Removing and assembling the gearhead
See the following steps to replace the gearhead or to change the cable outlet position.
Removing the gearhead from the motor
Remove the hexagonal socket head screws (2 places) assembling the motor
and gearhead, and detach the gearhead from the motor.

Assembling the gearhead to the motor
1. Keep the pilot sections of the motor and gearhead in parallel,
and assemble the gearhead with the motor while slowly
rotating it clockwise/counterclockwise.
At this time, note so that the pinion of the motor output shaft
does not hit the side panel or gears of the gearhead strongly.
2. Check no gaps remain between the motor and gearhead, and
tighten them with hexagonal socket head screws (2 pieces).
Assemble the gearhead to the motor in a condition
where the motor output shaft is in an upward direction.

Note
•
Do not forcibly assemble the motor and gearhead. Also, do not let metal objects or other foreign matters
enter the gearhead. The pinion of the motor output shaft or gear may be damaged, resulting in noise or
shorter service life.
•
Do not allow dust to attach to the pilot sections of the motor and gearhead. Also, assemble the motor
and gearhead carefully by not pinching the O-ring at the motor pilot section. If the O-ring is crushed or
severed, grease may leak from the gearhead.
•
The hexagonal socket head screws assembling the motor and gearhead are used to attach the motor and
gearhead temporarily. When installing the product, be sure to use the included hexagonal socket head
screws (4 pieces).
