a. INSTALLING THE DISC TRAY

Turn the pick-up sled gear (13) in the direction of the arrow. (①)
(2) Align the disc tray with the mechanism chassis.
(3) While pressing down on the disc tray, check that the tray move gear (3) and disc tray interlock, as shown in the figure. (2)
(4) After the disc tray has been housed, place the screw at the back left screw of the disc tray. (③)

b. DISASSEMBLY OF THE CD PLAYER MECHANISM

(a) Replacement of the spindle motor

First, prepare the new turntable (50 2) and new special washer (50 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 upper part of the turntable 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 ( 50 5 ) and remove the spindle motor (50 - 3).
(4) Attach the special washer (50 4) to the spindle motor.
(5) Clean the spindle motor's shaft.To clean them, use a soft cloth soaked in isopropyl alcohol.
(6) Apply a small amount of a mixture of the "Three Bond 2001" and "2015F" bonding materials to the motor's shaft.
(7) Install the turntable as shown in the figure.
(8) Secure the turntable by pressing gently.

Be sure to wipe away (by using a piece of cloth, or similar material) any bonding material coming out of the hole.

Don't attached bonding material at the top of shaft.

Be sure to wipe away the bonding material CHUCK PULLEY

(b) Replacing the pick-up

(1) Insert the pick-up rails (35) from an angle of 45° into the base chassis (50).

(2) If the laches (x 2) of the base chassis (50 1) are missing when the pick-up rails have been installed, first wipe the tips of the rails with alcohol and then secure them with adhesive (Cemedine #575)., as shown in the figure.
(3) After the pick-up has been replaced, apply grease (FLOIL G-474B) to the areas marked with an arrow.
(4) The pick-up P.W.Board pattern is "shorted", as shown in the figure on the right, so that the new pick-up will not be susceptible to the effects of static.
(5) Set the pattern to "open" after the pick-up has been replaced.

Page 4

(c) Replacing the sled motor

(1) Remove the screw (25) securing the motor.
(2) Disengage the two tabs on the chassis which lock the bottom of the sled motor (48).
(3) Replace the motor (48).

(d) Checking the operation of the CD mechanism

Check the following operations with the disc tray removed.

The direction of movement of the pick-up (outer groove or inner groove) can be changed by changing the battery polarity.
Disconnect the power socket of the sled motor from the P.W.Board.
(2) Supply a DC 0.6V voltage to the sled motor terminals.
(3) Check that the pick-up moves smoothly from the inner toward the outer grooves.
(4) Reverse the battery polarities and check that the pick-up moves from outer toward the inner grooves.
(5) Supply a DC 4V voltage to the sled motor terminals.
(6) The clutch outer gear (9) slips after loading.
(7) Check now that the sled motor current is 120 mA or more.
(8) Reverse the battery polarities.
(9) The clutch outer gear (9) slips after loading.Check now that the sled motor current is 120 mA or more.

(d) Applying grease to the base lever (45)

Apply (FLOIL G-474B) to the base lever (45), as shown in the figure on the right.

(e) Spring (51) for holding up the base chassis
First secure the spring for holding up the base chassis as shown in the figure on the right, and then apply adhesive (Cemedine #575) both above and below.

(f) Applying grease
(1) Apply grease (FLOIL G-474B) over the entire circumference of the pick-up sled gear (13), as shown in the figure.
(2) Apply a little grease (G-333) to the outside of the clutch outer gear (9).
(3) Apply grease (FLOIL G-474B) to the clutch outer gear (9), as shown in the figure on the right.

Page 7

(g) Positioning the CD mechanism leads

Bend the mechanism leads around the parts, as shown in the figure.
(2) Ensure that the leads will not stick up at any point.

(h) Positioning the pick-up leads

(1) Arrange the pick-up lead wires as shown illustration.
(2) If the pick-up is reconditioned or replaced, be sure to wipe the rails clean and also apply a coating of FLOIL (G-474B) to their entire circumference and entire length.
(3) Apply adhesive (Cemedine #575) to the outlets of the connectors.
