Dual 1219 ball bearing help (not dearing ring!)

Hello All,

I am servicing a dual 1219 I found recently, in really pristine condition. disassembled and lubed the speed control, cam, relubed the motor bearings, replaced the stauerpimpel and dearing ring rubber parts. I was fixing up a problem I made myself when I reassembled the cam shaft where the tonearm cueing level was not properly seated in the groove, when a heard a little noise, and a ball bearing fell out onto the table. This ball bearing is larger in size than the ball bearings used for the dearing ring, and I do not know the locations of any other ball bearings in the chassis. Does anyone know what this might be? I am very excited to get this thing finished and spinning vinyl!

Thanks!

Shot in the dark here, but it sounds like the bearing for the shut off slide.
There is an arm that is connected to the tonearm assembly that presses the end of record "lever" on the top of the cam. The service manual identifies this part as the shut off slide. The ball bearing is larger in size and fits in the groove. Photo shows the groove on the arm. The ball bearing is 4mm in diameter. You should be able to see the ball bearing when you remove the platter if I remember correctly. Been few months since I worked on a 1219.
Hope this helps!

that sounds promising, I have been flipping the turntable upside down and right side up quite a bit while I have been diagnosing and testing, so it makes sense this could have come loose. To reinstall, does it just pop into the groove?

thanks so much!
 
Oh darn, I just tried to use the multi-play spindle that came with it. When I switch to multi-play and use the auto start, the tonearm swings over, but when the needle hits the record it just skips at the entry groove. This does not happen when it is switched in the single play setting. Any thoughts? Something must be inhibiting the movement of the tonearm towards the middle of the record, correct?
 
Hmmm - when I resto'd my 1219 like 10 years ago I set it to single play mode and haven't touched that damn lever since. Are you sure you didn't snap one of of the gimbal ears off? One of mine was broken when I got it but I sourced a replacement. And then sourced a spare, just in case.
 
Pretty sure they are still intact, i can see both of them in their respective grooves, I would probably have to fully disassemble it to really make sure. The only thing I can think of is either misadjustment of the black plastic positioning sleeve or the locating screw, at least if you trust the service guide. I really wish they had thought to make figures more relevant to the actual text. Much of the text refers to pieces that are not identified in the included figures, causing you to have to refer to the exploded diagrams alot. Will update with the results later today.

Check page 8 of the service manual. There may be too much friction in the tonearm bearing or the guide needs slight adjustment.

I figured it out! The real problem was a combination of the equalizing arm was not adjusted correctly (and they make no mention of how to adjust it; there is a screw you can turn to allow the balance plate of the main lever to make proper contact with the lift bolt). From there, the positioning sleeve needed to be adjusted to remove the horizontal binding.

Now, finally, the single and multiplay functions work. I'll put a picture of the turntable in all its glory once I can get rid of a white mark I made in the wood of the plinth while trying to steam out a small dent. Thanks Tom! I live in St. Louis too!
