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 low and
high-pressure stage to be detected. Engine 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.
Water cooling in the bearing casing (if present)
u
Check whether the water pipes are fitted on the bearing casing.
CAUTION
Failure of the bearing casing cooling
Any prolonged failure of the water cooling will negatively affect the oil tight-
ness of the low-pressure or high-pressure stage and increase their thermo-
mechanical fatigue.
u
Ensure the correct assembly of the water pipes and the cooling water
supply.
