Any help is appreciated, I am truly stuck and need some real knowledge about the main clutch and it's part setup that is not shown to well in the LPC1 manual on page 2477. Mechanism wont scan left after playing a record from right to left. It is a type 133S1. The clutch is free and moving well. The mechanism does everything well except when the clutch member is dropped to engage with the track sprocket. The "clutch engaging member" piece doesn't line up correctly with clutch and prevents the clutch from lining up with the sprockets' gold notch. The "clutch engaging member" holds up the clutch with it's key'ing just enough so the clutch does not engage the sprocket and its gold notch. I have to take a screw drive and line up the "clutch engaging member's" key with the clutch. Once the Key on the "clutch engaging member" lines up with the clutch's key the whole thing falls together and starts scanning again. I have done adjustment of the four clutches. I found the clutch engaging member spring off of the "clutch engaging member". Does anyone know how exactly the spring sets on the sprocket? Does the little lop on the spring go around the sprocket's gold knotch? Does the spring wrap around the knotch and the "clutch engaging member"? Does the spring go in the little channel around the "clutch engaging member" and then also around the sprocket gold knotch with it's little loop? I have removed it and replaced it many times and nothing seems to fix this problem. I need a definite on how the spring goes into place. I also need to know why the "clutch engaging member" wont let the clutch down fully. It has alot of play in it but nothing looks bent or damaged. It has a slot cut in it on either side so it can give some room for the pins but it is loose. When it scans from left to right and puts a record back it works. It drops right into scan when done. When it scans right to left and ends it doesn't work and the clutch just gets stuck on the "clutch engaging member" part. It looks like a spacer that is keyed. thanks for any help. This was one ruff jukebox.
 
Thank you Ken, I already have a response to a post I just put up on phonoland that could solve my problem. It could be a resistor that could be open on the reverse switch. Evidently this jukebox is supposed to pick up records only one way scanning not both. The resistor could be bad letting the mechanism pick up records on the return. Of which it is not designed to do. Going to check it tonight. Thanks again for pointing me in the right direction.
 
Ron Rich over at phonoland wrote a book on Seeburg mechanisms. He really knows his stuff.

Back in early April this year we lost _THE_ foremost Seeburg expert, Tony Miller. He worked at the factory and designed some of the later 45 machines in the early 1970's. His tech website is still up (running on autopilot) but I don't know how long it will be there.

Strongly suggested to check out everything there and save as much as you can.

Ron Rich is now our best Seeburg expert.
 
Thank you.

I got the jukebox to work correctly now. I didn't have to replace the resistor. I just cleaned off the contact point and installed the spring pin back the way I thought it would go together and it works!! Now I have to figure out why it stops playing a record when a new selection is made during playing. I also cut and pasted pratically the the whole Tony Miller web site. Thank you for that link. Sorry to hear he past away. thanks again for all your help. Joe
