I found a fellow local to me that had a 123 sitting out behind his business and it hadnt run in I dont know how long. One day I asked if he would be interested in selling it and he sold it to me for the scrap price of steel and told me an interesting story about the truck! It was originally purchased by Memphis Equipment when it was released from the US Govt and then it was bought by a company working on the Alaskan pipeline, it had some gigantic post hole digger on the back of the truck and it was used to drill the holes in the ground that the pipeline supports were then mounted into. I hired a buddy with a large wrecker to go pick up the truck and bring it over to my shop and it took me a while changing all the filters cleaning the fuel system out including the tank then had to get batteries for it and after a week or so prepping it I got the engine started, I believe it had 2 or 3 bad injectors that had to be replaced but no big deal. Then came draining everything on the driveline and refilling with new lubes and I did find a set of TMs and a Lube order so I could adequately clean and lube everything in an OK manner. One early Sat. morning I got up early and fired her up and I only had to drive about a half mile to a buddies house out in the country and we drove all over his farm that day the engine ran pretty darned well but did fine a few fuel leaks that I had to fix and all the differential braking air assemblies on the steering column had been somewhat dismantled and plugged. I got a call one day from a fellow that was restoring another 123 and he offered me the right amount of money for mine and it was gone. I must say that I felt very fortunate to have the experience of getting to work on and drive a tractor like this one, I learned a fair amount and had a lot of fun!

M123 with tank trailer m747 I was a recover specialist in the 70,s down memory lane

When I was in Vietnam the ones we had were Cummins 265 HP V8's

I feel like the Army probably had some more comfortable prototypes and they said, hell no. Make it a bone jarring, teeth rattling sweat lodge.

Love the sound tho of those heavy duty v8 engines

Some turbos. That’s what she needs. Front tires are a cool upgraded Enjoy that rig.

I love it how much

Exhaust leak? Lol

Do you want a sell it?

Are these 10 tons multi-fuel?

Cummings V8 non turbo

Didn't these originally have huge Gasoline engines??? Le Roi or something??
