1.Loosen the idler pulley
nut. 2.
caution |
To reuse the drive belt, draw

direction (clockwise) on the back of the belt
using chalk, etc.
|
Turn the adjusting bolt in the anti-clockwise
direction (to the left) to remove the drive
belt.

1.Wipe off the dirt on the
oil pump drive shaft, crankshaft and crankshaft pulley as
shown
in the figure using a rag, and then degrease the
areas.
note |
Degrease them to prevent drop
in the friction coefficient of the pressed area,
which is
caused by oil adhesion.
|
2.Apply a small amount of engine oil to the
entire inner diameter of the crankshaft
front oil seal lip. 3.Install the crankshaft
pulley. 4.Wipe off the dirt on the crankshaft
pulley washer and the crankshaft pulley bolt as
shown in the figure using a rag. 5.Apply an
adequate and minimum amount of engine oil to the threads
of the crankshaft pulley bolt and the lower area of the
flange. 6.Use the following special tools as
during removal to support the crankshaft
pulley.
- Front hub and flange yoke holder (MB990767)
- Pin (MD998719)

7.Tighten the crankshaft
pulley bolt according to the following procedure. (1)
Tighten the crankshaft pulley bolt to the specified
torque. Tightening torque: 250
N·m (2)
Loosen the crankshaft pulley bolt fully. (3)
Tighten the crankshaft pulley bolt to the specified torque
again. Tightening torque: 110
N·m (4)
As shown in the illustration "A," apply the paint mark to
the crankshaft pulley on the
extended line of the corner adjacent to the one of the
crankshaft pulley bolt corners. (5)
|
caution |
- When the tightening angle is
smaller than
the specified tightening
angle, the appropriate
tightening capacity cannot
be secured.
- When the tightening angle is
larger than the specified
tightening angle, remove
the bolt to start from the
beginning again according to
the procedure.
|
|
Tighten the crankshaft pulley bolt by 60° once
more. Make sure the paint mark
of crankshaft pulley bolt is aligned with the paint mark of
crankshaft pulley as shown in the
illustration "B."

|
caution |
- To reuse the drive belt, install it by
aligning
the arrow mark on the backside of belt
marked at the removal with the rotating
direction.
- Check that the notches of notched pulley
and notches of drive belt are fit
correctly.
- Check that the drive belt is installed
in the centre of flat surface of flat
pulley.
