SPRING - BRUSH (Komatsu KO3KA-17-13280)

KO3KA-17-13280: A worn brush spring can cause intermittent electrical contact, leading to erratic motor performance or unexpected shutdowns. The Komatsu catalog reference for this aftermarket replacement part is KO3KA-17-13280. This spring applies mechanical force to hold a carbon brush against a commutator surface. If the spring loses tension, the brush may bounce or fail to maintain consistent contact. That condition can produce arcing, accelerated brush wear, or reduced power output. The item ships at approximately 0.02 pounds. Verify the serial number or application, then call (562) 693-7748.
