Inspection

INSPECTION PROCEDURE

Turbocharger Trouble Diagnosis [Oil Leaks, Smoke (white/blue), Lack of Power, Poor Acceleration, Unusual Noise]

Check that the engine oil amount is the specified level.

Interview the customer about whether the engine oil is cooled down by idling after driving.

Diagnosis

• Refer to the table below and check each of the parts.

• For the inspection methods, refer to "INSPECTION AFTER REMOVAL."

Inspection location	Check result	Symptoms likely to occur when the results shown on the left exist.
		Oil leaks	Smoke	Noise	Low power Poor acceleration
Turbine wheel	Oil is leaking.
	Carbon deposits are observed.
	There are marks from rubbing against housing.
	Vane is bent or broken.
Compressor wheel	Inside of intake port is badly stained with oil.
	There are marks from rubbing against housing.
	Vane is bent or broken.
Rotor shaft	Heavy feel or catching when turned by hand.
	Cannot be turned by hand.
	Excessively loose bearing.
Oil return port	Carbon or sludge deposit in oil drain port.

: Highly possible.

: Possible.

: May exist.

INSPECT ION AFTER REMOVAL

Perform the following checks. If any adhering material is found, perform cleaning. If any irregularities are found, or if the value is outside the standard, replace the turbocharger.

• Refer to the figure for the names of parts and the locations for visual inspection.

• If the compressor wheel, turbine wheel, rotor shaft, or other internal part is damaged, check the following paths and completely remove all fragments and other foreign material for preventing secondary malfunctions.

  Intake side:	From turbocharger to charge air cooler From turbocharger to air cleaner
  Exhaust side:	From turbocharger to catalyst

Cleaning Work

• Clean before checking.

  • Use engine conditioner to clean the oil feed and return ports.

    

  • Use radiator cleaner to clean the water feed and return ports.

• After cleaning, air-blow using an air gun.

• Air-blow the compressor wheel, turbine wheel, compressor housing, and turbine housing.

Turbine Wheel and Compressor Wheel

• Check visually, and by other means, for adhering oil.

• Check visually, and by other means, for adhering carbon.

• Check for bent or broken vanes.

• Check for interference with the housing.

Rotor Shaft

• Rotate rotor shaft by hand and check that it turns smoothly without resistance or sticking.

  

• Shake rotor shaft vertically and horizontally and check for looseness.

Surface Distortion

• Using suitable tool (A) and suitable tool (B), check the surface distortion of turbocharger mating surface.

  

  Limit

  : Turbocharger

• If it exceeds the limit, replace turbocharger.

INSPECTION AFTER INSTALLATION

Start the engine and increase the engine speed. Check for engine oil leaks, exhaust gas leaks and engine coolant leaks.
