2. Remove the intake manifold collector. Refer to
EM-146, "Removal and Installation".
3. Place paint marks on the timing chain and sprockets to indicate the correct position of the components for
installation.
4. Remove the timing chain tensioner (primary).
a. Pull lever down and release plunger stopper tab. Plunger stop- per tab can be pushed up to release (coaxial structure with
lever).
b. Insert stopper pin into tensioner body hole to hold lever, and keep the tab released. An Allen wrench [1.2 mm (0.047 in)] is
used for a stopper pin as an example.
c. Insert plunger into tensioner body by pressing the slack side chain guide.
d. Keep the slack side chain guide pressed and hold it by pushing the stopper pin through the lever hole and body hole.
e. Remove the bolts and remove the timing chain tensioner.
5. Remove the internal chain guide, and slack guide.
6. Remove primary timing chain and crankshaft sprocket. CAUTION:
After removing timing chain, do not turn the crankshaft and camsh aft separately, or the valves will
strike the pistons.
7. Attach a suitable stopper pin to the right and left camshaft chain tensioners (for secondary timing chains).
8. Remove timing chain (secondary) and camshaft sprockets as follows:

INSPECTION
Check for cracks and any excessive
wear of the timing chain. Replace the timing chain as necessary.
INSTALLATION
NOTE:
The illustration shows the relationship between the mating mark on each timing chain and that on the corre-
sponding sprocket, the components installed.
1. Install the timing chain tension guide.
2. Check that dowel pin (A) and crankshaft key (1) are located as shown. (No. 1 cylinder at compression TDC)
NOTE:
Though camshaft does not stop at the position as shown, for the
placement of cam nose, it is generally accepted camshaft is
placed in the same direction.

4. After confirming the mating marks are aligned, tighten the cam-
shaft sprocket bolts.
• Secure the camshaft using a wrench at the hexagonal portion
to tighten the bolts.
5. Pull the stopper pins out from the secondary timing chain ten- sioners.
6. Install the crankshaft sprocket on the crankshaft. • Make sure the mating marks on the crankshaft sprocket facethe front of the engine.
7. Install the primary timing chain. • Install primary timing chain so the mating mark (punched) (B)
on camshaft sprocket (C) is aligned with the pink link (A) on
the timing chain, while the mating mark (notched) (E) on the
crankshaft sprocket (D) is aligned with the orange one (F) on
the timing chain, as shown.
• When it is difficult to align mating marks of the primary timing chain with each sprocket, gradually turn the camshaft using a
wrench on the hexagonal portion to align it with the mating
marks.
• During alignment, be careful to prevent dislocation of mating
mark alignments of the secondary timing chains.
