M931 Deuce Bed Install

Last pic is where the bed was sat when I picked it up. It looked alot easier to raise the bed over the tcase instead of notching it. Added 2 2x4s on each side to raise it up. Ended up cutting the stack just under the cab and removing the bracket. The bed was pretty simple once everything was out of the way, I welded some 3x3x1/4 angle to the bed for new brackets and bolted everything down with new grade 8 hardware. I ran the exhaust straight out the back for now ( until I find a suitable 90 to either dump down or to the side ). Welded up a few hangers under the bed and buttoned everything up. Even re-used the factory heat shield. Theres about 6" between the shield and tire, after I drove around for about 30 mins I could still touch the heat shield.

Will post a few more pics as soon as I get some time to get the bed painted ( weather permitting, I wanted to do it tomorrow )

Looks good. I like the short look the deuce bed gives them. Guess you got the bug taken care of on the fuel issue hopefully.

Thanks! Yes it ended up being the fuel filters and lift pump. Picked one up at cummins atlantic. Going to replace all the fuel lines here soon just for peace of mind

Good. Glad it was a cheap fix.

Thanks for sharing. Just picked up a few of these and think we're going to do something like that with at least one of them.

That looks pretty cool!

Very nice! Similar to what I did with my M52A2....

A few pics from today. Got her sanded down, primed and painted. I should have taken the hardware off the bed before paint but I was in a hurry, oh well, theres always later.

Lookin good! I can't decide, if I want to put a deuce bed on this other truck or if I want to bob it... I think I told you the guy backed out on it, I think his wife put the smackdown on him...

LoL!! Bob it with the deuce bed and weld the 105 wheel wells in it

looking good.... here is another option for the exhaust.

It is a bit loud and an you have to worn the Passenger to watch for the hot pipe.. but gets some attention.

Looks good. Do you worrie about the bed walking a little sideways if the bolts get loose. The way it is now looks like the bed could shift a bit with that large of a gap on the hold down. I might have extended the last two angle iron bracketts all the way down to rest on the angle that is mounted to the frame. Then put the spring between the front to take up twist on the frame just like it was on the Deuce frame.

The front actually sits inside of the bracket that raises up over the tcase. It is almost a perfect fit. I forgot to post pics but on the inside of the bed at the rear I welded in 2 pieces of flat bar straight down to keep the bed centered. I am thinking of adding one more on each outside just past your rear most red line just past the angle bolted on the frame.

Tornadogt, after my M54, I dont think I could own another straight piped truck at the cab, LOL. The stack was cut off after this pic just above the cab. Its so nice being able to hold a conversation finally.

Also a Well Built truck.... Your right on not having much of a Conversation with straight a pipe, mostly you scream at each other and use hand signals but smiles all around (at least for the first 20 mins or so)..

Did running the exhaust out the back make it a lot quieter than behind the cab? I might be tempted to move the bed forward on my M925 and ditch the stack and tire carrier.

I wish deuce beds were easier to find in good shape, M105's are just so much easier to find in good shape for cheap.

Very true, but it looks so good. I may end up with a stack eventually ( depending on fumes in the cab ) But will likely go with a 5" straight through muffler and aussie cut 5" tip

Yes its pretty quiet, most of the noise is motor related. Tomorrow I'll be rhino lining the bed and starting to strip the interior. Not sure whether I want to rhino line the floor or just paint it. But I will be dynomatting either way to try and cut the noise down more.

Why not just shorten the 5-ton bed?

After looking at it, if I were to do anything to my 925 moving the bed forward would not be worth the time/effort. I guess doing a crew cab or extended cab would make more sense. The m932 I have I want to either Bob it with a m105 bed, or leave it 6x6 with a deuce bed. I bought a pristine deuce bed (for a pristine price) but not sure I want to use it on the m932 when I have a nice condition m105 I paid less for.

I have a 12' dropside bed on my M931A2 behind the knuckleboom. Pretty happy with the fit, a little more overhang, but really not that bad...about the same distance a deuce bed is behind the rear tires. I have it hinged and a cylinder mounted, just need to get a power beyond valve to mount. Meantime I can lift it with the k-boom if needed. The 5 ton dropside has the front section that varies from the deuce beds even though the folding sides are the same length. Also- very happy with having a full 12' for all logs I can grab with the grapple I built on the end of the knuckleboom.
