BRUSH - MOTOR SINGLE (Komatsu KO1-81116-042-0)

A worn motor brush can cause intermittent electrical contact and eventual motor failure. This aftermarket replacement part references the Komatsu catalog number KO1-81116-042-0. The brush is a single motor brush, a consumable component that conducts current between stationary and rotating parts. Over time, brush wear reduces spring pressure, leading to arcing and sparking. In a typical usage context, a brush that is too short may fail to maintain contact, resulting in a no-start condition. The item ships at approximately 0.05 POUNDS. Verify the serial number or application, then call (562) 693-7748.
