6.2.4 Service work every 12000 ... 16000 hours of operation
The rotor and bearing parts must be checked and assessed by a Turbo Systems service sta-
tion.
u
Dismantle low-pressure and high-pressure stage. Measure clearances.
u
Clean nozzle ring and casing and check for cracks and erosion/corrosion.
Additional measures in conjunction with the high-pressure stage:
u
Replace gaskets every time after disassembly.
u
Check bellows between air-inlet casing and compressor casing for cracks and clean (see

Replacement of the bearing parts
¡ Replacement of the turbine and the compressor.
6.2.6 Entries in the engine logbook
The monitoring of the engine enables conclusions to be drawn on the behaviour of the low-
pressure and high-pressure stage.
The following operating data and measured values must be entered regularly in the engine
logbook of the enginebuilder:
¡
Performance and speed of the engine
¡
Air intake temperature
¡
Pressure of the charge air
¡
Pressure loss in the charge air cooler and intercooler
¡ Lubricating oil pressure and lubricating oil temperature
If present:
¡
Speed of low-pressure and high-pressure stage
¡
Air temperature before and after the compressor and after the charge air cooler
¡
Exhaust gas temperature before and after the turbine
¡
Atmospheric humidity of the suction air (before the low-pressure stage)
