    1. Pull lever down and release plunger stopper tab.
      • Plunger stopper tab can be pushed up to release (coaxial structure with lever).
    2. Insert stopper pin into tensioner body hole to hold lever, and keep tab released.
      NOTE: Allen wrench [2.5 mm (0.098 in)] is used for stopper pin as an example.

    3. Insert plunger into tensioner body by pressing slack guide.
    4. Keep slack guide pressed and hold it by pushing stopper pin through the lever hole and body hole.
    5. Remove mounting bolts and remove timing chain tensioner.

  21. Remove timing chain (primary) and crankshaft sprocket.
    CAUTION: After removing timing chain (primary), do not turn crankshaft and camshaft separately, or valves will strike the piston heads.
  22. Remove timing chains (secondary) and camshaft sprockets with the following procedure:
    1. Attach suitable stopper pin to RH and LH timing chain tensioners (secondary).
      NOTE: For removal and installation of timing chain tensioner (secondary), refer to CAMSHAFT  . [Removing camshaft bracket (No. 1) is required.]

    2. Remove intake and exhaust camshaft sprocket bolts.
      • Apply paint to timing chain and camshaft sprockets for alignment during installation.
      • Secure the hexagonal portion of camshaft using wrench to loosen mounting bolts.

    3. Remove timing chain (secondary) together with camshaft sprockets.
      • Turn camshaft slightly to secure slackness of timing chain on chain tensioner side.
      • Insert 0.5 mm (0.020 in) thick metal or resin plate between timing chain and chain tensioner plunger (guide). Remove timing chain (secondary) together with camshaft sprockets with timing chain loose from guide groove.
        CAUTION: Be careful of plunger coming-off when removing timing chain. This is because plunger of chain tensioner moves during operation, leading to coming-off of fixed stopper pin.
        NOTE: Camshaft sprocket (INT) is two-for-one structure of primary and secondary sprockets.

      • When handling camshaft sprocket (INT), be careful of the following:
        CAUTION:
        • Handle carefully to avoid any shock to camshaft sprocket.
        • Do not disassemble. (Never loosen bolts "A" and "B" as shown).
