BRUSH - MOTOR (Komatsu KO300315-000)

KO300315-000: A worn motor brush can cause intermittent electrical contact and eventual motor failure. This aftermarket replacement part references the Komatsu catalog and cross-references part number KO300315-000. The brush is a carbon block that conducts current between stationary and rotating motor components. Over time, brush wear reduces spring pressure, leading to arcing and commutator damage. In a typical usage context, a brush that is too short may fail to maintain contact under load. The item ships at approximately 0.104 pounds.
