• Take extra care so that the O-ring is not caught by the
mating section.
• Confirm that the centering shaft of the center tube is
correctly fitted into the centering hole of the reduction
gear (shaft section).
• 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 reduction gear may differ from the illustration below depending on the ordered
specifications.
