BRUSH - MOTOR SET OF 4 (Mitsubishi MB0973034)

A worn motor brush set can cause intermittent power loss or arcing inside the motor housing. This aftermarket replacement part references Mitsubishi as the OE maker and cross-references part number MB0973034. The brush set consists of four carbon blocks that conduct current to the motor's rotating commutator. As the brushes wear down, spring tension decreases, leading to poor electrical contact and reduced motor performance. In a typical usage context, a set of four brushes is replaced together to ensure even wear and consistent current transfer. The item ships at approximately 0.22 pounds. Verify the serial number or application, then call (562) 693-7748.
