S/C Belt tensioner pulley, bearing nr ?

Hi.

I've heard a noice that have started to come from my S/C belt tensioner bearing. And was wondering if anyone have the bearing number, so that I can get the bearing before I remove the wheel and replace it.

Number 29 in this foto is the tensioner I mean =)



Thanks

I have a new aluminum replacement smooth tensioner idler in stock, if you prefer to go that route? Comes with high quality HD bearings too. Most change all thier idlers at the same time,as they all tend to fail with time.

Pressing a new bearing into a plastic part does not usually work very well. The heat from the old bearing just makes for a bad plastic pulley.

I've thought about replacing it with the aluminium billet. But that's seems expensive compared to just swaping the bearing =)

But my tensioner pulley is not made out of plastic !



This is the wheel I mean. My have some scratches on in, and under the paint it looks like some metall.

But you to not know the bearing nr on it ?
