mark to get the No.1
cylinder's piston be in TðC position (compression stroke).
At this time, the timing
marks of the camshaft sprocket and cylinder head cover
should coincide with each
'. Remove the timing bell.

rotating direction on
the belt so as to install correctly.

3. Install the crankshaft sprocket.
Notice: Confirm if timing marks coincide with.
Caution: Align the spacer with a pin, and assemble it
exerting even force not to
deform the crankshaft sensing blade.
4. Install the camshaft sprocket. Align it like initial
state as shown.
Caution: When installing camshaft sprocket, tighten the bolt

excessively, be cautious not to
rotate more than the initial stable position. Always align
timing mark of rotating
sprocket by turning it reversely. In this case, pay
attention not to rotate It
reversely from the initial position. (if. with one sprocket
fixed at No.1
compression TDC position, the other sprocket is rotated one
clockwise or counterclockwise, then the intake and exhaust

tighten the center bolt
9. Pull out the auto tensioner set pin
How to adjust timing belt tension
1. Tension setting (While auto tensioner is not operating:
And set pin being kept
1) After rotating crankshaft 1/4 revolution reversely, rotate it clockwise to position
No.1 cylinder at TDC. Then, loosen the center bolt and give
the belt 50 kg-cm of
tension with tensioner pulley socket (Two pins are attached)
and torque wrench.
While maintaining this state, tighten the center bolt to the
Center bolt standard torque 43 - 55 Nm (430 - 550 kg-cm,

2) Pull out the auto tensioner fixing pin.
2. How to check tension (While auto tensioner is operating:
and fixing pin being
1) After rotating crankshaft 2 revolutions clockwise to position
No.1 cylinder at
TDC wait for about 5 minutes, and measure the amount of
protruding of the auto
Caution: This is "leak down" time for the auto tensioner rod
to protrude 1mm
when tension caused by rotation of the crankshaft has
2) Check if the amount of rod protruding is in the range of
3.8 -4.5 mm.
3. Recheck if each sprocket is within the specified range.
Notice: ¡fit is not within the specified range, repeat from
