Thanks

Yes sir. She is a M936. It is looking better all the time. Fix a little, play a little, replace a part or several, and play a little more. I still have plenty to do, but it was amazing what some wire brushing, rub-down with Acetone, then rattle can paint did for the outward appearance. My goal there was to make it look better and then this stupid virus showed up and everything got shutdown. Heck, just driving down the road a few miles and back home will get a half dozen hand waves
That isn't quite as exciting as a real parade, but I have had a few one truck parades!
Real big time CONGRATULATIONS on getting college paid for. That is a big deal and it takes persistence for sure! This will be great. Having a few bucks saved up and your wife being able to say yes is pretty fantastic. Especially if you can get her involved for a few short trips! Quite a few of the guys here have family involvement - kids and wives too. Trips to the grocery store or the local hardware will be a lot of fun.
The 5-Ton Multifuel is a tough old motor. The magic was (still is) its ability to burn just about anything for "go juice". Lots of the guys here run filtered used motor oil and gas. Gotta get the mixture right, but in past military struggles that ability to burn whatever was a big plus! It definitely is a diesel with an injector pump and injectors.

I was looking back about what to do for a truck that has been sitting for a while. First concern is looking in the fuel tank. If it has some, is it fairly clear? It isn't growing gunk? (regular pump diesel will do that) You will be looking maybe with a cheap inspection camera that plugs into a USB port lets you dig a little deeper. I have one that I found that claims to be waterproof. I have dipped it into the bottom of my fuel tanks for short periods of time... It will plug into my Android phone. Less than $40 delivered if I remember correctly. If you have dirt, rust or algae that needs to be fixed before you turn over the motor the first time. Another thing to consider is that sloshing fuel might loosen rust inside the tank. You might run fine, then quit running because the fuel filters get stopped up.
Everybody has an opinion about motor oil. It needs to be changed because the process of diesel combustion turns pretty golden oil black in a very few minutes. There are companies that will test your oil for contaminants (slivers of bearings etc) but I would pull the dipstick, make sure it is near the fill line and leave it along until it cranks, idles and will actually run for you. A piece of coat-hanger wire pushed in that dipstick hole - all the way to the bottom - then pulled gently back out could tell you if there is sludge in the bottom of the oil pan.
The gearboxes: manual transmission, transfer case, front and rear axles all use the same gear oil. The thing to remember is that oil floats on water. I don't really know the history of your truck. You might not either, but on all the gearboxes there is a fill hole and a drain plug. If you are going for a 5 mile ride, I would do more - but to start with - just open the fill plugs about halfway up the metal casting (normally a half inch ratchet fits those plugs). Stick your finger in there with it bent at the knuckle toward the bottom. You should touch gear oil. Do all of them. Then you know you won't burn up something...
Brakes: Yes, pulling the hubs is likely a good idea depending on how long it has been sitting. It should be done, but YOU have to have some amount of personal satisfaction as you work on this thing. I wouldn't rip into removing those tires and hubs until you can crank and run. You should be able to look for brake fluid in the master cylinder. I think there will be a brake booster in there too (not certain). I am a little fuzzy. Some have "air over hydraulic" and some do not. In any case if you step on the brakes and pump them a time or two - the peddle shouldn't go as far down on the second or third "pump". FOR SURE, don't throw it in gear and zip off down a hill
Battery Power: These trucks are 24 volt. Minimum of two batteries required. Maybe charge them up and see what happens? If you have a normal car charger, you can attach the battery clips to the Plus and Negative on one battery to charge it, then do the other one - and if you have a 4 battery set - same drill but more times. Might have to replace them, but maybe not.
So I don't over do it, digest a little of this and maybe we talk some more as we go along. Posting some pictures will get the folks here excited and me too! That will get the suggestions rolling in too... Heck, maybe if you know a little history about the truck and when it last was running might tell a lot about it too.
