This repair is a Mechanism from a Rock Ola Nostalgia "Bubbler" CD Jukebox made in 2005. The grease on the gripper arm turned to hard paste. This hard paste caused the outside gear to break a tooth. We opted not to pick up the whole machine because of the fragile nature of Bubbler tubes. We have broken them before while transporting the machine on a pickup truck. We took it completely apart and re-greased the whole unit. Replaced the 2 gears and tested the motors manually. Also tested the CD player in another jukebox. Took it back and made final adjustments in the machine.
