4. Fault Isolation
_______________
A. If the test gives the maintenance message IDG1 HIGH DELTA TEMP:
- do a check of the Differential Pressure Indicator (DPI) of the IDG1 (Ref. AMM TASK 24-21-00-210-046).
(1) If the DPI is extended:
- replace the IDG (4000XU) (Ref. AMM TASK 24-21-51-000-040) and (Ref. AMM TASK 24-21-51-400-040),
- do an inspection of the IDG1 filter element to make sure that it is not bypassed (Ref. AMM TASK 24-21-00-210-044).
(2) If the DPI is not extended:
- do an inspection of the IDG1 filter element for metallic contamination (Ref. AMM TASK 24-21-00-210-044).
(a) . If the IDG1 filter element is damaged or, . 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 IDG1 oil cooler (Ref. AMM TASK 73-11-60-000-002) and (Ref. AMM TASK 73-11-60-400-002).
- clean the tubings of the external system in the overhaul facility: . remove the tubings (Ref. AMM TASK 24-21-49-000-003) (Ref. AMM TASK 24-21-49-000-004), clean them, and install them (Ref. AMM TASK 24-21-49-400-003) (Ref. AMM TASK 24-21-49-400-004).
(b) If the IDG1 filter is in good condition and oil is abnormally cold:
- drain the oil (Ref. AMM TASK 12-13-24-680-040),
- replace the IDG1 oil filter (Ref. AMM TASK 24-21-51-000-041) and (Ref. AMM TASK 24-21-51-400-041),
- fill the IDG1 with oil (Ref. AMM TASK 12-13-24-612-041),
- do a run up,
- drain again,
- replace the IDG1 oil filter (Ref. AMM TASK 24-21-51-000-041) and (Ref. AMM TASK 24-21-51-400-041),
- fill the IDG1 with oil again (Ref. AMM TASK 12-13-24-612-041).
1 If the fault continues:
_
- replace the IDG (4000XU) (Ref. AMM TASK 24-21-51-000-040) and (Ref. AMM TASK 24-21-51-400-040).
B. After the subsequent flight, make sure that the fault does not continue.
