Deuce/5 Ton Interchangeability

[Rebelpride]

I have a 5 ton dump that I bought before I deployed. My dad says that he doesn't think that it will start and that I should part it out, but I am not giving up hope yet as I have not even seen it in person. But my question is: If I cannot get it to run could I take the dump bed and lift assembly and mount it to a deuce frame without any issues. Also is it possible to mount a 5 ton fifth wheel to a deuce frame without problems?

the 5th wheel will not be a big deal, the dump will mount BUT I would look at the WEIGHT

i would think the weight of the dump bed may be to heavy for the deuce

I'm going to assume you mean an M817 dump.
The dump bed assembly weighs about 3600# empty. It would be like driving around loaded all the time.

With a standard payload of only 5000#, that would mean you could only carry 1400# of stuff.

The dump bed assembly also raises the center of gravity, so body roll would be more of an issue with the deuce springs.

The fifth wheel hitch seems like it would be pretty simple, as long as you didn't try to tow too much trailer, or load. The deuce tractor, M275A2, has a payload of 17000#.

Edit: On second thought, I forgot to remove the weight of the deuce bed, about 1300#+/-, I think? You would have a payload capacity of 2700# for stuff.

The dump bed will fit but the PTO drive for the pump is on the wrong side of the trans. You'll have to come up with an alternate way to power the pump. Ive seen one done with using a small gas engine mounted behind the cab to power the pump.

The 2 1/2 ton is for offroad. My data plate basicly says on road is double. I thought the same was true fro the 5tons, so on road would be 10 tons. Am I wrong?

I asked this same question awhile back. Seems there are several that have put a M817 bed on a deuce with ok results. The pump drive can be solved with a simple chain and sprocket setup.

but the capacity of the deuce on road is a very conservative 10,000 lbs. i don't follow your math?

You're right. I was stuck in "deuce and a half" meaning 2 1/2 ton thinking.
2 1/2 ton is cross country, 5 ton on road.

The payload capacities appear to be the same for the M342A2, which is the M44 version of a dump, and the M35A2.

I don't know if the M342A2 dump bed is the same as the M817 (other than the pto difference) but if it is, and the M342A2 chassis is the same as the M35A2, then I guess there is no real reason the OP can't put the dump bed on his deuce. The PTO problem shouldn't be that hard to overcome. The hardest part would be finding the PTO, for the deuce transmission, that has the front and rear output shafts.

If you don't have a winch you would not need the front and rear outputs, unless i'm wrong, the deuce PTO can be mounted with the shaft either way.

I think it would be a heck of a lot simpler to get the M817 running... those Cummins NHC205s are simple and tough as nails.

I think you're wrong. I tried to "flip" the output on a PTO and came to the conclusion that it can't be done. I tore the sucker apart and put it back together several times and even tried to use some parts out of a 5-ton PTO. It looks like it will work on paper but in the end it won't work. With the right combination of 2.5 ton and 5-ton PTO parts you can get it put together coming out the rear but the output shaft is almost right against the master cylinder bracket (no way to attach any sort of driveshaft).

Well the original game plan is to get the 817 running and driving. I have not seen it in person since I bought and am just going off of what my dad has told me. The engine looks complete, the body has some cosmetic damage, and the interior needs seats and a light switch and it is missing the pto.
