  1. MAINTENANCE PRECAUTION


    1. A003CX9

      Pay due attention when removing and reinstalling the turbocharger sub-assembly. Do not drop, strike, or grasp easily-deformed assembly parts.

      Note:

      • Do not hold the actuator or control rod.

      • A003GE9

        When storing the turbocharger sub-assembly, do not store the assembly with the actuator facing down.

      • Make sure foreign matter does not enter the intake and exhaust ports and oil passage.

    2. A003H6HE01

      If replacing the turbocharger sub-assembly, check for deposits in the turbo oil inlet pipe sub-assembly.

      Table 1. Text in Illustration

      *a Sludge

      If necessary, replace the turbo oil inlet pipe sub-assembly.

    3. Thoroughly remove any old gasket material sticking to the lubrication oil pipe flange or turbocharger sub-assembly oil flange.

    4. If replacing the bolts or nuts, use TOYOTA genuine parts to prevent breakage or deformation.

    5. A003ICME01

      If replacing the turbocharger sub-assembly, add 20 cc (1.2 cu. in.) of fresh oil into the turbocharger sub-assembly oil inlet hole and turn the turbine wheel by hand to spread oil over the bearing.

    6. If overhauling or replacing the engine, cut the fuel supply after reassembly and crank the engine for 30 seconds to distribute oil throughout the engine. Then reconnect the fuel supply and allow the engine to idle for 60 seconds.

    7. Since the turbine wheel runs at an extremely high speed, if the engine is running without the air cleaner, air cleaner cap and hose, the turbine wheel will be damaged due to the entry of foreign particles.
