Removing and assembling the gearhead
See the following steps to replace the gearhead or to change the cable outlet position.
1. 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.

2. 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.

Assemble the gearhead to the motor in a condition
where the motor output shaft is set upward.
2) Check that there is no gap between the motor and the gearhead, and tighten them with hexagonal socket
head screws (2 places).

Do not forcibly assemble the motor and gearhead. Also, prevent metal objects or foreign substances from
entering in 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.
