be clearly specified as chunks or pieces caused by breakage, or a large number of small metallic flakes (bronze or
silver-colored metal), replace the IDG. These are indications of IDG internal damage. The filter is breached if the filter
is damaged or missing, the O-ring is damaged or missing, or the filter cap is damaged or loose.
