A few quick questions.

1. What is this? It has a wire that goes into the firewall area and under the dash somewhere and another one that drops down back behind the engine, I have a 72 F100 that has been through many owners who have hacked quite a bit 360 motor and 4 speed manual.
Also I am wanting to swap the 1/2 ton rear end with a 3/4 ton rear end, is this going to be a nightmare and worth it? I use the truck for gathering and hauling firewood so I need it to hold the weigh of a cord of wood or more.

Thank you to those who can give any advise!

Adding a photo would be very helpful.

I believe a cord of wood is 4ft x 4ft x 4ft, your 1/2 ton should handle that just fine.

Depends on the wood. A full cord is even with the top of the cab with side boards (actually 4x4x8). I have hauled full cords of birch on my old 72 F-250 and it almost bottomed out the rear springs. It was a light duty 3/4 ton with about 6200 GVW IIRC. Now I burn mostly oak and ash and it is also heavy, sure wouldn't put a full cord of it on a half ton. But nowdays I am lazy and to keep from handling the wood, I have a couple firewood trailers I take to the woods and then just back them up to the house and use the wood right out of the trailer. Much easier than unloading the pickup and re-stacking.

willowbilly3, You are very generous with your measurement. I believe you are in the 2+ cord range. Looks like I was incorrect also. I knew that a cord is a measure.

From Wikipedia, the free encyclopedia


A cord of wood
The cord is a unit of measure of dry volume used in Canada and the United States to measure firewood and pulpwood. A cord is the amount of wood that, when "ranked and well stowed" (arranged so pieces are aligned, parallel, touching and compact), occupies a volume of 128 cubic feet (3.62 m3).[1] This corresponds to a well stacked woodpile 4 feet (122 cm) high, 8 feet (244 cm) long, and 4 feet (122 cm) deep; or any other arrangement of linear measurements that yields the same volume.
The name cord probably comes from the use of a cord or string to measure it.[2]

If you measure a long wide 70s Ford, measure to the top of the cab and deduct for the wheel wells, it comes out real close to 128 cubic feet. Seems like it was 132 minus the wheel wells. I measure width at the inside of the stake pockets where side boards would be. Most people selling wood bring a pickup load (with no sideboards) and sell it as a cord when in reality it is maybe (generously) 2/3 cord. I think that has a lot to do with why most people don't realize how much wood a cord really is.
I used to go through 10-12 cords a winter in Alaska and had to buy a few cords a couple years. I made sure if I paid for a cord, I got one. I also cut on some forest service and they measured my loads coming out.

Not really sure what that little gizmo is?? Almost thought window washer squirter(looks like hose barbs on the ends), but don't think so.

And the mess stays in the trailer, don't have to rake and clean the yard in the spring.

Frieghttrain, sorry we hijacked your thread yapping about firewood. That gizmo is a puzzler. What are the hoses connected to?

Sorry about the bad link.. was my second time posting here I hauled a cord of wood a few weeks ago, dry and seasoned and the truck was squatting really bad, I've thought about adding overload or helper springs under the rear end to help some, but I have a friend who has a 3/4 ton rear end for a ford that he wants to get rid of for nothing... I just dont want it to turn out to be a headache swapping it out.

There are no hoses connected to it, just 2 wires, one going into the cab, (which I will chase down when it gets over freezing) and the other drops down between the motor and firewall.

An F-100 can definitely wood. My 72 was used to haul hay and firewood with almost no problems. The original 4500# GVW rear springs did get slightly flat so we upgraded to F-250 springs. One time we hauled 4 loads of hay at 32 bales each load. For payment, we weighed one load at a truck scales, and the bales averaged 125#. With those F-250 springs, it should made a nice curve cruiser with no sway. One time coming home from cutting firewood on a stretch of highway that had 27 curves with signs posted at 35-55, I held off a Vette who was right on my tail, but finally passed me on a long straight stretch.

looks like a vacuum-operated switch? if it is- there's no vacuum hoses hooked up to it, so its not doing anything.

I does look like some sort of windshield washer pump. Or maybe a vacuum switch.

And to answer any questions about the weight of a cord of wood, here is a pretty accurate table. Although my experience would be that it looses more weight when it's cured.

What kind of hay weighs 125#? I didn't even know there was hay to cut in North Pole (been there but wasn't looking for hay fields) The heaviest we have here is alfalfa and if they weigh more than 90-100# they are too wet and will probably mold.
