THE GENERAL DATA

The prevention
Replacement of a gear belt is necessary for making on the cold engine.
Removal

PERFORMANCE ORDER

1. Establish the piston of the first cylinder in the top dead point in a compression step. Bolts fix pulleys of a camshaft and the fuel pump.

2. Remove a pulley of a cranked shaft.

3. Unscrew bolts and remove the bottom casing of a gear belt together with rubber consolidation.

4. Loosen the bolts of fastening of the mechanism of a tension of a gear belt also disconnect a spring of the mechanism of a tension from adjusting pins.

5. Remove a gear belt. If the gear belt is repeatedly established, note a direction of its rotation

6. Check up a condition of a gear belt on deterioration, stratification or pollution by oil. In a case if the belt is polluted by oil, it is necessary to find a place of leak of oil and to eliminate it.

Installation

PERFORMANCE ORDER

1. Clear pulleys of a gear belt. Check up that pulleys of a camshaft and the fuel pump are fixed by bolts. Temporarily establish a pulley of a cranked shaft to a gear pulley and check up that the label on a pulley is combined with the index on the case of the oil pump. Also the label on a gear pulley of a cranked shaft should be combined with the index on the case of the oil pump (the label is specified by an arrow).

2. Remove an auxiliary pulley of a cranked shaft and establish a gear belt on pulleys of a cranked shaft, the oil pump, the fuel pump, a pulley of a camshaft and check up, that the back branch of a belt has been hardly tense. Check up that adjusting labels of pulleys are combined with indexes.

3. Pull a gear belt a spring of a pulley of the mechanism of a tension.

4. Check up that the adjusting label of a pulley of a cranked shaft is combined with the index then unscrew tightening bolts from pulleys of the fuel pump and a camshaft pulley.

5. Loosen the a bolt of fastening of a pulley of the mechanism of a tension also turn a pulley of a cranked shaft in the opposite direction on 60 ° (counter-clockwise).

6. Automatically to adjust a tension of a gear belt, fix a pulley of a cranked shaft from проворачивания and tighten a bolt of fastening of a pulley of the mechanism of a tension.

7. Turn a cranked shaft on two complete revolutions and check up that all adjusting labels on pulleys were combined with the index.

8. Loosen the a bolt of fastening of a pulley of the mechanism of a tension also turn a cranked shaft on 60 ° counter-clockwise to adjust a tension of a gear belt. Fix a pulley of a cranked shaft from проворачивания and tighten a bolt of fastening of the mechanism of a tension.

9. Establish a cranked shaft of the engine in position at which the piston of the first cylinder is in the top dead point in a step of compression and check up that all adjusting labels on pulleys were combined with indexes.

10. Establish casings of a gear belt and a pulley of a cranked shaft.
