I was directed to this web site for some help with a abused LPC1 Seeburg Jukebox. 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 a good 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.

Joe,
Sounds like that unit is working perfectly, mechanically. It is designed to detent only when scanning from left to right. If it's detenting going from right to left, it's an electrical problem. Most likely, the resistor that's located on or very near (depending on production run), the reversing switch has "opened". See the schematic, or a copy of my "Seeburg Mechanism Guide" for the value--I don't recall at this point, and can not look it up at the moment-- Ron Rich

The more I think about it the more this makes sense and I feel a glimer of hope. It works one way but not the other. It doesn't look damaged or badly worn and I have set everything(clutches and all adjustments) the best I can. Mechanically the clutch engaging member does seem designed to align its' key on one side. I didn't realize this unit detents only one way. Most of my jukebox experience is with older units like the M100Cs from happy days that detent both scanning ways to play both B and A sides and don't even have a clutch engaging member and pin/spring to speak of. I know, I looked on those parts break down sheets also. So this solution is holding merit. I can easly find that resistor by the reversing switch and I have the schematics. The question is can I get to it without removing the whole carraige, again. I think so if it is on the front. SO, I will try that ASAP and will post if it works or not. I first have to put back in the spring pin. Am I safe to assume the pin wraps around the sprocket notch and the channel around the clutch engaging member and not under it? Thanks again for your help. This maybe solution would have never been thought of. I will post what happens no matter what. Joe

I am not 100% sure of what "pin" you are asking about--if it's the one under the clutch member it "snaps" onto the clutch engaging member--see the "Lubrication Guide" for a drawing.

IT WORKS!!! I put the spring pin back in the way I thought it should go and I then checked the big block resistor in front. It was good, but I cleaned the connection to where it goes to chassis. Then I tried it and it works!!! You are correct that it only picks up records from left to right not right to left. I made that mistake because I would trip it manually going the wrong scanning way. So it works pretty good and my friend is happy. Thank you for your help. I know this one will be around for ever now as to it being parted out. Thanks again! Joe

Joe,
Glad you got it !--You are welcome ! Ron Rich
