Ken's last two replies are comprehensible if you assume that the button needs to be at a specific (spring-loaded?) position for the gear to lock.
This surprised me, and I wasn't ready to assume that. I just checked my own Schlumpf (moderately old type: square taper but the high number of engagement positions). I have about 1 mm of play on each side, by which I mean that each button can be pushed in against a spring about 1 mm more than the normal pushed-in position. But if I continue pushing in and turn the cranks, the coresponding gear (high for gold, low for silver) stays locked.
So is this dead zone something specific to the newer splined hub? I wouldn't think so since I've always understood that the internals are the same between the two versions.

If it's friction between the shift buttons and the crank bolt, couldn't you try shifting without the buttons on the wheel by pushing with a thin tool to see if the fail disappears. If shifting then works fine, you and Florian are on the right track. Might save a few days.

After that I screwed the nut and button back on and worked out that I could reproduce the problem exactly when I push the button hard (all the way in), whilst turning the cranks. It needs to spring back about a mm or two for the gear to lock. Otherwise, the button seems to get stuck in this hypershifted position and doesn't come back out that mm to lock the gears with.
From what Florian is saying, there needs to be more play between the button and axle nut, otherwise it could potentially get stuck in this position. That's why he's sending me new nuts and buttons.
Hope that made sense.

I broke my crankarm the other day. Now I have to take off the cranks.
I used the tools it came with but it seemed to be stripped right away- on both sides.
So if I can hold one button I can loosen the other?
I do see metal filings when I check the 1.5 allen wrench
Thanks for the special tools, Schlumpf....NOT
It didn't help me or I'm too stupid.
