Disconnect the hose from the oil pump inlet, and connect the short hose and ‘T’ piece from the test
kit, with the pressure/vacuum gauge connected to the leg of the ‘T’.
Before first start it is necessary to prime the oil system. There are several methods to achieve this -
the easiest is as follows: -
Disconnect one of the oil cooler hoses at the cooler and fill the cooler utilizing a suitable funnel;
reconnect the hose.
Fill the oil tank with approximately 2 litres of oil.
Disconnect the suction line from the oil tank and fill the oil hose with oil utilizing a suitable funnel.
Ensuring that the ignition is switched off crank the engine by hand a few turns; the oil pump will suck
the oil in.
Reconnect the oil suction line to the tank. Crank the engine with the starter with the ignition
“off”until a steady minimum oil pressure is indicated on the oil pressure gauge.
Start the engine and observe oil pressure - it must rise within 10 seconds to at least 2 bar (30 psi). If
the pressure does not rise, stop the engine straight-away and prime the oil system again.
CAUTION
When conducting any checks do not run the engine at high power settings without having suitably
secured the aircraft against unwanted movement. For monowheel aircraft it is strongly advised to
tie the tailwheel down to prevent the possibility of nosing over.
After priming, make sure that all oil connections are secure and that the oil tank is still full at least to
its mid level.
Although the engine has been run in by the manufacturers, it is prudent to operate it initially at a fairly
conservative power rating until you are sure that there are no problems with cooling.
Once you are happy with the general engine running you can carry out the remaining fuel and oil
system checks.
Oil system check
Run the engine at full power, and check that the depression in the oil inlet pipe as measured by the
gauge already fitted is less than 0.3 bar (4.4 psi). If the depression is greater than this, check the hoses
for kinks or for any other restriction in the system before continuing to operate the engine.
