Hey guys, We just bought a 1984 M936 with the cummins NHC250 motor and on the drive home it seemed like it didn't have much of any power. Now I know that it is a non-turbocharger engine but on a few hills the speed would drop off to 10 mph. During the climb, it didn't produce any black smoke...

Hey guys, I just got done with an oil change/ fuel filter change on my a3 but I can't figure out how to reprime the fuel system to refill the fuel filter and get the air out of the system. I don't see any primers anywhere and I can't hear the fuel pump when the key is in the on position. Any ideas?

Well today I was fixing any leaks that I found on the truck and at first I found a leak where the plastic threaded fitting of horn hose screws into the brass connection so I added some thread sealant and that stopped that leak but then it started to leak between where the black hose connects to...

Does anyone know the exact cooling system capacity of 1989 P&H HSHMC 25ton crane? I am wanting to flush the coolant before it gets too cold and I need to know how much coolant concentrate to add to get a 50/50 mixture. Thanks

Has anyone ever changed out the original tires on their m105a2 with the 14.5R20s? I would like to have the trailer tires match the ones on my m35a3. I am just a little worried that the extra width of the 14.5R20 tires will be too wide for the trailer and will hang out far beyond the wheel wells...

Hooked my m105a2 up to the m35a3 yesterday for the first time and It didn't take me very long to notice that every now and then the brakes will lock up. I had already started the trip so I just turned the valve for the service and the valve for the emergency air off. about 5 minutes later the...

I posted this thread in the paint and body works section and didn't get any bites so I want to try this thread in the trailers section instead. I am wanting to to a paint job on my m105a2 and was wondering if anyone was any recommendations of what paint I should use. I was thinking of using an...

I am wanting to to a paint job on my m105a2 and was wondering if anyone was any recommendations of what paint I should use. I was thinking of using an oil based O.D. green and just use a spray gun to apply it but I am open to suggestions.

I just picked up a 1984 m105a2 out of Minot AFB in North Dakota. When I went to get it I realized that it looked different from the pictures that GL showed it as but I looked the the GL stickers and its data plate and everything matched what I was supposed to get so I decided to take it anyway...

Does anyone know how to adjust the air pressure that the CTIS puts in the tires on an m923a2? The tires air up to 70psi but with a tank of water on it the tires get pretty flat so I am wondering if anyone knows how to adjust it to 90psi instead of 70.

The other day I went to a garage sale and came across a great buy on an old USMC jerry can. It was only a buck so I thought that even if it leaked it would only be out a dollar so, I bought and tested it and sure enough it didn't leak. So here are pictures of me painting it from start to finish.

The other day I went for a ride in my m931a2 and about two miles into my trip I noticed that I wasn't building air pressure any more so I decided to turn around and go home but just not use any brakes on the way to conserve air in the tanks. When I got home again my tanks were both at about 55...

I am sure that this has been gone over time and time again but how can I tell for sure whether the tires or the CTIS is leaking on an m35a3? The back two tires are the ones that leak the most, they leak out in one day and the others take about a week. First, I sprayed the tires with soapy water...

After extensive searching I have finally found the air leak I have been hearing. I don't know what the piece that is leaking does or is so I was hoping you guys could identify it. It is located near the steering column. I have checked the TM's and had no luck. By the way it is and m35a3

I have a couple of quick questions that I am wondering about my m35a3. First, I have noticed that the front right knuckle boot is completely off. I am wondering if I just remove the guard if I will be able to get the boot back in place but since I am fairly new to the a3 I am wondering if I need...

I was just curious if anyone knows what this grey frame above the spare tire does. I have looked and haven't found any other trucks with it. Any ideas?

The other day we got a crane and today we went to drive it for the first real time because we just pulled it off of the trailer that brought it here. No matter what we do the crane won't drive/ or it will drive a few feet and then when we switch to another gear (ex: from forward to reverse) it...

I have a cane coming soon and I am wondering how to unload it. It has NO fluids so I can't start it to drive it off so I am thinking I can pull it off but in order to do that I need to release the air brakes. Does anyone know how to do that without starting it?

I was taking the m923a2 out for a spin today and I wanted to go in reverse because I missed my turn but I remembered that there was a big no no about going in reverse in either high or low. I heard that if you backed up in one of these that it would harm the transmission does anyone know which...

This is kind of a dumb question but how to you attach the spare gas can(jerry can) to the gas can holder on the drivers side of the truck. I am just wondering how to attach the strap to the can to keep it from flying off down the highway. pics would be great!
