Removing/Installing the gearhead
To replace the gearhead or change the cable outlet direction, remove the screws assembling the gearhead.
The gearhead can be removed and the motor cable position changed to one of three 90° directions.
Note that the motor cable cannot be positioned in the direction where the cable faces the gearhead output shaft.
1.
Remove the hexagonal socket head screws (4 pcs.) attaching the gearhead and motor and detach the
motor from the gearhead.

2.
Using the pilot sections of the motor and gearhead as guides, install the motor to the gearhead and
tighten the hexagonal socket head screws.
At this time, the motor cable position can be changed to one of three 90° directions.
Install the motor carefully to prevent the pinion of the motor output shaft from contacting the casing or gear of the
gearhead.
Also conrm that no gaps remain between the motor ange surface and the end face of the gearhead’s pilot
section.
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 or gear of the motor output shaft 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 carefully by not pinching the O-ring at the motor’s pilot section. If the O-ring is
pinched, the coupling strength will drop and grease may leak from the gearhead.
•
The motor cable position cannot be changed to the direction where the cable faces the
gearhead output shaft, because the gearhead case will obstruct the cable.
