3.2.9. Pulleys of a gear belt, mechanism of a tension and single pulley

GENERAL INFORMATION

Pulley of a camshaft of engines 1,8 and 2,0 of l

Removal

PERFORMANCE ORDER
1. Remove a gear belt.
Pulleys of camshafts
2. For unscrewing of a bolt of fastening of a pulley of a camshaft fix a camshaft to a provorachivaniye or for a pulley of a camshaft or a wrench for camshaft grooves.
3. Unscrew a bolt and remove a pulley from the camshaft end. On engines of 1,6 l pulleys of inlet and final camshafts differ from each other. The pulley of the camshaft operating final valves, should be identified by ledges which make active the sensor of provision of a camshaft. On l models 1,8 and 2,0 both pulleys the identical.
Pulley of a cranked shaft of model of 1,6 l
4. Remove a pulley from the end of a cranked shaft.
Pulley of a cranked shaft of models 1,8 and 2,0 of l

Prevention

For fastening of a pulley of a cranked shaft it is necessary to use a new bolt.


5. Weaken a bolt of fastening of a pulley of a cranked shaft. To prevent a cranked shaft from a provorachivaniye, the assistant should include any transfer and press a brake.
6. Unscrew a bolt and remove a pulley from the end of a cranked shaft.
Mechanism of a tension of a gear belt
7. Unscrew bolts and remove the mechanism of a tension of a belt assembled from the engine.
Single pulley
8. Unscrew a bolt and remove a single pulley from the engine. On l models 1,8 and 2,0 if it is necessary, unscrew a bolt from a suspension bracket of fastening of a pulley or remove a pulley together with a suspension bracket.

Installation

PERFORMANCE ORDER
Pulleys of camshafts

Prevention

At installation of pulleys of camshafts it is necessary to use new bolts.


1. Before installation of pulleys check an oil sealing ring on wear and damage and, if necessary, replace.
2. Check that the adjusting pulley is in a camshaft nest.
3. On models of 1,6 l combine a groove on a pulley with an adjusting pin and fix a pulley a bolt.
4. On l models 1,8 and 2,0 in pulleys there are two grooves for an adjusting pin. If the pulley is established on a camshaft operating inlet valves, the adjusting pin settles down in a groove with IN inscription. And if the pulley is established on a camshaft operating final valves, the adjusting pin is established in a groove with EH inscription.
5. Correctly establish pulleys on camshafts and fix them bolts, having tightened the demanded moment. Thus fix a camshaft a wrench from a provorachivaniye.
6. Establish a gear belt and establish a cover of a head of the block of cylinders.
Pulley of a cranked shaft of model of 1,6 l
7. Establish a pulley on a cranked shaft. Thus the adjusting label should be combined with the index.
8. Establish a gear belt.
Pulley of a cranked shaft of models 1,8 and 2,0 of l
9. Establish a pulley of a cranked shaft. Thus the adjusting label should be combined with the index.
10. Fix a cranked shaft from a provorachivaniye and tighten a bolt of fastening of a pulley.
11. Establish a gear belt.
Mechanism of a tension of a gear belt
12. Establish the tension mechanism, thus a ledge on a basic plate should settle down in an opening of a casing of the oil pump. Previously screw up a bolt of fastening of the mechanism of a tension. Using a six-sided key, turn the lever of the mechanism of a tension clockwise against the stop and finally tighten a fastening bolt.
13. Establish a gear belt.
Single pulley
14. On models 1,8 and 2,0 of l establish a suspension bracket of a single pulley to the block of cylinders and fix bolts, having tightened them the demanded moment.
15. On all models establish a single pulley and fix a bolt, having tightened it the demanded moment.
16. Establish a gear belt.
