3.6. A gear belt with the automatic mechanism of a tension

Removal

PERFORMANCE ORDER
1. Operations on removal of a gear cм belt. subsection 3.5, but considering that the pulley of the mechanism of a tension has an automatic regulator.
2. Before removal of a gear belt weaken its tension for what unscrew a bolt of fastening of a pulley of the mechanism of a tension, then insert a big screw-driver or the lever into a groove on the lever of the mechanism of a tension and turn the lever before belt release. For deduction of the mechanism of a tension in this situation screw up a fastening bolt.

Installation

PERFORMANCE ORDER
1. Before installation of a gear belt check position of the water pump. Thus the ledge on a flange of the water pump should be combined with I correspond a shchy ledge on the block of cylinders. Otherwise weaken bolts of fastening of the pump and move it in a sootvetstvo yushchy situation, then tighten bolts of fastening the demanded moment.
2. Establish a gear belt (see subsection 3.5.2), then adjust its tension.

Adjustment

PERFORMANCE ORDER
1. Weaken a bolt of fastening of a pulley of the mechanism of a tension and move the mechanism lever so that the index was combined with an emphasis. For fixing of the mechanism of a tension in this situation screw up a fastening bolt.
2. Turn a cranked shaft of the engine on two complete revolutions in the direction of working rotation and check, that labels on a pulley of a cranked shaft and a camshaft were combined from the index ми. Weaken a bolt of fastening of the mechanism of a tension and turn the lever of the mechanism of a tension clockwise until the index will not be combined with cut in an arm of the mechanism of a tension. At installation of a new gear belt it some business hours will be earned extra. At installation of the belt which was in the use, establish the index approximately on 4 mm on the left from the groove center.
3. Tighten a bolt of fastening of the mechanism of a tension. Turn a cranked shaft of the engine on 1 complete revolution in the direction of working rotation and check that adjusting labels on pulleys of cranked and distributive shaft were combined with indexes. Establish on the engine all remained earlier removed details.
4. After carrying out adjustment of a tension of a gear belt in the course of operation of the engine the tension of a gear belt will be automatically supported.
