Chapter 5 Installation

If a coating is not applied at some points within the coating range, it could cause leakage of the
lubricant.
When a liquid sealant is used, if it leaks into 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 shaft mounting bolt section, it could deteriorate the
bolt tightening force, and eventually result in deterioration of the transmission torque.
Step 6
Align the mounting holes of the shaft installation component with the positions of the tapped holes
of the reduction gear (shaft section), and then attach the shaft mounting component to the reduction
gear.
• When an O-ring is used, take extra care so that the O-ring is not caught by the mounting surface.
• Confirm that the centering location of the reduction gear (shaft section) is correctly fitted into the
centering location of the shaft mounting flange.
• Check that there is no foreign matter adhering to the mounting surface.
