I have noticed a black dust on my cloth gap seal around where it kind of blows up and touches the electric starter.  I have also noticed the same black dust in my cage.



Anyone ever experience a black dust blowing out of their starter?  Is there any maintenance needed on a starter...such as taking it apart and cleaning it?  I will give Ronnie a call this week and ask him, but wondered if anyone else has seen this?

Back when I had the 532 on the MKIII, the rubber mounting bushings that support the starter seemed to have partially compressed, and the starter case was chafing on the crankcase, creating black dust. If I remember right (?) I shimmed it out a bit and it fixed it.

No I haven't seen it. Guess it depends if the black is coming from inside or

outside the starter.  It may be an indication that the lubricant in the

starter has dried up.   And you are starting to rub metal to metal.   I

would think that removal and lubricating would be in order.  Or the mounting

hardware is chafing.

Ask Ronnie if it could be coming from a loose fan belt wearing out.

You may need to replace the brushes in your starter as they wear down over time from rubbing on the commutator leaving a fine black dust.
