New member Dave, just bought an M923 would like to say hello to everyone

[riellof5]

I just purchased an M923, with a friend of mine. We purchased 2 of them. They both ran great on the way home and now one will start and runs a couple of minutes and stalls. It will start up again in 5 minutes or so but goes back down. What fuel filters do thse take and where should I look for an air leak or fuel blockage? I have heard of your site and now that Im on it, it is most definitely the best site for the hobby, due to its members. Any ideas welcomed on why the truck will not run.

Hi--welcome to SS--There are many members with M923 trucks---good luck with the trucks--I do not know where the line may have an air leak but the members can help you--George

Hi welcome to the site. Your fuel problem sounds like a blockage of some sort, but not really an air leak. If it had an air leak you would think it wouldn't run after 5 minutes. I would suggest changing the filter and going from there. When it is running can you rev it up and does it have a surging idle? Anyways good luck an welcome!

 

[riellof5]

Hey Gents! Thanks for the warm welcome and info. Where can I get the fule filter? What things can be to regularly to keep the trucks running good?

 

[Farmallmilitary]

Fuel filter is NAPA 3401. All you can do to keep these trucks running good is just keeping up on your prevenative maintenance and excercising them fairly often. I have a record of when I do my maintenance and usually about 1-1.5 months I grease all the fittings. About every 2-3 months I check all the wheel bearings and make sure they are well greased. The best advice I can give is just keep up on the regular maintenance and that will prevent ALOT of problems in the future.

 

[riellof5]

Thank you!! I wil look to follow your suggested maintenance regiment. Should the air filter be changed too? If so I would like info on model number for that and the oil filter to be ourchased. How often should I change the oil?

 

[Farmallmilitary]

The problem with the air filter is that there is not a direct replacement out there. I would suggest just blowing it out and making sure it is clean. As for the oil the plateon the dash says something like every 6 months or 6,000 miles if I remeber correctly. Im not sure how much you plan to drive it but I would say every 6 months or whenever you feel that the engine needs it. I change my oil according to the color of it. I never let the oil get black. Maybe at most a dark brown. I think the engine oil filter is NAPA 1954 but that is just going off of memory. You can always look at the sticky's at the top of the forum for part reference numbers.

Let's see, you guys bought two 20,000lb vehicles and don't have any idea what you are doing. Does that sum it up?

Please start by reading the manuals. Before the usual suspects start calling the mods names for suggesting that someone do things correctly and actually read the manuals please remember that we do it so you will operate the truck properly and SAFELY.

Welcome aboard. The TM's and everybody here can help you, be prepared, if you did not consult the TM's or do a search you will most likely get a tongue lashing from the older members here.

 

[riellof5]

Thanks Patriot. I also thank Mr. SW for his constructive, informative and suggestive response. I am the commander of an army cadet unit in NYC and share this venture with the commander of another. Combined with have about 250 members to include a recent AIT graduate from a truck MOS. The trucks are stored in the motor pool of the largest armory in the US. They are parked along side active HMMVs, LMTVs etc. I was trying to get some pointers that we could do on our own but the national guard is available to guide us as well. I came on to this site because a friend with the same trucks said I would get a warm welcome and assistance but didn't mention I needed to take a course in these type of vehicles prior to joining the site or purchasing the trucks to help avoid tongue lashings. So I will chalk that up to someone not knowing all the facts before they start summing things up for me. Thanks again for the help, info and links. I promise to come back a more seasoned Owner and hobbyist.

Dave, some of the members have advanced testosterone levels, seems that driving big he-man trucks tends to bring that out in some folks. Hopefully when they mature, they will grow out of it and learn civility. Most of the members are pretty decent and helpful- and most of them started out as raw newbies that did not know a Cummins from a transfer case. We all learn, and the best way is with help from each other. As we used to say back in the day before many of these recruits were born "keep on truckin' man!" and keep asking questions. This should be a fun hobby, and not a he-man contest!

The military will not let a a new enlisted soldier near the operators postion of these trucks until they cover the tech manuals and are checked off to operate them.

The same is not true of civilian owners.

One reason the "older" guys harp on the operators manuals is that these things weigh in at 20K+ pounds. They can and have killed people. A couple of years ago a seasoned member here was killed recovering a new truck. Another member had an accident and killed two teenage girls on thier very first MV ride. And a "ride" operator had a equipment failure and killed a couple of his passengers.

Yes we get grumpy but it is for a reason. We want people to be as safe as they can.

And to the OP, Welcome to the Best MV website. Had you introduced yourself with all the additional info you provided, someone might have not thought you where a 19 year old that just bought his first truck and wanted to hotrod it.

I have seen the same thing on trucks just being released. I would recommend changing the fuel filter first. Read the tm procedure and follow it. I always use the new gasket provided with the new filter. Make sure the filter is tight. put some fuel treatment in the tank to get out any crap. I recommend sea-foam.

Oh welcome to the club and enjoy the truck, it looks real nice. check out the Weare NH rally. it is the thursday the 25th-27th. It is a great event for the whole family.

I have no problems with grumpy moderators, they are simply doing their job. A manual and proper training in operating a large vehicle with airbrakes, is a must. Just because you found some "antique" loophole to avoid getting a CDL, does not mean that it is not your responsibility to learn to operate these vehicles safely.

Make sure that your cable operated emergency shut off valve is completely in the open position; otherwise a partially closed valve could give you the same symptoms. This needs to be reset and opened under the hood just above the pump, just pushing the cable in will not reset it.

Hi Dave--check out this thread--http://www.steelsoldiers.com/showthread.php?79327-M923A1-losing-prime

Welcome, another option to look at is run the truck with the Fuel cap off if the problem clears it may simply be a clogged fuel tank vent tube
