Houdini & Sachs Selector Key

Both keys can be done but the larger ones are a lot easier as you have some more room in the mainshaft.  10-4 on the chamfer towards the selector shoulder.  I had one instance where I even lost the retention cup and spring from its keeper and was able to fish it back in place and finish the job!

Kip,

Uncle Ted made a rod that was shoved into the countershaft side of the shaft to keep the detents into place until you shoved the selector rod back into the shaft.

Chamfer Revisited:

I reexamined my key collection.  They all have a small chamfer (~0.030) on both sides except one.  The key without the chamfer on both sides appears to be a well used OEM.  I mistook the chamfer for the thread lead-in.  My old eyes and lack of attention to detail ...  If you are lucky enough to have OEM/NOS, chamfer goes next to the boss on selector rod.   It is always a good idea to trial fit new parts. Guys, thanks for getting me back on the right track.

Ernie,
  Thanks for you valuable step by step process on this process to change shift keys.  It is wonderful to have some like you add so much to this site.  So many times trying to describe on this site or over the phone a process like this is difficult at best.  Thank you.

Dane  I modified a phillips screwdriver to shove through the mainshaft and push the selector rod out.  Works great but you have to keep constant pressure on both to make a smooth transition.  Kinda like riding a bike, don't think about it too much as you will mess up!;)

Ron,  My post are self-serving.  I'm just trying to learn all I can about these wonderful, weird and wacky Sachs motors.  The POG is a great source to "sound-out" ideas.  As usual, there is someone out there who has done it before.  I do try to post in a manner that will make it easy to Search for those just joining the group.  What started as a sometimes unpleasant necessity, has turned into an obsession.  I actually enjoy solving the problems as much, sometimes more, than riding.  And the big payoff is having the bike run cleanly the whole weekend, shift crisply, ... snag an occasional hole shot ... take the checkers.  Penton has always stood for excellence.  The POG models this very well.  My many thanks to those who have brought it this far.  

Kip,  I know what you mean about constant pressure/smooth transition.  I just used a large Philips and had some trouble getting the rod past the detents on the way back together.  A ground rod matching the end profile of the selector rod might be the ticket.  I wonder what Uncle Ted's tool looked like?  I have at least one more key to swap.  Wish us luck...

I just completed another key swap and presto-chango it was a snap.  I ground down a large Phillips per Kip's suggestion and it worked just fine in retaining the detents in place and allowing a smooth re-install of the selector rod.  Hopefully, this will be my last one.  Now, I if I can just get it to shift like a  ... Sachs;)!  I know, I know ... use the clutch ... every shift:(
