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
.
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
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).

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.

3. Hold the WAF part of oil pump shaft [WAF: 10 mm (0.39 in)] (A),
and then tighten the oil pump shaft sprocket bolt.
CAUTION:
• Secure the oil pump shaft with the WAF part.
• Never loosen the oil pump shaft sprocket bolt by tighten-
ing the oil pump drive chain.
4. Install oil pump chain tensioner (1).
• Fix the face oil pump tensioner at the most compressed posi-
tion using a stopper pin (A), and then install it.
• Securely pull out (
) the stopper pin after installing the oil
pump chain tensioner.
• Check matching mark position of oil pump drive chain and
each sprockets again.

5. Align the matching marks of each sprockets with the matching
marks of timing chain.
• If these matching marks are not aligned, rotate the camshaft
slightly by holding the hexagonal portion to correct the posi-
tion.
CAUTION:
Check matching mark position of each sprocket and timing
chain again after installing the timing chain.
6. Install the slack guide (2) and the tension guide (3).
7. Install timing chain tensioner.
• Fix the plunger at the most compressed position using a stopper pin, and then install it.
• Securely pull out the stopper pin after installing the timing chain tensioner.
CAUTION:
• After installing tensioner on the cam side, pull out lock pin.
• If plunger pops out after pulling out lock pin without installing the tensioner to the engine, never
use the tensioner. (If used, the plunger does not slide smoothly.)
• To reuse tensioner on the cam side:
After installation, pick up and move ratchet clip toward the tip of the plunger and position the
tensioner parallel to the groove of the plunger.
8. Check matching mark position of timing chain and each sprockets again.
9. Install front oil seal. Refer to
