If the auto-tensioner rod is fully
extended, reset it as follows:
|
![](../../../img/11/AK300154AA00ENG.png)
|
1.Clamp the auto-tensioner
in a vise with soft jaws.
|
![](../../../img/11/AK301074AD00ENG.png)
|
2.Push in the rod little by
little with the vise until the set hole A in the rod is
aligned
with hole B in the cylinder. 3.Insert a wire (1.4
mm in diameter) into the set holes. This auto-tensioner
setting
wire will be used during timing belt
alignment. 4.Unclamp the auto-tensioner from the
vise.
|
![](../../../img/11/AK301832AA00ENG.png)
|
5.
caution |
Leave the wire installed in
the auto-tensioner.
|
Install the auto-tensioner onto the front case and
tighten to the specified torque. Tightening
torque: 23 ± 3 N·m
|
![](../../../img/11/AK300147AD00ENG.png)
|
Set the tensioner pulley so that
the holes for attaching a wrench may be positioned as
shown in the illustration.
|
![](../../../img/11/AK300148AD00ENG.png)
|
1.Align the timing mark on
the camshaft sprocket with the timing mark on the rocker
cover.
|
![](../../../img/11/AK300149AD00ENG.png)
|
2.Align the timing mark on
the crankshaft sprocket with the timing mark on the front
case.
|
![](../../../img/11/AK301076AD00ENG.png)
|
3.Align the timing mark on
oil pump sprocket with its mating mark.
|
![](../../../img/11/AK301077AD00ENG.png)
|
4.Remove the plug on the
cylinder block and insert a Phillips head screwdriver (shank
diameter
8 mm) through the hole. If it can be inserted as deep as
60 mm or more, the timing marks are correctly aligned. If
the inserted depth is only 20 to 25 mm, turn the oil pump
sprocket one turn and realign
the timing marks. Then check to ensure that the screwdriver
can be inserted 60 mm or more. Keep
the screwdriver inserted until the timing belt is completely
installed.
|
![](../../../img/11/AK300151AD00ENG.png)
|
5.Set the special tool Set
screw (MD998738) as shown and screw it in up to the position
where the wire inserted in the auto-tensioner when
installing it can be moved lightly. 6.Install the
timing belt on the crankshaft sprocket, oil pump sprocket,
idler pulley,
camshaft sprocket, and tensioner pulley in that
order.
|
![](../../../img/11/AK301295AD00ENG.png)
|
7.Lift up the tensioner
pulley in the direction of the arrow and tighten the center
bolt. 8.Check that all timing marks are
aligned. 9.Remove the screwdriver inserted in step
5 and install the plug. 10.Turn the crankshaft a
quarter turn counterclockwise. Then, turn it clockwise until
the timing marks are aligned again.
|
![](../../../img/11/AK300150AD00ENG.png)
|
11.Install special tool
Tension pulley socket wrench (MD998767), socket wrench and
torque
wrench, onto the tensioner pulley, and loosen the tensioner
pulley center bolt.
note |
Use a torque wrench that can
measure 0 to 5.0 N·m.
|
12.Torque to 3.5 N·m with the torque
wrench. 13.Holding the tensioner pulley with
special tool Tension pulley socket wrench (MD998767)
and torque wrench, tighten the center bolt to
specification. Tightening torque: 48 ± 5
N·m
|
![](../../../img/11/AK301836AA00ENG.png)
|
14. The wire inserted at the
auto-tensioner installation is pulled out and then the
special
tool Set screw (MD998738) is removed by
hand. 15.Give two clockwise turns to the
crankshaft. Wait for 15 minutes, then proceed with
the following inspection steps.
|
![](../../../img/11/AK300152AA00ENG.png)
|
16.Check to see whether the
metal wire (inserted when the auto-tensioner was installed)
can
be removed without any resistance. If the metal wire can be
removed without any resistance,
it means that the belt has a proper tension. Therefore,
remove the metal wire. In this condition,
check that the rod protrusion of the auto-tensioner is
within the standard value. Standard value: 3.8
- 4.5 mm 17.If the metal wire
offers resistance when removed, repeat the previous steps 10
through
15 until the standard value is obtained as measured by the
rod projection of the auto-tensioner
rod.
