Adjusting the tension of the toothed belt (engine 2.0 l

Rotate the crankshaft in the position of top dead center (TDC) of cylinder number 1 (ignition) in the direction of rotation of the engine (tag 2) (Figure 2.70). To do this, rotate the crankshaft attachment bolt for the drive gears. Notches on the camshaft sprocket should be aligned with marks on the lid of the cylinder head.

NOTE Locking device KM-853 should be installed in this position. Adjust the synchronization of the timing mechanism, if necessary

Installation components

Attach the top of the cover toothed belt to the back cover of the toothed belt and tighten the moment of 6 Nm Replace the air filter housing with the sensor mass air flow. Connect the wiring harness connector sensor mass air flow. Connect a massive wire to the battery.

NOTE Adjustment is performed on a cold start at room temperature. Before adjustment necessary to check the tension of a toothed belt. This means that the crankshaft is set to TDC of cylinder number 1 and the star camshaft locked device KM 853.

Adjustment

Fig. 2.71. Adjusting the tension of

the toothed belt

Loosen the bolt mounting tension pulley toothed belt I (Figure 2.71). Turn toothed belt tension roller eccentric control in the direction of the arrow (counterclockwise).

NOTE Index tension pulley toothed belt should be just right before the constraint I (Fig. 2.71).

Tighten the attachment bolt tension pulley toothed belt Remove the device KM 853. Rotate the crankshaft two turns (720 °) in the direction of rotation of the engine in the position of top dead center (TDC) of cylinder number 1 mark III (Figure 2.71). Turn the screw for mounting drive gears.

NOTE Rotate the crankshaft slowly and smoothly.

Notches on the camshaft sprocket should be aligned with the tag II on the cover of the cylinder head (Figure 2.71). Block stars camshaft in position by a KM-853. Partially loosen the attachment bolt tension pulley toothed belt and turn the adjusting eccentric in the direction of the arrow (clockwise). Option I: pointer tension pulley toothed belt combined label.

Fig. 2.72. Adjusting the tension of

toothed belt tension pulley on a pointer: 1 - pointer tension pulley, 2 - Tag

Option II: Index tension pulley toothed belt combined with the label «NEW» (Figure 2.72). Tighten the attachment bolt tension pulley toothed belt moment 20 Nm Remove the device KM 853.

Check after adjustment

Rotate the crankshaft by two turns (720 °) in the direction of rotation of the engine in TDC position of the first cylinder and check the adjustment of tension pulley toothed belt. If the pointer tension pulley toothed belt is not combined with the label, repeat the process of adjustment.

Readjusted

Обкатайте timing belt and adjust it. Partially loosen the attachment bolt tension pulley toothed belt and turn the adjusting eccentric in the direction of the arrow (clockwise). Option I: pointer tension pulley toothed belt is located approximately 4 mm to the left of the tag.
