How did you do this? And where is the interlock you're talking about? Thanks!

Hey guys fully servicing my newly acquired 1991 m923a2 today. Changed both fuel filters and got it back running without problem (thank God). But when I opened the canister to look at the air filter I noticed there was a large amount of what seems to be gear oil inside the bottom on the case and...

On my recently purchased M923A2 the passengers side from tire is worn pretty well on the outside. Drivers side tire and all other tires are fine. I'm wondering if this is either a tire or possible alignment issue? I was thinking if this was an alignment issue that the driver side would be worn...

Ok guys... new 5 ton owner here about to change the fuel filters on the truck I just picked up. I've downloaded and read the TM's for the procedure but have also read the nightmare posts on here about not being able to get the trucks primed after changing the filters... so just double check me...

Sounds good plan to do a full fuel filter change ASAP, hoping that's what it is. Would make perfect sense though! Guess I just skipped over that part since the engine seemed to be running so good all the other times, but that makes sense when it hits the hills and goes under a load and needs...

Former deuce owner who just picked up a 91 M923a2 with the turbo Cummins in it. Drove it home from Charleston and didn't notice the problem until I started hitting hilly areas around my home state. The truck has a boost gauge and will put out 25-30 lbs of boost. When going into the bottom of a...

FloridaAKM I know exactly what you're talking about. Mine was so gunked up I had to take it out to get fuel in the tank. the wire mesh on my fuel pump looked the same way idk how the truck was even running. After looking around and talking to some people I decided to just get a new tank and have...

Hooray for us WRAFB trucks and nasty fuel systems! Mine was the same way... the screens on the fuel pump were completely covered with that tar-like substance... I looked into getting the tank cleaned or cleaning it myself but everyone said the baffles make it difficult and no guarantee of...

Gentlemen I just finished installing a brand new fuel tank on my WRAFB deuce that had a absolutely nasty fuel system. I have a brand new tank and took the fuel pump out and cleaned it well and it's clean as a whistle now and works great. I have also changed all the fuel filters. The truck runs...

Looks all too familiar!! Idk what was going on there at Warner Robins for real! I'm surprised these trucks even ran to be honest with you. I'm curious to see how it drives with the fuel system clean bc I honestly didn't notice any driveability issues with the truck even though all my parts...

Yeah mine looks exactly like the pics that y'all posted. My fuel strainer was gummed up with that stuff so bad it had to be removed to put fuel in the truck (should have been my first warning sign!) I will def have to try some of that cleaner and see what it does, def couldn't hurt. Also...

Hey guys I'm starting to overhaul the fuel system on my 87 m35a2 and drained and dropped the fuel system today and the tank is an absolute mess. It has a thick, sticky, tar-like residue on the inside of the tank (bio-diesel reside?). I took the fuel pump out the tank and it is covered in all...

Ok so I have an 87 a2 model and I just changed all the fuel filters on it recently and ever since then I have noticed a fair amount of white smoke coming from the exhaust while running. While idling it is very visible but it comes out pretty steady while driving the truck... I know in the 3/4...

I am a new member to the forum. I plan to attend the rally but I believe with my work schedule I will only be able to stay for two days (either Fri-Sat) or (Sat-Sun). I am not military but I am a RN who works at MCG in the Emergency room so I have medical training and will be more than happy to...

Truck already has a ground wire. Will double check and make sure it's actually grounded tho!

I have a 1987 M35a2 that I recently purchased and I'm having problems with the fuel gauge. The needle on the gauge is always to the right past full. I'm wondering if I'm going to need to purchase a new fuel gauge or the sending unit that is in the tank?? Are there any quick tests or tricks to...

I found the 3 trans vent lines and I can freely blow air into all of them EXCEPT the smallest of the three. Could this be the problem? And what is the easiest way to unclog these vents? And are they easily accessible from the bottom of the truck? I don't want to blow compressed air into the...

Ok thanks! I figured some line somewhere was clogged. Where exactly is this vent line?

I have a 1994 M35A3 that has been running flawlessly and no problems at all. When I got it back in May I changed the trans filter and checked and topped off all the fluids. Today I drove it back from where I keep it and when I went to check the trans fluid level it started overflowing from the...
