Snap rings
Snap ring installers must be designed so as not to
permanently deform the snap rings (1).
Installed snap rings must be installed correctly in
the groove.
Be careful not to overload the snap ring to the
point that the snap ring is permanently deformed.
Install a snap ring as shown in the figure, with its
round edge turned toward the retained part. This
round edge is formed when the snap ring is
pressed out.

When locking the bolts or nuts with wire, take note in the winding direction to hold the bolt tight.
