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 5-11.
Note: Do not hold the shaft when selecting the reels.
