I'm in the process of changing the pulley bearing on my '95 E420 air pump. Anyone done this lately and available to offer any tips?
I'm planning to grind away the small, displaced metal tabs at the back of the pulley, press the bearing out and replace it.
Also, I discovered that the box on the back of the pump contains a filter! I had no idea. I cannot find a part number for this filter. Anyone know it?
