This genuine OEM sourced replacement part which is specially designed for use with Milwaukee abrasive cut-off machines. The armature is the central component of an electric motor. It is composed of a steel shaft, copper windings, and a series of commutator bars (through which the carbon brushes transfer electricity). If the tool is overloaded, the copper windings can become extremely hot. If this occurs repeatedly, the insulation surrounding the windings can melt and the armature will fail. It is highly recommended to replace both carbon brushes when replacing an armature. Make sure to refer to the appropriate diagrams for your model to ensure the proper repair procedure.
After disconnecting power, remove blade guard, then remove motor cover, handle cover, trigger cover, disconnect motor supply wires cord from trigger, ( not the power cord!) now remove bottom trigger cover and power cord all as one! remove brushes from brush holder! (checking that every thing looks good!) now remove 4 screws holding motor
