Sounds like the mechanism is out of sync. Are you sure you put all the gears back in the correct places? As I understand it you have to ensure the gears are meshing in exactly the right places.

Welcome!

Check the height of the brass nut over the big wheel. I had the same problem exactly a few years ago and it took me some time to figure out what was wrong. It seems that this is not an issue on all versions of this Aiwa mech. 

Also, it could be that the belt, not being tight enough, doesn't have enough torque to finish the sequence.

I even found that it wasn't necessary at all to mark the gears for correct placement after all.

Correct, but it does make things much easier for non-tech people at the kitchen table guided only by forum posts and emails. 😂

Thank you for your replies.

I tinkered a bit with that brass knob. But without any result. Nevertheless I found it a little bit hard going when I pushed the gear with my finger.

And then :  I saw that little gap where you can see the belt. And it was slowly creeping forwards when the gear stopped. Perhaps that is it.

Shall I use another belt? I bought this one at an ebay-seller last winter already (I do these things only during wintertime ) and thouht  that it is very thin.  

The belts for B&O you will find on the Internet are usually pretty useless.

Ask Martin, aka Dillen! 

Get a belt from Martin, and adjust the brass nut so the gear has about 0.1 mm radial play. Finger tighten the nut until it sits block with the gear, then loosen the nut about 1/3 turn, check that the gear is moving freely. In the weekend I will open a CD50 I got from Rich.

OK , I think you are right, chartz. I try to order a better one from Martin. Contact over this forum or how does it work?

Regards

Bernd
