1998 F-800 weight

[zlock24]

Does any body know what a 1998 Ford 4x4 F-800 8.3 cummins diesel with an 11ft dump body would weigh empty? I'm trying to figure out how much weight the 4x4 adds over a regular 2wd medium duty diesel truck.

My IH 4800 4x4 DT466 with a 12 foot dump bed weighed a little over 16,000 pounds.
If my truck was 2WD, it would have weighed ~14,000.
I would say the extra divorced transfer case, front prop shaft and live front axle adds about 1,500-2,000 pounds.

That F800 probably weighs 15,500-16,000 pounds.

Im a huge 8.3 Cummins fan, but if you are still looking for a big 4x4, you will like the IH better. They are usually built with a straight through frame, where the Ford will have a cut & stacked frame, which raises cab height considerably. DT466 is almost every bit as good as an 8.3 but the 8.3 has the extra displacement- a real fine Diesel engine.

My gas truck weighs 11,700. Most of the diesel trucks with 10’ beds are around 14-16k. It wouldn’t surprise me if that truck tops 20.

Personally if I was buying a diesel dump I’d want a M11 Cummins or something else above 300 hp with a 10 speed behind it.

Ever see how nose high those trucks are with bigger displacement diesels? They get top heavy and ponderous. An M11 needs a frame cut and stacked adding 10-12 more height to clear front axle. Not crazy about cut frames.
Although you dont get the displacement, with a 466 or 8.3 you can get 300HP and over 800TQ. An M11 is better suited for a tandem dump or road tractor engine.
For a 6 wheel truck, and 8.3 or a DT466 with a higher rating is plenty of engine for the job.
Heres my 4800 4x4 with 12 foot dump. She weighs 16,000 + empty. It was 250HP stock. I tweaked the pump and added a 300HP turbo from a wreck. She was a real runner. Didnt have too much reverse rake to it. The truck looked level.

Im looking at 6x6’s now and I may be in a DT466/530/570 pre emissions with an automatic. After having driven these trucks, I find when the terrain gets slippery, an automatic doesnt lose power or traction like a balky manual. Just that one time you cant find a gear in the mud and it’s all over. Thats why front discharge concrete mixers have them. They dont get stuck as easy because you dont have to shift while avoiding getting stuck.
Post mid 90’s allison autos are tough and they will flat out scoot past a manual.

There aren’t many big motor single axel dumps to be had at any price. But you can buy pretty clean road tractors with big motors for $5000. I was thinking about buying one and putting a dump on it.

Yeah but not 4 wheel drive :laughing:
Youll spend $30,000 or more for a decent used 4x

I found a 7400 6x6 for 35000 and it was gone in days.

Lots of guys buy single axle road tractors and put a 10’ dump on them. Gives you a tractor package, too :thumbsup:

I wasn’t looking for a 4x4. I’d buy a military 6x6 if I wanted that. A medium duty single axel is about the worst off-roading truck you can get. I’ve seen tandems with lockers going off road far better than my single axel could do. I don’t have enough power to drive through soft ground either. Here’s a good candidate for my dump truck swap, air brakes, M11 Cummins, 10 speed and heavy duty.

Id want the AC and superior seating options on a non military, but that’s cool. Different strokes for different folks.
The military 6x6’s are pretty low on power, too.
Never felt like they had much GVWR, either, even though theyre overbuilt.
Now if it were staying on the farm? Military would be suitable.

Straying pretty far from OP topic, too. :laughing:

Yeah, I’m not a big fan of those trucks. It’s too bad cement trucks are rear engine. That doesn’t leave room for much repurposing. The cabs aren’t the definition of luxury either.

To kinda continue the topic, how much worse is the turning radius of a medium duty 4x4 compared to its 2wd counterpart?

Also I never realized how much lower to the ground a factory 4x4 international is compared to a conversion Ford. Thanks for sharing the pictures Hay Dude.

The only reason I'm really considering this is because I found a screaming deal on the 4x4 F-800. It only has 40,000 miles and the local PSD is selling it for $8500.

I’ve never drove a 4x4 medium duty but my 2wd 6500 will flat turn. It’ll turn the same radius my suburban would.

Turning radius in THAT truck is bigger. IH seemed to be more reasonable, but still more than a 4x2. (When I was buying, I also looked at an F-800, too). I also worked for a guy who had one and I drove it for many years.
What I gained with my big 4x4 in off road capabilities, I gave back in on road turning radius, visibility and handling.
What you really need to be thinking about is repairs. That front axle can be very expensive to upkeep. I wouldnt be surprised if it needs ball joints. I did them on mine and it was costly. Also look for steering play.
The transfer cases tend to drip. Look underneath for leaks.

Look at the back of the cab where the frame goes underneath. If the cab sits about a foot over the frame, it has a cut frame. IH engineers their trucks in the factory to be a 4WD. Someone like Ford will send their trucks to Marmon Herrington to be converted from 4x2 to 4x4. They will cut the frame and stack it. I never much cared for that. Now some IH trucks have a stacked frame. Those are usually in the really big displacement diesels because the engine is too tall (or hangs too low) to clear the straight through front axle) OR the truck was a 4x2 and was sent in to be converted AFTER it was built.
I guess there’s a chance Ford will start building them in the factory with a straight through frame, but when I was looking, they did not. Freightliner is another option and their older trucks had the 8.3L option.

If you want a big 4x4, IH with DT power is the way to go. I know the 8.3L Cummins is a real sweet engine, but the DT 466/530 is pretty close. My perfect truck would be a IH 7600 with an 8.3L at 330HP Allison MD 3560 and a straight through frame.

My Canadian cousin cut off the sleeper of a road tractor, which gave him enough room for a grain box. Riveted a new sheet of aluminium on the back of the daycab and there it was.

Here in Europe you dont have such deep sleeper cabs, so road tractors arent suitable for conversion without frame extension (which would require a heavy dump subframe, or an inner chassis liner
