3.2 Inspection work

This inspection work includes preventive visual controls, as well as monitoring and measurement to ensure the correct functioning of the turbocharger. These serve as an aid to detecting anomalies before and during commissioning, thus preventing possible damage to the machine.

·         The safety instructions must be followed before and during all inspection work.

3.2.1 Inspection before commissioning

Monitoring equipment
·         To be checked for correct functioning.
Air filter mat
·         Inspect for damage.
Lubricating system
·         Check oil filter for cleanliness before commissioning.


It is urgently recommended that the entire lubrication system be flushed thoroughly with warm oil using a bypass pipe before commissioning and after every servicing operation on the lubrication system. We strongly recommend the use of a starting filter when running the engine in and after every servicing operation on the.

lubrication system.

·         Check oil pressure in oil supply lines.
·         Ensure that the VTG unit can be adjusted.
3.2.2 Inspection after commissioning

Lubricating system
·         Check oil pressure in oil supply lines.

Charger speed
·         Measuring
Charger pressure
·         Measuring

·   Measure upstream/downstream from turbine, compressor and oil feed for various engine speeds

Gas, air, and oil lines
·         After the engine has been started up, check all gas, air and oil lines for leaks.

Further must be observed:

Lubricants and pastes are liquefied or vaporised during assembly of the turbocharger and may escape as an oily liquid in the first few hours after commissioning. If oily liquid continues to escape after this period, the cause must be treated as an oil leak and located. The first step in this process is to check the oil supply to the turbocharger for leaks. If this is not in order, contact an official ABB Turbo Systems service station.
·    Measure the speed, oil pressure, charging pressure and temperatures before and after the turbine and the compressor at various engine speeds.
·      Compare the measured values with those of the inspection report, taking into account the different operating conditions.

·         Check the functioning of the VTG unit.

3.2.3 Inspection after 100 service hours
Clean or replace lubricating oil filters after the first 100 service hours.
