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

|
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.
|

|
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
