LUBRICATION SYSTEM ON-VEHICLE INSPECTION


  1. TILT UP CAB

    CAUTION:


    • Make sure that the vehicle is on a level surface before tilting the cab up.

    • Make sure that all the doors are closed before tilting the cab up.

    • Make sure that nobody is inside or near the cab when tilting it up.

    • Be sure to have 2 people tilt the cab up when a heavy object such as a roof rack or cargo carrier is installed to the cab.

    • Be sure to remove anything set on top of the cab before tilting it up.

    • Make sure that the cab is securely locked in place after it is tilted up.

    • Make sure that there are no tools, cloths, etc. left in the engine room before tilting the cab back down.

    • Make sure that the cab is securely locked in place after tilting it back down.

  2. INSPECT OIL QUALITY


    1. Check the engine oil for deterioration, water contamination, discoloration or thinning. If the quality is visibly poor, replace the engine oil and oil filter sub-assembly Click here.

  3. INSPECT ENGINE OIL LEVEL

      Text in Illustration
      *1 Low Level Mark
      *2 Full Level Mark
      *3 Full Level Mark (For Inspection)

      Warm up the engine, stop the engine and wait 5 minutes. The engine oil level should be between the dipstick low level mark and full level mark (for inspection). If low, check for leakage and add oil up to the full level mark.

      Note

      Do not fill engine oil above the full level mark.

      Tech Tips

      A certain amount of engine oil will be consumed while driving. In the following situations, oil consumption may increase, and engine oil may need to be refilled in between oil maintenance intervals.


      • When the engine is new, for example directly after purchasing the vehicle or after replacing the engine.

      • If low quality oil or oil of an inappropriate viscosity is used.

      • When driving at high engine speed or with a heavy load, (when towing, or), when driving while accelerating or decelerating frequently.

      • When idling for a long time, or when driving frequently through heavy traffic.

      When judging the amount of oil consumption, keep in mind that the oil may have become diluted, making it difficult to judge the true level accurately.

  4. INSPECT ENGINE OIL PRESSURE

      *1 Engine Oil Pressure Switch Assembly
      *2 Union Bolt
      *3 Gasket
      *4 Union
      *5 Adapter
      *6 Oil Pressure Gauge

      Install the union and 2 new gaskets to the turbo oil inlet pipe sub-assembly with the union bolt.

      Torque:
      25 N*m  { 250 kgf*cm, 18 ft.*lbf }

      Tech Tips

      Part No.

      Union bolt 90034-01011
      Union 90404-10024
      Gasket SZ430-10005

    3. Install an oil pressure gauge with an adapter.

    4. Warm up the engine.

    5. Measure the engine oil pressure.

      Standard Oil Pressure
      Condition Specified Condition
      Idle

      190 kPa (1.9 kgf/cm2, 27.6 psi)

      If the pressure is not as specified, check the oil pump assembly.

    6. Remove the oil pressure gauge and adapter.

    7. Remove the union bolt, union and 2 gaskets.

    8. Install the engine oil pressure switch assembly Click here.

    9. Inspect for engine oil leaks.
