Removal and Installation: Installation

WARNING: This page is about a different car, the 2004 Nissan Sentra. However, it is still accessible from the selected car via links, so may be relevant.
  1. Install the valve lifter and adjusting shims.
    • Install them in the same position from which they were removed.
    • Install adjusting shim with its stamped mark facing down (valve lifter side).
  2. Install the camshafts.
    • Intake and exhaust camshafts are distinguished by checking difference between front and rear end shapes.

  4. Tighten camshaft bracket bolts as follows.
    • Different bolts are used depending on installation location.
      1. Bolt color: 
        1. 1 to 10 in figure: black (reamer bolt) 
        2. 11 and 12 in figure: gold 
      2. Camshaft bracket bolt 
        1. Step 1 (bolts 9 - 12) :2.0 N-m (0.2 kg-m, 18 in-lb) 
        2. Step 2 (bolts 1 - 8) :2.0 N-m (0.2 kg-m, 18 in-lb) 
        3. Step 3 :5.9 N-m (0.6 kg-m, 52 in-lb) 
        4. Step 4 :9.0 - 11.8 N-m (0.92 - 1.2 kg-m, 80 - 104 in-lb)

  5. Install intake camshaft sprocket as follows.
    • Before installation, make sure that stopper pin is inserted in intake camshaft sprocket.
    NOTE: Service parts are provided with pin inserted.
    CAUTION: Stopper pin is easily detached. Secure it with vinyl tape to prevent detachment.
    1. Install timing chain by aligning the mating mark (marked when timing chain is removed) with mark on camshaft sprocket.
      • Align dowel pin on camshaft front surface and pinhole on sprocket backside, then install.

    2. While holding the hexagonal part of camshaft with a wrench, tighten intake camshaft sprocket bolt.
      • Make sure that stopper pin is not detached.
        1. Intake camshaft sprocket bolt : 78.4 -88.2 N-m (8.0 -9.0 kg-m, 58-65 ft-lb)

  6. Install exhaust camshaft sprocket as follows.
    1. Instal timing chain by aligning the mating mark (marked when timing chain is removed) with mark on camshaft sprocket.
      • Align dowel pin on camshaft front surface and pinhole on sprocket, then install.
    2. While holding the hexagonal part of the camshaft with a wrench, tighten exhaust camshaft sprocket bolt.
      1. Exhaust camshaft sprocket bolt: 98.1 - 127.5 N-m (10 - 13 kg-m, 73 - 94 ft-lb) 
    3. Make sure that mating marks on intake/exhaust camshaft sprockets and mating mark on timing chain are aligned.

  7. Install chain tensioner.
    • Hold plate and plunger with a stopper pin, then install them.
      1. Chain tensioner bolt: 6.28 -8.34 N-m (0.64 - 0.85 kg-m, 56 - 73 in-lb) 
    • After installation, remove stopper pin and release plunger.
    • Make sure again that mating marks on intake/exhaust camshaft sprockets and mating mark on timing chain are aligned.

    • The sprocket begins turning after the crankshaft does. Once sprocket start turning, keep turning crankshaft until the vane (camshaft) also begins turning. The most retarded position should now be achieved.
    • The most retarded position is confirmed when stopper pin groove is at a clockwise offset from lock pin breathing groove.
    • While turning crankshaft slightly more counterclockwise, confirm that the lock pin is engaged when vane and sprocket turn together.

  10. Install cylinder head front cover.
    • Apply Genuine Anaerobic Liquid Gasket or equivalent as shown in the figure. Refer to RECOMMENDED CHEMICAL PRODUCTS AND SEALANTS .
    • Install it by aligning the dowel pin on the cylinder head.
      1. Cylinder head front cover bolts: 6.92 - 9.51 N-m (0.71 -0.97 kg-m, 62-84 in-lb)
