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 pre-
vious 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. Press stopper tab (A) in the direction shown to push the timing
chain slack guide (B) toward timing chain tensioner (for oil
pump) (1).
 The slack guide (B) is released by pressing the stopper tab
(A). As a result, the slack guide (B) can be moved.
20. Insert stopper pin (D) into tensioner body hole (C) to secure tim-
ing chain slack guide (B).
NOTE:
Use a hard metal pin with a diameter of approximately 1.2 mm
(0.047 in) as a stopper pin.
21. Remove timing chain tensioner (for oil pump).
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.

 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.
