Actually I did replace the bushes when I rebuilt the motor Davy. Had some left over from a jukebox rebuild where they supported the turntable motor. What seems to happen with mine is that the mechanism seizes – locks solid. Fiddling with the actuating rods to one or both spindles gets it going again. Hasn’t done it for some time now and all is well lubricated so I hope it has recovered. I’m certainly not going to dismantle anything until it happens again………
