4.2 Inspection procedures
4.2.1 Introduction
Inspection procedures include preventative visual controls, monitoring and measuring work
before and during commissioning. Inspection procedures enable changes to the turbochar-
ger to be detected. Machine damage can be prevented.
4.2.2 Checks before commissioning
Filter mat (if available)
u Check for damage and contamination.
Lubricating system
CAUTION
Contaminated oil
Serious damage to engine or property can be caused by dirt and solid ma-
terial particles in the oil.
u For the initial commissioning phase and after all service work, flush the
complete lubricating system with warm oil.
u Use special running-in filters when running in the engine and after all ser-
vice work on the lubricating system.
u Check that the oil filter is clean before commissioning.
u Check the oil pressure in the oil supply pipes.
Warning plates
u Check whether warning plates are present and legible.
u Check whether the protective sheets have been removed from new warning plates.

CAUTION
Failure of compressor wheel cooling
Any prolonged failure of the compressor wheel cooling will shorten the re-
placement interval of the compressor wheel.
u Make sure there is an uninterrupted supply of cooling air during opera-
tion.
u Check whether the compressor wheel cooling is fitted on the bearing casing.
