85-30-64 Installation of parts attached to the cylinder head
1. Install the glow plugs – refer to Chapter 80-00-22.
2. Install the injectors – refer to Chapter 73-00-12.
3. Install the common rail – refer to Chapter 73-00-62 (same procedure as installation of the rail
pressure sensor).
4. Install the high pressure pump (HPP) – refer to Chapter 73-00-44.
5. Install the intake air manifold – refer to Chapter 85-30-12 – CHECK if all sensors are installed.
6. Install the exhaust manifold – refer to Chapter 78-00-12 – CHECK if the turbo charger is
installed.
7. Install the gasket of the oil return line – refer to Chapter 79-00-114.
8. Install the oil return line – refer to Chapter 79-00-112.
9. Install the sealing ring of the lubricant line – refer to Chapter 79-00-104.
10. Install the lubricant line – refer to Chapter 79-00-102.
11. Install the wiring harness – refer to Chapter 71-50-170 – re-connect all affected sensors.
12. Install the oil return line at the oil separator – refer to Chapter 79-00-92.
13. Install the injector cover – refer to Chapter 85-00-12.
For assembly of A/C related installation refer to the respective A/C Maintenance Manual.
14. Fill the engine with coolant and bleed the cooling system – refer to the applicable Aircraft
Maintenance Manual.
15. Perform ground run according to Chapter 71-00-03
16. Conduct the power evaluation.
If power evaluation before replacement has been conducted under wind conditions ensure
that the following evaluation will be conducted under similar wind conditions (direction,
wind strength).
● Start cold engine, bring temperatures to normal operation conditions (50°C Engine Oil Temp,
60°C Coolant Temp, 35°C Gearbox Oil Temp)
● Start Recording with attached LiveView-Config
● Perform Selftest
● Bring Power lever to Max. Continuous Power
● Record 30s on ECU A, then 30s on ECU B
● Bring Power Lever to Idle and stop LiveView-Recording
● Collect and store the after replacement recorded data
● Send the data collected prior to the replacement and after the replacement of the cylinder
head to Austro Engine GmbH.
Expected Results:
● Total selftest runtime before/after the test almost the same (same engine power after change
of cylinder head)
● At Max Continuous Power almost same rates of boost pressure actuation (intake and exhaust
airtight).
● Smooth engine run on ECU B (camshaft system correctly configured).
Before determining the airworthiness Austro Engine has to check the collected power
evaluation data and confirm that no power loss has occurred.
