
When a liquid sealant is used, if the leaking liquid sealant enters the reduction gear, it could cause
deterioration of performance, such as abnormal noise, vibration, and torque irregularity. Also, if the
liquid sealant adheres to the lip of the oil seal, it could cause leakage of the lubricant.

When a liquid sealant is used, if it leaks into the case mounting bolt section, it could deteriorate the
bolt tightening force, and eventually result in deterioration of the transmission torque.

When a liquid sealant is used, follow the instructions of the detailed coating method given by the
manufacturer of the sealant to be used.
• Rotate the shaft to fit the case installation

component into the case mounting hole.
• Align the mounting holes of the motor
mounting flange with the mounting holes of the
reduction gear (case section) and positions of
the tapped holes for the case installation
component, and then attach the motor
mounting flange to the reduction gear.
• Take extra care so that the O-ring is not caught
by the mating section.
• Confirm that the centering shaft of the
reduction gear (case section) is correctly fitted
into the centering hole of the motor mounting
flange.
• Check that there is no foreign matter adhering
to the mounting surface.

If the O-ring is caught by the mating section, it could cause leakage of the lubricant.

If there is foreign matter adhering to the mounting surface, the mounting surface of the reduction
gear may be deformed, which could cause deterioration of performance, such as abnormal noise
and torque irregularity, and durability.

The shape of the motor mounting flange may differ from the illustration above, depending on the
customer’s equipment or shape of the reduction gear.
• Temporarily tighten the hexagon socket head cap screw attached with a serrated lock washer. Step 6
• After confirming that the case of the reduction gear turns smoothly with an average torque, further
tighten the hexagon socket head cap screw with the specified torque. (Another method is to turn the
case using the input gear or dummy input gear.)
