Late Shifter Housing on Early Gearboxes Let's say that you have a late style shifter housing 68-7222 or 81A-7222 and wish to mount this to a gearbox that is built with the early 1932-35 gears. So I changed it to run the operating rod in the same general orientation as was stock, Henry Ford did a lot of good things, and I think this general setup was good too. Upgrading the early three speeds with the late style 1940-48 gears and synchronizers is a common option. Remember the driven gear is locked to the brake drum and therefore turns the brake drum and driven plate remember its bolted to the drum and therefore the driveshaft at the same reduced rate. However, in my case, I stopped to weld up a new battery box. If you have the early type, with the handbrake lever in front of the gear stick, you will need to purchase the appropriate handbrake lever and mounting bolt set. Once the transmission is bolted back into the car, I turned my attention to the differential.
If you have any of the following cases, you must make this change to allow the main drive gear to fit: B Case 1932-34 four cylinder 18 Case 1932-34 V8 motor 48 Case 1935-36 V8 motor Since the 1939 to 48 main drive gears 81A-7017, 8M-7017, 26H-7017, 56H-7017 have the 30 tooth synchro ring at the back of the gear, this may interfere with the large end of the cluster gear during installation, preventing you from pushing the main drive gear all the way into the gearbox. We had taken this image from the web we think would be probably the most representative pics for 1932 ford model b transmission parts. The 1942 to 1952 rear mount 21C-7085 was used on the light trucks with the open driveshaft, so if your vehicle will have a regular open driveshaft, you will have to use this rear mount in conjunction with the open drive mainshaft inside the gearbox. . On stock 1932-35 Ford cars, this means that the shifter tower opening in your floor pan will have to be opened up to the front an inch or so to clear the upright type late style towers. And while the kit takes some tweaking to install, it is still a good value for what you receive. It is bolted to the brake drum and therefore connected to the driven gear.
This converts it from a torque-tube to an open driveshaft. The early lever from 1932 through 1935 model years had a short stub end the part that goes into the shifter housing , which was designed to operate with the early shifter housings with the slanted tower.

The 91A-7511 was used in 1939 only. This was a lot of work. You take the gear from the original torque tube, and machine it so that it slips over the new shaft, then pin it in place with a tension pin. This gearbox was also available on the Ford light pickup trucks through 1952 production. By using this service, you accept the terms of our. This section of the main drive gear will now clear the large end of the cluster gear. Note: This is the style that had the handbrake lever to the right of the gear stick.
Lewis, who must be the owner. Here it is at work: Once the torque tube is out, the transmission can be removed. Can you find someone with those gears and ride in their car? Model T Ford Transmission Components The Model T transmission is perhaps the least understood parts of the Model T Ford. Thanks for looking and good luck! So I machined some short extensions to where the rear anti-rattle springs mount, and then machined a stop that slides over each rod with a set-screw to capture the spring and put tension on the rod. When the transmission is out, the new clutch disk can be installed, using the existing pressure plate.
You can see it in this picture. The only benefits are no more double clutching and better ratios in first and second. Mitchell has addressed this in their syncro gear sets for the Model A. The higher ratio gears did not come out until 1940 but could have been installed in a 36-39 gearbox. The Model A is a little low in first and then a big jump to second for some peoples liking. Note: I've received several emails after writing this.
Going on a rally might be fun but the driving will get old soon. The T5 is metric in its entirety. You might need 2 of these 400g grease gun cartridges, if you are starting with a clean universal joint. Use Classics on Autotrader's intuitive search tools to find the best classic car, muscle car, project car, classic truck, or hot rod. The driveshaft included with the kit fits well, although I think it could be about an inch longer so that it would engage more of the splines in the transmission output shaft.
Transmission Gear Sets The changes in the Ford transmission gears were, in general, an ongoing process over the years. The new brake rods all fit fine, except the one from the pedal to the cross shaft, which needed to be shortened after my geometry change. Also, the hole in the T5 needs to be bored to a larger size to work with the kit. Not all items pictured are available. We know everybodys opinion; will be different from one another. The kit is invaluable to doing the job - things like the motor plate and machined parts for converting from torque tube to open rear end would be extremely hard to fabricate on your own.

Many of the parts were primed in red oxide. The 1932 through 1948 passenger car mounts were designed to be used with the closed drive torque tube driveshaft that Ford used. You can substitute the 67-7100 gear in place of the B-7100 gear. You will need to install your gear shift lever, which is not an easy task without using the correct tool. If you use the Model B oil pan on the Model A you will have a leak should I say gusher at the rear main unless you modify it.
