Heres a mechanism out of a Seeburg model G that was pulled out of the jukebox for a clutch repair, its not uncommon after many years of service that the old grease and lube dries up on the moving parts, and causes such problems as the machine feeding a record out to play and returning it to its slot over and over without ever playing the record.
Here is the record mechanism out of a rare seeburg sx100 jukebox.
This mech was sitting to long without use and the old factory grease dried up which cause the cluth to stick.
A Seeburg STD4 Madri Gras Jukebox
This machine was a workhorse back in the 1970s in the Bars and Resturants before it was replaced in the 1980s with CD Jukeboxes
