Installation
I
Before fitting the oil pump to the crankcase ensure
I
I
the pump internal surfaces have been 'wetted' with
I
dean engine oil. The pump-may fail to pickup oil-
from the sump if the surfaces have not been
'wetted'. This will cause the engine to run without
engine oil pressure and will lead to severe engine
damage.
1.
Fill the oil pump with new engine oil, turning the
pump rotor as the
oil is poured in to ensure all
surfaces are coated with oil.
2. Position the oil pump to the crankcase and insert
into the opening provided.
Note:
Use the sprocket end of the oil pump shaft
to turn the drive peg into alignment with
the drive on the water pump.
