BRUSH - MOTOR (Komatsu KO3BB-17-A3241)

KO3BB-17-A3241: A worn motor brush can cause intermittent power loss or arcing inside the motor housing. This aftermarket replacement part references the Komatsu catalog and carries the cross-reference number KO3BB-17-A3241. The brush is a carbon block that slides against the motor commutator to conduct electrical current. Over time, the brush wears down and reduces contact pressure, leading to sparking or motor failure. Keeping the brush at adequate length helps maintain consistent electrical transfer during operation. This item ships at approximately 0.816 pounds.
