6 MAINTENANCE
6.1 Lubrication System
Jabiru 3300 Aircraft Engine
Hydraulic Valve Lifter Models
Oil Change as required, Oil Filter Change as required, Visual Check for Leaks.
Drain the oil while engine is still warm.
Change the oil filter at 50 hour inspection.
Fill with oil. Capacity is 3.5 litres (3.69 US Quarts), check oil level with dipstick screwed right in
before removing to check.
Check oil level. The MAX mark must not be exceeded.
Use only registered brand oils meeting the specification detailed in section 3.
6.2 Air Intake Filter
Clean filter by removing from the intake housing & blowing compressed air against the direction
of the intake flow.
For operation in heavy dusty conditions, clean air filter at shorter intervals than recommended
for normal conditions.
A clogged filter will reduce engine performance as well as promote premature engine wear.
6.3 Carburettor Adjustment
Idle stop screw is a 7mm screw against the throttle lever. Adjust it‟s position to adjust engine
idle speed.
Standard idle mixture screw position is approximately 1-1/4 turns out. Fine adjustment may be
necessary to give a smooth idle.
The mixture is set by selecting jet sizes. As supplied, the engine has jets to suit a majority of
installations, however, the mixture may be affected by running a propeller which dose not meet
the requirements listed in the installation manual or by ambient temperature extremes. If an
engine is to be used in these situations an EGT gauge should be fitted and monitored against
the limits specified above.
CAUTION:
Do not change carburetor settings without consulting with Jabiru Aircraft or our local
authorized representative. If EGT readings fall outside the range given above, contact
Jabiru Aircraft or our local authorized representative.
The carburetor automatically adjusts the mixture to account for altitude.
IMPORTANT
Check carburettor joints for degradation.
