1.
caution |
- To reuse the drive belt, draw an arrow
indicating
the rotating direction on the back of
the drive belt using chalk to install
the same direction.
- Be careful not to get your fingers
caught.
|
Set special tool drive belt remover (MB992728)
between the A/C compressor drive
belt and the crankshaft pulley as shown.

|
3.The arrow on the special
tool should point in direction of travel. Then prise off the
A/C compressor drive belt. 4.Rotate the
crankshaft pulley clockwise further to remove the A/C
compressor
drive belt. 5.Check the crankshaft pulley groove
for dust or dirt. If it is contaminated, use an
air blower to clean.

|
1.Set the tool to the pulley
bolt of auto-tensioner, and then turn the auto-tensioner
clockwise. 2.
caution |
To reuse the drive belt, draw
an arrow indicating the rotating
direction (clockwise) on the back of the belt
using chalk, etc.
|

1.Use the following special
tools to hold the crankshaft pulley.
- Pulley holder (MB991800)
- Crank pulley holder (MB992100)
2.Loosen the crankshaft pulley bolt and remove
the crankshaft pulley washer and crankshaft
pulley.

|
3.If the crankshaft pulley
cannot be removed from the crankshaft, follow the procedure
below. (1)
Install the crankshaft pulley bolt and crankshaft pulley
washer to the crankshaft
pulley. At this time, the crankshaft pulley bolt must be
loosened by 3 to 4 turns from the completely
tightened state. (2)
Using the special tools below, remove the crankshaft
pulley.
- Crank pulley puller (MB992099)
- Crank pulley holder (MB992100)

1.Wipe the dirt on the
crankshaft pulley washer using a rag. 2.Using a
rag, wipe the dirt on the crankshaft pulley, the crankshaft
sprocket, the
thread hole of the crankshaft and then remove the
grease.
note |
Degreasing is necessary to
prevent decrease in the friction between
contacting surfaces.
|
3.Install the crankshaft
pulley. 4.Apply an appropriate and minimum amount
of engine oil to the threads of crankshaft
pulley bolt and lower part of the
flange. 5.Install the crankshaft pulley washer to
the crankshaft pulley bolt. 6.In the same way as
for removing, using the special tools below, support the
crankshaft
pulley.
- Pulley holder (MB991800)
- Crank pulley holder (MB992100)
7.Tighten the crankshaft pulley bolt according
to the procedure below. (1)
Tighten the crankshaft pulley bolt to the specified
torque. Tightening torque: 265
N·m (2)
Loosen the crankshaft pulley bolt fully. (3)
Tighten the crankshaft pulley bolt to the specified torque
again. Tightening torque: 275
N·m

|
2.Put special tool drive
belt installer (MB992992) on the crankshaft pulley, and then
hook
the A/C compressor drive belt onto the projection of
the special tool.
|

|
5.
caution |
- Be careful not to get your fingers
caught.
- Never turn the crankshaft
anti-clockwise.
|
Use a tool to rotate the crankshaft pulley
clockwise. While doing this, be careful that
