SYSTEM LIMITATIONS Operating limits Refer to latest issue of the Operators Manual (OM). m WARNING Non-compliance can result in serious injuries or death! The lubrication system must be designed such that the permissible operating tempera- tures and maximum values are not exceeded.
  • Page 188 BRP-Rotax INSTALLATION MANUAL NOTICE Do not remove the magnetic plug for prolonged periods and do not use the meas- urement equipment during flight operations. A pressure sensor (pressure gauge with liquid damping) can be fitted instead of the mag- netic plug or the crankshaft locking screw. The magnetic plug or the crankshaft locking screw is removed and the pressure sensor is fitted.

  • Page 189: Measuring Of The Vacuum

    BRP-Rotax INSTALLATION MANUAL MEASURING OF THE VACUUM Figure 12.3: Measuring of the vacuum Oil pump housing Suction oil hose Pressure gauge with liquid damping for vacuum Measure the vacuum in the suction oil hose- from the oil tank via the oil cooler to the en- gine oil pump - at a distance of max.
  • Page 190 BRP-Rotax INSTALLATION MANUAL m WARNING Non-compliance can result in serious injuries or death! The vacuum must be verified over the complete engine operation range. If the oil is cold, the flow resistance increases, which means that not enough oil will flow on the suction side.

  • Page 191: Oil Hose Requirements

    BRP-Rotax INSTALLATION MANUAL m WARNING Non-compliance can result in serious injuries or death! At higher positioning of the oil tank, oil might leak through clearances at bearings back into crankcase. Oil tank will be empty and all oil will be in the crankcase. If fitted too low it might happen that the oil filter will be drained.

    BRP-Rotax INSTALLATION MANUAL INSTALLATION OVERVIEW Figure 12.10: Lubrication system overview Engine circuit Turbocharger return line OIL THERMOSTAT When operating at low temperatures the installation of an oil thermostat parallel to the oil cooler is highly recommended. The advantages are safe oil pressure after cold start and prevention of fuel and water accumulation in the oil.

    OIL RADIATOR (OPTIONAL) Essential parts of the cooling system, such as radiator, etc., are available for this engine from BRP-Rotax. See also SI-PAC-014.Oil radiator /-sets. m WARNING Non-compliance can result in serious injuries or death! The furnishing of proof in accordance to the latest FAR and EASA, has to be conducted by the aircraft manufacturer.
  • Page 201 BRP-Rotax INSTALLATION MANUAL Specifications of the oil radiator The radiator must be designed to dissipate approx. 30 kW (28.43 BTU/s) of thermal en- ergy at take-off performance. Weight: max. 0.82 kg (1.8 lb) for oil radiator “extra large”. NOTICE The oil radiator must not restrict oil flow. Test system as per section “Checking the oil circuit”.
