TURBOCHARGER INSPECTION [MZR-CD (RF Turbo)]


BME011313700W01

Note
• If the following problems exist, diagnosis the turbocharger using the following symptom troubleshooting procedures.

1. Lack of power: perform "NO.12 LACK/LOSS OF POWER". (See NO.12 LACK/LOSS OF POWER-ACCELERATION/CRUISE [MZR-CD (RF Turbo)].)

2. Oil leak: perform "NO.16 HIGH OIL CONSUMPTION/LEAKAGE". (See NO.16 HIGH OIL CONSUMPTION/LEAKAGE [MZR-CD (RF Turbo)].)

3. Noise: perform "NO. 21 ENGINE NOISE". (See NO.21 ENGINE NOISE [MZR-CD (RF Turbo)].)

Compressor Wheel Inspection

1. Remove the air pipe between the air cleaner and the turbocharger. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [MZR-CD (RF Turbo)].)

2. Visually inspect the compressor wheel from view A and verify that all fins are free from damage, cracks or bends.

• If there are damaged fins, cracks or bends, replace the turbocharger.
Note
• To make the inspection easier, set a small mirror as shown in the figure and use a penlight.
• If the compressor wheel is interfering with the compressor housing, it is likely that the fin edges are cracked, damaged, or bent.
• If the compressor wheel is damaged, check the following before replacing the turbocharger to avoid reoccurrence of the problem.
- Foreign material in intake air/exhaust system.
- Oil pipe clogging.

Turbine Wheel Inspection

1. Remove the joint pipe between the air cleaner and the turbocharger. (See EXHAUST SYSTEM REMOVAL/INSTALLATION [MZR-CD (RF Turbo)].)

2. Visually inspect the turbine wheel from view B and verify that all fins are free from damage, cracks or bends.

• If there are damaged fins, cracks or bends, replace the turbocharger.
Note
• To make the inspection easier, set a small mirror as shown in the figure and use a penlight.
