Need some help please, please, on a Yamaha CD Player model cdc-60. Just replaced the laser unit and it detects the CD and the spindle motor starts up ok. Hit the play button and the unit plays okay for about 15 minutes then starts to slow down, speed generally wanders around and eventually stops and indicates there is no CD present. Is this likely to be a motor problem? If not any hints? This unit is not the best to try and work on as you can't get to anything while the it is playing Thanks for any helpTJB

Try electrically disconnecting the motor (cut trace maybe) and running it,the motor in isolation, from a bench power supply to see if its a bearingproblem.Only low voltage, 1 to 2volts at most usually--Diverse Devices, Southampton, Englandelectronic hints and repair briefs , schematics/manuals list on

I'll just measure it with calipers. I was hoping someone would have the correct measurement from a manual, as I am concerned about the plastic locating lug height being a problem.

Thanks TJB

It's just been my experience. The original was pressed on with a machine. You and I press it on by hand and it doesn't wind up that the disc will rotate quite as flat as the original once the job is done. Like I said, it;s not really a big deal. The focus servo will just have to work a little harder.

Just fitted a new motor. Can't tell if it has more wobble or not. I don't have any way to measure the wobble but from an 'eye ball' point of view, it doesn't seem to spin all that flat, (orig may have been the same). but the focus tracks the cd and the unit plays just fine.

Thanks everyone for your help

Thanks Mark, I still have this uncomfortable feeling about that turntable locating pin. If the laser assembly springs start to sag any cd you play will start to rub on this pin; there seems to be just over

1mm clearance. Oh well I will just have to see what eventuates.

Cheers TJB
