Technical AC compressor clutch pulley

[arekp]

I've just posted a DIY on replacing the AC compressor clutch in 500X DIY section.

Does any one know if the contact surface is supposed to be rusty?

Good on you sir. Im sure this is a thing that many may need and when it happens a way of saving money.

My clutch was far rustier than the online videos.

Of course it's not 'supposed to be rusty'.
But... it sometimes happens to be rusty.
