The failed plug in the picture has seen some severe heat. Either too much fuel, or something wrong in the precombustion chamber, directing the detonation towards the plug instead of down into the combustion chamber. Do you have any way to disconnect the fuel line from that injector, and another...

You say "melted". Are they just burning out, or are they actually melted?

It is possible that you have a 12K gear. Many years ago I wanted to increase the strength of my axles, and bought an 12K upgrade kit from SAX, which involved replacing the 10K gears with 12K gears, new bearings, and 12K axles. Both gears fit in the same housing.

Check the washer that the bolt goes through to hold the shaft in the gear. If its deformed (or the wrong washer), and binds against the housing, it could cause the bolt to back out when reversing. Also check the distance between the bolt head, and the hole plug. Compare the left and right side...

Have you tried the manufacturer? ELTAM is in Israel. Lighting for Armored Vehicles (eltam-eh.com)

I just did a google image search on the picture he is using on his Facebook page. It is the same picture as the workshop picture on the "Military Truck Works" website. Look at the shelves, the lifts, and the sand blast cabinet. Our Shop | Military Truck Works I just sent them a message to let...

Could be as simple as a bad wire, or bad or disconnected sensor. First, start by pulling the transmission error codes to see if they point at a specific error. Look at TM 9-2320-280-20-1 section 2-35 and the attached document. In my case it was a bad TPS signal.

Could be low voltage. Check the voltage at the solenoid when this happens. It could be a weak battery or bad connection. When cold starting, and the glowplugs re-energize while cranking, the voltage could go low enough to drop out the solenoid. Do some more testing before replacing anything...

I carry way too many spare parts. - Starter (overkill), Waterpump - major work to "field replace", all liquid filters, and many more...... Definitely carry a set of good tools. Small hydraulic jack (Test it to make sure it has enough lift to lift a tire/axle). But what I have had to replace...

I have a 5 kw unit mounted on the top of the Helmet Top tool box, inside the truck, with the exhaust routed outside. I added a 1.5 gallon tank, since I like to run Kerosene for the cleaner, odorless burn. Power comes from a 12v Lifepo4 battery. There is a 2" hole in the top of the box to allow...

To be clear, the plastic piece that broke off wasn’t from shut off solenoid, it was from the secondary solenoid that has a wire inside the pump, I don’t know what that is for, older humvees don’t have that solenoid in there injection pumps The smaller solenoid is the cold advance solenoid.

The galvanized piece is a heat shield that goes over the exhaust manifold. P/N 12339175. there is another small piece that goes on the end.

I found Spray Carburator Cleaner works great for unsticking stuck fuel pump plungers.

Some questions to help us understand the problem better. Did the unit ever run correctly before the single phase conversion? Did it ever run correctly after the conversion? Is the engine laboring, like it's under full load? Does the current go up immediately, or only when the contactor is...

All that rust makes me wonder what the inside of the frame rails looks like.

Take out one of the HID bulbs and compare the base to a halogen bulb. You may be able to replace it with a regular h8 or similar bulb.

At todays' prices, they just need to fill the tank full of diesel.

Well, my curiosity got to me, and I did some further research. One of the NSN documents I found says it is a pressure output port, but not for what purpose. Possibly for a capillary to an actual pressure gage? The doc states "sensor shall have one pressure input connection, one electrical...
