I pulled the deuce out the other day when it warmed up , and discovered how bad this thing is in the snow . a little shoveling and away we went.

The oddest thing about them is that they were only 6 wheel drive in forward. If you got stuck going forward, trying to back out was usually pretty pointless. Also, if you ride her too rough in forward, you can tear the sprag clutch out of the transfer case, which is what provides the automatic engagement of the front axle.

Apparently the dual wheels also do not help, but rather make the trail blazing worse. I have operated some of these with the later good year tires on them. like the MLVW initially had. They sure added to the cross country performance, as well as to the safety on icy roads compared to the non directional suicide tires.

Very nice and clean looking truck. Were the duals added on post military? Or was the cargo box salvaged from elsewhere? I ask because I thought the M211 had a flat bottom box, with no wheel wells.

I have been considering picking up one of the old dueces, but at present can't decide between the old duece or one of the MLVWs when they become available.

yes this is actually an old mechanic service truck , but when i got it it had this box on it so i left it that way. Seems to be a pretty reliable truck.
Im thinking the farmer i got it from had the reverse sprag linkage disconnected if that sounds right . the linkage ran from the shifter back to the transfere case i do believe it would give you full 4x4.

There is no linkage for the front axle engagement....it will kick in when a certain amount of slippage occurs between the front axle and the rear axles. If memory serves it was 4 or 10%. When the rear axles are trying to over run the front axles, the sprag automatically engages.

To test if the front sprag clutch is working, you only have to jack up one front wheel. You should then be able to turn the driveshaft one way (as if to back up), but if you go the other way the shaft will lock up. If the shaft will turn freely in both directions then the sprag clutch is buggered.

Both rear axles should be engaged all the time. If you lift one wheel and try to turn it, it should not turn. You would have to lift a wheel on each rear axle to be able to rotate the wheels. If you can rotate with only one wheel raised, then you have a problem. It could be a broken axle shaft, or a broken differential. These were quite common on these trucks when I used to work on them. A trip as delicate as a road test could result in a broken diff.

the linkage that was unhooked moves something on the transfere case only in reverse , so i figure he unhooked it to modify some operation of the reverse sprag.

Rob I have had M211 & M135 at present I own 2 MLVWs and I much prefer the ML. I hope to have a new serial number for my MLVWs in the very near future and if I do then I will be road legal. My main ML is great, it sits outside in the snowbank and when I need it, jump in it and she fires right up.
I know the old M series are great but parts are getting very hard to find and they are getting pricey. To date apart from regular maintenance, oil filters etc my MLs have cost me $0. I am happy. Gilles

This Spring was very wet , this side fell right in it.
I had to shovel a bit then the ford deisel pulled very hard.
