TASK 12-13-24-680-010-ADraining of the Oil from the IDG

WARNING: BE CAREFUL WHEN YOU WORK ON THE ENGINE COMPONENTS IMMEDIATELY AFTER

THE ENGINE IS SHUTDOWN. THE ENGINE COMPONENTS CAN STAY HOT FOR UP TO ONE

HOUR.

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.

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 DE-

FECTIVE IDG CAN CAUSE DAMAGE.

A. Depressurization of the IDG Case



BURNS FROM THE HOT OIL SPRAY. HOT OIL CAN CAUSE BURNS TO EYES ANDSKIN.




(1) Put a CONTAINER 10 L(2 1/2 USGAL) below the IDG (2).


(3) Put the end of the overflow drain hose (3) of the FILLING EQUIPMENT - TANK OIL, DH13PM TYP inthe CONTAINER 10 L(2 1/2 USGAL).

(4) Do this step to depressurize the IDG case:


14/22






(a) Connect the overflow drain hose (3) of the FILLING EQUIPMENT - TANK OIL, DH13PM TYP tothe overflow drain half-coupling (8).

NOTE: Some oil can come out of the overflow drain hose (3) of the FILLING EQUIPMENT -TANK OIL, DH13PM TYP when you connect it.

Subtask 12-13-24-612-059-A

CAUTION: THE OIL OVERFLOW DRAINAGE PROCEDURE CAN TAKE UP TO 20 MINUTES TO COM-

PLETE. FAILURE TO OBSERVE THE OVERFLOW TIME REQUIREMENTS CAN CAUSE

HIGH IDG OIL LEVEL CONDITION RESULTING IN ELEVATED OPERATING TEMPERAT-

URES AND DAMAGE TO THE IDG.

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

OF LUBRICANTS.

B. Filling of the IDG with Oil

NOTE: In case of OIL type/brand change, refer to (Ref. AMM TASK 24-21-00-612-047) .

NOTE: In rain, fog or wet conditions, be careful to prevent water contamination of the IDG oil during thefilling procedure.

(1) Remove the dust cap (6) from the pressure fill half-coupling (7).

(2) Connect the pressure fill hose (5) of the FILLING EQUIPMENT - TANK OIL, DH13PM TYP to thepressure fill half-coupling (7).

(3) Fill the IDG with the filtered Synthetic base Lubricating Oil-Turbine Engine - - (Material No. 03-ABA1)at a maximum of 35 psi (2.4132 bar).

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

(4) Stop the filling procedure when the quantity of oil collected from the overflow drain hose (3) of theFILLING EQUIPMENT - TANK OIL, DH13PM TYP is 0.95 l (0.2510 USgal) minimum.

Subtask 12-13-24-080-058-A

C. Removal of the Hoses

(1) Disconnect the pressure fill hose (5) of the FILLING EQUIPMENT - TANK OIL, DH13PM TYP fromthe pressure fill half-coupling (7).

(2) Install the dust cap (6) on the pressure fill half-coupling (7).(3) Wait for the flow of oil from the overflow drain hose (3) to decrease and become only drops.

(4) Remove the overflow drain hose (3).


Subtask 12-13-24-710-053-A

D. If you replaced a part of the oil system (filter, external system component, drain plug), do dry motoring forleak check before inspection (Ref. AMM TASK 71-00-00-710-045) .

Subtask 12-13-24-210-054-A

E. Inspection of the Oil Level

NOTE: To fill the external oil system to its maximum level before the oil level check, it is necessary to:- Dry-motor the engine (Ref. AMM TASK 71-00-00-710-045) for two minutes, or to


15/22






- Operate the engine at minimum idle (Ref. AMM TASK 71-00-00-710-043) .

NOTE: The IDG oil temperature is shown on the lower ECAM display unit. When the oil temperature is thesame as the ambient air temperature, the oil is cold. When the oil temperature is more than theambient air temperature, the oil is hot.

(1) Inspection of the oil level with dry motoring

CAUTION: IF YOU DRY-MOTOR THE ENGINE, MAKE SURE THAT THE OIL LEVEL IS STABLE

BEFORE YOU DO THE INSPECTION. THE OIL LEVEL WILL BECOME STABLE

ONLY AFTER 30 MINUTES. THUS THE LEVEL INDICATIONS ON THE SIGHT-

GLASS 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) Wait thirty minutes to let the oil in the IDG become stable.

(b) Look at the oil level sightglass of the IDG:

1 If the oil is cold:If the oil level is only immediately above the lower limit of the yellow band because of theaircraft ramp angle, IDG oil draining is not necessary. If the oil level is in the yellow band, do the steps 4.A. and 4.C. again. If the oil level is below the green band, do the steps 4.A. thru 4.C. again.

2 If the oil is hot:If the oil level is in the yellow band, oil servicing is not necessary. If the oil level is below the green band, do the steps 4.A. thru 4.C. again. If the oil level is above the yellow band, do the steps 4.A. and 4.C. again.

NOTE: After oil level correction, no further dry motoring is necessary.

NOTE: If the oil level is below the middle of the green band, we recommend that you do thetop up.

(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 sightglass of the IDG:

1 If the oil is cold:If the oil level is only immediately above the lower limit of the yellow band because of the

aircraft ramp angle, IDG oil draining is not necessary. If the oil level is in the yellow band, do the steps 4.A. and 4.C. again. If the oil level is below the green band, do the steps 4.A. thru 4.C. again.

2 If the oil is hot:If the oil level is in the yellow band, oil servicing is not necessary. If the oil level is below the green band, do the steps 4.A. thru 4.C. again. If the oil level is above the yellow band, do the steps 4.A. and 4.C. again.

NOTE: After oil level correction, no further dry motoring is necessary.

NOTE: In rain, fog or wet conditions, you must use precautions to prevent water contamination of the IDGoil during filling procedures.

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

(1) Remove the dust cap (5) from the pressure fill half-coupling (6).

(2) Connect the pressure fill hose (4) of the FILLING EQUIPMENT - TANK OIL, DH13PM TYP to thepressure fill half-coupling (6).

(3) Slowly pump the filtered Synthetic base Lubricating Oil-Turbine Engine - - (Material No. 03-ABA1) intothe IDG to 35 psi (2.4132 bar) maximum.

(4) Stop this operation when the oil level in the sightglass (8) is at the top of the green band.

NOTE: There is a delay between the oil complement and the oil level change in the sightglass.

NOTE: Look at the oil level sightglass of the IDG: (Ref. Fig. Quick Oil Servicing - IDG)- the oil level must be at or near the line between the yellow band and the green band,- if the oil level is above this position, do the normal procedure of oil replenishing to adjust the

oil level.
