Clk 270 cdi 2005 reg pulley deflector wheel replacement

[alf1956]

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

Yes, center bolt out and replace. Only real issue is stripping the bolt, so use a well fitting torx

Has anybody got a diagram of how the belt goes round the pulleys as it looks a bit complex.

Will the belt snapping cause any engine damage ? It shredded at tick over speed. Is one of the pulleys that twists to tension the belt ?

My CLK has M272 motor, the set up looks about the same. If the idler and tension pulleys are original change them, they give no warning when they let go. Use only OEM.
