Steering box light switch I’m hoping you all can help me once again. I am running a 1940 steering box on my ‘36 pickup but I still want to run the horn rod/light switch as it came in ‘36. Can I use my existing 1940 box or do I need to find an earlier box that came factory with the light switch on the box?
Thanks for the help |
Re: Steering box light switch Hi Everyone. OldGold, I'm not an expert but did, ten years ago, update a 36 car to having the later box. It involved using a later bulb/light switch housing that covers the light switch and spring bail that holds it on, if I recall correctly. I think you need longer than the 36 used.
Someone will be along that knows better than I. But it's doable. The earlier box didn't have ball bearings on the worm/sector so your later one is more better at ease of turning, like in parking lots. That's what I noticed the most. |
Re: Steering box light switch up to 1939 used the light switch at bottom of steering box.

In your case, you could use the '40 box by interchanging the '40 steering shaft with the original shaft from your '36 steering column. You would need to press the '36 worm gear off that shaft, and press the '40 worm on to the '36 shaft. This usually requires access to a hydraulic press, proper fixturing, and correct alignment of shaft and worm gear as you press these parts together. There have been some good posts in the past on how this is all done by a Fordbarn member known as.... "Neal in Ca" and I also did a similar post using some of Neals pictures. Those posts are in the archives. You would also need to find the parts from a '37 to '39 box that are necessary to mount the '36 light switch ball on the bottom of the '40 box. The major improvement in the '37 to '48 boxes was the addition of a rolling sector gear as opposed to a fixed sector gear on '36 and earlier Ford steering boxes. Once you switch steering shafts and use your '36 column tube, everything basically bolts back together and looks as it did originally. *Note: Another, and possibly easier option would be to find a complete steering column originally used in a '37 to '39 Ford PU. |
Re: Steering box light switch I’m not 100% sure that my box is a 1940, but it was removed from a 1940 chassis. It just has no provisions, that I can see, for the light switch. It was at some point rebuilt and painted according to the guy I bought it from. What changed after ‘39? The thru hole for the horn/light switch rod? Since I do not have a horn/light switch rod yet, does anybody know the diameter of the rod or at least the inner diameter of the pass thru hole in the steering shaft?

I’ve attached two pictures of my box. I’m sure someone here knows which year it is.

Re: Steering box light switch If it’s a 1940, is it a simple task to use an earlier style switch or should I look for a ‘37-‘39 steering box? I’m wanting to use a ‘37+ box only because I’ve read that they work much better.

Re: Steering box light switch can you not just change the end plate for an earlier one with the tube, or is the bolt pattern different 40 & up ?

Re: Steering box light switch You would need the 37-39 bottom plate with the brass tube. Your plate with the steel tube will not let the rod go thru. The rod is .380 or so. They are rolled and not completely round. There is an adapter with two catacorner screws to mount the switch. The rest of your parts will work.
Your main problem is the horn button. It will not fit a 40 wheel. I don’t know what could be rigged up to work. Maybe the od of you button could be cut down.. I don’t know if the length would work. A banjo would be easier. A 40 wheel needs 40 mast jacket column. A banjo would work with your column. |
Re: Steering box light switch Thanks for the info Andy. I plan to use a ‘36 wheel, and I believe that is what was on the truck, however it’s probably not worth saving since it has chunks missing.

Well I’ve found all the pieces to use the steering box mounted light switch on my 1940 steering box I’m putting in my ‘36 pickup. However, I think I am having issues with the Drake bail. I tweaked it some to get it to retain the switch but I am uncertain if it’s correct. Should the bail rest in the two dimples just past the grooves it’s currently in or does this look correct? Please see picture. Thanks!

Re: Steering box light switch Wrong bail. It needs to snap into the dimples. Stand the bail on its end and measure to the top of other end where it attaches to the plate on the steering column. What is that measurement? There several different lengths. Been there done that.

Re: Steering box light switch Hi Lawson. I read thru your posts when you were messing around with your bail. This is the Drake bail, part # 78-3647. It claims it’s for 37-39 pass and 38-39 p/u. Any idea what the correct bail number is?

Re: Steering box light switch 1935-36 is 48-3647

Try a "78-3647" for the '37-'39 bail. The '37-'39 box adapter for the switch is going to look like the one on the LEFT in the picture below. 2nd picture is a '39 set-up. Hope this helps! "A" in the third picture is the '37-'39 BAIL.

Re: Steering box light switch I am using the 78-3647 bail. It retains the light switch just fine, it just does not settle into the dimples as shown in my post #13. I also have the correct light switch bracket for ‘37-‘39. Maybe I need to find an original bail to try.
|
Re: Steering box light switch I’m not finding any other light switch bails that are any different than the 78-3647 bail from Drake I am already using. I guess it’s possible the Drake version is off just enough so I either modify it or look for an original. I’m open to suggestions. Thanks
