BRUSH - MOTOR SET OF 8 (Komatsu KO4909072)

KO4909072: A worn motor brush set 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 KO4909072. The brush set consists of eight individual carbon brushes that maintain electrical contact between the stationary and rotating parts of a motor. Over time, brush wear reduces contact pressure, leading to sparking and eventual motor failure if not replaced. Keeping a brush set in sound condition helps sustain consistent motor performance and prevents damage to the commutator surface. The item ships at approximately 0.34 POUNDS. Verify the serial number or application, then call (562) 693-7748.
