Hey guys...the old HETS ( 1993 > 2003 i think) only has the interaxle locks (axle to axle) and no differential locks ( wheel to wheel or side to side locks). They just have open differentials, thats why you see that sometimes both wheels have traction and sometimes just one wheel. The newer Hets have both locks. Now we're busy to add differential locks on all axles 😃
I was in the Army from 1995 to 1999 and worked on these trucks. They had full differential locking, inter-axle locking, and transfer case locks. This driver does not know what he is doing. Just turning the CTIS to "Emergency", and putting the T-case in to low range would have engage all of these locks, ensuring that every tire will turn at the same speed. Save the airing down until those don't work.
@@zacharyblaseg4177thanks for your reply. I think you talk about the PLS, that came with all locks since 1993. But the M1070 Hets don't have them. The newer ones m1070a1 has all the locks. I recently installed diff locks on this truck, since the axles only had interaxle locks. I just did the tridem and still need to do the front. They worked greattt. Just tested them last week. Will post some videos soon with the diff locks.
I think it might not have locking diffs. Not all trucks do. I am just guessing but the guy would probably use them, this being his everyday environment, if the truck had them..............
I learned when I was an combat engineer in Germany I started chaining up the front wheels and part of the rear wheels in the mud and it made the difference big time , like night and day.

I used to build those and HEMTT's a few years ago. Pretty fun to drive. The HEMTT's could drop the pressure in the tires for sand and mud but I don't remember if these could. They had diff lockers too and pretty sure these did too, I think the driver doesn't know what the hell he's doing.
@@musicboxz523 perfect observation! When I was in em, they went through basically anything on the test track. They had to stop on a 45° gravel incline (if I remember right) and take off from it or they didn't pass and got sent to be diagnosed & repaired. Oshkosh are some badass vehicles.
I believe those Oshkosh trucks have inter axle locks. Meaning all tires get equal torque when engaged, not an open differential like that. My 8wd hemmtt had it. If only one tire grabbed you could move. Had to be engaged manually tho.
I sure miss my HEMTT wrecker. Not very fast but it could tow damn near anything. On a couple ocassion I had to tow a HETT with a Kalmar on the trailer. Only thing that ever squatted the back of my HEMTT. FYI a Kalmar weighs more than a M1.

How do you have a truck in that situation with "offroad capabilities" and it doesn't have a diflock. That would have turned from a 5 minute struggle to a 30 second power trip.
+Pursuit918 How bizarre not having diff locks (or maybe the driver was not aware of them)! Even applying the brakes momentarily would have counter-acted some of that wheel spin.
+Pursuit918 They have a differential lock.. the problem is that the truck's 8 drive wheels were all spinning because the trailer acts as a massive anchor behind it, and the lugs on the 8 wheels were just turning bald from the slick mud so they had no traction.
+Pursuit918 all tires would have been slipping, a difflock only works when atleast one tire has traction. If you put any difflocked vehicle on a slope that was completely covered with a service with low traction it would do almost nothing.
+Randy Perkes their is always a little bit of traction, so if you put the diff on and run up the hill, the momentum and the fact that at least some of traction is used would pull it up no problem.
The tires are the limiting factors here. They are combination mud,sand,and hard pavement tread, and work well most of the time. However this clay/mud combination is simply too much for the tires. The lugs are not self cleaning when it comes to most mud, and especially in wet clay. If the tires had a tread design such as found on most farm tractors rear tires, this hill would be no problem for the M1070 at all. But if so equipped to be a mud runner, you would not be able to drive at the maximum speed of 47mph on the paved roads, or the farm tractor tread would fly apart and shred themselves. Those tires were never designed for higher revolutions. Hence the compromise tires that all HETTS are equipped with. These tires will handle lots of weight compared to mud only tires. This driver should use the CTIS and deflate for a larger footprint or bite.
Sounds like one of the older ones with a Detroit diesel. Rpms seem way to high too. I keep the wreckers low and never have an issue when I have to recover vehicles.

i remember driving a PLS (palletized load system) it has 2 front axles and 3 rear with these same tires(also made by oshkosh). i dont remember an axle lock because i never used it. it did allow for tire inflating/deflating while driving and that was all i ever needed to keep it from getting stuck. i wont say how crappy or great i think military equipment is but i do think this truck could go up this hill with an empty trailer no problem.
Very cool. CTIS in action (the hissing sound letting air out of the tires). I know these trucks have lockers but I don't know if it's limited slip or full lock. For this type of vehicle, I'd assume full lockers would be available (push button) which I did not see in the video. My 5 ton 6x6, surprisingly, does not have lockers but it'd sure be nice to have them. Game changer.
m1070 has three controls to to consider in this situation: high/low range on the transfer case, lockup/unlock on the driveline, and CTIS for the pressure in the tires. if you get stuck in a 1070 you are supposed to go to low range, lockup on the driveline, and emergency on the CTIS to take the tires down to minimum pressure. I think emergency on the CTIS might activate wheel to wheel locks on this truck but I get conflicting information. however one trick a lot of good ole boys know is that if you don't have a diff lock and you get wheel spin on opposite corners you can give some brakes and gas at the same time to get the wheels to bite
For a minute I was thinking that there just was not enough traction to pull the trailer out of the quagmire while going up hill. But their was, barely ! I thought it was cool that it was possible to select which wheels would get power - or was that the four wheel drive effect?
I drove a 10 ton m 125 in NAM we were taught the back and forth technique and it worked but I love the new military Oshkosh 1070 I think they are awesome.
+szili76 Well depending on the type of tires that is actually better. Many different mud tires are made to self clean and they have to spin fast in order to do that. So by spinning them fast they will actually get more traction in mud. If you were to keep going slow they would just pack with mud and that is pretty much no traction at all.
This Oshkosh HET M1070, sure looks awesome! Surely, this truck possesses the best of equipment for mudding. AWD, 8X8, huge tuff auto tranny, locking monster diffs, top loaded, straight drive lines, great wide tires, huge tires, But remember this. Soft , slippery mud , and a hill, is a huge opponent! I am very surprised, this unit, doesn't have as standard equipment a huge front frame mounted winch, with dyneema super strength rope to pull its way out of anything! How the driver handled the situation was poor to say the least. And there was no heavy load on the trailer to boot! Letting the Detroit 2 cycle diesel scream and burn, is not smart for anything, especially the tranny as the temperature climbs! Lessons? This was a winch job, do not scream and burn, and have plenty of respect for the bush, and mud whatever the rig you have! Be patient, and use your head, not your foot on the fuel. Be equipped to get yourself out, slowly and properly! This guy was lucky to have gotten out the lazy way! Experience is vital. Respect your equipment do not beat it! And park your egos and pride, it will save you money. kennethzakaib@gmail.com
All I know is in my experience, this truck is unstoppable in the right hands. Aka my hands. I've used this machine to pull sunken, overturned tanks out of the Euphrates river. This truck is a beast. Locking differentials and axles, high and low gear, 500hp Detroit diesel (can be tuned to 700hp without modification, extreme duty allison transmission, 2x 40ton 360degree swivel winches, deprogramable safety allowing 70 mph instead of 48mph Michelin extreme off-road tires, drum brakes all around, able to pull up to 150 tons (trailer willing) able to submerge 6.6 ft without problems. Can do burnouts in 8wd thanks to the transmission slip glitch behind 1st gear. All of this with automatic central tire inflation system with emergency inflation system that can improve traction on the most slippery of surfaces, matched with knowledge about ride-height adjustment and airbag control. Only someone who has no clue about the trucks capabilities gets slowed or stuck.
@@gckuisch there is a programer for Detroit diesels. It will control the boost and fuel pressure to take it out of factory "safety zone" it will allow it to get to 5000 rpm. It is how you take off the speed limiter too.
@@gckuisch the big things you need to know is if you have the DDEC II, DDEC III, or the DDEC IV. usually the years tell you which one you have, 1991-1993 is II, 1994-1998 is III, 1998- 2003 is IV. Oshkosh used the same engine in alot of different models. Heavy equipment transportation system (HETS), The Palettized loading system, (PLS) or the Hemmet series which was used from deep woods logging, to emergency response vehicles, to heavy munitions dispatching vehicles, to wreckers for the oshkosh series tactical multiversital vehicle lineup. Basically you would be using the wreckers tune on the engine. Which is designed to pick up and pull a fully loaded oshkosh system. rtrice66@gmail.com.
For all of the people commenting about the diff locks, he clearly had them engaged on his initial pass, it still didn’t work. So many people saying “I’ve driven one stop being an idiot” trying to talk themselves up. Galapagos het can drive just fine the tractor is just a dog, and you all know it.
Look at the angle of the water in the tank on the trailer. I didn’t think it would make it up the hill. The axles must be open or limited slip. I have wondered why they don’t use all wheel drive semi tractors on the roads in Alaska as shown on Ice Road Truckers.
@@mardievanbree8795 Chains wouldn't have been necessary at all for that terrain,and there wasn't any cargo on the trailer either,so it's just the rig and trailer that play the weight.The real issue is the driver who is inexperienced,those 15 Ton HET's all come with locks,and some versions are different than others,like having cross locks,power dividers,etc.But they all are beasts if you know what you're doing,both HEMTT's and HET's alike,just like MK's and MKR's are built for terrain like this.If there was ice or sleet,then I could see chains being effective because of barley to no grip on the tires.
@@Slim_Slid you just showed your experience level. Out in the oil patch (drilling for oil and gas, or fracking for some reason i felt the need to have to spell it out for you) we chain up daily for the same terrain. He could have used his johnny bar to to keep trailer tucked in high and straight behind him instead of letting trailer drift on him
tire failure - i learned in snow if you have a thread pattern that can not clean itself you will fail. there needs to be groves that let the mud out of the treads.
"Dump tyre pressure"???...Wrong, TOTALLY WRONG...Air down in "bottomless mud", but maintain higher air pressures where there is a solid base beneath the mud (as is in the roadway in this vid).
El problema es que no lleva peso y no cuenta con traccion adeacuada.. Pero no le veo usanso el diferencial al conductor ... Va a quemar el motor asi..... HERMOSO CAMION POR CIERTO 👍
In germany i had the same problem with my 5 ton mud was slick , so i chained all the outer tires to includ both front tires made all the difference with snow chains.

This machine is made to carry Abraham tanks at a max speed of 45mph. The car will only perform as good as the driver is. In this case someone drag him out of that vehicle before I loose my mind!
@@Slim_Slid For that transmission, this was really a walk in the park. There's virtually no load on the drive train here in comparison to steeper hills with a heavy load and good traction. If I recall, the military requires the truck to be capable of pulling a load at very low speed (worst condition for overheating) that requires running at full throttle and to be able to do so for an hour on a 100-degree day without any appreciable increase in operating temperature. This truck was definitely just loafing compared to what it is capable of.
@@ericl2969 Your wrong on a few things. Just because a truck has to move something at low speed does not necessarily mean to run it at full RPM. Giving it that much Throttle non stop will overheat both Engine and Transmission,this is common sense,not rocket science. The M1070 used a DD-92 Detroit making 550 HP & 1,996 lbs of Torque while other 15 Ton Variants from Oshkosh made 500 HP & 1,470 lbs of Torque from a 8V-92.The HET uses a CLT-754 Allison Automatic with a TC-496 Torque Convertor.Now,the Military has the M1070A1 with the C18 from Caterpillar that makes 800 HP & 4,000 lbs of Torque,with a 4800SP Transmission.If a M1070A1 still has a CLT-754,then that means it originally was a M1070 with a Detroit before being Rebuilt with a Caterpillar. The M1070 HET is rated for 45 to 50 MPH only,so there is a reason on instruction for low speed which you are trying to describe. Aside from RPM and human error,it depends on Transmission,Transfer Case,and 8×8 to know how to move Weight with a Oshkosh.Depending on Gear,Range on the T Case,and Low/High on 8×8,is how you move,regardless at what MPH you are moving at,and if you are not going nowhere at high RPM,then you are the problem.The M1070 & M1070A1 both also have CTIS (Command Tire Inflation System) on the 1600×20 Tires which allows them to Deflate/Inflate depending on what Terrain or Situation you are in,so that adds a bonus for Off-Roading in a 15 Ton Truck.The Heavy Equipment Tractor is actually rated for 230K lbs,but being risque with one of these will expose their weak spots,they bend they break like anything else on this world.In the Army,they use up to 170K lbs most of the time on them with a M1000 Trailer and they usually will haul Abrams Tanks and M109 Tracked Howitzers most of the time.
@@Slim_Slid What I tried to make clear is that the truck is specifically designed to be capable of running at full-throttle and high load demands under the most extreme conditions the Army could come up with for testing purposes -- and to do so without overheating. This situation really wasn't that bad in comparison. Even if the engine was maxed out on revs, which it probably was, it wasn't actually working that hard because conditions were so slippery, so since generation of heat within the transmission is mainly a function of the work load, this just wasn't that severe of a situation. Was the driver being an idiot? Probably. Was it hurting the truck? I seriously doubt it. Not when you consider the incredibly severe driving conditions under which the truck is required (by the Army) to be able to tolerate.
All M1070 HET's come with differential locks,the 1993-2003 Variants had Interaxle Locks which acted as in one set of wheels would move slower than any other one if the rig got stuck in somewhere.If it didn't have locks,then hauling a Abrams Tank out in the sands would be more of a pain in the ass.
what aboutl axles lock or at least power divider lock in the diffferentials? with the dimension of that machine should be part of the basic equipment to face this hard condition's driving
Amazing vehicle and ya you can see when he locks his diff's I had an older Toyota I had to get out and lock the diff's and that little truck pulled a few full sized ford's out of mudholes. But it was the 1400 bucks I spent on tires that did it. Loved that truck.
I had a '74 Toyota Land Cruiser. It too had locking hubs. A guy told me he hated them because he got tired of getting stuck in the mud, having to get out to lock the hubs and getting all muddy. I told him i never got muddy, would lock them in Before off roading. He looked at me dumbstruck ...
More than likely a DD-92 (DDEC/Electrical) other than 8V-92 (Mechanical).Most M1070 HET's run DD-92's with 500 HP and 1,996 Torque.The recent or rebuilt 1070's now run a C18 6NZ Caterpillar with only 500 HP and 1,470 Torque.

Very cool. CTIS in action (the hissing sound letting air out of the tires). I know these trucks have lockers but I don't know if it's limited slip or full lock. For this type of vehicle, I'd assume full lockers would be available (push button) which I did not see in the video. My 5 ton 6x6, surprisingly, does not have lockers but it'd sure be nice to have them. Game changer.
[5:32] - That logging road looks challenging, but the truck handles it like a champ!
What is needed here is obviously SIX SETS OF TIRE CHAINS. Best investment a trucker can ever make. Those triple drive Oskosh tractors are awesome!
Edward Jonez tire chains for mud ? 😂 yeah ok
Works like a charm, obviously you've not been offroad much.
Every weekend in the summer
If you are dragging large trees around going over downed trees brush
Actually ALL axles are driven, as you can see!
Came here for all the super mud truckers. Wasn't disappointed
This truck Would of made it right to the top with the first attemp
With an real truck Driver
The guy behing the Wheel sucks
No it’s the other way around, the diff locks aren’t working or aren’t. If you go up a slippery slope buy a Kamaz D535 for example.
m1070 has three controls to to consider in this situation: high/low range on the transfer case, lockup/unlock on the driveline, and CTIS for the pressure in the tires. if you get stuck in a 1070 you are supposed to go to low range, lockup on the driveline, and emergency on the CTIS to take the tires down to minimum pressure. I think emergency on the CTIS might activate wheel to wheel locks on this truck but I get conflicting information. however one trick a lot of good ole boys know is that if you don't have a diff lock and you get wheel spin on opposite corners you can give some brakes and gas at the same time to get the wheels to bite
wrong gear and no throttle control. There is nothing wrong with the truck!!
I think the driver has a problem not the truck
Did you even watch the video lol he hit the hill in low doing wide open almost
छह
Its an automatic genius
So?
For a minute I was thinking that there just was not enough traction to pull the trailer out of the quagmire while going up hill. But their was, barely ! I thought it was cool that it was possible to select which wheels would get power - or was that the four wheel drive effect?
Wow, Spintires graphics and physics have improved a lot
Lol its not a sim game XD
@@conzector0171 wooosh
I drove a 10 ton m 125 in NAM we were taught the back and forth technique and it worked but I love the new military Oshkosh 1070 I think they are awesome.
You should give full throttle at once so all the wheels start spinning. That is the best way to get traction!
+szili76 Well depending on the type of tires that is actually better. Many different mud tires are made to self clean and they have to spin fast in order to do that. So by spinning them fast they will actually get more traction in mud. If you were to keep going slow they would just pack with mud and that is pretty much no traction at all.
they need to add slippery yet shallow mud like this in snowrunner
This Oshkosh HET M1070, sure looks awesome! Surely, this truck possesses the best
of equipment for mudding. AWD, 8X8, huge tuff auto tranny, locking monster diffs, top loaded, straight drive lines, great wide tires, huge tires, But remember this. Soft , slippery mud , and a hill, is a huge opponent! I am very surprised, this unit, doesn't have
as standard equipment a huge front frame mounted winch, with dyneema super strength rope to pull its way out of anything! How the driver handled the situation was
poor to say the least. And there was no heavy load on the trailer to boot! Letting the
Detroit 2 cycle diesel scream and burn, is not smart for anything, especially the tranny
as the temperature climbs! Lessons? This was a winch job, do not scream and burn,
and have plenty of respect for the bush, and mud whatever the rig you have!
Be patient, and use your head, not your foot on the fuel. Be equipped to get yourself out, slowly and properly! This guy was lucky to have gotten out the lazy way!
Experience is vital. Respect your equipment do not beat it! And park your egos and pride, it will save you money. kennethzakaib@gmail.com
Not an expert here but i am not convinced these are the tires for that kind of job.
They're offroad tires. Not much to choose from in that size. Chains are really the only thing that would improve traction.
That engine noise ... holy shit
All I know is in my experience, this truck is unstoppable in the right hands. Aka my hands.
I've used this machine to pull sunken, overturned tanks out of the Euphrates river. This truck is a beast.
Locking differentials and axles, high and low gear, 500hp Detroit diesel (can be tuned to 700hp without modification, extreme duty allison transmission, 2x 40ton 360degree swivel winches, deprogramable safety allowing 70 mph instead of 48mph Michelin extreme off-road tires, drum brakes all around, able to pull up to 150 tons (trailer willing) able to submerge 6.6 ft without problems. Can do burnouts in 8wd thanks to the transmission slip glitch behind 1st gear.
All of this with automatic central tire inflation system with emergency inflation system that can improve traction on the most slippery of surfaces,
matched with knowledge about ride-height adjustment and airbag control.
Only someone who has no clue about the trucks capabilities gets slowed or stuck.
Hi, that sounds interesting. Do you know how we can tune it up to 700hp and 70mph? How can i contact you?
@@gckuisch there is a programer for Detroit diesels. It will control the boost and fuel pressure to take it out of factory "safety zone" it will allow it to get to 5000 rpm. It is how you take off the speed limiter too.
@@gckuisch the big things you need to know is if you have the DDEC II, DDEC III, or the DDEC IV. usually the years tell you which one you have, 1991-1993 is II, 1994-1998 is III, 1998- 2003 is IV. Oshkosh used the same engine in alot of different models.
Heavy equipment transportation system (HETS), The Palettized loading system, (PLS) or the Hemmet series which was used from deep woods logging, to emergency response vehicles, to heavy munitions dispatching vehicles, to wreckers for the oshkosh series tactical multiversital vehicle lineup.
Basically you would be using the wreckers tune on the engine. Which is designed to pick up and pull a fully loaded oshkosh system.

It sure does have enough power to spin the wheels. I'm quite impressed.
Is this thing got a 8v Detroit or a 12v?
Probably 8V92t
they had a 8v92 silver
It doesn't have difflocks? And a 2-stroke diesel... What were they thinking when they built this!!?
That they want something to tow m1 Abrahms tanks up mountains and through mud... These have no differentials, they're solid axles.

Glad there wasn't a heavy load on the trailer.
With load it would propably come up just fine with no problems at all.
I think the right tires are on soft mud . If he drove in center . Looks like more compacted
Not trying to be a smartass but,
Why don't you have mud chain's?
THAT'S HOW WE ROLL HERE!
That truck is amazing. One of my favorites
Imagine what a set of chains would do
aint this beast have a diff lockers?
No diff lock on these? At one point 4 of 8 tires were spinning.
For all of the people commenting about the diff locks, he clearly had them engaged on his initial pass, it still didn’t work.
So many people saying “I’ve driven one stop being an idiot” trying to talk themselves up.
Galapagos het can drive just fine the tractor is just a dog, and you all know it.
Why are diff locks not working on the front axle, that is the main problem, no front wheel drive.
Look at the angle of the water in the tank on the trailer. I didn’t think it would make it up the hill. The axles must be open or limited slip. I have wondered why they don’t use all wheel drive semi tractors on the roads in Alaska as shown on Ice Road Truckers.
Heck by the time he gets to the top of the hill he'll be outta fuel the way he's standing on the accelerator
OMG....are you travelling by Amazônia ways with this truck?
IN these locations there ought be some gravel laid down when conditions are optimal
Sure, but how much gravel? Thousands of meters?
We tried that.
They swept up, shoveled, and stole the gravel.
We used sand bags to divert the water.
They cut, dumped, and stole the bags ...

Been stuck many a times in that truck and I can tell you this guy doesn’t know what he’s doing.
what'd he do wrong? Seems like he's over-reving it.
Neither do you obviously! I’ve never been stuck in one of these trucks.
Under them conditions he should have been chained up before he left the high grade.
@@mardievanbree8795 Chains wouldn't have been necessary at all for that terrain,and there wasn't any cargo on the trailer either,so it's just the rig and trailer that play the weight.The real issue is the driver who is inexperienced,those 15 Ton HET's all come with locks,and some versions are different than others,like having cross locks,power dividers,etc.But they all are beasts if you know what you're doing,both HEMTT's and HET's alike,just like MK's and MKR's are built for terrain like this.If there was ice or sleet,then I could see chains being effective because of barley to no grip on the tires.
@@Slim_Slid you just showed your experience level. Out in the oil patch (drilling for oil and gas, or fracking for some reason i felt the need to have to spell it out for you) we chain up daily for the same terrain. He could have used his johnny bar to to keep trailer tucked in high and straight behind him instead of letting trailer drift on him
tire failure - i learned in snow if you have a thread pattern that can not clean itself you will fail. there needs to be groves that let the mud out of the treads.
Should have dumped tire pressure BEFORE hitting the slippery slope
"Dump tyre pressure"???...Wrong, TOTALLY WRONG...Air down in "bottomless mud", but maintain higher air pressures where there is a solid base beneath the mud (as is in the roadway in this vid).
3 sets of tire chains should do the trick
@@whitestacks5762 I've never seen anyone use chains for mud except for snow.
@@Slim_Slid The military does it.

If you look closely at the tires on the trailer just before he stops they aren't turning. Brakes locked up or one for some reason.
No diff lcoks???
This machine is made to carry Abraham tanks at a max speed of 45mph. The car will only perform as good as the driver is. In this case someone drag him out of that vehicle before I loose my mind!
Rev then release slowly to match the torque and power, the truck will trot up slowly. Works like magic
why u didnt block differencial?
no diff lock on this thing?
has, but is not activated
The best part of watching these is the comments..Always someone out there who could have done better !
I agree. Too many have been there and done it all :)
Nah, no components would be overheating just spinning drive train with no load, should of dropped tires air pressure considerably,
Transmission Fluid more than likely needed to be checked after making that Silver 92 scream.
@@Slim_Slid For that transmission, this was really a walk in the park. There's virtually no load on the drive train here in comparison to steeper hills with a heavy load and good traction. If I recall, the military requires the truck to be capable of pulling a load at very low speed (worst condition for overheating) that requires running at full throttle and to be able to do so for an hour on a 100-degree day without any appreciable increase in operating temperature. This truck was definitely just loafing compared to what it is capable of.
@@ericl2969 Your wrong on a few things.
Just because a truck has to move something at low speed does not necessarily mean to run it at full RPM.
Giving it that much Throttle non stop will overheat both Engine and Transmission,this is common sense,not rocket science.
The M1070 used a DD-92 Detroit making 550 HP & 1,996 lbs of Torque while other 15 Ton Variants from Oshkosh made 500 HP & 1,470 lbs of Torque from a 8V-92.The HET uses a CLT-754 Allison Automatic with a TC-496 Torque Convertor.Now,the Military has the M1070A1 with the C18 from Caterpillar that makes 800 HP & 4,000 lbs of Torque,with a 4800SP Transmission.If a M1070A1 still has a CLT-754,then that means it originally was a M1070 with a Detroit before being Rebuilt with a Caterpillar.
The M1070 HET is rated for 45 to 50 MPH only,so there is a reason on instruction for low speed which you are trying to describe.
Aside from RPM and human error,it depends on Transmission,Transfer Case,and 8×8 to know how to move Weight with a Oshkosh.Depending on Gear,Range on the T Case,and Low/High on 8×8,is how you move,regardless at what MPH you are moving at,and if you are not going nowhere at high RPM,then you are the problem.The M1070 & M1070A1 both also have CTIS (Command Tire Inflation System) on the 1600×20 Tires which allows them to Deflate/Inflate depending on what Terrain or Situation you are in,so that adds a bonus for Off-Roading in a 15 Ton Truck.The Heavy Equipment Tractor is actually rated for 230K lbs,but being risque with one of these will expose their weak spots,they bend they break like anything else on this world.In the Army,they use up to 170K lbs most of the time on them with a M1000 Trailer and they usually will haul Abrams Tanks and M109 Tracked Howitzers most of the time.
@@Slim_Slid What I tried to make clear is that the truck is specifically designed to be capable of running at full-throttle and high load demands under the most extreme conditions the Army could come up with for testing purposes -- and to do so without overheating. This situation really wasn't that bad in comparison. Even if the engine was maxed out on revs, which it probably was, it wasn't actually working that hard because conditions were so slippery, so since generation of heat within the transmission is mainly a function of the work load, this just wasn't that severe of a situation. Was the driver being an idiot? Probably. Was it hurting the truck? I seriously doubt it. Not when you consider the incredibly severe driving conditions under which the truck is required (by the Army) to be able to tolerate.
@@ericl2969 Which I literally just explained in my previous comment.
Man I love these OshKosh trucks fucking built tough as shit. Even for drivers like this one. I wonder how the internals are holding up after this.

Who needs to use the diff lock anyways?
So this 8x8 truck have no diff lockers?
Strange.
All M1070 HET's come with differential locks,the 1993-2003 Variants had Interaxle Locks which acted as in one set of wheels would move slower than any other one if the rig got stuck in somewhere.If it didn't have locks,then hauling a Abrams Tank out in the sands would be more of a pain in the ass.
It aint about being all wheel drive. Its about having the right tire pressure (should be very low), mud chains and diff locks all around.
This is 100% a decepticon
Why are the wheels not locked with a differential lock?
Dang I was also stepping on the gas pedal my self...
Is the point to till the road so no other trucks may pass?
TH-cam BACK OFF WITH ALL THE DAMN ADS SHIT SOME ARE LONGER THAN THE VIDEO IM WATCHING.

That's for tank transport
According to local lore, he's still trying to drive a tank with liquid poop up that mountain.
Amazing vehicle and ya you can see when he locks his diff's I had an older Toyota I had to get out and lock the diff's and that little truck pulled a few full sized ford's out of mudholes. But it was the 1400 bucks I spent on tires that did it. Loved that truck.
I had a '74 Toyota Land Cruiser. It too had locking hubs. A guy told me he hated them because he got tired of getting stuck in the mud, having to get out to lock the hubs and getting all muddy. I told him i never got muddy, would lock them in Before off roading. He looked at me dumbstruck ...
If they are making all this noise in a hostile country, the enemy will hear them and they won't last very long
The Air cover ensures the transportation folks can be noisy
Now that’s a hell of a driver
sounds like it has a Detroit under the hood
Detroit 8v92
I thought so
More than likely a DD-92 (DDEC/Electrical) other than 8V-92 (Mechanical).Most M1070 HET's run DD-92's with 500 HP and 1,996 Torque.The recent or rebuilt 1070's now run a C18 6NZ Caterpillar with only 500 HP and 1,470 Torque.
Is that tote on the back spare fuel to get up the hill?
