TIMING CHAIN

a. Fix crankshaft pulley (1) with a pulley holder (commercial ser-

vice tool) (A), loosen crankshaft pulley bolt, and locate bolt seat-

ing surface at 10 mm (0.39 in) from its original position.

CAUTION:

Never remove the crankshaft pulley bolt as they will be

used as a supporting point for the pulley puller [SST:

KV11103000 ( — )].

b. Attach a pulley puller [SST: KV11103000 ( — )] (A) in the M6

thread hole on crankshaft pulley (1), and remove crankshaft pul-

ley. 

5. Remove oil pan (lower). Refer to 

EM-110, "Exploded View"

.

NOTE:

If crankshaft sprocket and oil pump drive component are not removed, this step is unnecessary.

6. Remove intake valve timing control solenoid valve and exhaust valve timing control valve.
7. Remove drive belt auto-tensioner. Refer to 

EM-75, "Exploded View"

.

8. Remove front cover with the following procedure:
a. Loosen mounting bolts in reverse order as shown in the figure.

b. Cut liquid gasket by prying the position (

) shown in the figure,

and then remove the front cover.

CAUTION:

• Be careful not to damage the mating surface.

• A more adhesive liquid gasket is applied compared to pre-

vious types when shipped, so it should not be forced off

the position not specified.

9. Remove front oil seal from front cover. 

CAUTION:

Be careful not to damage front cover.

• Lift up front oil seal using a screwdriver.

10. Remove valve timing control cover, if necessary.

• Loosen mounting bolts in reverse order as shown in the figure.

NOTE:

Disregard the numerical order No.1 in removal.

11. Remove timing chain tensioner with the following procedure:
a. Insert a wire (A) (e.g. clip) into the top groove with the timing

chain tensioner plunger pressed. 

NOTE:

Timing chain tensioner plunger is securely fixed by inserting a

wire (e.g. clip).

b. Remove timing chain tensioner (1).

TIMING CHAIN

12. Remove slack guide (2), tension guide (3) and timing chain (1).

CAUTION:

Never rotate each crankshaft and camshaft individually

while timing chain is removed. It causes interference

between valve and piston.

NOTE:

If timing chain is difficult to remove, remove camshaft sprocket

(EXH) first to remove timing chain.

13. Remove crankshaft sprocket and oil pump drive component with the following procedure:
a. Push oil pump drive chain tensioner (1) in the direction show in

the figure.

b. Insert a stopper pin (A) into the body hole (B).
c.

Remove oil pump chain tensioner.

• When the holes on lever and tensioner body cannot be

alirned, align these holes by slightly moving the oil pump chain

tensioner slack guide.

d. Hold the WAF part of oil pump shaft [WAF: 10 mm (0.39 in)] (A),

and then loosen the oil pump sprocket bolt and remove it.

CAUTION:

• Secure the oil pump shaft with the WAF part.

• Never loosen the oil pump sprocket bolt by tightening the

oil pump drive chain.

INSTALLATION

CAUTION:

Do not reuse O-rings.

NOTE:

The figure shows the relationship between the matching mark on

each timing chain and that on the corresponding sprocket, with the

components installed.

1. Check that crankshaft key points straight up.
2. Install crankshaft sprocket (2), oil pump sprocket (3), and oil

pump drive chain (1).

• Install it by aligning matching marks on each sprockets and oil

pump drive chain. 

• If these matching marks are not aligned, rotate the oil pump

shaft slightly to correct the position.

CAUTION:

Check matching mark position of each sprockets after

installing the oil pump drive chain.
