Jeff,
Look closely at the gear on the shaft of the tracking motor.
These crack lengthwise and cause your symptom.
I repair them by enlarging the hole through them slightly and re-fitting
with superglue.
Also, make sure the P/U slides REAL easy up and down the shaft. I usually
pull the tracking gear off so I can slide it freely by hand. Quite often
they bind.
Use moly grease and a little machine oil.
They bind together for a good consistency that prevents binding .
BTW, how sure about your spindle motor are you?
I usually pump them full of WD40 and apply about 10-12V in both directions
for a few seconds to clean off the commutator if I'm not replacing them.
I have a manual if you need one.

Subject: [TechAssist] Yamaha CDC-645 CD player Alignment Info needed
Make : Yamaha
Model : CDC-645 5 disk changer
Problem : Reads TOC in a snap and play well but will inadvertently jump
during playback at any random time....may jump back about 20-30 second in a
track or ahead. Lubed everything...no debris in the gears.
Changed the pickup and flushed out the spindle and traverse motor with WD40.
Cables seem Ok going to pickup and motor board......moving them during
playback does not make it act up.
Alignment issue? anyone have the data on this one?
Anything else I might have overlooked?
