CAMSHAFT INSTALLATION

PROCEDURE


  1. INSTALL CAMSHAFT TIMING GEAR ASSEMBLY

    Note

    Install the camshaft timing gear assembly onto the camshaft with the lock pin of the camshaft timing gear assembly released.

      *1 Straight Pin
      *2 Groove

      Put the camshaft timing gear assembly and camshaft together with the straight pin of the groove.

    2. Turn the camshaft timing gear assembly clockwise while pushing it gently toward the camshaft. Push further at the position where the pin fits into the groove.

      Note

      Do not turn the camshaft timing gear to the retard angle (to the right).

    3. Check that there is no clearance between the gear fringe and the camshaft.

    4. Tighten the flange bolt with the camshaft timing gear fixed.

      Torque:
      64 N*m  { 653 kgf*cm, 47 ft.*lbf }

      Note


      • Do not lock the camshaft timing gear assembly when tightening the bolt.

      • Release the lock pin of the camshaft timing gear assembly first, and tighten the bolt when the lock pin is locked in the most retarded position.

      • Tightening the bolts with the lock pin locked could cause breakage of the lock pin.

    5. Check that the camshaft timing gear assembly can move to the retard angle (to the right) and is locked in the most retarded position.

  2. INSTALL CAMSHAFT


    1. Apply a light coat of engine oil to the camshaft and camshaft journals.

      *a Paint Mark
      *b Timing Mark

      Install the chain onto the camshaft timing gear with the paint mark and the timing mark aligned as shown in the illustration.

    3. A005JGOE01

      Examine the front marks and numbers on the No. 2 camshaft bearing cap and check that the sequence is as shown in the illustration. Then uniformly tighten the bolts, in several steps, in the sequence shown in the illustration.

      Torque:
      13 N*m  { 129 kgf*cm, 9 ft.*lbf }

      Note

      Tighten each bolt uniformly while keeping the camshaft level.

  3. INSTALL NO. 2 CAMSHAFT


    1. Install the No. 2 camshaft.

    2. A005GGJE08

      *1 Pin
      *a Paint Mark
      *b Timing Mark

      Hold the chain and align the timing mark on the camshaft timing sprocket with the paint mark of the chain.

    3. Align the alignment pin hole in the camshaft timing sprocket with the alignment pin of the camshaft, and install the sprocket onto the camshaft.

    4. Provisionally install the flange bolt.

      *1 No. 1 Bearing Cap
      *2 No. 2 Bearing Cap

      Examine the front marks and numbers on the No. 1 and No. 2 camshaft bearing caps and check that the order is as shown in the illustration. Then uniformly tighten the bolts, in several steps, in the sequence shown in the illustration.

      Torque:
      13 N*m  { 129 kgf*cm, 9 ft.*lbf }
      for No. 2 bearing cap
      23 N*m  { 235 kgf*cm, 17 ft.*lbf }
      for No. 1 bearing cap

      Note

      Tighten each bolt uniformly while keeping the camshaft level.

    6. A005LRF

      Using a union nut wrench, hold the hexagonal lobe of the No. 2 camshaft and install the flange bolt.

      Torque:
      for use without union nut wrench
      64 N*m  { 653 kgf*cm, 47 ft.*lbf }
      for use with union nut wrench
      59 N*m  { 602 kgf*cm, 44 ft.*lbf }

      Tech Tips


      • This torque value can be obtained by using a torque wrench with a fulcrum length of 300mm (11.8 in.) and a union nut wrench with a fulcrum length of 25mm (0.984 in.) Click here.

      • This torque value is effective when the union nut wrench is parallel to the torque wrench.

    7. Remove the bar from the timing chain tensioner.

      *a Paint Mark
      *b Timing Mark

      Check that all the pairs of timing marks are aligned.

    10. Apply adhesive to 2 or 3 threads of the screw plug end.

      Adhesive
      Toyota Genuine Adhesive 1324, Three Bond 1324 or equivalent

    11. Using an 8 mm (0.31 in.) hexagon wrench, install the screw plug.

      Torque:
      15 N*m  { 153 kgf*cm, 11 ft.*lbf }
