REPLACEMENT OF CD MECHANISM
●
●
●
Note that the mechanism of the CD p!ayer 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~e
tracked), as well as the gear and
other components, operate srmooth[y, without eccelentrlcity.
When handling the pickup, take care not io 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 reimoved turntable will be deformed by the heat of the
soldering iron, and cannot be reused.
.
. Prepare dial type calipers.
(l) The attached bonding material can be dissolved by using a
60 W soldering iron to heat the shaft at the under part of
:~&
the iurniable (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
v
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.
I (5) Apply a small amount of a mixture of
the “Three Bond
2001 and 2015F” bonding materials to the
molor’s shaft.
(6) Initial the turntable as shown in the figure. Secure ihe iurn-
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 mater Ial
at the top of ;haft.

(l) Connect the digital voltmeter as shown in the figure.
(2) Set the test

PLAY button (Playback for the most inner music).
(3)At this time, record voltage value to indicaie at the digital
voltmeter.
(4) Access the most outer music,
press the PLAY button
(Playback

(5) Again at this time, record vollage value to ind!cate at the
digital voltmeter.
Be sure to wipe away
the bonding material.

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 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 ap-
plying the grease, do not allow any grease to adhere to
any other parts.
(3) Pass the a pickup rail (CfV?2) 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.

(3) Measure the current during sled motor operation.
. The direction of movement of the pickup (Outer groove or

/
ity.

REPLACEMENT OF CD MECHANISM
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 ap-
proximately 30 msec. : there is then again a reverse 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.
