Hello fellow ,members the deflector pulley on my Clk 270 cdi has lost the last 2 V grooves on the belt pulley deflector which has just shredded the belt I am wondering if it is a straight forward swap job? The bearing seems fine with no play so I am planning on just swapping the pulley itself & not the whole assembly
 
I'd be asking myself why the pully lost the grooves. Wobbling? Bearing?
This was the kompressor belt idler/guide pulley from my CLS. Fortunately it didn't throw a belt and it was due to be replaced anyway.
MB's price for a replacement pulley? £465.60!!!!!!!!!!
My local parts factors sourced me an OEM for under £200.

Thank you for the reply, if it had thrown the belt what damage would it have caused ? My belt threw off on tick over outside my house.
