Had a situation where my 1123 would be ok while driving then suddenly cut off like you turned off the ignition switch. Been going through the TM's and following the flow charts to no avail. Very frustrating. The previous owner said he replaced the fuel filter and I took him at his word...... In...

Thank you for the offer. I dug around in the garage and found one hidden away from my 998. The new headlight either had a bad low beam or was broken. The old one works fine now. Thanks again.

The lens on the bad one was all clouded over white. It was shot. I'll do some continuity tests tomorrow on the connectors and voltage checks.

GE headlights New Old Stock NSN: 6240-00-966-3831 has the 20 in the glass on the 12 o'clock position

Burned out headlight on my M1123.... Bought two new oem ones. The right light has low and high beam, however the right one only lights on high beam...no low. The lighting wires are tied together so if the right low is working I'd think the left one would also. Maybe it's possible the the joint...

So with the screwdriver.... If it cuts off it's too advanced, if it doesn't do anything it's retarded and if it shakes a little then smooths back out when you release the plunger it's ok?. My M1123 seems a little rough idling right now...

You are correct...it is under negative pressure and connected to the high water intake stack. Brain fart on my end.......:mad:

My 1123 has the deep water fording setup. Parallel to the tall air intake stack there is a small diameter metal tube that connects to the DWF tubing. It goes through the fuel tank vent filter and is the vent for the fuel tank. Way above the 5' of water. The air to pressurize the system comes...

One definitely goes down to the nipple on the fuel pump...

Been reading here on IP timing.... Checked mine, visually, and it looks like it's retarded, toward passenger side. Seems like alot, looking at it compared to the scribe marks on the housing and IP. Aren't they pretty much lined up with each other. Thanks.

Thank you.... Hopefully that will cure it. The engine stops like you turned it off but the lights and electrical stay on

M1123 6.5L. Had the truck die twice now on two short test drives. Turned the start lever off and back on and it fires back up. Folks said to check #54 at the fuel cut off solenoid and check the fuel filter.... Just noticed that the fuel pump has a nice leak.... Obviously, going to replace the...

I appreciate it. Thanks

Am I correct in that armored vehicles have the spacer like yours and the unarmored bolt to the body (with the rubber insulation grommet). Thank you.

I took the truck on the left (as received) and changed it into the one on the right in three days.... Advil is my new best friend😁.

Could you possibly give me the length of the spacer between the pipe bracket and the truck body? Looks about an 1-1/4" to 1-1/2". Thanks.

Mine was a USMC M1123. The pipe was removed and I assume all the small stuff git trashed. It does gave the inner fender support so it came with the dwf setup.

Original military ignition switch..... For the #54 lead check is the truck running or just the ignition on. Thanks

I'm going to check the fuel tank vent filter as well as the batteries. The previous owner said it did it to him once and the cable terminals were not tight.

I know it could be several things however..... 2000 M1123. 18,560 miles. I just got it. New fuel filter, engine oil and filter. Glow lights come on normally, go out and then truck starts immediately. Sounds normal..... On the way to my local transmission shop to get a fresh fluid and filter...
