    Looking at these old gearboxes it always occurs to me that, bar a few details, the insides of a 1916 gearbox (or other old box) is not that different to a more modern box. I rebuilt my XR400 not so long ago and its basically the same.

    As always I am following your progress with interest and look forward to your next installment.

    Thanks John. One of the things I learned in 2016 is it's that these little things can eat away all your beer drinking time on the Cannonball. Best to get them sorted out in advance. ;-)

    This little spiral bit is called the "worm" for obvious reasons. It actuates the clutch by pushing on that rod that we installed earlier.








    It has a little ball bearing that is held in by a wire clip. It's an easy job to replace the ball if it has a flat spot on it:










    Then just thread it into the hole in the obvious manner:










    And screw the cap on with a bit of your favorite sealer:










    In the next installment we'll assemble the felt seal on the output shaft, and we'll have a complete transmission.

    Thanks for that Kevin, the pictures are great (and will be quite helpful as get into my 1930 gearbox)!

    That's an excellent idea. There's nothing like being pretty sure you have an item you need, but if you do it's probably somewhere mixed in the mess in a large cardboard box.

    Were you this organized on the last Cannonball, or is this as a result of what you learned that time?

    Last time most everything was in large bins, mostly because we didn't have time to organize it any better. We lost a lot of beer time digging through those bins looking for parts and tools.

    Let's wrap this three speed countershaft refurb up. All that's left is the shaft seal. It consists of three parts, a thin flat washer, a felt seal, and a threaded retainer. I made the felt seal out of F-1 felt from McMaster Carr. If you want to see how I cut it out, scroll back about a year or so. Ultimately the felt will get sandwiched between the other two parts.









    You'll need an adjustable pin spanner with pins that fit the holes in the retainer.









    Drop the thin washer in on top of the bearing. Place the felt on top of it, around the spacer that we polished earlier.










    The retainer threads on next, with the recessed side toward the felt. Put some kind of sealer on the threads. The threads are left handed.










    Tighten with the pin spanner. Lefty tightie.










    And there they are. Two little Indian transmissions.

    Coincidentally, a few hours before you posted this I had decided to make a felt seal for the output shaft of my 1928 Ariel:

    I already had ordered the felt but was wondering how I would cut it once it arrived so that the ID would be a snug fit over the shaft. Not that anyone is counting, but your post about cutting felt was 18 months ago (time flies when you're having fun):
