ZYAMY 4PCS Electric Spare Part Motor Carbon Brush CB50 CB51 CB60 Carbon Brush Compatible with Makita N1900B 3702B 6010BVR 6400NB 9503BH 5x8x12mm

Specification: Product: Motor Carbon Brush If the motor does not run at full load or does not run at all, it is time to replace the brush. When the brush rubs with the motor armature, small sparks are normal, but too many sparks may mean that a new brush is needed. If a new carbon brush is replaced, and it does not take a few minutes or hours to find that the carbon brush has been worn or half-worn, it means that your rotor has caught fire. Please replace the rotor in time. If you do not replace the rotor, it is useless to replace any more carbon brushes (if the rotor catches fire, it means that the carbon brush is already burning). Application range: 1900B, 19231923B, 3700B, 37023702B, 4014B, 4300A, 4300BA, 4300BV, 4300V, 4401601360166020, 6400NB, 8419B, 9030, JR3000, N1900B, N1923B, N3701, N3702, N4401.
