1929 7 tooth sector

can the 7 tooth sector shaft be removed from the steering box without removing anything from the frame or motor?
 
I've wonder the same, but not tried it....yet.

That said, my opinion the seven tooth steering box is grossly under rated. If you take the time to purchase several NOS sectors you will find some are over size to compensate for wear on the worm. Mix & match until you have as little play at the steering wheel.

I found Granger has bushing stock. Hone to match.

I believe the shaft hits the front axle as it comes out the end. Loosen the gearbox mounting bolts to remedy that.



Find anyone who currently rebuilds them?

We do at my shop. Larry Shepherd does. The deal with rebuilding a 7 tooth is just like Jim suggests, in that there is much more time needed because you need a lathe and a hone to do a good job. Timesaver is your friend also when it comes to fitting the sector & worm gears. Just because something is more difficult to restore should never be a valid excuse for switching to a later steering gearbox IMO.

I think you misunderstood my question. I did not mean the steering wheel shaft but only the 7 tooth sector shaft. the only 2 things it might hit is first the starter and if it gets by the starter then it could hit the motor block. I hope this helps.
 
I do not know if you can walk that shaft out without taking the column loose. I had mine apart years ago, and I can tell you that you are gonna want to replace those bushings. Make sure your vendor sends you the steering box bushings, not the water pump bushings. They are different, and they are directional. Then when you slip your shaft back in skim coat it with axle grease before sliding it in, then wipe out any excess (although it should be minimal).

This does assume that you are going to end up pulling the column...

Yes I did. I apologize. The angle of the teeth plays into your favor in doing that.
 
yes, it can be done. I just finished up putting in the 2 sector bearings in from the engine compartment. once you take the steering wheel collum down you can pull and twist the collum anywhere you want it. I made a puller to remove the 2 bearings at the same time, not much trouble at all. I then installed the top bearing in place and then installed the lower bearing in place using the same tooling. i am going to try to load a picture of the tooling i made up. i have never been able to take a picture in all my 78 years. so, if you need more information on how i did this, please let me know.

I know I have posted this before but might help someone . The worm is "two start" in the 7 tooth . Remove the sector enough to disengage it . Rotate the steering wheel 180 degrees and push the sector back in . The sector is now engaged in what was the back side of the worm there will be less wear there . This does work I have tried it , Offset bushes can help too . This was done before RHD 7 tooth parts were available .
