Seeburg B Sides Wont Reject

OK, I think this is a simple one, I just can't figure out exactly which contact is having the problem. I think I've FINALLY found something not covered in Ron's troubleshooting guide, too! (although I'm also positive I didn't and Ron will let me know :wink: )

Can anyone help me identify which switch would cause this:

A-sides work perfect. B sides will play the whole record, then when it rejects, the needle comes off the record, but then the record wont reject...I just get "click click click" because I think a contact somewhere isn't fully making contact to complete the next step.

I suspect it must be in the reversing switch since it's only a problem on one side. I've double checked the switches and cleaned them well. They all seem to be making contact as they should.

Since I'm feeling fancy, here's some video! https://www.youtube.com/watch?v=Tw9vukW2WVE

Bucking clutch -(yes, I meant bucking) Since the greatest strain occurs as the clamp is opened a worn clutch member will pop out of it's notches.

One test: Press down on that manual trip level at that point. It should force the clutch to hold briefly, open the clamp and go back into scan. This is one case where it --may-- be possible to cure be redoing the four clutch adjustments. Otherwise a thorough lube and cross your fingers.

BTW: What model?

Rob,
No--that's not covered in the MicroLog Trouble Shooting Guide. As I did not cover the mech in that guide--it is more, or less in the Mechanism Guide--IF, your mech is PROPERLY oiled, check the thrust bearing adjustment on top of the clutch housing, before doing any "adjusting--" Ron Rich

That is a good point about the top bearing on the clutch. I'd forgotten about that one.

BTW: I notice that Jukebox-List has disappeared without a trace -even the archive is gone.

Very interesting guys, thanks! A couple followup questions (it's an LS325, btw):

1. Just to be very clear: this wasn't happening until I made some changes (see 2) and this is only happening on B-sides and only during reject. Everything else works fine. Would a mis-adjusted clutch really only affect this? I believe you, just trying to understand why it wouldn't affect any other functions.

2. As you may remember I just replaced driveline rubber and found that there was no rubber 'base' before (under the motor). So obviously I added one. Would this additional 'squeeze' (additional height) be what would have altered this clutch functionality? So now I have to readjust for additional height in the driveline by altering the clutch setting? (I'll have a go in the service manual to locate and see how to adjust the thrust bearing)

Rob,
IF, you had purchased, and READ, my "Seeburg Mechanism Guide", you might understand that once the trip solenoid is energized, all functions are mechanical. "Cleaning the Reversing Switch Contacts" is a waste of time, in this case.
There is no relationship between the clutch thrust bearing, and the motor---See the SERVICE manual--

Still feeling my way through these things, Ron. I'd like to support you as much as I can but I just can't afford to buy every manual for every problem. That's why I'm on forums for video games, pinballs, coke machines, and, yes, jukeboxes. It's really the modern (and free!) way to find info on all these hobbies...in my experience thats what these forums are HERE for!

I truly appreciate the service you provide, Ron, and I'll support it as much as I can, but I am not looking to become an expert and am not looking to spend a bunch of money on guides (that I mostly dont understand anyway)...just get my box running as well as possible and learn along the way.

Since you sell your guides, Ron, please dont feel obligated to give free answers (although of course I really appreciate them!)...I'm happy to learn from others as well!

Hi Rob,
I understand--I can not afford to give them away ! I wrote the two guides to help people, not to "make money" (I have done that for almost 50 years, now, by repairing them !)--I have yet to really, "get out of the hole" on guides, after 12 years ! (close, several times, till I needed to have more printed). In the Mechanism Guide, I attempted to explain all of the mechanism's functions, and how it works. I have found, over the years, that I can fix "anything", if I understand what it SHOULD do, when !--I kept this in mind while writing that guide. I also now see there is so much "poor", and/or, "incorrect" information, "out there" (unfortunately, at times, also here on "PhonoLand"), that people follow, which causes un-necessary damage to the phonographs--besides, it wastes time !

I've been in this community a VERY short time and it was immediately obvious how much you give back, Ron, so I have nothing but gratitude!

Now, back to the problem at hand, I realized WHY I thought it was a contact issue in the reversing switch:

When it hits this glitch (shown in the previous video) and won't reject, there's one way to get it to reject: I manually flip the reversing switch the other way and it rejects the record.

Just want to make sure that fact doesn't change any minds about the fix.

Rob,
I am ASSUMING, that the thrust bearing on top of the clutch has too much clearance, or, worn out/missing the ball, on either end.
I am 99.9% positive, it is a mechanical problem--

Thanks Ron, will go over this tonight. As you may remember, this problem didn't exist before I replaced my driveline rubber, so I'm certain it's just an adjustment...not missing parts.

So, I'll dig in, thanks!

Rob,
Once again--the "driveline", has NO relationship, to the clutch shaft ! See the Service Manual--

Oh, I see...I didn't understand that point before, thanks for diving it home again. It sure seems to have started at the same time, so maybe just a coincidence. Thanks for clearing that up.

I totally forgot to reply to this and say that, as always, Ron was right :) I made the suggested adjustment and I'm rockin' and rollin again.

Thanks for all you do Ron (and Rob NYC!)..for the first time, my box is working 100% thanks to all your help!!
