New (used) IH 7500 Dump Truck purchase, modification & fix up

[Hay Dude]

After a lot of looking around for a dump truck, I finally found pretty much what was wanted.
Must haves were
1. 4x4 chassis
2. Heavy specs (>35K GVWR)
3. Higher than typical HP/TQ
4. 3 stage engine brakes
5. Automatic trans
6. Single thick frame-not double.

I hit on the first 5, but not 6.

2007 IH 7500 4x4, 41,000 GVWR, HT570 (310/1050) with 3 stage brake, Allison Rugged Duty series, double frame.

Just got here today and didnt have a lot of time to go through it. It has a wing plow frame and a stainless steel dump with a live floor salter system and spinner.
I have no use for the salting equipment and would prefer to sell everything off the truck and install a standard 12’ steel dump box.

Good find ! That live body sounds like just the thing for your winter sanding but it is a trade off for your summer uses .

I really don’t want to go into salting, but it is tempting….

Would rather just have a plain old HD steel dump body.

It's still a nice truck. If I remember correctly, you've been wanting it for quite some time.

I am still hunting a large flatbed for square bales. The Ram & gooseneck have been doing extremely well, so I will wait until the right fit comes along.

Nice find.

Nice heavy duty truck, that's some serious GVW for a 6 wheeler. Reminds us what the truck is for. I seem to recall you want it for hay delivery but a 12' bed wont haul much. If you are going into the rock hauling business then that rig is a dandy.

I worked for NSDOT for 32 years, 25 of those in the welding shop. Seeing the damage salt, brine and calcium chloride does to equipment along with no undercoating, you couldn't pay me enough to put a piece of my equipment thru that.
As for the double frame, that is the only bad thing I see about that setup, the way the rust spreads them apart is unreal. They finally went with single frames the last few years I was there.
Is that an Everest S/S body? You could sell that and the wing gear and get a nice steel body for what you'd get provided the chain and under tray is in good shape. How 'bout the spreader controls? If you're not going to use them, you'd be able to flog that too...

1. The trucks was undercoated pretty good, but that has begun to peel off and there’s surface rust. It came from a municipality originally and it appears they took very good care of it. The cab sheetmetal is surprisingly good, too. I didn't like the double frame, either, but it hasn’t swelled or separated and a truck like this is a unicorn. Took 2 years of searching to find one with these specs and features.

2. Its a Tarrant/Tarco body. Really nice. Everything looks to be in good shape. Honestly, I’ve only had about 15 minutes to look it over because we are swamped with hay & property work.

You are exactly right on the body swap. I plan to sell the whole set-up and parlay the money into a new 12’ steel dump bed. I would like to clean & paint the frame and fix things while it’s just a chassis, too. No use for the control tower for the wing plows and the large hydraulic tank.

Had one offer of $11,000 for bed & salt equipment. Would like to get $15,000 if possible.

No substantial rock hauling. I have a property maintenance/construction business, too.
We have a lot of ditching work where 4WD will be great. Also plan to use it for hauling soil for top dressing my hay fields. Could also buy a 25’ trailer & use it as a backup hay hauler.
Plenty of uses.

How much is the new body ? Wonder if a truck upfitter would be interested in working a swap?

 

[workinonit]

You can pick those type trucks up at the auctions around home for a song. I just saw a couple sold last Saturday. Of course they are all plain dump bodies. No salt in SC.

Really?
Show me a class 8 4x4 dump with over 300HP & automatic for ”a song”.

There’s a guy nearby that’s pretty reasonable and has done dump bodies for me in the past that might be interested in this one. That would be the easiest way to do it.
Will be looking for 12’ body soon. I have a couple body companies around here I can work with. I would think 20k + for new with hoist & installation. Prices from inflation are so high now that nothing would surprise me.
Removing this one won’t be super easy. Lots of hydraulics to disconnect & cap-off. Plenty of rusty nuts & bolts to break free.

For a S/S body in good shape and the plow gear it's well worth it. Get rid of the front drive pump (i assume its a variable displacement piston pump?) as well and go with a conventional pto pump as long as the trans is set up to run it. It would allow you to get rid of the cow catcher on the front and a far sight cheaper when it breaks down.

How much is the new body ?

Guessing, I'd say a new S/S spreader body now days would be worth CAN$ 40K+ at least. Last time I was involved with purchasing, a conventional 14yd steel body with cylinder and tip hinge was CAN$22K, no install. The hydraulics to run the plow, wing, salt and dump body was CAN $22K

Wonder if a truck upfitter would be interested in working a swap?

You'd have to find one with a sale for it so it wouldn't be hanging around, it'd be a lot of $$$ to keep on spec.

Pretty much my plan.
I was thinking about keeping the pump, but it does run off the engine via PTO shaft.
Its all kind of up in the air right now. I don‘t know if the allison has a PTO provision feature. Would think it wouldnt since theres a engine driven pump, but I will find out. Havent even had the truck 24 hours yet and worked past dark last night.

I just want a heavy 12’ steel dump with a thick floor and an air tailgate.

 

[Hay Dude]

Trying to put together an initial list of fix ups and repairs.
One thing I know is the truck needs an exhaust manifold gasket. I would also like to replace the rims as they look pretty nasty.

Next week is PA truck inspection. That will reveal a lot.

I'll let you know. Heavy equipment sales are usually once a month at home or in Georgia. Next farm sale is in Feb. They always have some trucks.

If it's a load sense pump, don't forget you'll need a closed center valve with the extra plumbing of the load sense lines. As well, if it's electric over there's the expense of the electronic controls.

Worst thing about those, if the drive shaft decides to head south, it usually takes the rad with it. Or when the joints start wearing out, it'll beat the harmonic balancer up. You've also got the hydraulic hoses running under the engine/transmission which depending on how they've been run can be awkward to work around. Not only that but changing belts is a royal PIA.

Me, if I were gearing up a dump truck, I'd go for a pto pump and either air over or cable controls. The acronym KISS plays in my mind .
Be sure to let us know what the outcome is

1. Yep they’re hangin down.

2. Agree 100%. I had an older version of this truck, an IH4800. Had a simple 7 speed manual trans with PTO driven hydraulic pump and a reservoir for hydraulic fluid. Very simple.
I’d like to sell off the complexity of this system and trade it for the simplicity of a 12’ PTO driven dump.
