Actually, you do. You have "de-fueling" every time you take off from a light. The governor controls the engine speed. The throttle is nothing more than simply a request signal for desired engine speed/power. There is a spring loaded air pressure diaphragm on the back of the injection pump...

The RV guys show that a less restrictive muffler helps greatly in lowering EGT's. They seem to be the largest group of personally owned 8.3 engines, and they are always seeking more hp and mpg, so I study there. A lot of them use the Aeroturbine 4040XL muffler. Advancing injection timing is...

Cummins part number for this 6CTA8.3 military engine belt tensioner is: 3911621, as found by using the free Cummins Quickserve site and using my engine serial number (ESN), 1990 BMY M925A2. Sorry, unsure of any aftermarket replacements for it, but at least this does give you a source for it...

Not a wrecker, just have wrecker envy. Some good ideas in here. Besides conventional hand tools, 2 things I keep on board that I didn't see mentioned is $100 cash in a hidden place and the lowest cost new Stihl chainsaw with a new sealed can of ready-mix Stihl Motomix 2 stroke fuel, supposedly...

No, we just dragged it in park. No wonder why I got 2mpg. Now the tires are square. :driver: Yes, seller had the brakes released already to move the truck around as he parted out the front end. He was generous enough to leave the studs and nuts in the brake chambers. I'll need to route...

Next step will be to shorten the frame rails, notch, heat, and bend them in a V, and then reattach the 3" lunette ring to a gusseted plate. smittyjr was great in that he left everything: air tanks, air dryer, ABS unit, rear pintle, steps on both sides, tool boxes, etc.... I want the trailer as...

Touchdown! The 1/2 M923A2 is now at it's new location. Took my dad with me, and we bolted a cross member onto the very front of the frame rails, and then attached a lunette ring to it. Had to be careful with turns because the tongue is not into a "V" shape yet, took my civilian 2" receiver...

Thanks bud. Pedal to the metal in route now. More pics later tonight.

Went to pick this up couple days ago on my dads equipment trailer, and it is just too big. Having another go at it tomorrow (today), this time going to bring a fabricated hitch to bolt onto the exposed frame rails and tow it directly, hang some tow lights off the back.

The aftermarket governor springs which are available were designed for the Bosch P7100 pump commonly found on the early Dodge Ram 5.9L mechanical diesel engines. They have been proven to fit and work in the Bosch MW pump, but will have a lower than specified result (as mentioned above, a 3k GSK...

Some reassurance, my gauge behaved exactly the same. Would read mid scale on cold start, and then on the zero pin once warm. This was as received, and also after replacing the sending unit, and gauge. It concerned me so much when I was looking for a truck to buy that I asked each of the...

My pinion seal leaks completely stopped as soon as I ditched the spring loaded check valve vents and vented the axles to atmospheric pressure, ran tubes up high.

923 has 3.3 times the rated load capacity of a 105, so I didn't see that as a good way to go.

Fetching this trailer project tomorrow. Will post a pic of half-a-truck-on-a-trailer-behind-a-truck, and then hope to get the frame rails cut to length, notched, heated, and bent into an "A" with a gusseted drop flange to bolt the lunette ring onto before weekend end. We'll see.

I went with something a little different. It is cleaner, quicker, and has kind of an industrial look to it. Screwdriver and hammer not going to foil it very easily. Uses conventional pad lock of your choice. http://www.steelsoldiers.com/showthread.php?123521-5-Ton-Locking-Fuel-Cap-Easy

Why would they punch a hole in the bottom of the tank when there is a drain plug?

Surprised nobody mentioned thermostat. Is the engine running at 180F? A diesel will almost not even warm up at idle with no load. I changed my thermostat, and flushed the heater core, still no heat. A buddy said to change the heater core and that did the trick, even though it flowed well...

If you are trying to reach target pressures at idle, the system can time-out if leaks in the air tank system are prevalent or you air governor threshold is set too low. Raise idle to 1500rpm with the cable or try it while driving.

Yes, fully charged batteries are step 1. Block heaters work great, but aren't really needed on the 8.3 until you get pretty cold. What is the coldest overnight temp you could guess you would want to start the truck the next morning? Clean fuel filters and diesel fuel with anti-gel in it goes...

You need to decide that, not us. You are not indicating what vehicle or engine you are talking about, and what the coldest temp is you will be starting the truck. Try without, add as required.
