So sorry for writing in English, I'm writing from the US and unfortunately don't speak German. I picked up this beauty on Ebay, and she is gorgeous! Someone really took care or just had this stored really well for 40 years. I can't find a scratch or a ding anywhere. Even the foam inside the springs is perfect.
Unfortunately, there's some problems with the mechanics. The motor runs and is quiet. I'm following a tutorial to re-grease the bearings and will clean and lube / oil the linkage while I'm in there. I still think aside from that there's something else wrong. When I rotate the spindle, I could feel an obvious grating at one point in the rotation, and I can't imagine the bearings having such an impact.
I suspect (but don't have a reference) that there might be a problem with the linkage:
Armature wire (A) isn't connected and just sits on top of spindle locking lever (B). During my initial tests as I rotated the spindle clockwise by hand, I noticed the B would contact a detent in the spindle and would seem to lock it. I didn't apply much force. Should A be connected to B in some way other than to sit on top of it?
Also, looking at the underside, there is a large metal gear that with moderate force applied will not turn. I'm assuming it should, but I'm not familiar enough with the mechanics to know if they need to be in some "state" before that can happen. If you understand how this should work or rotate please advise.
Here's the pic of the large metal gear that won't turn with moderate force applied. Do I need to remove the brackets and linkage and apply lube to free it, or is there some mech. configuration that needs to be engaged for it to turn?
I'll post more pics as I progress.
Lastly, I really appreciate any help, feedback or opinions you can lend.
