Not sure if this is the correct way to raise this concern. During LH (left hand) IDG (integrated Drive Generator) filter replacement; found filter bowl with four notches. Inspection revealed that the filter removed has 4 'tabs.' These tabs produced the notches in the bowl. There are several filter P/N (part Numbers) that can be used in IDG. This one P/N is 7583142. Possibly vibrations produced fretting between the tabs and the bowl.Suggestions: Eliminate these filters as alternate part number and use filter that do not have these tabs.
Maintenance Technician reported that an Integrated Drive Generator (IDG) filter that has'4 tabs' is causing damage; 'notches;' to the filter bowl.
