That makes sense as I think the C12 is about 40% larger displacement than the 8.3. The C12 is still not as big as the NHC250 in liters but I can see where 2 650cca batteries in series will struggle some on the crank. It's just a lot of displacement to compress on two small batts. And I'd say...

I know the military prefers over to have over 2,000 CCA available with their battery set up but I'm curious if there is any Cummins documentation on cranking amps needed for the M939 series. The reason is I'm looking at a getting a couple new Group 31 batteries and will need to determine if I...

I just found where I lifted the pic from my post #19- it's also from a post #19 in this thread: https://www.steelsoldiers.com/threads/m939a2-shifting-issues.213336/ Lots of good info that I used in building my troubleshooting Thanks @Elijah95

That's a good way to start the troubleshooting process. That also brought back some old, but fond, memories as a young kid helping out on the farm. The punishment for us kids running grandpa's tractor out of diesel was that he would loosen the injector lines at the IP and then he would hand us...

I'm not seeing a sensor in the TM (see attached) so not sure what you're referring to. Also, the pic of the motor is a pic I lifted from this forum and not the truck in question. I can't remember which thread I took it from so I can't give them credit. But I think you just gave me an idea...

The seller called me back and asked if I was still interested in the truck. I hope to take a look at it in the next week or so and want to be prepared in basic trouble shooting of the fuel supply system and IP. I still think (hope) it's something easily fixed... I've been reading up a lot on...

I hear ya but my cap is pretty hard to put on or take off. I even removed the screen section and it's still a bugger. When I tighten by hand, I'm pretty sure I'm not even bottoming out on the rubber gasket. Using a large set of pliers gets me another turn or two but I still don't think it's...

I need a new fuel cap for my M923. The little pot metal fillers in the four holes corroded to the point where they started leaking and falling out. The only reason I can think why they exist is that they would melt during a fire and allow pressure to escape the fuel tank so it doesn't explode...

When I was 'playing in the sandbox' in 2003, I remember transportation units asking the engineer units on our base to cut up shipping containers and then bolt/weld it on trucks and hummers to augment the sandbags on floors and flak jackets hung on doors. Wasn't exactly a fun time to be driving...

First- thanks to everyone for the great ideas. You've given me some great things to consider and opened up a bunch of options. Interestingly, I have no clue what the real purpose of those two rectangular holes are for but they work great with our forklift when I need to jack up the front end...

Not really an option. My bumper is welded to the frame but it's also cost prohibitive to change it out. After thinking about it last night, I might be able to borrow 98G's design but I won't know for sure until I get home next week from my travel. Will let all know what I find out.

Those are nice brackets. Simple yet effective. Unfortunately I don't think I have such a simple fix for my front bumper. I do have two tow hooks (loops) I could shackle up to the tow bar but they are at odd angles and will have a lot of slop in them. While using shackles will be effective...

I never thought about using a military tow bar to flat tow my truck as I was stuck on using a trailer or such instead. But that is a good idea. I'll have to think a bit on how to attach my tow bar to my 1-ton Ford with a Ranch Hand replacement front bumper but I think I can make something...

Here's the scenario: Pick your flavor of M939 series truck with a NHC250 is located 200 miles away. Seller says truck runs, tires are good, and license tags just ran out last month. The only issue is it's hard to start and dies at idle if you don't keep the rpms up (sounds like air leaks in...

I hear ya, CSM, and agree with what you're saying. I was really hoping to self-recover the truck as it's parked in an area behind a barn. The owner said I'd need to arrange it to be towed out as a typical RGN truck/trailer wouldn't make it to the truck. So you're right I shouldn't fix another...
