Removing and assembling the gearhead
See the following steps to replace the gearhead or to change the cable outlet position.
Note that the motor cable cannot be positioned in the direction where it faces to the gearhead output shaft side.
Removing the gearhead from the motor
Remove the hexagonal socket head screws (4 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
(4pieces).
Change the cable position
to a desired 90° 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 motor cable position cannot be changed to the direction where the cable faces the gearhead output
shaft. The gearhead case will obstruct the cable.
