Sampling of the IDG Oil for Analysis

TASK 12-32-24-281-001-A
Sampling of the IDG Oil for Analysis

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.
1. Reason for the Job
To find the cause of the oil contamination (Skydrol, fuel, water, chlorine, oil degradation and other causes).
NOTE: The best location and time to get an oil sample is at the case drain after operation of the engine, when the IDG oil is at the operating temperature (80 deg.C (176 deg.F)).

4. Procedure
Subtask 12-32-24-864-050-A ** 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.
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.
   (1) Put the CONTAINER 10 L(2 1/2 USGAL) (4) below the IDG.
   (2) Remove the overflow drain banking-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).
   (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: Oil can come out of the overflow drain hose (5) of the FILLING EQUIPMENT - TANK OIL when you connect it.
Subtask 12-32-24-281-050-B ** ON A/C NOT FOR ALL
B. Oil Sampling
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) Make sure that the oil is not too hot.
   (2) Cut and discard the lockwire from the case drain plug (2).
   (3) Loosen the case drain plug (2).
   (4) Put the BOTTLE 1L (0,26 USGAL) - TRANSPARENT (3) below the case drain port (1).
   (5) Make sure that the BOTTLE 1L (0,26 USGAL) - TRANSPARENT (3) is cleaned with disinfectant.
   (6) Slowly remove the case drain plug (2) until oil flows out of the case drain port (1).
   (7) Fill the BOTTLE 1L (0,26 USGAL) - TRANSPARENT (3) with approximately 20 ml (0.0053 USgal) of oil.
Subtask 12-32-24-420-050-B ** ON A/C NOT FOR ALL
C. Installation of the Case Drain Plug
   (1) TORQUE the case drain plug (2) to between 75 and 55 lbf.in (0.85 and 0.62 m.daN ) T.
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.
   (2) Safety the case drain plug (2) with the 14QFB1Wire-Locking Dia: 0.8 mm CRES Nickel Alloy -.

D. IDG Oil-Sample Analysis
   (1) Send the oil sample bottle to laboratory immediately with these data:
     (a) Oil sampling date
     (b) Type and brand of oil used
     (c) Operating time since last oil sampling
     (d) IDG total operating-time
     (e) Identification of the IDG (Serial Number).
NOTE: If you do not do the analysis immediately, seal the bottle.
   (2) When you get the results of the IDG oil-sample analysis, compare them with the IDG "Oil Contamination Limits" values (maximum values) given in the Standard Practices Manual (SPM) (V99167) 24-10-00 chapter "TESTING", paragraph "Oil Condition":
     (a) If the results of the IDG oil-sample analysis are less than or equal to the IDG "Oil Contamination Limits" (maximum values):
  • No more maintenance is necessary.
     (b) If one of the results of the IDG oil-sample analysis is more than the IDG "Oil Contamination Limits" (maximum values):
