Answered in the other thread on my steering problems, to keep that problem and its solutions in one thread.

I did not drive this truck more than 75 miles (less than 100 km) between 2010 and 2012, when I made it street legal. Since 2012, I drove with it about 1 (ONE) miles in the meadows. Probably most of the wear had already occurred before I got the truck. I changed the oil shortly after I got...

Rustystud, gearbox is out and I found the big problem. Frank8003, nice articles. See also this a bit older video on steering

Got the steering gear box out and inspected. At left, the box looking inside. The housing for the spline is still attached. At right the housing removed and detail of the splines of the steering shaft. Everything moves very smooth, without obstruction, buttt ..... The stud assembly...

I tried to figure out how the Ross Hydrpower HP70 works, especially how the turning of the steering wheel is transferred into moving the lever that regulated the oil flow. When searching, came across an old military movie explaining it all, if even a bit long winded...

I always wondered why all 5-tons are "post Vietnam"; the M39s and most of the M809s are definitely Vietnam area trucks. Probably, in the early days of the site, it seemed the easiest solution. In addition, with time passing, search results in the 5-ton section are more and more dominated by...

I have to find me a truck or bring one over to join the convoy provided we make a night stop in Mile 422 Toad River Lodge. Spent 6 months there in 1981, high time to get some fresh coffee there. About two hours further on the road are the Liard hot springs, also a very relaxing stop, especially...

I thought it would be this one, but am checking with some Danish to see if we missed something. Reomie actually is in the Netherlands. The octogenarian owner is doing US trucks, his older brother in the north of the Netherlands is doing the more modern NATO Dutch and German trucks.

In the Netherlands and the Czech Republic, I got away, but that was in a private car. Trucks are treated less lenient. All the other stuff always is in the car, but sometimes I find that my spare bulbs are out or kaput as well. To be clear, "stay where it is" in Europe means: a safe spot the...

Easier said than done. The nearest scrapyard is more than 600 miles from here. They are looking for a used set for me, but at most they maybe have a used old Ross HP70, not the newer M809 series. I talked with Dave from Easternsurplus, but shipping costs alone from the USA to the Czech Republic...

When I made the M51A2 street legal, one of the high priority items was the light all around. 1) I had to install new front lights, because the originals were too far to the center relative to the side of the truck. This gives on-comers the impression that the car is smaller than it really is...

Thanks for the warning. I am now in this process, see the last three posts of this thread. Still did not get the Pittman arm off. However, the box is finally free (loosened the drag link instead) and will be going to inspect the gear once we have it inside the shop very carefully. Below a...

Next step done. We did not manage yet to remove the steering wheel from the steering shaft or the Pittman arm from its shaft. Did loosened all the bolts so at least I could turn the gear box and take off the power cylinder casing. To my big surprise (and disappointment) I did not see any clear...

That's a new one for me, never heard it before. Worth a try (if I can get candles here) So I will try with my small burner and some spare fillings, see if those two tricks work.

I tried to remove the Pitmann arm of our M51A2. Earlier I already tried to remove the steering wheel as well. I used two pulling devices, one smaller with two legs, one larger (about 1 1/2 feet long, solid, heavy) with three legs. In all cases, I soaked them in WD several days in front several...

Saw this during our business holiday in Slovakia. Somehow it shouted MV to me, but I am not sure. Does anybody recognize this as a military trailer?

You know those days that everything just goes perfect, everything falls into its place straight away? ... Well, this was not one of them aua Some of the pieces and slivers of steel I took from the steering gearbox. The lager piece at left looks like a part of a bearing or seal cover about...

As starting remark, the system is not leaking oil anywhere, so all outside seals seem to be ok. Started to take down the rest of the steering assembly following TM ...20 and especially TM ..34-2-2, pages 70 to around 150. "Drain the steering gear box". Did anybody ever manage that...

Bump after the GA rally snow-under. Anybody knows what is the manufacturer and type details on the late M39 5-tons replacement steering assembly? Or is it "just" the new 809 series steering? If so, I did not find those specs, any help would be helpful.

The thread includes a lot of good advice, so I will continue here rather than start a new thread. Most important remark: reread your own threads BEFORE you start work again, can help and at least makes you feel less stupid. Since 2014, the truck has not moved much, and the last two years...
