Spacer doesn't work
A spacer prevents the CD from being positively centered, so it would be liable to wobbling, making it difficult to track. I wanted to see if I could refrain from using a tighter belt to avoid putting too much pressure on the bearings in the motor. I'm in the US and O-rings at the local Ace hardware are not designated by number so I will have to see what matches the drive belt.

Someone on another site had this to say about D701: "It seems that these players have a construction flaw. Look for D701 on the main board -- near the cables that run to CD transport. You will find in that place a small 7.5 kOhm rsistor. This should be a 6.2 Volts Zener diode instead. Replace the resistor with 6.2 V Zener and the tray becomes strong and fast."

I don't see how this is possible because the problem is not the motor, which is the only thing that could be affected by the D701 component, whatever it is supposed to be. The problem is that the magnet is too strong for the belt/linkage to break the magnetic bond of the the upper and lower clamps of the CD spindle. As everyone who has this problem knows, the motor can be heard spinning when the door does not open.
In short, I believe the only solution is a slightly tighter belt.
