a. Rotate crankshaft pulley (2) clockwise and align TDC mark
(without paint mark) (A) to timing indicator (1) on front cover.
b. Make sure the matching marks on each camshaft sprocket are
positioned as shown.
 If not, rotate crankshaft pulley one more turn to align matching
marks to the positions.
8. Remove crankshaft pulley with the following procedure:
a. Secure crankshaft pulley (1) using a suitable tool (A).
b. Loosen and pull out crankshaft pulley bolts.
CAUTION:
Never remove the mounting bolts as they are used as a sup-
porting point for the pulley puller.

9. Remove front cover with the following procedure:
a. Loosen bolts in the reverse of the order shown.
b. Cut liquid gasket by prying the position ( ) shown, and then
remove the front cover.
10. Remove front oil seal from front cover.
 Remove by lifting it up using a suitable tool.
CAUTION:
Be careful not to damage the front cover.
11. Remove chain tensioner (1) with the following procedure.
a. Fully push down the chain tensioner lever (A), and then push the
plunger (C) into the inside of tensioner.
 The tab (B) is released by fully pushing the lever down. As a
result, the plunger can be moved.
b. Pull up the lever to align its hole position with the body hole posi-
tion.
 When the lever hole is aligned with the body hole position, the
plunger is fixed.
 When the protrusion parts of the plunger ratchet and the tab
face each other, both hole positions are not aligned. At that
time, correctly engage them and align these hole positions by
slightly moving the plunger.
c. Insert the stopper pin (D) into the body hole through the lever hole, and then fix the lever at the upper
position.
 The example that a hexagonal wrench for 2.5 mm (0.098 in) is used as shown.
d. Remove chain tensioner.

TIMING CHAIN
The illustration shows the relationship between the matching mark
on each timing chain and that on the corresponding sprocket, with
the components installed.
1. Install the crankshaft sprocket and the oil pump drive related parts with the following procedure:
a. Install the crankshaft sprocket (1), the oil pump drive chain (2),
and the oil pump sprocket (3) at the same time.
 Install the crankshaft sprocket so that its invalid gear area (A)
is towards the back of the engine.
 Install the oil pump sprocket so that its hexagonal surface
faces (B) the front of engine.
NOTE:
There is no matching mark in the oil pump drive related parts.
b. Hold the top of the oil pump shaft using the TORX socket (size:
E8), and then tighten the oil pump sprocket nuts.

c. Install chain tensioner (1).
 Insert the body into the shaft (B) while inserting the spring into
the fixing hole (A) of cylinder block front surface.
 Make sure that the tension is applied to the oil pump drive
chain after installing.
2. Install timing chain with the following procedure.
 Install by aligning matching marks on each sprocket and tim-
ing chain.
 If these matching marks are not aligned, rotate the camshaft
slightly to correct the position.
CAUTION:
 Check matching mark position of each sprocket and tim-
ing chain again after installing the timing chain, keep
matching marks aligned by holding them with a hand.
 To avoid skipped teeth, never rotate crankshaft and cam-
shaft until front cover is installed.
3. Install timing chain tension guide (2) and timing chain slack
guide (1).
4. Install 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 chain ten-
sioner.
