Koln column rebuild-turn signal arm not resetting

[ataraxia]

Anyone have a write up on how to get the turn signal cancellation on the Koln column to function properly?

I took my turn signal arm off to find the broken spring - replaced the spring and put it back - ensuring that the little triangle bit in the middle would actuate when either a left or right hand signal are initiated. The arm doesn't return to neutral, however, and I've run out of things to look at/for to get it to work correctly.

I can upload a video later today...

If it functions correctly when you test it without the wheel, either the steering column housing needs to be moved closer to the wheel or you have the wrong "tang" on the back of the steering wheel. I've found that Type 1 tangs sometimes don't mix with Type 3 columns.

I measured the thickness of the SWF and the Koln turn signal arms - they're essentially the same thickness.

Koln turn signal arm:

SWF turn signal arm:

Here's a photo that shows the gap in the arm/column (yes, I know the speedo isn't year correct):

No visible part number on the cancellation ring - but it's a standard part so it shouldn't be the culprit. It's the same one that was working just fine on the SWF column before the ignition switch croaked. AFAIK, this is the original steering wheel/cancellation ring.

Now on to the detail bit...this first image is the 'neutral' position and the red arrow points to nothing to be 'caught' by the canceling ring:

Here's a 'left' turn:

Here's a 'right' turn:

In both of the 'turn' situations, you can see the triangular bit sticking out - from what I can tell, this should be caught by the cancellation ring and trigger it to go back to neutral...but that doesn't happen. On an SWF column, I've used a flat blade screwdriver to 'click it' back to neutral but that didn't work on this one.

I'm out of ideas...

so swap the levers if you can.

I'd swap columns -it's less hassle but that doesn't solve the riddle.

Having similar problem...Did you solve this?
