I have a 1986 300E which is shaving off aluminum pieces from the fan clutch. I believe I need to replace the clutch. Can the clutch be removed without special tools? Is it a difficult repair without a proper tool and can the average sidewalk mechanic replace it? Also I looked up the part and it calls for replacing the fan based upon engine #. Does anyone know why the fan needs to be replaced?

Please respond with any advice, it would be greatly appreciated.

Thanks,

Dean
