1. Place the speed-sensor rotor on the conical shaft journal and tighten it to a torque of 10
Nm using one M6 screw.
2. Test the rotor to see if it is running smoothly. The permissible rotor deviation on the
commutator is 0.05 mm.
3. Mount the speed-sensor stator. Ensure that the brushes still have sufficient length and do
not become damaged.
