Foot and hand brake linkage:

After correcting the upside down crossmember, the brake linkage has been installed for a fit check. It’s a clever system. The foot brake rod runs down the left side of the frame, and via a torque tube, actuates the outer brake bands. Similarly, the hand brake rod runs down the right side of the vehicle actuating the inner brake bands.

I needed to fabricate two of the shorter rods as the originals were rusted and bent beyond limits. I was able to straighten and save the others. I spent quite a few hours cleaning each clevis and chasing all the threads. A little time spent here will pay dividends during final assembly and rigging. I was able to save all the original jam nuts and clevis forks. Once I’m satisfied with the fit and function, I’ll disassemble for paint.

Re: 1917 model F

Hi Tim, Great to,see your progress, we are just starting restoring our 1919 Model G and have the clutch apart and the overhead valve motor pulled down so we are quite a few steps behind you. It was interesting to see what your dad used to cut wood. Our truck was used as a well boring rig and later used to power a circular saw but not sure where the saw was mounted. Regards John M

Re: 1917 model F

Magneto setup:

The Bosch DU4 doesn’t seem to have enough spark at low rpm. 60 plus years in the barn didn’t help and who knows when it last ran as a stationary engine. After disassembly and cleaning it actually looks pretty good inside and out and makes a good hot spark above 150 rpm or so. However, it’s not good enough for hand cranking with no impulse. I’m looking for a magneto shop to get it rebuilt properly. My previous magneto guy passed away.

In the meantime, I have a fresh rebuilt Eisemann mag with impulse on the shelf, so I’ll pop that on for a first start attempt. Rotation is correct and it has a 35 degree impulse which should help greatly with starting safely. I’m milling a coupling from 6061 aluminum stock and should have a nice clean setup. I’ll post a photo once done.

I much prefer the period look of the American Bosch DU4, but I’ll take what works for now. Looking forward to a first start attempt soon.

Re: 1917 model F

New magneto and first start:

I machined a coupling for the Eisemann and it fits up beautifully. I timed it to fire right at top-dead-center and the impulse should fire at 35 degrees past TDC.

With a few shots of gasoline in the primer cups it started on the second crank. That’s the first time it’s ran in 70 plus years and I’m quite pleased. Seems to fire on all four equally and all is normal so far. The fuel tank and line to carburetor is not installed yet, so it runs on the primer cups only at this point. I’m just happy to have a good hot magneto and correct timing.

To do list:
~ fuel tank, clean and install
~ fabricate fuel line to carb
~ route ignition wires properly
~ fabricate hold-down strap for Eisemann magneto
~ source exhaust gaskets (Olsen’s?)

And much more...

Pinstripes on gunstock:

The instruction manual refers to the floor support structure as the “gunstock, left and right.” Original pinstripes are still visible on my Model F. I didn’t notice them though all the rust until the lighting was just at the correct angle. I highlighted the pinstripes with a black sharpie pen and carefully took measurements. For those that might be interested, I documented the location while they were still visible.

I wasn’t planning on doing pinstripes, but these will be reapplied to the gunstocks as originally delivered. Yellow/gold striping on gloss black background.

Thanks. Hoping to see your project come together as well. I’ll continue posting my progress with emphasis on the headaches and surprises along the way.

Thanks. The original colors were a bit of a mystery for awhile. Plenty of barn dust and rust. However, my dad remembers the truck being red and black with some yellow highlights. So I’m going with that.

Re: 1917 model F

For those that might be interested, I posted a YouTube of my model F running nicely on the Stromberg M2 carburetor and Eisemann magneto. One may search for “1917 International Harvester Model F”, or follow the link below.

I saw earlier posts regarding interest in throttle linkages and such, so I attempted to show some of these details.

Re: 1917 model F

Very good and informative video.
The petcock and tin can primer setup is sweet... I gleaned an idea from that :)
Fun stuff...

Thanks for posting.

Be safe
