Carbon powder in motor

Fish out of water · 08-17-2008, 07:59 AM

2000 CC I pulled the motor to put a rubber bushing in to quiet the motor. I found a fine black dust (1/2 a handful) inside housing. Is this common with electric motors?
Thanks Matt

Matt, that is your worn brush material. It's normal but, you are describing a lot of it. Check the length of your brushes. Not certain but I think the book calls for replacement at under 5/8ths of an inch? Anyone confirm or disspell this?

Brush dust is normal.

You should see the amount of dust out of a 100hp 8 brush motor.
