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 signals to be
tracked), as well as the gear and other components, operate smoothly, without eccelentricity.
●When harldlirlgthepickup, 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. CM3-2
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 Wsoldering iron to heat the shaft at the under part of
the turntable (CM3-2) for about one minute.
~l##& -
(2) The turntable can then be removed from the shaft by very ----
carefully applying torte 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 asmall amount of amixture 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.

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). F+ +
(3)At this time, record voltage value to indicate at the digital .

REPLACEMENT OF CD MECHANISM
.- 3. Replacement and lubrication of the pickup
●Before replacement of the pickup, be sure to carefully read
the section regarding the pickup when the unit is moved or
transported.
(1) Remove the apickup 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 apickup
rail (CM2) have been taken out.
●When removing or inserting the apickup 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 acoating of FLOIL (G-474B)
to there entire circumference and entire length. When ap-
plying the grease, do not allow any grease to adhere to
any other parts.
(3) Pass the apickup 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 will not be susceptible
to the effects of static.
●Set the pattern to “’open” after the pickup has been re-
placed.

4. Checking the action of the CD mechanism 5. Replacement of the sled motor
(1) Disconn~ct the socket (for the sled motor power supply) (1) Remove the two screw (CYI )and remove the sled motor
. .from the P. W. Board. (CM5).
(2) APPIY avoltage of DC 2.0 Vto 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 polar-
ity.
(4) The current during sled motor action varies according to CM3-1
the positional relationshiping of gears (CM7 and CM8).
(5) If the current exceeds 40 mA, remove the gears (CM7 and
CM8).
(6) APPIY asmall amount of aFLOIL (G-474B) bonding materi-
als to the chassis shafts.

REPLACEMENT OF CD MECHANISM
6. Resetting the pickup to the home position
(1) 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 ap-
proximately 30 msec. :there is then again areverse opera-
tion, 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.

(2) OSCILLOSCOPE :SS5711 (10 MHz and Dual Phenomenon)
NOTE :CD section of this unit can not need adjustment, because CD Section P. W. Board checked at automatic checker.
2. Confirm of general operation
(l) Set the test disc.
(2) Press the PLAY button, then confirm the disc rotating to clockwise direction.
(3) Press the FFWD or REW button, then confirm the most inner music or most outer music accessing at speedy.
(4) Press the STOP button

3. Confirm of eye pattern
(1)
Connect an oscilloscope to pin 41 (RF) of [Cl 01 and VR
point.
(2) Set the test disc, press the PLAY button.
(3) Check to be sure that the “eye” pattern is at center of
waveform and that the diamond shape is clearly defined.
