A. If the test gives the maintenance message IDG2 HIGH DELTA TEMP:
. If the filter element is bypassed (metal particles on the filter element) or,
. If you think it was bypassed (filter not installed correctly, or filter O-ring damaged, or you are not sure that the filter element was bypassed) or,
. If you smell a fuel odour from the filter element or the filter cover:
Subtask 24-20-00-710-089-A ** ON A/C NOT FOR ALL - do a check of the Differential Pressure Indicator (DPI) of the IDG2 AMM 24-21-00-210-046.
- do the alternate procedure (Ref. TSM TASK 24-21-00-810-816).
- do an inspection of the IDG2 filter element for metallic contamination AMM 24-21-00-210-044.
. If the filter element is bypassed (metal particles on the filter element) or,
. If you think it was bypassed (filter not installed correctly, or filter O-ring damaged, or you are not sure that the filter element was bypassed) or,
. If you smell a fuel odour from the filter element or the filter cover:
- replace the IDG2 oil cooler AMM 73-11-60-000-001 and AMM 73-11-60-400-001.
- clean the tubings of the external system in the overhaul facility:
. remove the tubings AMM 24-21-49-000-040, clean them, and install them AMM 24-21-49-400-040.
- drain the oil AMM 12-13-24-680-040,
- replace the IDG2 oil filter AMM 24-21-51-000-041 and AMM 24-21-51-400-041,
- fill the IDG2 with oil AMM 12-13-24-612-041,
- do a run up,
- drain again,
- replace the IDG2 oil filter again,
- fill the IDG2 with oil again.
- replace the IDG [4000XU] AMM 24-21-51-000-040 and AMM 24-21-51-400-040.
B. After the subsequent flight make sure that the fault does not continue.
