Re: 2 Tooth or 7
My preference is the 2 tooth because it is easy to rebuild, parts are available and the adjustments are improved over the 7 tooth. The Service Bullitens have excellent adjustment procedures for the 2 tooth.

Re: 2 Tooth or 7
The two tooth sector gear was used in 1929 (after May, I seem to recall) . It had a splined shaft and used the 29 type steering wheel and spark and throttle rods, I dont know if you can locate one of these steering gear complete but its worth a try.
The two tooth is a much better steering gear. You can help a seven tooth by installing a short pitman arm which are being made new by Snyders. As a matter of fact I installed on on my Feb. 29 Roadster and it sure eased up the steering. Ron |

I rebuilt my 7 tooth and so far it has worked well. But like was pointed out, the 2 tooth has some advantages. So good luck with whatever you do.

Anyone have a suggestion for tightening up a 7 tooth other than a complete rebuild? |

Re: 2 Tooth or 7
Yes, end-play is adjustable for both the worm and sector gear in a 7 tooth. Mesh is not. I was just hoping someone had come up with a reasonably easy fix similar to the 2 tooth's mesh adjustment. Installing a late model steering column won't really work for me.

Re: 2 Tooth or 7
I have both the 2 and a 7 tooth...Going with the 2 tooth. My frame is almost done except for one rear brake drum which I should have done by this weekend. Body is at the strippers. 3 years latter I'm gaining on it!
Thanks Fred |

Re: 2 Tooth or 7
I remember something on the Barn about having to make changes if your rig had a 7 tooth and you want to install a 2 tooth. I am sure someone on the Barn knows much more about this than I do and may respond.

Re: 2 Tooth or 7
The 7 tooth gear lash can be adjusted. This accomplished by making an offset bush .The bush is machined to a slip fit and after adjustment is locked by an industrial epoxy glue. The worm is a "two start" so can be rotated 180 degrees effectively so in the dead ahead position the sector is engaged in a "new" bit of the worm. My local "A" machine shop has done dozens over the years and never ever had one become "unglued". There was a demand here for this service as RHD 7 tooth repro parts were not available.
