22. Obtain No. 1 cylinder at TDC of its compression stroke as follows:
a. Rotate crankshaft pulley clockwise to align timing mark (grooved line without color) with timing indicator.
b. Make sure that intake and exhaust cam noses on No. 1 cylinder (engine front side of right bank) are located as shown in the fig-
ure.
If not, turn crankshaft one revolution (360 degrees) and alignas shown in the figure.
23. Remove crankshaft pulley as follows:
a. Remove rear cover plate (2WD models) or starter motor (AWD models) and set the ring gear stopper (SST). Refer to EM-30, "

mary).
30. Remove timing chain (primary) and crankshaft sprocket. CAUTION:
After removing timing chain (primary), do not tu rn crankshaft and camshaft separately, or valves
will strike th e piston heads.
31. Remove timing chain (secondary) and camshaft sprockets as follows:
a. Attach suitable stopper pin to the right and left timing chain ten- sioners (secondary).
NOTE:
Use approximately 0.5 mm (0.020 in) dia. hard metal pin as astopper pin.
For removal of timing chain tensioner (secondary), refer to
EM-83, "
Component". [Removing camshaft bracket (No. 1) is
required.]
b. Remove camshaft sprocket (INT and EXH) mounting bolts. Secure the hexagonal portion of camshaft using a wrench to
loosen mounting bolts.
CAUTION:
Do not loosen the mounting bolts with securing anything
other than the camshaft hexagonal portion or with ten-
sioning the timing chain.
c. Remove timing chain (secondary) together with camshaft sprockets. Turn camshaft slightly to secure slackness of timing chain on timing chain tensioner (secondary) side.

with timing chain loose from guide groove.
CAUTION:
Be careful of plunger comi ng-off when removing timing
chain (secondary). This is because plunger of timing
chain tensioner (secondary) moves during operation,
leading to coming-off of fixed stopper pin.

and secondary sprockets.
When handling camshaft sprocket (INT), be careful of the fol-
lowing caution:
CAUTION:
Handle carefully to avoid any shock to camshaftsprocket.
Do not disassemble. (Do not loosen bolts “A” as shown in the figure).

TIMING CHAIN
In case that positions of each mating mark and each dowel pin are not fit on mating parts, make fine
adjustment to the position holding the hexagonal portion on camshaft with wrench or equivalent.
Mounting bolts for camshaft sprockets must be tightened in the next step. Tightening them by hand is
enough to prevent the dislocation of dowel pins.
It may be difficult to visually check the dislocation of mating marks during and after installation. To make the matching eas-
ier, make a mating mark on the top of sprocket teeth and its
extended line in advance with paint.
c. After confirming the mating marks are aligned, tighten camshaft sprocket mounting bolts.
Secure camshaft using a wrench at the hexagonal portion totighten mounting bolts.
d. Pull stopper pins out from timing chain tensioners (secondary).
6. Install tension guide.
7. Install timing chain (primary) as follows:
a. Install crankshaft sprocket. Make sure the mating marks on crankshaft sprocket face thefront of the engine.
b. Install timing chain (primary).

9. Install the timing chain tensioner (primary) with the following procedure:
a. Pull plunger stopper tab up (or turn lever downward) so as to remove plunger stopper tab from the rachet of plunger.
NOTE:
Plunger stopper tab and lever are synchronized.
b. Push plunger into the inside of tensioner body.
c. Hold plunger in the fully compressed position by engaging plunger stopper tab with the tip of ratchet.
d. To secure lever, insert stopper pin through hole of lever into ten- sioner body hole.
The lever parts and the tab are synchronized. Therefore, theplunger will be secured under this condition.
NOTE:
Figure shows the example of 1.2 mm (0.047 in) diamet er thin screwdriver being used as the stopper pin.
e. Install timing chain tensioner (primary). Remove any dirt and foreign materials completely from theback and the mounting surfaces of timing chain tensioner (pri-
mary).
f. Pull out stopper pin after installing, and then release plunger.
10. Make sure again that the mating marks on sprockets and timing chain have not slipped out of alignment.
11. Install new O-rings on rear timing chain case.
12. Install new front oil seal on front timing chain case. Apply new engine oil to both oil seal lip and dust seal lip.
