Transmission part needed

SuperDave

. This is a "back burner" project. I have a good single lever OD transmission from a 48-51 Hudson. The input shaft or as Hudson calls it "Main Drive Gear"is damaged.The part that inserts into the pilot bearing is damaged. I need a new one.. P/N is 302471. This is the 18 teeth version, Non Drivemaster. If someone has one, please let me know price. I would like to get this thing back together before I forget where everything goes!

Can the damaged pilot bearing portion be turned down? The pilot bearing is a bog standard metric 30 x 10 bearing. There may be a 30 x 9, or if not a sleeve could be pressed over the portion that's turned down.

Great idea Bob. I will certainly look into that. Seems like a simple proceedure to turn it down and sleeve it.. Thanks,

We had the same problem at Vintage Coach a while back. We took the shaft to a good machine shop, they built it back up with weld and then ground it back down to standard size. It was more work involved than money, don't recall how much they charged but it wasn't that bad. Remember you won't work for free and neither will anyone else, as long as it's a fair price.

I had the nose broken off on the front gear. The machine shop drilled into the shaft and threaded the hole, then machined up a new nose with an extended threaded portion which screwed into the shaft, problem solved.

There is allways a way (often more than one). In our shop where I used to work we had a "Metalizer". It sprayed molten metal on a undercut surface abd built it up. Then you just machined it down to the size needed. Same idea as welding but very little heat transfer issues,

"Dr. Doug" Wildrick and Al Saffrahn both rebuild a lot of transmissions. I'd check with one of them for a good shaft (but not a good shafting!)

When we used to repair print rollers with multi step journals, we would cut off the undersize/worn journal off, drill a hole into the core and then press fit a new section on. Then we would drill a hole perpendicular to the new shaft and into the new drilled out area and press a pin into both. Then turn down or finish off the new step. Another advantage was that you could heat treat then new section without heat treating the entire piece if you wanted to.
