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 W soldering 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 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.

.- 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 (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 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 polar-ity.

(4) The current during sled motor action varies according toCM3-1

the positional relationshiping of gears (CM7 and CM8).

(5) If the current exceeds 40 mA, remove the gears (CM7 and

CM8).

(6) APPIY a small amount of a FLOIL (G-474B) bonding materi-als to the chassis shafts.

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 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.
