Odd 996 Tip Alternator Pulley Wear

Recommended Posts

I pulled the serpentine belt off my 2004 996 w/ Tip to check for a whirring noise. The tensioner pulley did fell a bit rough and little wobbly.

While the belt was off, I noticed that the alternator pulley was wearing oddly. The grooves were unevenly worn, as if some portions of the groove peaks were missing. Has anyone seen this before?

If the alternator has a freewheel pulley, than he will probably stuck. Replace the pulley if that is the case, special tool is needed.
