Technical Is F2 "steering"gearbox the same as F1????

I've read everywhere about using a F1 gearbox on model a builds. My question is there a difference in the F2 and can it be used?

 

Are getting confused with steering box? Or, do you really mean gearbox?

 

~Steering gear box~

 

According to other threads here, the F1-F3 boxes are the same and they get bigger after that.

 

I have both. Was told by a old friend,in his 80's, who has owned ,collected, and worked on F-1's and F-2's, that the truck's have slower turning ratio, you will turn the steering wheel more to make the turn.

 

UPDATE: The steering box pictured to the right turns out to be F4 or larger. Please disregard.
I think the F-2 box is bigger. Here's a side-by-side pic that was posted in the parts for sale section a few weeks ago; according to the seller, the F-1 box is on the left (painted) the box on the right is F-2 (rusty).

I saved the image because--presuming the seller's data is correct--the supposed F-1 box I bought at the Monroe swap meet a few months ago turns out to be F-2. But at $25 for box, column and wheel, I really can't complain.

Here's a link to the ad--there's more pix: http://www.jalopyjournal.com/forum/threads/1948-1952-ford-truck-steering-box.987095/

 

This may answer your question....

 

"C D and Y" use the same box.....so f1 f2 and f3

 

I see the physical difference. The only reason i'm asking is because I may buy a f2 for its motor. And it has all steering.

 

That box is not a F2! It's a F4 or larger. F1- F3 are the same. I,m the one bought that box. I wanted the larger for my modified. It takes a larger Pittman arm.

I made this mistake before and im still looking for a large pitman arm to go with a beauty box column and wheel.

 

Thanks HD Driver, that is good to know. After seeing the parts info posted by fordfitrucknut, I was wondering if there wasn't something wrong with the description in that ad. Sorry, all, for bringing misinformation to the thread.

 

I've seen a few f-3s in junkyards around here they were all big steering boxes... I have always believed f-1, f-2 were small boxes

 

So your saying f1 and f2 are the same?

 

I'm going to say yes based on what I have seen

 

Seems to me I had the same problem years ago and found a latermodel pitman from a gm steering box like a vega or bigger Saginaw unit that fit

 

That would be great!. Thanks for that. I have a vega arm and i will report back.

 

If you have chance to buy a F4 or 5 box, that's in good condition, don't pass it up. Even though there larger, they still are very useable, especially in a four cyl. application! But I would pass on one without the pitman arm. There very hard to find. The pitman can be modified by cutting of the ball and drilled and tapered ( 7 degrees) for a early style Ford rod end. More than enough material there. You can also fit a standard ford F1 steering wheel . Hope this helps out.

 

Is the earlier jail bar steering the same setup as F1 to F4? Still trying to find info. Also the crossmember

 

I thought they had cross steer passenger box

 

It might have been like a 525 or 605 Which is bigger ..i was pretty sure it was gm at the time

 

Makes sense. If i remember the od of the spline was 1.125. Vega is smaller than that.

 

Correct.

 

I'm confused! Wasn't the question ; is a F2 box the same as an F1? The answer is, yes!
