LUBRICATION
Engine oil
Engine oil should be MIL-L-2104C or have properties of API classification CC/CD/CE grades. The following table
gives grades of oil required for various ambient temperatures.
AMBIENT TEMP
-30°C TO 0°C
-15°C TO +15°C
0°C TO +30°C
25°C AND ABOVE
Note: A good quality 15W/40 multigrade oil as used in most diesel car engines will meet these requirements.
Do not use 'Turbo Diesel Oil' or additives.
CHECKING ENGINE OIL LEVEL
For quantities of oil required see section marked 'Technical Specification', Page 4
When checking the engine oil level, do so before starting, or more than five
minutes after stopping.
1. To check the oil level, draw out the dipstick, wipe it clean, re-insert it, and draw
it out again. Check to see that the oil level lies between the two notches.
2. If the level is too low, add new oil to the specified level - Do not overfill
IMPORTANT
When using an oil of different make or viscosity from the previous one, drain old
oil. Never mix two different types of oil. Engine oil should be changed after first
50 hours running time and then every year or every 250 hours if sooner. Oil
filter is a cartridge type mounted on the starboard side of the engine.
CHANGING ENGINE OIL
(1) Run the engine for 10 minutes to warm up the oil.
(2) Your engine is provided with a sump drain pump. Unscrew the end cap on the
end of the pump, turn the tap to 'on'. Use the hand pump as shown to pump
out the oil into a bucket. Turn the tap to off position and replace end cap. See
diagram 2c.
(3) Unscrew the oil filter and replace with a new one. See diagram 2d.
Note: It is best to have a plastic bag wrapped round the filter to catch any oil
left in the system. (Always keep your bilges clean!) Before screwing in the new
filter spread a thin film of oil round the rubber gasket to ensure a good seal
and screw in – hand tight.
(4) Fill the engine with new oil as described on the previous page.
(5) Run the engine and check for oil leaks.
