SPRING BRUSH (Nissan NI29144-30H00)

NI29144-30H00: A worn brush spring can cause intermittent electrical contact, leading to erratic motor performance or unexpected shutdowns. This aftermarket replacement part references Nissan catalog number NI29144-30H00. The spring applies consistent pressure to maintain brush-to-commutator contact in a motor assembly. If the spring loses tension, the brush may bounce or fail to seat, resulting in arcing or reduced power output. In a typical service context, a failed brush spring often produces visible sparking or a burning smell. Verify the serial number or application, then call (562) 693-7748. The part is a retaining ring type component that secures the brush assembly in place.
