2. CD MECHANISM
(1) Replacement of the spindle motor
● First, prepare the new turntable and new special washer for
replacement. The removed turntable will be deformed by
the heat of the soldering iron, and cannot be reused.
● Prepare dial-type calipers.
1. The attached bonding material can be dissolved by using a

60 W soldering iron to heat the shaft the upper part of the
turntable for about one minute.
The turntable can then be removed from the shaft by very
carefully applying force upward at the center of the lower
surface of the turntable.
Remove the two screws and remove the spindle motor.
Attach the special washer top the spindle motor.
Clean the spindle motor’s shaft. To clean them, use a soft
cloth soaked in isopropyl alcohol.
Apply a small amount of a mixture of the “ Three bond
2001” and “201 5F” bonding materials to the motor’s shaft.
Install the turntable as shown in the
figure.
Secure the turntable by pressing gently. Be sure to wipe
away (by using a piece of cloth, or similar material) any
bonding material coming out of the hole.
(2) Replacing the pick-up
1.
2.
3.
4.
Insert the pick-up rail into the base chassis.
If the rack of the base chassis are missing when the pick-up
rail have been installed, first wipe the tips of the rail with
alcohol.
After the pick-up has been replaced, apply grease (FLOIL
G-474B) to the - sections.
The pick-up P.W. Board pattern is “shorted”, as shown in
the figure, so that the new pick-up will not be susceptible to
the effects of static.
Set the pattern to “open” after the pick-up has been
replaced.
