Action
Fit the sealing ring and the joint.
Apply grease to the screw thread and between
the washer and the screw head.
Secure with the lubricated screws and washers
and tighten, using the torque wrench head with a
closed end.
Tip
The shaft rotates when loosening/fastening the

ing/tightening the screws. Requires two
persons.

2 Hold the motor shaft still by inserting a pin
through the joints (5-axis robot) or through
the joint and against the casting. Choose
an appropriate material for the pin, that
does not damage the surface of the joints.

handled with care.
