One New Aftermarket Replacement Brush A for Caterpillar (Cat) Equipment
This aftermarket Brush A (OEM part number 2N-6399) is an electrical brush used in motors, alternators, generators, and starter systems on Caterpillar (Cat) construction and industrial equipment. Electrical brushes conduct current between stationary wiring and rotating components such as armatures and slip rings, maintaining reliable electrical contact for consistent motor and generator performance. Replacing worn brushes before they cause sparking or intermittent operation helps extend the life of the surrounding electrical assembly.
