1.Loosen the nut for alternator pivot bolt and alternator fixing nut.
2.
| caution |
To reuse the drive belt, draw an arrow indicating the rotating
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.
|
|
|
Use the used drive belt to fix the crankshaft damper pulley in the following procedures,
and remove the crankshaft pulley centre bolt.
|
|
1.
| caution |
- Do not use the drive belt set up on the vehicles.
- Do not use a cracked or damaged drive belt.
|
Set the used drive belt as shown and hold it with a cable band.
|
|
2.
| caution |
Do not hang the used drive belt for the crankshaft rotation stopper
on the water pump pulley.
|
Turning the crankshaft damper pulley to the anti-clockwise direction (to the left), loop
the used drive belt around the water pump body.
3.Hold the crankshaft damper pulley and remove the crankshaft pulley centre bolt.
|
|
1.Wipe off the dirt on the crankshaft and the crankshaft damper pulley as shown in the figure
using a rag.
2.After wiping off the dirt on the crankshaft and crankshaft damper pulley as shown
in the figure using a rag, degrease the areas.
| note |
Degrease them to prevent drop in the friction coefficient of the pressed area which is
caused by oil adhesion.
|
3.Install the crankshaft damper pulley.
4.Wipe off the dirt on the crankshaft pulley washer and the crankshaft pulley centre
bolt as shown in the figure using a rag.
5.Apply an adequate and minimum amount of engine oil to the thread
of the crankshaft pulley centre bolt and the lower area of the flange.
|
|
6.
| caution |
- Do not use the drive belt set up on the vehicles.
- Do not use a cracked or damaged drive belt.
|
Set the used drive belt and hold it with a cable band as during removal.
|
|
7.
| caution |
Do not hang the used drive belt for the crankshaft rotation stopper
on the water pump pulley.
|
Turning the crankshaft damper pulley to the clockwise direction (to the right), loop the
used drive belt around the water pump body.
8.Hold the crankshaft damper pulley and tighten the crankshaft pulley centre bolt to
the specified torque.
Tightening torque: 50 N·m
|
|
9.As shown in figure A, put a paint mark on one angle of the crankshaft pulley centre bolt.
Then, put a paint mark on the crankshaft damper pulley on the extended line of the angle next
to the marked angle.
10.
| 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 centre bolt in a 60 degree angle, and check that the paint
mark on the crankshaft pulley centre bolt aligns with the paint mark on the crankshaft damper
pulley as shown in figure B.
11.Loosen the crankshaft pulley centre bolt fully.
12.Hold the crankshaft damper pulley and tighten the crankshaft pulley centre bolt to
the specified torque.
Tightening torque: 50 N·m
|
|
13.As shown in figure A, put a paint mark on one angle of the crankshaft pulley centre bolt.
Then, put a paint mark on the crankshaft damper pulley on the extended line of the angle next
to the marked angle.
14.
| 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 centre bolt in a 60 degree angle, and check that the paint
mark on the crankshaft pulley centre bolt aligns with the paint mark on the crankshaft damper
pulley as shown in figure 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.
|
|
|
Install the drive belt to each pulley as shown in the figure.
