Gotta agree with Jim get it up to scratch mechanically put an old bed on the back and use it as is.

Remember these trucks are only good for about 20-25mph tops.

If I could find a good non rusted out old girl I would keep it that way they have so much more appeal at the shows don't worry about it having the wrong engine remember it is 90 years old and as we know most 90 year olds have had something fixed or replaced during their life time.

Thank you for the advise and the information on the engine. I will post updates of my progress.

Sam

Your truck is a "Model S".
Subtract 501 from the serial number and you will have the actual production number of the truck as IH started serial numbers at 501.
Being over 32000 it is close to the end of production, late 1926 or possibly even early 1927.
Not at home so don't have resources with me to tell any more precisely

Your memory is not to bad. Had a look and there where 33,466 produced so Sam your truck is nearly at the end of the production.

Bill and Trevor
When you say "the end of the production run" what do you mean? End of production for the model S in 1926 or do you mean end of production for the model S ever? Were there 33466 - 501 model S's made in 1926 and in 1927 they started at 501 again?

There where only 33,466 model "S" trucks produced in total. International always started the chassis numbers at 501 for each model produced.

So there would be chassis numbers 501 to 33,967.

Yours is 32,747 so that is why we said it was close to the end of production.

Sam,
Looks like your truck was 220 from the last one built.
Yes, the Model S and it's variants the Model SL (underslung) and SD (dump truck) all ceased production around the end of 1926 or very early 1927.
These 3 models all used the Lycoming KB engine which was an old design dating back to 1914-15. The KB engine has 2 main bearings and is splash oiled. Lycoming in 1923 introduced the CT 4 cylinder engine with 5 main bearings and a full pressure oiling system. It may have come to the point that IH was the only customer still using the old KB engine and that Lycoming wanted to better utilize production space.
It is my belief (theory, no hard documentation) that Lycoming was the driving force in their production ending, as it left IH without a 1 ton truck until the the Six Speed Special went into production in late December of 1927 (25 trucks built, 501-525). First SSS built in 1928 was 526.
Bill

Sam,
You asked about the gauges. Does the oil pressure gauge have a max of 4 psi? if yes this is likely the original gauge to the truck. The KB Lycoming engine uses a plunger type oil pump, much like a pump oil can, and pumps oil up to a gallery where the oil gravity flows to the main and cam bearings and connecting rod dipper troughs. So the only thing that really creates any oil pressure is the resistance of the oil flow through the piping, about 2 psi. All the gauge really tells you is that the pump is pumping.
The ammeter looks original as does the Stewart speedometer. I am unsure on the ignition switch. Is it a Remy? Or a Northeast? a closer picture may help if not too inconvenient.
Bill

Bill and Trevor,
Thank you very much for all your help.
See ignition picture below. I can't tell if its Remy or Northeast.

On the back of the ignition it says Milwaukee.

I guess the Stewart speedometer was very popular at this time because on the Dodge Brothers Roadsters videos on YouTube they used it as well.

Sam

I agree with Jim. Fix it up so you can have some fun with it. At least if it is as solid as it looks. When they fall apart you can restore them. Now it looks like that is what happened to the box so now you can "restore" the box. That's what I did with my 6 speed special, but eventually they do get too bad and you have to do something.
