Sur un autre forum, il y avait ce problème de posé. ça ressemble au tien, non ?
C'est en anglais mais bon..
question:
I picked up a beater Zero 92 for playing 45s and 78s. The good news was the grease was still fairly greasy, although a bit gummy, and the idler was in great shape. The tone arm seems good to go as well, in its complicated way. I did the usual clean, grease and oil of the mechanicals before I even plugged it in.
The problem was the motor - it grunts and groans along, barely turning the spindle for the idler wheel. It has a rattling sound to it while on. I had the platter off, and the idler off the spindle and it is the motor. I have run into all kinds of goofy things with old Garrards, and don't think I have ever seen one of the motors go haywire before. But I am game for anything, so I am willing to take the motor out and strip it down to lube it or look for something bad. But I have never done that before and am curious for how to go about it. Is there a service manual out there that tells you, or has anyone got a good idea of what is going wrong here? Always appreciate the help here. Thanks!
réponse :
The central rotor of the Synchro Lab Motor is a two part device with two magnets stuck together. I serviced a Zero 100SB for a friend which exhibited the same symptoms that you are describing and it turns out that the two parts had become unstuck, so the motor was still working but rattling like a good 'un!
All i needed to do was stick the two parts back together and everything was fine again.
To remove the motor, you need to remove the turntable platter and remove the 3 circlips from the rubber isolation mounts, then the motor will pull out underneath the deck. Once done, there are two long screws on the bottom face of the motor which, when undone, will let the motor assembly pull apart, separating bottom bracket, top bracket and main body. You will need to remove the pulley with a very small screwdriver and the rotor assembly will just drop out. Glue the two bits back together, clean everything with isopropryl alcohol, lubricate the bottom and top bearings with some fine oil, put back together, and enjoy for the next 25 years........
