Technical Banjo conversion to 9 inch

I'm positive this has been covered extensively. I'm still a noob, and I did try searching the site.

I have an original Banjo resr end. I'm considering doing a 9 Inch conversion during the cold months. I found this kit, anyone have experiences good or bad?

It's just a hotrod thought --(sometimes they race in, and sometimes they get towed out), I'm not committed to it. Just wondering.

Thanks, Robert

 

I converted my banjo to Ford 9" axles on my Mysterion project. Those axle ends you show work for sure but I am a more DIY guy so try not to buy the aftermarket stuff. Here is an article that published in Street Rodder mag in '85. I sort of followed it but did a few things differently from them.




I bought the bearing adaptor plates instead of making them.


Since I had to narrow my (four) banjo axle tubes, I cut the ends off the axles making it much easier to cut off the factory bearing extensions and machine the oil seal hole. Then welded the ends back on the tubes.

I narrowed my axle tubes a lot for the Mysterion so I machined the axled ends so they slipped inside the tubes. This made the welds to reattach the ends right at the flange and thus invisible.



I ran Lincoln backing plates and brakes.

Here is what is needed inside the gear set. The bores in the ring gear and spider gear carrier need to be bored out to fit the bosses on the 9" side gears. These parts are VERY hard! Use carbide bits and slow feed on the lathe.


Then the side gears need modified too. They mesh perfectly with the banjo spider gears but are too big in diameter and the crowns of the teeth are a 1/16" or so too tall. You can machine them smaller in the lathe but I just used my grinder.

 

Good info. Thank you.

Wish the old man was still around to pick his brain. Course it would turn into something waaay out there, with quick change gears and s***

 

Willys36... thanks for taking the time to post that! Even if I never get around to doing something like this, I still thoroughly enjoy looking at it and reading about it!

I always look for ways to convert a junkyard treasure into a rod part. Just rubs me the wrong way to buy a shiny billet hunk when I can give new life to a cast iron jewel! So I do silly things like using factory MII crossmembers instead of store-bought ones, convert old points distributors to electronic with Chrysler parts, made my own Dual Range Hydramatic 1st gear hold valve (it works!!), reverse my own Corvair steering gears, made my own disk brake system for my '36 Willys beam axle using Ford Torino parts, and the dumbest thing so far, build a Mysterion reproduction which is a 100% DIY project!!
