CAUTION:

• After removing timing chains, do not turn the crankshaft and camshaft separately, or the valves will

strike the pistons.

• When installing camshafts, chain tensioners, oil seals, or other sliding parts, lubricate contacting

surfaces with new engine oil.

• Apply new engine oil to bolt threads and seat surfaces when installing camshaft sprockets, camshaft

brackets, and crankshaft pulley.

REMOVAL

1. Remove front timing chain case. Refer to 

EM-54, "Removal and Installation"

.

2. Remove the intake manifold collector. Refer to 

EM-25, "Removal and Installation"

.

3. Remove the engine oil dipstick.
4. Place paint marks on the timing chain and sprockets to indicate the correct position of the components for

installation.

5. 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 timing chain tensioner (primary) 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 guide.
d. Keep the slack 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 (pri-

mary).

6. Remove the internal chain guide (1), and slack guide (2). 

7. Remove timing chain (primary) and crankshaft sprocket.

CAUTION:

After removing timing chains, do not turn the crankshaft and camshaft separately, or the valves

will strike the pistons.

TIMING CHAIN

8. Attach a suitable stopper pin (2) to the right and left timing chain

tensioners (secondary) (1).

9. Remove the timing chains (secondary) with camshaft sprockets (INT) and (EXH).
a. Insert metal or resin plate [0.5 mm (0.020 in)] into guide between timing chain (secondary) and timing

chain tensioner (secondary) plunger. Remove camshaft sprocket and timing chain (secondary) with timing

chain removed from guide groove.

CAUTION:

Timing chain tensioner plunger can move while stopper pin is inserted in timing chain tensioner.

Plunger can come out of tensioner when timing chain is removed. Use caution during removal.

• Apply paint marks to the timing chain and camshaft sprockets for alignment during installation.

b. Remove the camshaft sprocket (INT) and (EXH) bolts.

• Secure the hexagonal portion of the camshaft using a wrench

to loosen the bolts.

• Handle the sprockets as an assembly.

c.

Remove timing chains (secondary).

CAUTION:

• Avoid impact or dropping the camshaft sprockets.

• Do not disassemble the camshaft sprockets (do not

loosen bolts (A) and (B) as shown).

10. Remove the tension guide.

INSPECTION

Check for cracks and any excessive wear of the timing chain. Replace the timing chain as necessary.

INSTALLATION

NOTE:

The figure shows the relationship between the mating mark on each timing chain and that on the correspond-

ing sprocket with the components installed.

1. Install the tension guide.
2. Position the crankshaft so No. 1 piston is set at TDC on the com-

pression stroke.

NOTE:

• Make sure that the dowel pins (A) and crankshaft key (1) are

located as shown. 

• Camshaft dowel pin (INT): at cylinder head upper face side in

each bank.

• Camshaft dowel pin (EXH): at cylinder head upper face side in

each bank.

• Crankshaft key: at cylinder head side of RH bank.

3. Install the timing chains (secondary) and camshaft sprockets.

CAUTION:

Matching marks between the timing chain and sprockets

slip easily. Confirm all matching mark positions repeatedly

during the installation process.

• Push the sleeve of the chain tensioner (secondary) and keep it

pressed in with a stopper pin.
