Jabiru Aircraft Pty LtdInstruction & Maintenance ManualJabiru 2200 Aircraft EngineHydraulic Valve Lifter Models14.1.9 Knocking Under LoadPossible CauseRemedy1) Octane rating of fuel too low Use fuel with higher octane rating2) Spark plug fitted without sealing washer Ensure one sealing washer on each plug3) Heavy carbon deposits Remove cylinder heads & in combustionchamber remove deposits. Determine oilconsumption.Notes:- Running this engine on low octane fuel will cause piston damage and in extreme casesfailure of the top ring gland or holed piston due to detonation.- Changing the engine tuning to a leaner air fuel mix can cause piston damage.14.1.10 Engine Hard to Start at Low TemperaturePossible CauseRemedy1) Starting speed too low Preheat engine2) High oil pressure At very low temperatures, a pressurereading of up to around 500 kpa doesn'tnecessarily indicate a malfunction3) Low battery charge Fit fully charged battery14.1.11 Hydraulic Valve LiftersSymptoms Possible Cause Remedy“Soft” lifter(s) due to lifter fault Replace lifter(s)“Soft” lifter(s) due to low oil See Low Oil Pressure sectionpressureabove.1) Engine noisy, “tapping” at idleRun engine.

Jabiru Aircraft Pty LtdInstruction & Maintenance ManualJabiru 2200 Aircraft EngineHydraulic Valve Lifter Models14.2 Troubleshooting Quick Guide14.2.1 Low Oil PressureA sudden drop of pressure usually is caused by a piece of foreign matter lodging underthe relief valve. Simply remove oil filter and cooler adaptor (if fitted). Remove matter bydepressing plunger or removing relief mechanism. Replace and check operation byground run. If low pressure persists the problem will need further investigation.High oil temperature can cause low oil pressure. Ensure oil temperature remainswithin limits at all times. The fitting of an approved oil cooler is strongly recommended.14.2.2 Flicking Of Oil Pressure GaugeIt is not uncommon for the Jabiru engine to display flicking of the needle pointer forbrief periods but still within normal operating regions. If it continues, check continuity ofsender lead and or possible sender change. (We are assuming oil level is OK).14.2.3 CHTIf the gauge is not reading, the cause can be cause by a break in the sender wires orincorrect polarity.High readings can result from a poorly centred sender under the spark plug.Normal cruise CHT should not exceed 150°C and climb must not exceed 200°C. Airducts supplied at present give results below these figures.14.2.4 RPMTacho’s may need adjustment when a new engine is fitted. Inducted magnet senderunits require coil gap to flywheel tags of .014” or .35mm.14.2.5 Magneto ChecksPossible causes of abnormal drop could be loose leads, faulty leads, rotor buttons, coilgaps, spark plugs.14.2.6 Rough Cylinder RunningCheck plugs, ignition coils and the induction system for looseness.14.2.7 Carby BreatherCarburetors have a brass fitting for venting. This is must be connected to a fittingscrewed into filtered side of the carby heat box14.2.8 LimitationsJabiru recommend TBO of 2000 hrs, with a Top End overhaul at 1000 or when enginecondition indicates the need for overhaul earlier.CAREFULLY READ MANUALS SUPPLIEDThis document is controlled while it remains on the Jabiru server.
