3.3) Purging the lubrication system
Safety See Fig. 12.
Introduction Ensure that oil lines are connected correctly and secured and that the oil
cooler (if fitted) is in the suction line (1) between the oil tank and the oil
pump. Verify that the oil tank is filled up to the maximum level (to the top
of the flat portion of the dipstick). Additional oil (up to 0.5 litre
(0.13 USgal)) may be added to the tank for the purpose of this procedure.
Instruction The following work procedures must be carried out:
Risk of burns and scalds.
Hot engine parts.
Always allow engine to cool down to ambient temper-
ature before starting work..
Incorrectly connected oil lines to the oil tank or to the
engine will result in severe engine damage.
Step Procedure
1 Disconnect oil return line (2) from the oil tank.
2 Place the free end (3) of the return line into a suitable container (4) below
the engine.
3 Plug open connection (5) on oil tank with suitable air tight cap.
4 Remove the spark plug connectors.
5 For easier rotation of engine remove one spark plug from each cylinder.
Prevent any foreign objects entering through spark
plug hole.
6 Using a compressed air line, pressurise the oil tank through its purging
connection (6) (on the neck of the tank). Adjust the compressor outlet reg-
ulator so that the air line pressure is between 0.4 bar (5.8 psi) and 1 bar
(14.5 psi). Do not exceed 1 bar (14.5 psi).
Non-compliance can result in serious injuries or
death!
Do not remove the oil tank cover before ensuring that
air pressure has been completely released from the
tank.
