I ahve built and rebuilt a bunch of them. Since yours has a standard Model A bellhousing I know it is not one of mine. I still do maintenance work and rebuild some of the parts on the inside. I am completely out of useable gears, but still have syncro rings ans bearings - new and good used.


Gary Bernard is still in the business. You can probably find him thru the Ft Worth Model A club.



If you need call me 903 952 7615.

I've currently got 2 of these transmission on the bench, being built for Model A's. Refer to pics --- there is only 1 washer even close to the size of the one pictured. It's an "E" clip for the Reverse Rocker. The reverse rocker is located in the top of the trans and provides the spring pressure, you must overcome, to put it in reverse. All the other washers are either, large, strong spring clips for the bearings or are captive on their shafts, so unlikely it's any of them. Or possibly at some point the cover was off and a bolt washer was accidentally dropped in there. There is a large, weak, magnet at the bottom of the trans. Looking from the bottom it's in the bulge near the front of the trans and held in by a one-way spring clip.

For those that said the gears look like they have dents or chips, they look perfectly normal to me. Look at the gears in my trans. They ALL have machine makes that look like chips but they are machined on every tooth, all the way around. They all have them. I don't know why but they do.

Without giving away any details this trans is the "Goldilocks Ratio" that was said could not be built. I'm working on writing-up the details of how I accomplished this but I've built 2 of these with the 3.09 first and 27.0% O.D.

Just talked to Gary Bernard yesterday, and yes he is still doing these transmissions. I just about have mine in. Gary does a great job on these. Only three modifications so far, brake cross shaft, and shortened torque tube and shortened radius rods. Gary did the torque tube and brake cross shaft. First Class guy! He has been very helpful!

Probably within a month or two. I literally just started documenting the process. Got a lot of other things going on that hinder my attention to projects like this.

I'd forgotten about the tower shifting mechanism. From the parts break down there appears to be two of those clips on the reverse rocker. The retainer rings are as follows: are P/N 97513, a 5/16" retaining ring for the OD/3rd rocker and the two P/N 97411, 3/8" retaining rings for the reverse rocker in the tower housing. The two 97411 ones are the E-clip style and look different but the 97513 is an external snap ring. Ford/New Holland uses these part numbers on some tractors.


If a part is substituted, be sure it fits the pin well. A person wouldn't want anything to fall off again if that's what happened. If they are all still there then it's a mystery about where it came from.
