Integrated Drive Generator (IDG) Servicing - Filling of the IDG with Oil or Addition of Oil after a Level Check

TASK 12-13-24-612-011-A
Integrated Drive Generator (IDG) Servicing - Filling of the IDG with Oil or Addition of Oil after a Level Check

WARNING: BE CAREFUL WHEN YOU DO WORK ON THE ENGINE PARTS AFTER THE ENGINE SHUTDOWN. USE APPLICABLE THERMAL GLOVES. THE ENGINE PARTS CAN STAY HOT FOR ONE HOUR AFTER SHUTDOWN AND CAN BURN YOU.

WARNING: WEAR GOGGLES, INSULATED GLOVES AND OTHER PROTECTIVE CLOTHES. HOT OIL CAN BURN YOUR EYES AND SKIN. IF OIL TOUCHES YOUR EYES OR SKIN, GET MEDICAL AID.

WARNING: BE CAREFUL WHEN YOU USE CONSUMABLE MATERIALS. OBEY THE MATERIAL MANUFACTURER'S INSTRUCTIONS AND YOUR LOCAL REGULATIONS.

CAUTION: DO NOT OPERATE THE IDG:

IF IT CONTAINS TOO MUCH OIL
IF IT DOES NOT CONTAIN ENOUGH OIL

IF YOU DO, YOU CAN CAUSE DAMAGE TO THE IDG.

CAUTION: USE ONLY NEW CANS OF OIL WHEN YOU FILL THE IDG WITH OIL OR ADD OIL TO THE IDG. THE CONTAMINATION IN OIL THAT STAYS IN OPEN CANS CAN CAUSE FAST DETERIORATION OF THE OIL AND WILL DECREASE THE LIFE OF THE IDG.

CAUTION: REMOVE THE REMAINING OIL FROM THE FILLING EQUIPMENT. FILL THE EQUIPMENT ONLY WITH NEW CANS OF OIL BEFORE YOU FILL THE IDG WITH OIL OR ADD OIL TO THE IDG. THE CONTAMINATION IN THE OIL THAT STAYS IN THE FILLING EQUIPMENT CAN CAUSE FAST DETERIORATION OF THE OIL AND WILL DECREASE THE LIFE OF THE IDG.

CAUTION: DO NOT USE SOLVENTS THAT CONTAIN CHLORINE TO CLEAN THE EQUIPMENT (PUMP, HOSES, TANK AND FUNNEL) USED TO FILL THE IDG WITH OIL. CHLORINE CONTAMINATION OF THE OIL CAN CAUSE FAST DETERIORATION OF THE OIL AND WILL DECREASE THE LIFE OF THE IDG.

CAUTION: DO NOT DO THE SERVICING OF A DISCONNECTED IDG. CONTINUED OPERATION OF A DEFECTIVE IDG CAN CAUSE DAMAGE.

CAUTION: DO NOT LET ENGINE OIL FALL ON THE ENGINE. UNWANTED OIL MUST BE REMOVED IMMEDIATELY WITH A CLEAN LINT FREE CLOTH THE OIL CAN CAUSE DAMAGE TO THE SURFACE PROTECTION AND TO SOME PARTS.

CAUTION: MAKE SURE THAT YOU DO NOT USE TOOLS THAT LET AIR GO INTO THE SYSTEM DURING SERVICING. IF AIR GETS INTO THE SYSTEM, DAMAGE TO THE EQUIPMENT CAN OCCUR.

NOTE: Airbus recommends that you do not do the servicing of more than one IDG at a time.

4. Procedure
Subtask 12-13-24-864-058-B ** ON A/C NOT FOR ALL

A. Depressurization of the IDG Case

WARNING: POINT THE OVERFLOW DRAIN HOSE INTO A CONTAINER WHEN YOU CONNECT THE HOSE TO THE OVERFLOW DRAIN HALF-COUPLING. THIS WILL PREVENT BURNS FROM THE HOT OIL SPRAY. HOT OIL CAN CAUSE BURNS TO EYES AND SKIN.

CAUTION: DO NOT USE DEVICES OTHER THAN THE APPROVED OVERFLOW DRAIN-HOSE FITTING. HARD METAL OBJECTS SUCH AS SCREWDRIVERS CAN CAUSE DAMAGE TO THE OVERFLOW DRAIN HALF-COUPLING SEAT.

(1) Put the CONTAINER 10 L(2 1/2 USGAL) below the IDG (1).
(2) Remove the dust cap (6) from the overflow drain half-coupling (7).
(3) Put the end of the overflow drain hose (5) of the FILLING EQUIPMENT - TANK OIL in the CONTAINER 10 L(2 1/2 USGAL).
(4) Do this step to depressurize the IDG case:
(a) Connect the overflow drain hose (5) of the FILLING EQUIPMENT - TANK OIL to the overflow drain half-coupling (7).

NOTE: Some oil can come out of the overflow drain hose (5) of the FILLING EQUIPMENT - TANK OIL when you connect it.

B. Check of the IDG Oil Brand on the Placard

CAUTION: USE ONLY APPROVED TYPES/BRANDS OF LUBRICANTS. DO NOT MIX TYPES//BRANDS OF LUBRICANTS.

(1) Do a check of the IDG oil brand on the placard:
(a) If the IDG does not have a placard, install the applicable IDG oil-brand placard AIPC 11-24-79-.
(b) If you do not use the same oil brand that is given on the placard, do this procedure (Ref. AMM TASK 24-21-00-612-047).
(c) If you use the same oil brand that is given on the placard, continue this procedure.

Subtask 12-13-24-612-059-B ** ON A/C NOT FOR ALL

CAUTION: USE ONLY APPROVED TYPES/BRANDS OF LUBRICANTS. DO NOT MIX TYPES//BRANDS OF LUBRICANTS.

CAUTION: THE OIL OVERFLOW DRAINAGE PROCEDURE CAN TAKE UP TO 20 MINUTES TO COMPLETE. FAILURE TO OBSERVE THE OVERFLOW TIME REQUIREMENTS CAN CAUSE HIGH IDG OIL LEVEL CONDITION RESULTING IN ELEVATED OPERATING TEMPERATURES AND DAMAGE TO THE IDG.

C. Filling of the IDG with Oil

NOTE: In rain, fog or wet conditions, it is important to prevent water contamination of the IDG oil during the filling procedure.

(1) Remove the dust cap (3) from the pressure fill half-coupling (2).
(2) Connect the pressure fill hose (4) of the FILLING EQUIPMENT - TANK OIL to the pressure fill half-coupling (2).
(3) Fill the IDG (1) with filtered Synthetic base Lubricating Oil-Turbine Engine - - (Material No.03ABA1) at a maximum pressure of 35 psi (2.4132 bar).

NOTE: AMM 20-34-00 gives a list of approved oil brand-names for the IDG servicing.

(4) Stop the filling procedure when the minimum quantity of oil collected from the overflow drain hose (5) of the FILLING EQUIPMENT - TANK OIL is 0.95 l (0.2510 USgal).

Subtask 12-13-24-080-058-B ** ON A/C NOT FOR ALL

D. Removal of the Hoses
(1) Disconnect the pressure fill hose (4) of the FILLING EQUIPMENT - TANK OIL from the pressure fill half-coupling (2).
(2) Install the dust cap (3) on the pressure fill half-coupling (2).
(3) Wait for the flow of oil from the overflow drain hose (5) to decrease to drops.
(4) Disconnect the overflow drain hose (5) of the FILLING EQUIPMENT - TANK OIL from the overflow drain half-coupling (7).
(5) Install the dust cap (6) on the overflow drain half-coupling (7).

Subtask 12-13-24-710-053-A ** ON A/C NOT FOR ALL

E. If you replaced a part of the oil system (filter, external system component or drain plug), do the tests that follow for leak check before inspection:

An idle power test (recommended procedure) (Ref. AMM TASK 71-00-00-710-012) or
A dry motoring (alternative procedure) (Ref. AMM TASK 71-00-00-710-045).

Subtask 12-13-24-210-054-A ** ON A/C NOT FOR ALL

F. Inspection of the IDG Oil Level
(1) To fill the external oil system to its maximum level before the oil level check, it is necessary to:
(a) Do an idle power test (recommended procedure) (Ref. AMM TASK 71-00-00-710-012) or
(b) Do the dry motoring of the engine (alternative procedure) for two minutes (Ref. AMM TASK 71-00-00-710-045). This step is not necessary if it was done in step 4.E.

NOTE: The IDG oil temperature is shown on the ECAM "ELEC SD" page. If the oil temperature is less than 49 DEG.C (120 DEG.F), the oil is cold. If the oil temperature is equal to or more than 49 DEG.C (120 DEG.F), the oil is hot.

(2) Inspection of the IDG oil level after an engine run (recommended procedure) or a dry motoring of the engine (alternative procedure).

CAUTION: IF YOU DRY MOTORED THE ENGINE OR DID AN IDLE POWER TEST, MAKE SURE THAT THE OIL LEVEL IS STABLE BEFORE YOU DO THE INSPECTION. THE OIL LEVEL BECOMES STABLE ONLY AFTER A PERIOD OF: - 30 MINUTES IF YOU DRY-MOTORED THE ENGINE, OR - 5 MINUTES IF YOU DID AN IDLE POWER TEST. THUS, THE LEVEL INDICATIONS ON THE SIGHTGLASS ARE NOT CORRECT BEFORE THE END OF THIS PERIOD. IF YOU ADD OIL WHEN IT IS NOT NECESSARY, FAILURE OF THE IDG CAN OCCUR.

(a)

IDG - Servicing ** ON A/C NOT FOR ALL

(b) If the oil level is not correct, do steps 4.A thru 4.D again.

NOTE: After the oil level correction, no more dry motoring of the engine or the idle power test is necessary.

NOTE: We recommend that you do the visual inspection again to make sure that there are no oil leaks at the cover of the IDG oil filter. You can do this inspection the next time that you operate the engine at a minimum idle.
