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 eccelen{riclty.
●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 (C M3-2) and new special
washer (C M3-4) for replacement. CM3-2
The removed turntable will be deformed by the heat of the
soldering iron, and cannot be reused. CM3-1
.Prepare dial type calipers.
(l) 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.
(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 CM3-5
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 2015F” 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
(l) 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
voltmeter. 10 kohm

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 pickupp,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) Disconnect the socket (for the sled motor power supply) (1) Remove the two screw (CY1) and remove the sled motor
from the P. W. Board. (CM5).
(2) Apply avoltage of DC 2.0 Vto the sled motor’s terminal. CY1
(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. CM3-1 –
(4) The current during sled motor action varies according to
the positional relatlonshiping of gears (CM7 and CM8).
(5) If the current exceeds 40 mA, remove the gears (CM7 and
e
,“
CM8). CM5 ““”
(6) Apply asmall amount of aFLOIL (G-474B) bonding ma[eri-
als to the chassis shafts.

REPLACE ME NT OF CD MECHANISM
6. Resetting the pickup to the home position
(l) The Iimlt switch is switched ON by the projection of ttlis
rack gear secured to the returned pickup, after which Lhe
sieci motor continues to operate (by the circuit )for ap-
proximately 30 rnsec. :there is then again areverse opera-
tion, and m~vement to the position at which ttle 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. (
