Engine Oil System Filling / Replenishing
Do not mix different brands or types of oil since their different
chemical structures may make them incompatible. If different
brands or types of oil become mixed, drain system (including
engine integral oil tank, engine oil filter housing, engine oil heat
exchanger and oil in and out hoses) and refill with new oil.
NOTE
:
To reduce the possibility of over filling the oil tank, check the oil level 10 minutes
after engine shutdown.
Open oil dipstick hand hold/door (Ref. Figure 8-6 and Figure 8-7).
Remove engine oil filler cap.
Refill engine oil tank with specified oil in related manufacturers' publications
(Ref. RMM, Section 01-00-00)
NOTE
:
Correct oil level is when the observed level is between the MAX and MIN marks
on the oil dipstick. Filling the oil tank to MAX may result in oil being vented
overboard, causing a buildup of carbon deposits on the tailboom and
empennage. Should this occur, monitor engine oil level without adding oil (unless
the oil level falls below MIN) to determine if the level stabilizes at some point
between MAX and MIN. Once this level is determined, fill oil to and maintain this
level.
Replace oil filler cap.
Install and lock the oil filler cap on the oil transfer tube as follows (Ref.
Figure 8-19).
Make sure to install the oil filler cap correctly. Incorrect installation
can lead to disengagement of the cap locking lugs; the cap can
then lift from its locking position and have an incorrect sealing.
This can result in an oil loss that may require shuting down the
engine.
Place the dipstick in the gearbox and make sure that the dipstick off-set
of the cap is in line with the off-set hole of the oil filler tube of the gearbox.
Turn the handle and lock the cap. Make sure that the cap handle is in the
lock position.
If extra force is required to lock the cap, it means that the cap
is not installed correctly. Remove the cap and reinstall it.
NOTE
:
The writing on the cap handle should be facing toward the
front of the engine.
Close oil dipstick hand hold/door.
