5.3 Alternator maintenance
procedures
5.3.1 Measuring the alternator
insulation resistance
A 500 V megger is required to measure the alternator
insulation resistance.
If the N-terminal is connected to the earthing system,
it must be disconnected from the earth terminal.
Disconnect the AVR.
Connect the megger between the earth terminal and
terminal L1 and generate a voltage of 500 V. The
scale must indicate a resistance of at least 5 MΩ.
Refer to the alternator operating and maintenance
instructions for more details.
5.4 Engine maintenance
procedures
Refer to the Engine Operation Manual for a full
maintenance schedule.
5.4.1 Engine oil level check
Consult the Engine Operation Manual for the oil
specifications, viscosity recommendations and oil
change intervals. For the intervals, see also section
“Maintenance schedule” on page 46.
– Check the engine oil level by using the oil level
dipstick (OLD).
– Top up with oil (FCO), if necessary.
Refer to the Engine Operation Manual for more
detailed instructions.
5.4.2 Engine oil and oil filter change
Replacing the oil filter element
– Place an appropriate drain pan under the oil drain
flexible.
– Remove the drain plug from the oil drain flexible
to drain the oil.
– Replace the seal of the drain plug.
– Install and thighten the drain plug on the oil drain
flexible.
– Unscrew the oil filter element (OF) from the
adapter head.
