6.2.2 Service work at 100 hours after commissioning
Clean or replace the oil filter located in the supply pipe to the turbocharger while the en-
u

6.2.3 Service work according to instructions of enginebuilder
Clean or replace the oil filter located in the supply pipe to the turbocharger while the en-
u
gine is stopped, in accordance with the instructions of the enginebuilder.
6.2.4 Service work according to data on the rating plate
(Usually after 8000 ... 12000 operating hours)
The rotor and bearing parts must be checked and assessed by an ABB Turbocharging Service
Station. The following work can be carried out as preparation.
Remove turbocharger from engine, dismantle and measure clearances (see
u
and fitting →78).
Clean nozzle ring, turbine casing, compressor casing and diffuser, and check for cracks
u
and erosion/corrosion.
Application with frequent engine start/stop cycles (Peak shaving)
If the turbocharger is used for the 'Peak shaving' mode with frequent engine start/stop
cycles, the number of successful engine start/stop cycles must be taken into account in ad-
dition to the inspection interval for the bearing parts specified on the rating plate (in oper-
ating hours).
ABB Turbocharging recommends having the rotor and bearing parts, as well as the casing
u
parts on the turbine end, including the nozzle ring, checked and maintained by an ABB
Turbocharging Service Station after 5000 successful engine start cycles.
