Remove the timing chain tensioner (1) and slack guide (6).
- Place paint marks on the timing chain and sprockets to indicate the correct position of the components for installation.
  1. Pull lever (4) down and release plunger stopper tab (2). Plunger stopper tab (2) can be pushed up to release [coaxial structure with lever (4)].
    - ←: pull lever
  2. Insert stopper pin (3) into tensioner body hole to hold lever (4), and keep the tab (2) released. An Allen wrench [2.5 mm (0.098 in)] (3) is used for a stopper pin as an example.
  3. Insert plunger (5) into tensioner body hole by pressing the slack guide (6).
    - ←: Press slack guide
  4. Keep the slack guide (6) pressed and hold it by pushing the stopper pin (3) through the lever hole and body hole as shown.
  5. Remove the timing chain tensioner installation bolts (7) and remove the timing chain tensioner (1).
  6. Remove slack guide installation bolt and the slack guide (6).
Remove primary timing chain and crankshaft sprocket.
