Turbocharger (turbocharger) is removed during engine repair, replacement of gaskets, and when replacing the turbocharger itself

Turbocharger is not allowed to be disassembled and repaired.

Turbocharger condition should be checked by rotor run-out time when diesel engine is stopped.

For this, after 3...5 minutes of operation at minimum idle speed, diesel engine is brought to maximum speed mode, after which fuel supply is turned off.

Turbocharger rotor rotation after diesel engine is stopped should be heard for at least 5 s.

Even, constant level sound with gradual attenuation indicates normal condition of turbocharger,

One of the reasons for decreased diesel power and increased smoking may be a decrease in pressure boost due to contamination of the compressor flow path, which can be determined by the tight rotation of the rotor.

If the rotor rotates tightly, it is necessary to partially disassemble the turbocharger and flush the compressor part.
