The axial position of the Wave Generator in the gearbox is critical for the correct operation of the unit. Please check the
correct position of the Wave Generator against the confirmation drawing.
• Push the greased Wave Generator onto the motor shaft according to the assembly dimension given in the confirmation
drawing. If there is no assembly value given, the Wave Generator must be moved until it reaches the shaft collar.
• Insert the plug into the bore of the Wave Generator Hub and tighten with the screw. When a clamping element is used,
tighten its screws in five steps to the torque given in the confirmation drawing. Final control of the assembly. Some
types of clamping elements can move axially during tightening. Adjust as appropriate.
