I have what I think is a mid 40's ford truck steering box. It's push-pull steering, but not an F1. The internals are identical to the F1 design, but slightly larger. I'm trying to locate a pitman arm for it, but I don't even know exactly what to look for. Does anyone have any ideas? I'll try to get some photos tomorrow if that helps.
Sounds like an F100 box. Get a measurement of the spline that the pitman arm fits onto. I run a 49-54 Chev pitman arm on an F1 box. My memory tells me that a Falcon/Mustang one fits the F100 box.
Not F100, it's splined just like 37-48 car ones, but slightly larger. I have an early f100, and 40 Ford passenger car box to compare. F100 is a pinch bolt.
Well cut off my legs and call me shorty I believe you're right. Best we go back to normal programming.
Maybe COE? Larger truck maybe? I'm clutching at straws here. The box looks great and will work for my build. But it's useless without a pitman arm.
How does the pitman attach to the box? If i remnember correctly, the F1 uses a cross bolt through the grooved gear box shaft...and the F100 is held on with a large hex nut on the splined shaft...or maybe I said that backwards.
Do you have a dial or digital caliper? If so, measure the diameter over the splines at the fattest point and let us know.
Yep! I told you wrong...I went out and checked...I have a `55 F-100 column and gear box assembly ; It uses a cross bolt to hold it [pitman arm] to the gear sector...The F-1 and older will have the hex nut.
I have a pitman arm from from a 49 f6 box that I have no use for. Its yours if you want it just pay postage. I should check, is you box a gemmer box?
The box appears to be 48-52 F-4, 5, 6. The sector shaft is 1-1/4" right? Boltboy's F-6 pitman arm should work, or any other 32-52 BIG truck pitman arm. Neal
The pitman is about 8" center to center. I dont know what kind of ratio that would give you. For comparison my 1.5 ton Dodge has a 10.5" pitman arm and it steers well... like a big truck.
