Stovebolt.com Forums The Parking Lot Tons 'o Fun 49 3800 Dumpbox

Someone brought me another jewel to work on

I need to confirm it’s a 49

3800

Single rear wheel

Step side box that dumps (well it doesn’t yet nor does it run)

Could you order a dumping box from the factory?

Thanks

Jack,

Got any pictures of it? I think it'll be helpful to identify it.

Yup.

Looking forward too seeing.

Now, there’s another jewel, alright !
I love the flared box sides.
The belt hydraulic pump is a real direct approach.
I wonder if the box was designed for sugar beets?

Sugar beets is a good guess

Can’t figure out where it’s from by markings on the door

I’m in northern Illinois

When I saw belt driven pump I thought aftermarket

Thought factory would be driven off trans

The belt driven pump with the big activation knob poking through the dash looks exactly like the one my 1948 3800 has. My dump box, however, is a single hoist and the box is ready made, completely, somewhere in the US I suppose. It was designed to have the stock fenders mounted on the aftermarket box. There is a manufactures tag on the outside LF corner of the all steel bed.

That's all for now and hope this helps somehow..

Second response:

The seller said some older Uncle had passed on and the 48 made it to him. His story, as told to him, was this PU was ordered with No bed and when it arrived in eastern MT, the rear fenders were strapped to the frame. The Chevy dealership installed the dump box on it. It was used for grain hauling.

That is all I know.

That is interesting

This box is 9’

Figured out it’s a local truck

MONROE CENTER IIL (as Illinois used to be abbreviated) so no sugar beets

Maybe used for ear corn?

Cool stuff!

I’ll see if I can find an ID on the box

So Jack, did you get the "truck to work on" from 4D8PU?

Is that info on the door what it looks like -- it is this "Rt 1" ... ?

After closer examination actually someone else saw it the lettering is MONROE CENTER IIL

As far back as I know history a car dealer Jack Wolf got it

Jack was in to old cars

A friend of mine bought it

Any leads on options for that year

Was the 9’ box available or custom?

The 9' bed was standard on the 3804 models. Looks like the flared sides are add-ons. The dumping mechanism is also add-on/after market.

Thank you

Jack -- You bet. Here are some photos that might help -- these show how the bed looks on all 3804's, and how your truck would have looked, coming out of the factory. Also, it was fixed to the frame -- no hoist mechanism.

Anything beyond this configuration (as on your truck) was added at some point after it left the factory. Unless you have some documentation, it will be very hard to say for sure if this was a dealer add on or a post-sale upfit that the truck owner did at some point. Your add-ons look professionally done and not farm shop "agri-engineered."

There might be some literature floating around out there for that company. There were a lot of companies, most regional, that offered up-fits like that.

Thank you!

Anyone know the dimensions for the wood for the floor of the bed

Width of plank

Thickness of the plank

Dims of edges where steel strips hold them down

Thanks

Widths varied. Use the position of the bolts/holes in the cross sills. There would have been 9 boards on your truck. The boards would be a nominal 3/4" thick.

Here [gmcpauls.com] is some info on bed wood, including the dimensions for where the steel strips go.

Thank you

Got it running

Hoist works!

Jack,

That's great news!

We need PICTURES my friend - haha!!!

Don't keep us in suspense, please.

I need an education about the box inside the engine bay mounted where the brake MC is found. I see a rubber hose going into it.

Is that for some type of vacuum assist ? Curious minds want to know.

Nice truck.

Possibly a hydraulic fluid reservoir for dump cylinders.

I have a '50 L134 (3800) Canadian truck with a dump box as well. My box lift system looks like the same as yours except my hydraulic pump is PTO driven off the transmission. You have a nice truck.
