13. Cut liquid gasket by prying the position ( ) shown, and then
remove the front cover.
CAUTION:
Be careful not to damage the mating surface.
A more adhesive liquid gasket is applied compared to
previous types when shipped, so it should not be forced
off the position not specified.
14. Remove front oil seal from front cover.
Lift up front oil seal using a suitable tool.
CAUTION:
Be careful not to damage front cover.
15. Push in timing chain tensioner plunger.
16. Insert a stopper pin (A) into the body hole to retain the plunger in
collapsed position.
NOTE:
Use approximately 1.5 mm (0.059 in) diameter. hard metal pin
as a stopper pin.
17. Remove timing chain tensioner (1).
18. Remove timing chain slack guide (2), timing chain 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.

19. Fully lift up lever (A), and push the slack guide (B) into the inside
of chain tensioner (for oil pump) (1).
The slack guide is released by fully lifting the lever up. As the
result, the slack guide can be moved.
20. Matching the hole on lever with the hole on tensioner body,
insert a stopper pin (C) to secure slack guide.
NOTE:
Use approximately 1.0 mm (0.04 in) diameter. hard metal pin as
a stopper pin.
21. Remove chain tensioner (for oil pump).
When the holes on lever and tensioner body cannot be aligned, align these holes by slightly moving the
slack guide.
22. Hold the WAF part of oil pump shaft (A), and then loosen the oil pump sprocket bolt and remove them.
CAUTION:
Secure the oil pump shaft with the WAF part.
Never loosen the oil pump sprocket bolt by tightening the
oil pump drive chain.
23. Remove crankshaft sprocket, oil pump sprocket and oil pump drive chain as a set.
24. Remove timing chain tension guide (front cover side) from front cover if necessary.
INSPECTION AFTER REMOVAL
Timing Chain
Check timing chain and oil pump drive chain for cracks (A) and
any excessive wear (B) at the roller links of timing chain.
Replace timing chain and/or oil pump drive chain if necessary.

INSTALLATION
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. Make sure that crankshaft key points straight up.
NOTE:
*: There are two outer grooves in camshaft sprocket (INT). The wider one is a matching mark.
2. If the timing chain tension guide (front cover side) is removed, install it to the front cover.
CAUTION:
Check the joint condition by sound or feeling.
3. Install crankshaft sprocket (2), oil pump sprocket (3) and oil
pump drive chain (1).
Install it by aligning matching marks on each sprocket 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 sprocket after
installing the oil pump drive chain.

4. Hold the WAF part of oil pump shaft (A), and then tighten the oil
pump sprocket bolt.
CAUTION:
Secure the oil pump shaft with the WAF part.
Never loosen the oil pump sprocket bolt by tightening the
oil pump drive chain.
5. Install chain tensioner (for oil pump) (1).
Fix the plunger at the most compressed position using a stop-
per pin (A), and then install it.
Securely pull out ( ) the stopper pin after installing the chain
tensioner (for oil pump).
Check matching mark position of oil pump drive chain and
each sprocket again.
6. Align the matching marks of each sprocket with the matching
marks of timing chain.
NOTE:
*: There are 2 outer grooves in camshaft sprocket (INT). The
wider one is a matching mark.
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.

7. Install the timing chain tension guide (3) and the timing chain
slack guide (2).
8. Install timing chain tensioner (1).
Fix the plunger at the most compressed position using a stop-
per pin (A), and then install it.
Securely pull out the stopper pin after installing the timing
chain tensioner.
9. Check matching mark position of timing chain and each sprocket again.
10. Apply new engine oil to new front oil seal joint surface.
11. Using a suitable tool install front oil seal so that each seal lip is oriented as shown.
Press-fit front oil seal until it is flush with front end surface of
front cover as shown below with a suitable tool.
CAUTION:
Be careful not to damage front cover and crankshaft.
Press-fit oil seal straight to avoid causing burrs or tilting.
Never touch grease applied onto oil seal lip.
