Draining of the Oil from the Integrated Drive Generator (IDG)

TASK 12-13-24-680-010-A
Draining of the Oil from the Integrated Drive Generator (IDG)

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

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

4. Procedure
Subtask 12-13-24-864-057-A ** ON A/C NOT FOR ALL

A. Depressurization of the IDG Case
(1) Let the IDG temperature decrease to 120 DEG.F (49 DEG.C) or less before you drain the oil.

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.

CAUTION: MAKE SURE YOU CONNECT THE HOSE OF THE OVERFLOW DRAIN HALF- COUPLING CORRECTLY. THIS HOSE LETS THE OIL IN THE IDG DRAIN TO THE CORRECT LEVEL. IF THERE IS TOO MUCH OIL IN THE IDG THE IDG WILL BECOME TOO HOT.

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

NOTE: Some oil can come out of the overflow drain hose (6) of the FILLING EQUIPMENT - TANK OIL when you connect it.

B. Draining of the IDG Oil

WARNING: USE PROTECTIVE GOGGLES AND GLOVES WHEN YOU REMOVE OR INSTALL LOCKWIRE. EACH TIME YOU CUT LOCKWIRE, REMOVE AND DISCARD IT IMMEDIATELY. LOOSE LOCKWIRE CAN CUT YOU OR MAKE YOU BLIND, AND/OR CAN CAUSE DAMAGE.

(1) Cut and discard the lockwire from the case drain plug (4).

NOTE: Approximately 5.72 l (1.5111 USgal) of oil will flow into the CONTAINER 10 L(2 1/2 USGAL).

(2) Remove the case drain plug (4).
(3) Remove and discard the packing (3).
(4) Drain the oil:

The oil condition is unsatisfactory.

(5) Remove the dust cap (7) from the pressure fill half-coupling (9).
(6) Connect the pressure fill hose (8) of the FILLING EQUIPMENT - TANK OIL to the pressure fill half-coupling (9).
(7) Use the FILLING EQUIPMENT - TANK OIL to fill the IDG (1) with new Synthetic base Lubricating Oil-Turbine Engine - - (Material No.03ABA1) and to drain the used oil:
(a) Make sure that the filling pressure is not more than 2.41 bar (34.95 psi).
(8) Continue to fill the IDG (1) with new Synthetic base Lubricating Oil-Turbine Engine - - (Material No.03ABA1) until a minimum of 1.85 l (0.49 USgal) of oil flows out of the case drain.
(9) Stop the FILLING EQUIPMENT - TANK OIL.
(10) Let the oil drain from the case drain until the flow of oil decreases to drops.
(11) Disconnect the pressure fill hose (8) of the FILLING EQUIPMENT - TANK OIL from the pressure fill half-coupling (9).
(12) Install the dust cap (7) on the pressure fill half-coupling (9).
