CAMSHAFT (w/ DPF) INSTALLATION

Note


  • When replacing the injectors (including shuffling the injectors between the cylinders), common rail or cylinder head, it is necessary to replace the injection pipes with new ones.

  • When replacing the fuel supply pump, common rail, cylinder block, cylinder head, cylinder head gasket or timing gear case, it is necessary to replace the fuel inlet pipe with a new one.

  • After removing the injection pipes and fuel inlet pipe, clean them with a brush and compressed air.


  1. INSTALL CAMSHAFTS

    A01KGB9E02

    1. Using the crankshaft pulley bolt, set the No. 1 cylinder to 90° BTDC/compression.

      Tech Tips

      Set the No. 1 cylinder to 90° BTDC/compression to avoid interference with the piston top and valve head.

    2. Install the camshaft.


      1. Apply MP grease to the thrust portion of the camshaft.

      2. Place the camshaft on the cylinder head, facing the key groove upward.

      3. A01KHB5

        Align the timing marks (1 dot mark) of the camshaft drive and driven main gears, and set the No. 2 camshaft in place.

      *1 Seal Packing
      *2 Oil Passage

      Remove any old seal packing material from the camshaft bearing cap.

    4. Apply seal packing to the specified areas shown in the illustration.

      Seal packing
      Toyota Genuine Seal Packing Black, Three Bond 1207B or equivalent
      Standard seal diameter
      4.0 mm (0.16 in.)

      Note


      • Do not allow seal packing to come into contact with the oil passage of the bearing cap.

      • After applying seal packing, install the camshaft bearing caps within 3 minutes and tighten the bolts within 15 minutes.

      • Do not start the engine for at least 2 hours after the installation.


      1. A01KEE1E01

        Install the 5 bearing caps in the proper locations.

      2. A01KGI2E02

        Apply a light coat of engine oil to the threads and under the heads of the bearing cap bolts.

      3. Install and uniformly tighten the 15 bearing cap bolts in several passes in the sequence shown in the illustration.

        19 N*m  { 194 kgf*cm, 14 ft.*lbf }
  2. INSTALL CAMSHAFT SETTING OIL SEAL


    1. Apply MP grease to the lip of a new oil seal.

    2. A01KFLPE01

      Using SST and a hammer, tap in the oil seal until its surface is flush with the oil seal retainer edge.

    *a Alignment Mark

    1. Align the alignment mark of the crankshaft pulley and timing gear case cover by rotating the crankshaft clockwise.

      Tech Tips

      Make sure that both cam-noses (intake side and exhaust side) of the No. 1 cylinder face upward.

  4. INSPECT VALVE CLEARANCE


    1. Check only the valves indicated.


      1. A01KG3PE05
        Text in Illustration
        *1 Exhaust
        *2 Intake
        *a Front

        Using a feeler gauge, measure the clearance between the valve lifter and camshaft.

        Standard Valve Clearance (Cold)
        Intake Exhaust
        0.20 to 0.30 mm (0.008 to 0.012 in.) 0.35 to 0.45 mm (0.014 to 0.018 in.)

        Write down the valve clearance measurements that are not within the specified range. These measurements will be used later to determine the size of the adjustment shim to be installed.

    2. Turn the crankshaft 360° to set the No. 4 cylinder to TDC / compression.

    3. Check only the valves indicated.


      1. A01KEKNE04
        Text in Illustration
        *1 Exhaust
        *2 Intake
        *a Front

        Using a feeler gauge, measure the clearance between the valve lifter and camshaft.

        Standard Valve Clearance (Cold)
        Intake Exhaust
        0.20 to 0.30 mm (0.008 to 0.012 in.) 0.35 to 0.45 mm (0.014 to 0.018 in.)

        Write down the valve clearance measurements that are not within the specified range. These measurements will be used later to determine the size of the adjustment shim to be installed.

  5. ADJUST VALVE CLEARANCE


    1. Remove the camshafts Click here.

    2. Remove the 8 valve lifters.

    3. A01KF1SE01

      Using a micrometer, measure the thickness of the removed lifter.

    4. Calculate the thickness of a new lifter so that the valve clearance comes within the specified value.

      A B C
      New lifter thickness Used lifter thickness Measured valve clearance
      New Lifter Thickness
      Intake A = B + (C - 0.25 mm (0.0098 in.))
      Exhaust A = B + (C - 0.40 mm (0.00157 in.))
    5. Select a new lifter with a thickness as close as possible to the calculated values.

      Tech Tips

      Valve lifters are available in 35 sizes in increments of 0.020 mm (0.0008 in.), from 5.060 mm (0.1992 in.) to 5.740 mm (0.2260 in.).

    6. Install the selected valve lifter.
