4 Darn….This Just Might Work

With it finally determined that we had successfully mixed-up a bunch of factory B-W parts into a combination that the factory probably never dreamed a need for, and feeling comfortable that it would function properly like any other B-W T5 would, we had one more big hurdle to overcome. Like I mentioned earlier, the Jeep output shaft has an oddball 23-splines at the rear end of the shaft. We had to find a way to adapt the 23-splines in such a way that we could fit a stock Ford 6-spline U-joint, as used at the front end of Ford torque tubes. We also felt that the U-joint needed to bolt to the rear of the Jeep main shaft just like it bolts to an old Ford 3-speed main shaft via a drilled, threaded hole in the end of the shaft. As luck would have it, I happened to run across a guy on the HAMB that goes by KATO KINGS. Turns-out he also lurks here on the ‘Barn under the name CRANIUM. Cranium makes the round, aluminum adapter plate which bolts onto the rear of the Jeep 4X4 housing. That plate is pretty straight forward and easy to build for most folks that can carefully lay-out a pattern and operate a drill press. More-importantly though, Cranium makes a beautiful 23-spline adapter (as seen below) from scratch, which also accepts the front of the 6-spline Ford U-joint. The adapter slides onto the 23-spline Jeep shaft, and the U-joint slides onto the adapter. An appropriately-sized bolt goes through the U-joint, the center of the spline adapter and threads into the end of the Jeep shaft. The shaft was rather easy to drill and tap to accept the bolt just like a Ford 3-speed main shaft. The END of the Jeep shaft does not appear to be case-hardened like the rest of the shaft surfaces. Like I said, this spline adapter is a beautifully-machined piece, and Cranium is rather proud of it. Nonetheless, it is a nice yet necessary part. The aluminum adapter plate is drilled and threaded to accept a ‘32-’36 Ford rear bearing retainer (pictured). This RETAINER is the piece that houses the U-joint, and that the clamshell assembly for the torque tube bolts to. This is everything that’s required to bolt-up a Ford torque tube.
