4.4.2. Exchanging of lubrication oil
Engine oil and the oil filter is important factors affecting engine life. They affect ease of starting, fuel econ-
omy, combustion chamber deposits and engine wear. Change the engine oil at 50 hours of operation at first
and next exchange will be performed every 250 hours. At the end of the break in period (50 hours), change
the sump oil and replace the oil filter cartridge to new one.
1) Oil drainage
●
While the oil is still hot, discharge the
sump oil or marine gear sump oil by
motion oil drain pump lever manually as
figure.
●
Refill new engine oil to the filler neck on
the head cover in accordance with the oil
capacity of the engine.
●
Be careful about the mixing of dust or
contaminator during the supplement of
oil. Then confirm whether the oil level
gauge indicates the vicinity of its maxi-
mum level.
●
For a few minutes, operate the engine at
idling in order to circulate oil through
lubrication system.
●
Thereafter shut down the engine. After
waiting for about 10 minutes measure
the quantity of oil and refill the additional
oil if necessary.
Recommend of lubricating oil
Initial factory fill is high quality break-in oil for API Service CI-4 grade. During the break-in period,
frequently check the oil level. Somewhat higher oil consumption is normal until piston rings are seated.
The oil level should be maintained in the safe range between the Min. and Max. mark on the dipstick.
To obtain the best engine performance and engine life, Engine oil is specified by API service, lettered
designations and SAE viscosity numbers. If the specified engine oil is not available, use a reputable
brand of engine oil labeled for API Service CH or CI and SAE viscosity 10W40. Refer to oil
identification symbol on the container.
