SPRING - BRUSH - MOTOR (Komatsu KO300665-001)

KO300665-001: A worn brush spring can cause intermittent motor contact, leading to power loss or arcing. This aftermarket replacement part references Komatsu catalog number KO300665-001. The spring applies consistent pressure to maintain brush-to-commutator contact in a motor assembly. If the spring loses tension, the brush may bounce, resulting in sparking and reduced motor efficiency. In a typical usage context, a failed spring can prevent the motor from starting or cause erratic operation. Verify the serial number or application, then call (562) 693-7748.
