REPLACEMENT OF CD MECHANISM
. Note that the mechanism of the CD player is very delicate.
&
. It is very important that the spindle motor (which rotates the disc), and the sled motor (which cases the disc signak to be
tracked), as well as the gear and other components, operate smoothly, without eccelentricity.
● When handling the pickup, take care not to exert excessive force, and particular care should be taken not to touch the lens
or the drive circuit’s P. W. Board pattern.
1. Replacement of the spindle motor
● first, prepare the new turntable (CM3-2) and new special
washer (CM3-4) 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 at the under part of
the turntable (CM3-2) for about one minute.
(2) 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.
(3) Remove the two screws (CM3-3) and remove the spindle
motor (CM3-5).
, (4) Attach the special washer (CM3-4) to the spindle motor.
(5) Apply a small amount of a mixture of the “Three Bond
2001 and 201 5F” bonding materials to the motor’s shaft.
(6) Initial the turntable as shown in
the figure. Secure the turn-
table by pressing gently. Be sure
to wipe away (by using a
price of cloth, or similar material) any bonding material
coming out of the hole.
Don’t attached bonding material
at the top of ~ft.

2. Confirm of inclination for the turntable
(1)
Connect the digital voltmeter as shown in the figure.
(2) Set the test disc (YEDS 18 = SONY or etc.), press the
PLAY button (Playback for the most inner music).
(3)At this time, record voltage value to indicate at the digital
voltmeter.
(4) Access the most outer music, press the
PLAY button
(Playback
for the most outer music).
(5) Again at this time, record voltage value to indicate at the
digital voltmeter.
(6) For reference at the recorded voltage of the most inner
music, Confirm at ~ 300 mV less than for recorded voltage
of the most outer music .

3. Replacement and lubrication of the pickup
● Before replacement of the pickup, be sure to carefuily read
the section regarding the pickup when the unit is moved or
transported.
(1) Remove the a pickup rail (CM2) with care fixing the latch
with way driver from bottom part of chassis (CM3-1 ).
(2)The pickup (CM9) can now be remove once the a pickup
rail (CM2) have been taken out.
. When removing or inserting the a pickup rail from or into
chassis, take care not to exert excessive force.
● If the pickup is reconditioned of replaced, be sure to wipe
the rails clean and also apply a coating of FLOIL (G-474B)
to there entire circumference and entire length. When applying the grease, do not allow any grease to adhere to
any other parts.
(3) Pass the a pickup rail (CM2) through the new pick up
(CM9).
. The pickup P. W. Board pattern is ‘shorted”, as shown in
the figure, so that the new pickup wiil not be susceptible
to the effects of static.
. Set the pattern to “open” after the pickup has been re-
placed.

5. Replacement of the sled motor
(1) Disconnect the socket (for the sled motor power supply) (1) Remove the two screw (C’f%) and remove the sled mote
from the P. W. Board.
(CM5).
(2) Apply a voltage of DC 2.0
V to the sled motor’s terminal.
(3) Measure the current during
sled motor operation.
. The direction of movement of the pickup (outer groove or
inner groove) can changed by changing the battery polarity.
CM3-1
(4)
The current during sled motor action varies according to
the positional relationshiping of gears (CM7 and CM8).
(5) If the current exceeds 40
mA, remove the gears (CM7 and
8
k
CM8).

6. Resetting the pickup to the home position
(l) The limit switch is switched ON by the projection of this
rack gear secured to the returned pickup, after which the
sled motor continues to operate (by the circuit ) for approximately 30 msec. : there is then again a
reverse operation, and movement to the position at which the switch is
switched
OFF.
(2) Rotation continues for about 30 msec. after the switch is
switched
OFF, and then the pickup stop at home position.
