Inspecting Engine Oil Systems - TOHATSU TLDI 40 Service Manual

2. Inspecting Engine Oil System
Bleeding Air From Oil Pump
Conduct a visual check of the clear vinyl pipes
connecting the oil pump to the oil tank to inspect for
the presence of air. Bleed hoses if necessary.
Do this by loosening the oil drain screw q on the
air pump and bleed until all air has been removed
from the piping.
Use a cloth to wipe away the bled oil.
Note that the air may not bleed out properly if the
oil in the tank is too low. Make sure to fill the tank
prior to bleeding air from the piping.
Oil Filter and Oil Tank
Check the oil filter for water and foreign matter.
If present, disconnect all piping connecting the oil tank
to the oil pump from the outboard engine and remove
all oil and any water or foreign matter.
Reconnect oil tank and add new oil; then repeat the
same air bleeding procedure used on the oil pump.
