Technical Drive belt and Alternator pulley

[AnthonyH]

Well you can't change an alternator pulley, the're connected to the alternator and come as one whole unit (unless i'm corrected by someone else). The noise is likely coming from the crankshaft pulley. I think you said somewhere above you had a new water pump? If so it'll be a consequence of that job.

The sound in this video is not that of a failing clutch in a pulley (cos you don't have one). But does sound like the of a whining bearing in the alternator itself...

So need a new whole alternator? This is covered under warranty with the used car I got I believe.

Didn't sound particularly whiney to me, but that may be the audio, and it could get worse, OP says the alternator has been tested and is good though?

I'd expect them to say 'its wear and tear' and so not cover it... but no harm in trying

Good at generating power... but can do that with a groaning bearing.

It seems you're probably going to need a new alternator at some point in the future.

Ok no worries thank you. My car is currently in the garage getting my airbag fault rectified. This was covered under warranty. And have asked them to look at the alternator too. See what they say.

Makes no difference as the original poster has a sticking Bendix on the starter motor, the alternator is fine


The 1.2 used a dampened auxiliary pulley

I assume there is also a one-way clutch in the alternator otherwise it would get ripped to shreds

There certainly is in the panda 1.2 69hp alternator as in my old car, same engine and gearbox

They do occasionally fail (rare I know of 1) and also takes the auxiliary pulley out to

Maybe the 500 different, I doubt it though
