Lubrication
Installation
As
a precaution, before fitting the
oil
pumps to the
crankcase ensure the pump internal surfaces
have
been 'wetted' with clean engine oil. The pumps may
fail to pick-up 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 pumps with new engine oil, turning the
pump rotors as the oil is poured into the pump.
2.
Position the scavenge pump to the crankcase
and engage it to the mounting dowels. Ensure
the drive blade
is
facing towards the front of the
engine.

way.
