B. Visual Inspection of the IDG Oil Filter Elements
(2) If you smell fuel from the filter element or the filter cap, do the servicing of the IDG after oil chemical contamination (Ref. AMM TASK 24-21-00-612-804).
(3) If you think that the condition of the oil in the filter element or on the filter cover is not correct, do a sampling of the IDG oil for analysis (Ref. AMM TASK 12-32-24-281-001).
(4) If the filter element, the filter cap and the filter cavity do not show signs bright metal particles or larger, non-metallic, black colored, fiber-like pieces:

- If there are large quantities of bright metal deposits, or non-metallic, black colored, fiber-like pieces, in the filter cavity or in the oil drained from the IDG.
2 Remove the IDG (Ref. AMM TASK 24-21-51-000-803),
