Cam shaft: Installation

WARNING: This page is about a different car, the 2012 Subaru Forester. However, it is still accessible from the selected car via links, so may be relevant.
  1. Install the camshaft.

    Apply engine oil to the cylinder head at camshaft bearing installation location before installing the camshaft. Install the camshaft so that each valve is close to or in contact with base circle of the cam lobe.

    NOTE:
    • Set the camshaft to the position shown in the illustration.
    • When set at the position shown in the illustration, it is not necessary to rotate the camshaft RH when installing the timing belt, but it is necessary to rotate the camshaft LH slightly.

    Intake camshaft LH: 

    Rotate 80° clockwise. 

    Exhaust camshaft LH: 

    Rotate 45° counterclockwise.

  2. Install the camshaft cap.
    1. Apply small amount of liquid gasket to the mating surface of cap.
      NOTE:
      • Install within 5 min. after applying liquid gasket.
      • Do not apply liquid gasket excessively. Applying excessively may cause excess gasket to come out and flow toward oil seal, resulting in oil leak.

      Liquid gasket: 

      THREE BOND 1217G (Part No. K0877Y0100) or equivalent 

      Liquid gasket applying diameter: 

      Mating surfaces other than ranges A and B 2±0.5 mm (0.0787±0.0197 in) 

      Mating surfaces of ranges A and B 3±1 mm (0.1181±0.0394 in)

    2. Apply a thin coat of engine oil to the cap journal surface, and install the camshaft cap to the camshaft.
    3. Gradually tighten the camshaft cap in at least two steps, in alphabetical order shown in the illustration, and then tighten to the specified torque.

      Tightening torque: 

      T1: 9.75 N.m (1.0 kgf-m, 7.2 ft-lb) 

      T2: 20 N.m (2.0 kgf-m, 14.8 ft-lb)

    4. After tightening the camshaft cap, ensure the camshaft rotates only slightly while holding it at base circle.
  3. Apply a thin coat of engine oil to the periphery of the camshaft oil seal and oil seal lip, and install the oil seal on the camshaft using ST1 and ST2.
    NOTE: Use a new oil seal.
