A. Removal of the IDG Oil Filter Elements
(1) Remove the IDG oil charge and scavenge filter elements (Ref. AMM TASK 24-21-51-000-810).
Subtask 24-21-00-210-114-A (1) Remove the IDG oil charge and scavenge filter elements (Ref. AMM TASK 24-21-51-000-810).
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 24-21-00-612-807).
(3) If you think that the condition of the oil in the filter element or on the filter cover is not correct, do the 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 of bright metal particles or larger, non-metallic, black colored, fiber-like pieces:
(5) If there are bright metal particles on the filter element, and:
(a) The filter element and/or the O-ring(s) is (are) damaged (there is a risk of particles in the external circuit):
1 Discard the damaged filter element or/and the O-rings.
2 Remove the IDG oil cooler tubes and hoses (Ref. AMM TASK 24-21-49-000-803) and clean them.
3 Remove the IDG oil cooler (Ref. AMM TASK 73-11-50-000-802) and send it back to the overhaul.
4 Remove the IDG (Ref. AMM TASK 24-21-51-000-806) and send it back to the overhaul facility.
5 Install a new IDG (Ref. AMM TASK 24-21-51-400-806).
6 Install a new IDG oil cooler (Ref. AMM TASK 73-11-50-400-802).
7 Install the IDG oil cooler tubes and hoses (Ref. AMM TASK 24-21-49-400-803) that you cleaned.
(b) The filter element and the O-rings are not damaged, and:
2 Remove the IDG (Ref. AMM TASK 24-21-51-000-806).
3 Send the IDG and the filter element back to the overhaul facility.
4 Install a new IDG (Ref. AMM TASK 24-21-51-400-806).
Subtask 24-21-00-420-097-A NOTE: This procedure is the same for the two filter elements.
(1) Use an LIGHT SOURCE - INSPECTION to do a visual inspection of the filter cavity. (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 24-21-00-612-807).
(3) If you think that the condition of the oil in the filter element or on the filter cover is not correct, do the 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 of bright metal particles or larger, non-metallic, black colored, fiber-like pieces:
NOTE: Small metal flakes (bronze or silver color metal) or non-metal material (for examples flakes of generator insulation, black epoxy, shreds of tie wrap) are the normal result of operation. It is not necessary to remove the IDG.
- Do a visual check of the oil-filter Differential-Pressure Indicator (DPI) (Ref. AMM TASK 24-21-00-210-808):
- Use an LIGHT SOURCE - INSPECTION and an MIRROR - INSPECTION, if necessary.
- Install the filter element you removed (Ref. AMM TASK 24-21-51-400-810).
(5) If there are bright metal particles on the filter element, and:
(a) The filter element and/or the O-ring(s) is (are) damaged (there is a risk of particles in the external circuit):
1 Discard the damaged filter element or/and the O-rings.
2 Remove the IDG oil cooler tubes and hoses (Ref. AMM TASK 24-21-49-000-803) and clean them.
3 Remove the IDG oil cooler (Ref. AMM TASK 73-11-50-000-802) and send it back to the overhaul.

7 Install the IDG oil cooler tubes and hoses (Ref. AMM TASK 24-21-49-400-803) that you cleaned.
(b) The filter element and the O-rings are not damaged, and:
- There are bright metal particles or pieces that are the result of a breakage (other than non-magnetic flakes or slivers from normal wear), or
- There are large quantities of bright metal particules, or non-metal, black colored, fiber-like pieces, in the filter cavity or in the oil drained from the IDG:
2 Remove the IDG (Ref. AMM TASK 24-21-51-000-806).
3 Send the IDG and the filter element back to the overhaul facility.
4 Install a new IDG (Ref. AMM TASK 24-21-51-400-806).
