4.4.6. Periodical checking and 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.
