E. Inspection of the Oil Level
NOTE : Before you do a check of the oil level, we recommend that you do
____ dry motoring for two minutes (Ref. TASK 71-00-00-710-001). Alternatively, you can do the check after an engine run at minimum idle (Ref. TASK 71-00-00-710-003). This is to make sure you get maximum filling of the external oil circuit.
(1) Inspection of the oil level with or without dry motoring.
CAUTION : IF YOU DRY-MOTOR THE ENGINE, MAKE SURE THAT THE OIL LEVEL
_______ IS STABLE BEFORE YOU DO THE INSPECTION. IN AMBIENT AIR TEMPERATURES OF LESS THAN 20.C, THE OIL LEVEL WILL BECOME STABLE ONLY AFTER 30 MINUTES. THUS THE LEVEL INDICATIONS ON THE SIGHTGLASS WILL NOT BE CORRECT BEFORE THE END OF THIS PERIOD. IF YOU ADD OIL WHEN IT IS NOT NECESSARY, THERE IS A RISK THAT YOU WILL CAUSE FAILURE OF THE IDG.
(a)
Let the oil in the IDG become stable.
(b)
Look at the oil level sightglass of the IDG:
-
if the oil level is at or near the top of the green band, oil servicing is not necessary.
-
if the oil level is below the green band, do the steps 4.A. thru 4.D. again.
-
if the oil level is above the green band, do the steps 4.A. and
4.C. again.
(2) Inspection of the oil level after an engine run (alternative
procedure).
(a)
Let the oil in the IDG become stable for 5 minutes.
(b)
Look at the oil level sight-glass of the IDG:
-
if the oil level is in the green or yellow band, oil servicing is not necessary,
-
if the oil level is below the green band, do the steps 4.A. thru 4.D. again.
-
if the oil level is above the yellow band, do the steps 4.A. and 4.C. again.
