Couple m911 questions

[DEMON]

Couple quicky questions for the green iron noob here.


Anyone know the curb weight of an m911 tractor?

Is the lug patteren 10on285mm or 10on11.25" ?

Any idea what the diff gear ratio is?

What the difference between m911 and m920?

Thanks for any insight.

gross vehicle weight 88,000 lbs. rated

diff ratio irrc is 6.21

there are a few differences between the 920 and the 911 beyond shear size comparison.

Hey, I got the gvw on the data plate there still. But I'm wondering about the curb weight. What does it weigh just sitting there.

So the 920 is bigger or smaller?

 

[NSCoyote]

m911 is 33K and change If i recall correctly, the 920 is smaller and more road friendly albeit lighter and less payload capacity.

if ya dont mind me asking are you looking at aquiring one or the other or for your own reference?


M911 weight 39,951 lbs

M911 is overwidth with duals on. M911 has an air operated throttle meaning that unless you have air pressure you have no throttle. If the M911 sits for a while and looses pressure prime in the fuel system you have to re-pressurize it before it will run (it will start but will drain out the fuel filter and not have the air pressure to re-prime). Re-priming is very easy to do however, done it many times recently.

The m911 is a beast !! with dual rear winches. The m920 is concidered a medium duty with a single winch and you don't need a wide load permit for it.The m920 is no sloutch weighing in at over 31000 lbs .

M911: Oversize Permits EVERY TIME YOU DRIVE IT on the public roadways.

M920: Basically "street legal"

But the testosterone factor of the M911 is way cool

Someone abandoned an m911 at our shop after we overhauled the engine last year. So the company is looking to sell it to recover the bill. So I'm eyeballing to scoop it up.

If I super single it might bring the rear width down to legal. I think 8' 4" is max width around here. I'll measure it at work tommorrow.

Nice!!!

 

[rorybellows]

im waiting for the releasal of the 1070. throw a 18 speed and some more road friendly tires, and you got one helluva heavy hauler

 

[NSCoyote]

Demon, PM sent about that abandoned M911

 

[indy4x4fab]

DEMON, nice to see u on the greener side of thing, . You got to save it, its like a lost puppy dog, dont let it go to the scrap yard like, like a hintz 57 pup going to the pound.

Couple more shots of it for kicks. The 5th wheel plate is higher than a standard truck for sure, but its equal to modern heavy haul trucks here's a newer Freightliner Columbia 1st pic. And an older Kenworth c500 2nd pic.

Different Pin size...

The biggest issue with M911 is fuel mileage and tire availability.

 

[DEMON]

I understand the military pin vs civilian. Was just noting, as someone I recalled was having trouble with standard trailers on one. But all the oilfield haulers I'm around have trailers that work. Some have risers built into the suspension mounts. Some have necks that double pivot too. I'll try to find some pics of the winch trucks doing a rig move with the live rolls pulling skids.

I know what your referring to as I'm familiar with the industry. But most truckers prefer a level or near level deck. The C500 with a standard trailer looks like a ramp.

True true, ski jump. that double pivot neck is nice for flattening that.
