early/late steering gear swap
Will a later two tooth steering box swap into our '28 Coupe with the seven tooth box? Is it a bolt in swap? Will my new steering wheel fit the later column?
Thanks. |

Re: early/late steering gear swap
follow up on Brents "yes, yes. no". Your old 7 tooth steering shaft will have a splined shaft where the steerring wheel attaches- upper end. The 2 tooth shaft will have a keyed shaft on the upper end where the steering wheel attaches. Seven tooth booxes require a splined steering wheel = two tooth boxes require a keyed steering wheel.
The two are not compatible, BUT. I think Snyders does now offer a 1929 style steering wheel with a keyed center. Check it out - call Snyders. |

Re: early/late steering gear swap
We installed a F1 pickup in a 1930. I read about cutting welding a F1 Box?? we did
nothing like that just drilled one hole. We spliced the F1 shaft to the A shaft for the steering wheel. the spark and throttle on the column is just for looks because it has a 1935 V8 in it. Horn wire goes down the shaft good to go. for now a remote head-lite switch until we fab up something for the real switch. You want power steering; this is the ticket I tell you this made this a lady. Can't give details but my kid is a surgeon, not bragging but he is a master body and fab guy he can't play a note but my youngest is a master piano organ drums name it. He plays and smokes keys I can't see his fingers like lightning. So go figure: the old kid takes after me and my father the young one takes after my grandfather payed in Paul Whitemans band in the 30s forever. guess its called DNA. Sam I tend to ramble too much she says LOL |

Then they modified the column to work on the '30/31 cars. So look for a 2-tooth column made for the '29 vehicle and it is a "bolt in" upgrade.

Re: early/late steering gear swap
Your 1928 steering wheel is splined within the hole...Is it not?
Therefore, the steering shaft must be splined to fit the steering wheel. Pluck |

You have a couple of outs to get 2-Tooth steering. 1. Purchase a complete 1929 "Gemmer" 2-tooth steering including "open sectors" spark and throttle lever setup. You will need a 1929 Black (or Red) keyed wheel. This would be closest to what you have now. You may have to do a COMPLETE REBUILD of this steering box as it has the non-tapered cone bearings which were obsoleted and replaced with taper rollers about August 1930. You will need to examine your box for functionality as a non-taper bearing may be shot - or it may not be. Mine is not shot and I'm still going. 2. Decide to "mix & match" and settle on a 2-tooth steering column from a 1930-31 Model A but which is more likely have a "rebuildable" 2 tooth box - which may or may not need rebuilding. As this box/column will have "closed sectors" at the top and a different wheel than yours now, it will be a decided change - but possibly a cheaper change since the box rebuild if required is more likely to be routine. It really is not possible to FORCE FIT a 1929 keyed wheel onto a keyed 1930-31 column as the column lengths are different and you may have interference or stick-out. So you really can't swap parts between 1929 and 1930-31 in a steering column/wheel mix/match to seek the cheap way out. According to the Judging Standards the five following 2 tooth steering units were used 1. Gemmer/Pat.Pend in raised setters 2. Gemmer/Pat.Pend in sunken letters Both of these were used from Feb 1929 through May 1929 3. Gemmer/Patented in sunken letters This one used April 1929 through mid 1930 The units above are most likely to have the 1928-29 style "open sectors" column which you want. I would assume all of these are "non-rebuildable." 4. "A-3550-C" in sunken letters 5. "A-3550-C" in sunken letters and "F" in raised letter. Both of these used Jan 1930 through end of production SOME of these are NOT rebuildable - the change came in August 1930 - but all have the 1930-31 column and wheel. Hope this helps. Joe K

Re: early/late steering gear swap
I guess the smart thing to do would be to find good clear step by step instructions on adjusting the steering box I now have and then determine if I need to upgrade to a two tooth box. Mine might be good for many more miles with proper adjustment and lube. I have found several articles and videos on two tooth adjustments but it seems info on the early seven tooth boxes are hard to find. I just got the A and don't have any manuals, yet.

Re: early/late steering gear swap
Thank's Brent. I'm in Hudson, near Lenoir, Hickory, and Morganton. South of Boone just off of Hwy 321. Do you know Model A Mac? Good guy to deal with.

Re: early/late steering gear swap
There is not much adjustment that can be done on a 7 tooth. I just upgraded my 29 with a 2 tooth, it makes a huge difference. The bottom end is common on all 2 tooth columns, you need the upper 29 tube for your car. I had to get everything separate, all the vendors sell the 29 keyed wheel. The costs added up but it is so much better to steer now, definitely worth it.
