Disassembly/Assembly
[Rear side of motor holder]
The motor holder is fixed by the two
screws and claw
B
at the rear. To
remove it, push claw B in the direction
of the arrow from the rear of the
chassis. Note that positioning pins
D
are easy to break when attaching the
motor holder. Apply grease (half size
of one grain of rice) to the two
parts shown in the right figure.
[Front side of motor holder]
While spreading claws
A in the
direction of the arrow, pull out the cam
motor upward. To attach it, push the
cam motor into the motor holder and
route the two wires of the cam motor
into claw
C .
When attaching the TG2 control arm,
claw
E must be inserted into the hole
of the TG2 control arm.
Checks before disassembly and assembly
The cam motor is fixed on the motor holder by the four
claws. Releasing the four claws enables the cam motor to
be removed without removing the motor holder from the
chassis. When attaching the cam motor, be careful of the
assembling direction (the label must face toward the front).
If the phase of the gear, etc. moves when removing the
motor holder, refer to page 5-40.
