Tooth belt tension, setting
Tooth belt tension, setting |
Note | ||
Set while the engine is cold - room temperature. |
For this procedure, the drive belt tension must have been checked first. This means the crankshaft is set to "No. 1 cylinder TDC" and camshaft gear fixed with KM-852 - see procedure Tooth belt tension, check .
1. |
Undo the tooth belt tensioning pulley retaining bolt (I).
|
3. |
Remove the blocking tool KM-852.
|
4. |
Turn the crankshaft twice (720°) in the direction of engine rotation using the tooth belt sprocket retaining bolt and position it to "ignition TDC for cylinder 1" (III). The markings on the camshaft sprockets must be in front of each other (II). Turn the crankshaft slowly and evenly.
|
5. |
Fix the camshaft sprocket with KM-852.
|
Adjusting new tooth belt |
1. |
Undo the bolt on the drive belt tensioning pulley slightly and turn the eccenter adjuster in the direction of the arrow (clockwise) until:
|
2. |
Tighten the tensioning pulley locking screw - tightening torque 20 Nm.
|
3. |
Remove the blocking tool KM-852.
|
4. |
Turn the crankshaft two more times (720°) in the direction of engine rotation, set it to "No. 1 cylinder TDC" and check the drive belt tension pulley setting.
|
5. |
If the tensioning pulley pointer does not agree with the corresponding mark, the procedure must be repeated.
|
