I have a Wurlitzer 1100 jukebox that I recently disassembled to replace the 5" fiber gear and degrease the old gummed up oil. I have put the jukebox back together and everything is working as it should. The only issue that I am encountering is that when I make a record selection it is always off by exactly 12. If I choose record selection 1, record tray 13 swings out and plays. Any advice on what adjustment I need to make would be appreciated. I have the Wulitzer 1100 service manual and have not been able to locate the information for this adjustment. Thanks.
