Removal

PERFORMANCE ORDER

1. Ослабьте a bolt of fastening of a pulley of the water pump. 2. Ослабьте a bolt of fastening of the generator. 3. Remove a pulley of the water pump and a belt. 4. Remove a pulley of a cranked shaft. 5. Remove a casing of a gear belt. 6. Move a roller of a tension of a gear belt to the water pump and temporarily fix it in this position. 7. Turn out a bolt of fastening of a pulley of a camshaft. 8. Remove a camshaft pulley. 9. Remove a gear belt. The prevention Note a direction of rotation of a gear belt for its repeated installation in initial position. 10. Turn out a bolt of fastening of a pulley of a cranked shaft. Remove a pulley of a cranked shaft and the plug. 11. Remove a roller of the mechanism of a tension of a gear belt.

Check

The prevention

Strongly do not bend a gear belt and do not change a direction of its rotation. Do not allow oil and lubricant to contact with a gear belt as it will lead to its destruction.

PERFORMANCE ORDER

1. Check up a gear belt on absence of damages, deterioration, stratification, cracks on teeths and in the basis of teeths, and also on defects at end faces and a belt underside. 2. In the presence of following defects replace a gear belt.

The description	Defect
1. The rigid return surface gear ремняПоверхность has a glossy appearance. Rigidity of a surface is that that the nail does not leave traces on a belt
2. Cracks on a return surface of a gear belt
3. Cracks or stratification of a gear belt
4. Strongly worn out зубьяИзношена the tooth party, fibres, a cord and the rubber basis become thus visible
5. Teeths (last stage) are worn strongly out the tooth party Is worn out, attritions become thus visible and the thickness of a tooth is reduced
6. Cracks in the basis of teeths
7. Absence of a tooth
8. Strong deterioration of one party of a belt
9. Cracks on a lateral face of a gear belt

Pulleys and roller of the mechanism of a tension of a gear belt

PERFORMANCE ORDER

1. Check up pulleys of distributive and cranked shaft, a roller of the mechanism of a tension and a single pulley on absence of non-uniform deterioration, cracks and damages. 2. Check up ease and smoothness of rotation of a roller of the mechanism of a tension and a single pulley, and also absence of extraneous noise at rotation.

Installation of the mechanism of a tension of a gear belt

PERFORMANCE ORDER

1. Temporarily fix the mechanism of a tension of a gear belt in the taken away position as it is possible more close to the water pump. 2. After installation of the mechanism of a tension adjusting labels on pulleys of distributive and cranked shaft should be combined with indexes. Turn a cranked shaft of the engine so that the piston of the first cylinder was established in ВМТ in a compression step.

PERFORMANCE ORDER

The prevention Be convinced that the plug is established correctly, thus the facet should be from the forward party of the engine. 1. At installation of a pulley of a camshaft the adjusting pin should enter into a pulley aperture. 2. Establish a gear belt so that to exclude its sagging from outside tension.

Installation

PERFORMANCE ORDER

1. Establish the plug and a pulley of a cranked shaft as is shown in drawing. Pay attention to a direction of their installation. The inhaling moment: 140–150 Н•м 2. Establish a pulley of a camshaft and fix a bolt, having tightened its demanded moment. The inhaling moment: 80–100 Н•м 3. Combine adjusting labels on pulleys of distributive and cranked shaft with indexes, thus the piston of the first cylinder should be established in ВМТ in a compression step. 4. At installation of the mechanism of a tension of a gear belt first of all establish the tension mechanism, a spring and распорную the plug. Temporarily tighten bolts. Then, temporarily compress the tension mechanism, having inserted a bolt into the extended aperture. Establish the back end of a flat spring opposite to a forward cover, as is shown in drawing. 5. Fix the mechanism of the tension which have been taken away to the water pump. 6. Establish a gear belt on a pulley of a cranked shaft. 7. Establish a gear belt on a camshaft pulley, be thus convinced that its sagging from outside tension is excluded. 8. Ослабьте bolts of 1 and 2 fastenings of the mechanism of a tension in the sequence shown in drawing, the spring of the mechanism of a tension of a gear belt thus will be unclenched. 9. Tighten bolts of 1 and 2 fastenings of the mechanism of a tension in the same order. 10. Turn clockwise a cranked shaft of the engine on two complete revolutions and combine a label on a pulley of a gear belt of a cranked shaft with the index on the block of cylinders of the engine. Check up that a label on a camshaft pulley were combined with the index on a cover of a head of cylinders. The prevention Do not turn a cranked shaft of the engine counter-clockwise. 11. In the same order ослабьте bolts of 1 and 2 fastenings of the mechanism of a tension of a gear belt. 12. Tighten bolts of 1 and 2 fastenings of the mechanism of a tension in the same order. The inhaling moment: 20–27 Н•м 13. Repeatedly check up a tension of a gear belt. By pressing the tense branch of a gear belt with effort 49 Н the gear belt should cave in to the centre of a head of a bolt of fastening of the mechanism of a tension. 14. Establish casings of a gear belt. The inhaling moment: 10–12 Н•м 15. Establish a pulley of a cranked shaft. 16. Establish поликлиновой a belt of a drive of the fan and adjust its tension. 17. Establish a pulley of the water pump. 18. Establish поликлиновой a belt and adjust its tension.
