REPLACEMENT OF CD MECHANISM
l Note that the mechanism of the CD player is very delicate.
l It is very important that the spindle motor (witch 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 eccentricity.
l 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.
a. Replacement of the spindle motor
l First, prepare the new turntable (CM1 -2) and new special washer

(CMI-4) for replacement.
The removed turntable will be deformed by the heat of the
soldering iron, and cannot be reused.
Prepare dial type calipers.
The attached bonding material can be dissolved by using a
60W soldering iron to heat the shaft at the under part of the
turntable (CMl-2) 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 (CM1 -3) and remove the spindle motor
(CMl-5).
Attach the special washer (CMI-4) to the spindle motor.
Apply a small amount of a mixture of the “Three Bond 2001
and 2015F” bonding materials to the motor’s shaft.
Initial the turntable as shown in the figure. Secure the turntable
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.

REPLACEMENT OF CD MECHANISM
c. Replacement and lubrication of the pickup
l Before replacement of the pickup, be sure to carefully read the
section regarding the pickup when the unit is moved or
transported.

(3)
.
.
Remove a pickup rail (CM2) with a driver from the bottom of
chassis.
When removing or inserting the pickup rail from or into chassis,
take care not to exert excessive force.
When the pickup is reconditioned of replaced, be sure to wipe
the rails clean and also apply a coating of FLOIL (G-4748) to
there entire circumference and entire length.
When applying the grease, do not allow any grease to adhere
to any other parts.
Pass the pickup rail (CM2) through the new pickup (CM7).
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 replaced.

d. Checking the action of the CD mechanism
e. Replacement of the sled motor
(1) Disconnect the socket (for the sled motor power supply) from (1) Remove two screw (CYl) and remove the sled motor (CM3).
the P.W.Board.
(2) Apply a voltage of DC 2.OV to the sled motor’s terminal.
(3) Measure the current during sled motor operation.
l The direction of movement of the pickup (outer groove or inner
groove) can changed by changing the battery polarity.
(4) The current during sled motor action varies according to the
positional relationship of gear (CM5, CM6).
(5) If the current exceeds 40mA, remove the gears (CM5, CM6).
(6) Apply a small amount of a FLOIL (G-4748) bonding materials
to the shaft.

REPLACEMENT OF CD MECHANISM
f. 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 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 during about 30 msec, after the switch is
switched OFF. And then the pickup stops at home position.
