Note
On rare occasions, grease may ooze out from the gearhead. If there
is a concern over possible environmental damage resulting from the
leakage of grease, provide an oil tray or similar oil catching mechanism
in order not to cause a secondary damage. Grease leakage may lead to
problems in the customer's equipment or products.

Note
Do not install the motor to the mounting hole diagonally or assemble
the motor forcibly. Doing so may cause damage to the motor.
z

Removing and assembling the gearhead and the decimal gearhead
See the following steps to replace the gearhead or to change the outlet position of
the lead wires and the position of the terminal box.
Removing the gearhead from the motor
Remove the hexagonal socket head screws (2 places)
assembling the motor, gearhead and decimal
gearhead, and detach the gearhead and decimal
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).
When using a decimal gearhead,
install it between the motor and the
gearhead.

Note
•
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.
•
O-rings are attached on the motor flange and the mounting surface
of the decimal gearhead. Install the gearhead so as not to pinch the
O-rings. Grease in the gearhead may leak.
z
Round shaft type
Secure the motor with hexagonal socket head screws (not supplied) through the
four mounting holes provided. Do not leave a gap between the motor and mounting
plate.

Motor with cooling fan
When installing a motor with cooling fan onto a device, leave 10 mm (0.39 in.) or
more behind the fan cover or open a ventilation hole so that the cooling inlet on the
back of the motor cover is not blocked.
z
Mounting the capacitor
Mount the capacitor securely by using M4 screws (not
provided).
Ø4.3 mm
(0.169 in.)
Note
•
Do not let the screw fastening torque exceed 1 N·m (8.8 lb-in) to
prevent damage to the mounting foot.
•
Mount capacitor at least 10 cm (3.94 in.) away from the motor. If it
is located closer, the life of the capacitor will be shortened.
Installing a load
The gearhead shaft is provided with a key slot for
connecting the transmission parts. When connecting
the transmission parts, ensure that the shaft and parts
have a clearance fit, and always fix the parallel key
to the output shaft with a screw to prevent the parts
from rattling or spinning.

Note
Do not apply excessive force onto the output shaft of the gearhead
using a hammer or other tools. Doing so may cause damage to the
output shaft or bearings.
