I have been told they are a bear to rebuild if you don't get the vanes back to where they did not come from.

It they are a bear to rebuild and a possible cluster ****, then I will take it to my mechanic who knows MB's and has done some work for me before. I have no special tools to boot. I think you need a special tool just to get the pulley off.

Just curiuos if you all have done this and how hard it can be or should I just pay somebody to do it, if I take it to him.

Any feedback would be appreciated.

Thanks!
