Step 1
• Attach a key to the motor shaft.
Step 2
• Attach the input gear to the motor shaft.
• Check that there is no foreign matter adhering to the mounting surface.
If there is foreign matter adhering to the mounting surface, appropriate installation accuracy cannot
be obtained. It could cause deterioration of performance, such as abnormal noise and vibration, and
also lead to damage of the motor.
Step 3
• Fix the input gear to the motor shaft using a hexagon socket head cap screw.
• Using a thread-locking sealant for screws, lock the hexagon socket head cap screw.
If necessary, seal the area with a seal washer, etc. Otherwise, it could cause the leakage of
lubricant.
Check the depths of the input spline hole and motor shaft screw before selecting an appropriate size
and length of the hexagon socket head cap screw.
