 When sealing with an O-ring

Fit an O-ring (I) into the groove on the
shaft mounting surface.
(Reference: “4.2.6 O-rings”)
 When sealing with a liquid sealant

When sealing the section with a liquid sealant,
coat the liquid sealant onto the
area on
the shaft mounting surface. For the coating area,
refer to the illustration on the right.

Apply coating seamlessly in the coating area.

Take extra care so that the liquid sealant will
not leak into the reduction gear.

Take extra care so that the liquid sealant will
not leak into the shaft mounting bolt section.

For the detailed coating procedure, follow the
instructions given by the manufacturer of the
sealant to be used.
(Reference: “4.2.5 Liquid sealant”)

If a coating is not applied at some points within the coating range, it could cause leakage of the
lubricant.

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.

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.
