The Dana 60 front, and the rear 14 bolt (it should have a Detroit Locker in it, if you've never run one when it goes BAM real loud, it's working normally!) are tough as hell, you won't break them. While I was reading the post I was screaming 205 or 208?... lol... you answered that later on.

Last one I owned had a blown up 6.2 when I bought it. A 454 sits nicely in it's place...lol.

Nice find!

208. WOW 5 quarts of fluid for it, astounding. Wish it was the 205, but the 208 seems to be good, or so the internet says.

454 in one of these would pull the gates of hell of the hinges, and whatever the hinges were connected to.
If the engine ever died, my choice would be a GEP 6.5, to keep it with no electronics for running, but a 454 would be killer. I lift and big tires would be in order then, 37s or so like the HMMWV.

Today I am continuing my work on it, deleting the 24 resistors and running new 12 to the glow plug relay, and remove the crapping statrter solenoid, and doing the "doghead" conversion with a lawnmower solenoid.

I did change the powers steering pump out with a re-maned from NAPA, but it seems like it needs to be bled. Will work on that later today.

The 208 is a good transfer case. You won't break it.
 
The 6.2 isn’t a bad motor, I know it’a gets a bad rap because it’s not a 7.3 PowerStroke or anything Cummins, but it does well. Only issue is that now parts are getting hard to get. I knew a guy who had an CUCV with an PTO drive and he used a Warn hydraulic winch no problem.
