3) Lubricating system
Care should be taken in dealing with oil quality and replacement timing of the oil
filter cartridge of the lubrication system.
Degradation of engine oil can have significantly adverse effects on the engine body
as well as the turbocharger.
The oils recommended for the engine mounted with the turbocharger are as follows :
Engine oil SAE no. API no.

5.3.6. Periodical servicing
Make it a rule to check the turbocharger assembly for condition and contamination
periodically.
1) Guide for checking the rotor for rotating condition
The inspection of the rotor assembly for rotating condition should be performed by the
degree of unusual sound. If a sound detecting bar is used, install its tip on the
turbocharger housing and increase the engine revolutions slowly. If a high-pitch sound
is heard continuously, it means that the rotor assembly is not normal. In this case, as
the metal bearing and rotor are likely to be in abnormal conditions, the turbocharger
should be replaced or repaired.
2) Guide for checking rotor end play
Disassemble the turbocharger from the engine, then check the rotor axial play and
radial play. When disassembling the turbocharger, be sure to plug the oil inlet and
outlet ports with taps, etc
