Alternator drive pulley whine

[oddshapedballs]

I get a whine from the alternator drive pulley on tick-over, don't notice it at any other time, it whines with and without the alternator belt on.

Is this normal???

Bike's a 2007 1200gs - belt was replaced last year, 10,000 miles early as I thought the belt was slipping.

Cheers.

How can it whine without the belt on????? it aint moving or doing anything without the belt on. I think you need to look else where then stop worrying and just ride the thing. Or flog it quick I have £100 cash waiting.

The alternator's not whining, the drive pulley (the large one at the bottom that drives the belt that drives the alternator) is whining.

Same question - how can an empty pulley make any noise? Look elsewhere.

If you are convinced it's the pulley wrap some card & gaffer tape around it to absorb ringing noise. 100 to 1 it won't do anything.

The engine cover behind the belt carries stuff that may be making noise.

Perhaps the replacement belt was too tight and you've fecked the drive pulley bearings ?

Just a thought.....to cheer you up.
