- Remove the internal chain guide.
- Remove the timing chain tensioner and slack guide.
- Place paint marks on the timing chain and sprockets to indicate the correct position of the components for installation.
- Pull lever down and release plunger stopper tab. Plunger stopper tab can be pushed up to release (coaxial structure with lever).
- Insert stopper pin into tensioner body hole to hold lever, and keep the tab released. An Allen wrench [2.5 mm (0.098 in)] is used for a stopper pin as an example
- Insert plunger into tensioner body by pressing the slack guide.
- Keep the slack guide pressed and hold it by pushing the stopper pin through the lever hole and body hole.
- Remove the timing chain tensioner installation bolts and remove the timing chain tensioner.
- Remove slack guide installation bolt and the slack guide.
- Place paint marks on the timing chain and sprockets to indicate the correct position of the components for installation.
- Remove primary timing chain and crankshaft sprocket.CAUTION: After removing timing chain, do not turn the crankshaft and camshaft separately, or the valves will strike the pistons.
- Attach a suitable stopper pin to the right and left camshaft chain tensioners (for secondary timing chains).
- Remove the intake and exhaust camshaft sprocket bolts.
- Apply paint to the timing chain and camshaft sprockets for alignment during installation.
- Secure the hexagonal portion of the camshaft using a wrench to loosen the bolts as shown.
- Remove the secondary timing chains with camshaft sprockets.
- Rotate camshaft slightly, and slacken timing chain of timing chain tensioner side.
- Insert metal or resin plate [0.5 mm (0.020 in)] into guide between timing chain and chain tensioner plunger. Remove camshaft sprocket and secondary timing chain with timing chain removed from guide groove.
- Intake camshaft sprocket is two-for-one structure of primary and secondary sprockets.
- Handle the intake sprockets as an assembly.
CAUTION:- Chain tensioner plunger can move while stopper pin is inserted in tensioner. Plunger can come out of tensioner when timing chain is removed. Use caution during removal.
- Avoid impact or dropping the intake sprockets.
- Do not disassemble the intake sprockets (never loosen bolts A and B as shown).
- Remove the timing chain tension guide.
- Remove the rear timing chain case.CAUTION:
