    What size socket to bar NHC-250 over?

    No, each pin fits loosely into the 3 large holes in the pulley. No need to mess with any fasteners. Sorry for the crappy doodle. If it was light out I would take a picture of mine. I'm currently in the process of changing #5 and #6 injectors.

    Rear-Front Axle Shift/Slide

    Greetings friends! Forgive me if this has been covered before, nothing on the topic came up in my searches. The rear-front axle on my M814 will slide left and right in corners. It shifts on the leaf perches. I can hear a clunk when it happens. I can also see when driving strait the sidewall...

    5 ton rear axle seal fix procedure

    Very nice write up! Thank you for taking the time to share and document so well! I need to do this job shortly. My rear rear axle is leaking like a sieve (both sides), the rear leaks a bit too, but not as bad. My fronts need new boots on both sides. Thanks again!

    What Are Normal Axle Hub Temperatures?

    Found this thread after checking my hubs today after a short 50 mph drive, and some around town stop and go. Checked by hand, no hubs were hot. Front and mid axle are warm to the touch, but rearmost is only lukewarm. Truck is unloaded. Just curious why the rearmost hubs would be cooler. Do they...

    Yes I have the stock NDCC 11.00x20 tires. If anything, the smaller diameter would make it easier to get to top speed, as top speed on these vehicles are limited by their low gears. I usually shift at 2100 when accelerating.

    I was under the impression that turning the screw was to be avoided, and the button should be replaced if you wish to increase fuel pressure. I could be mistaken though. Something I had wondered is how far is safe when turning up these engines. I know it depends on how you drive it and what you...

    When you say some were turned down, would that mean a larger button? I am curious as to what size button our trucks are supposed to have.

    Perhaps I will record a better one and post it here ;-) I spend a fair bit of time in 3rd gear. I don't know how much snow there is left. Been really mild here in Ohio, but I know NY is usually... not.

    Interesting! I have not checked my tank vent, but I have never noticed any suction when removing the cap either. I will check it, probably tomorrow. Good suggestion.

    45-50 Up a hill, will not happen in my truck, for sure. 35 maybe. I live in Ohio also, so a hill to me is not really a hill to some. But maybe you all are right. I will post an acceleration video sometime.

    No I have not, so I guess I don't truly know for sure, but is sure seems that way. It struggles to hit 55mph, even on long, flat stretches of road. It must be driven at full throttle to reach anything above 45. I am downshifting at the slightest inclines. I estimate 0-55MPH time is greater than...

    My ears are untrained when it comes to these big diesels. I am just going off my gasser knowledge, which I know are very different. As far as running it, it still has a low power problem, which I attribute to injectors for a few reasons. I don't think it is an air in fuel problem, as I have a...

    Another update my friends! The other day I went to start the truck, and much to my surprise, it started right up. Hit the starter for maybe 2 seconds.This time I had the primer lever pushed in... I did not record startup, but here are my temp readings after a few minutes of idling...

    Nhc250 valve injector overhead adjusting

    I found this video a while ago that explains the Cummins PT fuel system. The video, along with Wills words of wisdom, helped me understand what is going on and how it works. https://youtu.be/KzuwdxEJfQA The short section about the AFC can be ignored, our non-turbo engines don't have one. I...

    My truck has always been (at least until recently) an easy starter. When I bought it, it had sat for two+ years. It was like 13F outside, and it startup up (while getting a jump from another truck) on the second, 30 second cranking attempt. Usually it starts up within a few seconds of hitting...

    After checking the oil level, and draining a small coolant sample, I decided to attempt to start the engine.I recorded my experience.I was not brave enough to use the manifold heater, as I really did not want to possibly put any more liquid into the cylinders. It is 31F outside, so she wasn't...

    I figured it wouldn't be a problem to parallel them up to charge them, but I will heed your words and charge them separately. Its the glow plug eh? I see. I may have accidentally left that on (while driving) once or twice, but I don't think I have ever left it on for longer than a minute or so...

    Today I removed my batteries. They are Duracell Commercial group 31B's. Here are my voltage readings: As you can see, one of my batteries is very low! I did notice there is a 12 volt tap coming off the terminal on the low battery, so that must be what is causing the drain. I do not yet know...
