R (Ref. Fig. 304/TASK 12-13-79-991-302)
R Subtask 12-13-79-210-067
R A. Check oil level and master Magnetic Chip Detector (MCD) visual indicator.
R NOTE : In order to reduce burden for nuisance EMCD pop out indication,____
R the inspection of the Electrical Master Chip Detector can be
R defeered to the next convenient maintenance opportunity where
R trained personnel can performed the inspection without interfering
R with revenue service operation.
R (1) Check the visual indicator of the MCD. If the pop-out is extended
R (Ref. TASK 79-00-00-281-002).
R (2) Check oil level on the sight gage, if oil level is below full mark
R add oil as follows:

R Subtask 12-13-79-612-071
R B. Fill the pump:
R (1) Remove blanking caps from couplings.
R (2) Attach hose coupling from oil service system to remote oil filling
R port. Attach plastic transparent overflow hose to oil overflow port.
R CAUTION : DURING FILLING, THE MAXIMUM OIL PUMP FLOW RATE MUST NOT_______
R EXCEED 66 US GAL/HR (250L/HR), OR OVERSERVICING OF OIL
R SYSTEM MAY RESULT.
R CAUTION : REMOVAL OF DRAIN LINE BEFORE FLOW OF OIL FROM OVERFLOW HOSE_______
R STOPS MAY RESULT IN AN OVERSERVICED TANK.
R NOTE : Use of a plastic transparent hose in place of an opaque hose____
R will allow detection of oil at overflow port location (oil
R tank "full") and give visual indication to stop filling
R sooner.
R (a) Add engine oil Ref. SB CFM 79-001 (Material No. CP2442) through
R oil service system until oil is visible through plastic
R transparent hose at the oil overflow port location.
R (3) When oil flow from overflow hose stops, disconnect oil service system
R and check for oil leakage from the coupling. Slightly wetted surface,
R insufficient to form a drop, is permitted.
R (4) Reinstall blanking caps on couplings.
R 5. Close-up________

Oil Tank Draining
WARNING : DO NOT REMOVE THE FILLER CAP OF THE OIL TANK IMMEDIATELY AFTER ENGINE
_______ OPERATION. LET THE OIL PRESSURE DECREASE FOR A MINIMUM OF 5 MINUTES AFTER THE ENGINE SHUTDOWN. IF YOU OPEN THE FILLER CAP WHEN THERE IS PRESSURE IN THE TANK THE OIL CAN BURN YOU DANGEROUSLY.
CAUTION : MAKE SURE THAT THE OIL TANK SCUPPER IS CLEAN TO PREVENT CONTAMINATION
_______ OF THE TANK DURING THE SERVICING OPERATIONS.
