3-8. LOADING MOTOR ASSEMBLY AND
WORM GEAR ASSEMBLY
(See Fig. 3-8-1 )
1) Refer to section 3-2 and remove the mechanism unit.
2) Remove the soldering on the lead wires 2 of the
loading motor assembly from the MC-1 PWB assembly.
When you do this, be careful not to let the soldering iron
touch any other parts.
3) Press the clamp 3, and remove the loading motor
assembly 1 and the damper 4. Be careful not to exert
too much force on the clamp 3.
4) Remove the worm gear assembly 5. To maintain
performance, do not dis-assemble the worm gear
assembly 5.
ASSEMBLY NOTES:
1. Apply grease (SGL-505) to the teeth of the worm gear
assembly.
2. Check that the clamps 3 and 6 are securing the
loading motor assembly.
3. Check the polarity of the lead wires 2 (the orange wire
is the positive terminal, and the gray wire is the nega-
tive terminal). After soldering the lead wires 2, adjust
them so that they do not touch the friction gear assem-
bly.
