- Today I go under the truck to see why it won’t drive. We find the problem which is a cracked trans pan. Sadly it’s a bigger project than I thought!

I worked at Stewart and Stevenson - Armor Holding's - BAE Systems for 12 1/2 years in Sealy, Texas where the truck was built from ground up !! I was in sand/shot blast !! E-Coat 1 I was there to have a hand in building the first 10 thousand plus truck that rolled off the line !! Those trucks were Awesome at The Time !! The (carc) paint tan and or green , Black and brown was a unique paint !! 👍👍👍
I can guarantee there's a government manual somewhere that says you have to pull back the drive shaft before pulling out that pan. The government allows such known factors in maintenance.
On the F-16, it takes around 48 hours to pull an engine out, roll it back to inspect it, then reinstall it. A team of 8 can do it. You're working solo on a truck. You're probably meant to have help with a lot of those things.
I used to write service manuals for the military (it’s subcontracted to other companies) and I was working on an update to this type of vehicle which was being made by a new manufacturer. Anyways, the military style of repair is to not do this in the truck. If you broke the pan, you should actually remove the transmission from the truck prior to doing any repairs. They would have never sanctioned this kind of repair in the field.
And this specific issue is an Allison transmission design issue. I’m sure it’s meant to remove the T-case from the trans before pulling the pan.
There is a manual on how to do this but your talkin about 3rd echelon, not a field repair.
It's always a good idea to have the shafts checked and balanced.
i love when people are looking at a beautiful machine, a marvel of engineering. Engineering because engineers designed every single aspect of it. Tolerances, reliability requirements, thermal challenges, fluid dynamics, performance requirements, torque and force calculations, finite element analysis, corrosion, material interactions, and icould go on and on. All the while making trade off decisions. in this case probably around center of gravity and ground clearance (I’m speculating). But then guy with wrench comes along, knows better and degrades an entire profession?!? Cool truck through
LOL ...you obviously had never built an off road truck in your back yard. Or even worked on a vehicle for that matter. I suggest you quit drinking the cool-aid... its making you libtarded.
Now, throw in there a first-time Start without checking every fluid level, then some serious maintenance without a Manual/T.O. in sight.
The Allison engineers are fine- the problem is with the people who designed the chassis. Typical problem when different groups of engineers don't talk to each other. If you think the pan would come out without those couple bolts then cut them off and replace them with shorter studs.
there is a master switch in the cab left side lower kick panel to cut out the main ignition switches on the dash. Second trans fluid is the the same oil in engine which is 15w-40w diesel oil. Caterpillar engine depends what year but range from250 HP up to 350 HP. If you send me your engine serial number i can look it up.
Oh lift on the front bumper will get more room when the axle stay on the ground and engine and trans raise up.
You are probably right. Lifting the body 8 inches onto jack stands should do it.
That's the first thing I thought when watching this vid. Also, seems just pulling the center "X" piece of the U joint would allow clearance enough. Or positioning the truck so the driveshaft rotates enough so the bolt misses the ends of the the driveshaft?
A drive shaft puller?! i pull those same shaft styles on a weekly bassis with a socket, pry bar, and a hammer 😅
I have looked at buying one of these. They were fun to drive back before I retired. This makes me leery of these auctions sites if I can't go inspect it first.
They are hit and miss. Sometimes you can get a really nice truck from them. Other times you can get a problem truck. I’ve had good and bad luck with them.
@@abmotorsports9517 I think the biggest issues we had with LMTVs were usually with the ATIS. Tires would always go flat over time.
I work for S&S and we get these in the shop from time to time. Most of the time the owner had just bought it from auction and has LOTS of issues. Some cost more to fix than they paid for it. They're tough little trucks but sitting for God knows how long, under God knows whose care, in God only knows what conditions tends to really take its toll on em.
Step one, remove transmission, Step two fix trans, Step three install trans... Onward!
Bent driveshafts and cracked pans probably match the forklift jaws from loading the vehicle onto a trailer.
Thank you for the view. That’s what we think the damage came from too. Just replaced the whole transmission. New video coming soon on it running and driving!
I just got the exact same truck from Govplanet and has the same problem!
Most trucks that come from there do have problems.
How much did you guys get yours for looking into one
@@vr4junkie385 I give $3500 from Govplanet, $500 in auction fees, $500 in taxes and broker fees,$1900 to ship
@@huckefinwoodcrafter308 not bad price wise I'm wanting to get the larger 6x6 version then turn it in to a wildland fire truck for doing prescribed fires and federal fire contracting there a great chassis that's capable of having a 1000 gallon tank.
The cat motor is a plus but I wish they were Cummins (Preference)
But parts and service availability is critical for my application the truck will be going to the west coast alot from the southeast (arkansas)
I'm worried about the little things like getting the truck dot compliant finding tires finding parts for the inflation system
@@evandickens3917 did you find one?
Go to steel soldiers to learn how to work on your truck.
Also, the military made some good technical manuals.
Do you have measurements on the body itsself?
Was you ever able to get this truck running? I got a truck from government planet that was stated that the front drive shaft was bent. The same as yours. In the pictures I couldn't tell that the drive shaft was bent. Did you ever get your lmtv transmission working correctly?
I got the truck running, the transmission has problems, they ran it without any fluid and burned up a lot of stuff doing so.
Seems everyone gets the same "bent driveshaft" notification. Could it be they expect to bend the shaft from manhandling the vehicle during transit and cover their butts this way?
Hi - i like yr video. Can you tell me whats the Diesel consumption for yr vehicle- if you drive normal on the street 45-55 mph. THANKS
About 8mpg or 300 miles on 50 gallons approx.
I've worked on these an its about 5-6 gal. per mile standard
Great content
Yeah, it’s a piece of equipment,……you have to be able to turn a wrench!
Call Stewart and Stevenson for a copy of the repair manual.
it’s because a bunch of soldier wrote “no new faults” every week
It’s design for a one way ticket
Was this vehicle prior Army?
Where can I listent to the music at 3:45?

@@abmotorsports9517 cool, thanks a ton.
This is what LOWEST BID gets you, when government buys these trucks, I cannot imagine what nightmares these faulty designs have caused on tthe battlefield.
That is very true, thanks for the view!
Lol.
Here is a link to someone removing the filter, and not pulling the driveshaft. ruclips.net/video/iG58LlYCrlM/видео.html
Thanks! That will come in handy later.
"Engineers design things without actually knowing what they're doing". Lmao! Yup. When built new, some of these machines wouldn't even start and were shipped out the door. Quantity over Quality was the motto.
Remember gov. Buys LOWEST BIDDER
What...No air tools ? .....
He needs alil cheese with his whine.
They didn’t pay engineering to do it they forced it to produce
It shows lol
LOL, welcome to the real world.
Try working on a helicopter engine installed in an aircraft. Lol
The engineer only disigns the engine, he has no idea where it's going to be installed or how.
You have to be a contortionist to work on some helicopter engines..LOL
I guess this guy never heard of a drain pan or a drip pan. Nice how some people are so concerned about their object that it doesn't matter about the consequences of environmental damages caused.
Forgot you were there to know there was a hole in the pan. Dip stick was dry. I added fluid not know the previous owner destroyed the channel and didn’t tell me.
@@abmotorsports9517 have you ever heard of a pre-trip. most people crawl around an auction vehicle and inspect things like that first. and pull strings on their drive shafts. inspect gaskets. etc.
