Here is a pic of my Supercharger idler pully and belt
Looks like it is wearing the belt.
Anybody familiar with this ?
Is this type wear normal ? 25K miles

My next service is in a couple weeks and just
a little concerned.

Thanks

That's the undriven side of the belt. You still have the makers white lettering showing so I doubt if there is any wear going on on that side. Wear would be on the ribbed side of the belt and I can't see any wear from the pic. Looks OK to me.

Your right on. Outside is not getting the load.


Called my SA anyway. He said as long as the belt felt smooth
things were OK. He also mentioned that the belt should be replaced about every 10K Miles. So will get it checked next service in a few weeks.
Just dont remember seeing all that wear on that adjust pully face ?

That is normal for all 55 kompressor engines.

I would change it as a maintenance item around 50K miles.
