Removal and installation of a belt of drive ГРМ and its covers

The general information

The basic function of a gear belt is the drive of a camshaft from cranked. In parallel the belt is used also for a drive of the water pump of system of cooling of the engine. Проскальзывание or breakage газораспределительного a belt at the working engine can lead to serious internal damages of a head of cylinders as a result of contact of valves to the bottoms of pistons. Jamming of the water pump, wetting of a belt by the cooling liquid following through a faulty epiploon of the pump, and also strong deterioration or mechanical damage of a tape or belt teeths can become the reason of such troubles.

In view of told, extreme importance is got by a regularity of performance of checks of correctness of adjustment of effort of a tension of a belt and its general condition. Performance of the given checks becomes possible only after dismantle of covers of a belt.

Removal of internal section of a cover газораспределительного a belt is included in structure of procedure of replacement of an epiploon of a camshaft (the Section Replacement of an epiploon of a camshaft see).

REMOVAL

Covers of drive ГРМ with accompanying components

1 — the Top cover of a belt
2 — the Bolt of fastening of the top cover with a washer
3 — the Bottom cover of a belt
4 — Bolts of fastening of the bottom cover
5 — the Cogwheel of a cranked shaft

6 — the Pulley of a cranked shaft
7 — the Belt of a drive of auxiliary units
8 — the Bolt of a cogwheel of a cranked shaft
9 — the Bolt of a pulley of a cranked shaft


 PERFORMANCE ORDER

1. Before to start procedure performance it is necessary to make иммобилизацию the engine and the car:
a) Disconnect a negative wire from the battery.

If the stereosystem established on the car is equipped by the security device before to disconnect the battery make sure that have a correct code for audiosystem input in action.

b) Prop up wedges back wheels of the car and cock a lay brake. Control lever РКПП translate in neutral position;
c) Release bolts of fastening of the right forward wheel, then поддомкратьте redock of the car and establish it on props.
2. For the purpose of maintenance of the best access to covers remove an air cleaner and an air sleeve from a mudguard of an arch of a wheel and a final collector. Take probe measurements of impellent oil and clean it aside.
3. Hang out the engine with the help лебедки, or having propped up its hydraulic jack (for the purpose of loading distribution, between a head of a jack and the pallet картера it is necessary to lay wooden брусок).

4. In stages release and turn out two bolts of a support of the power unit, located directly under a pulley of a cranked shaft. Remove washers.

5. Slightly lower the engine, having provided free space for removal of a pulley of a cranked shaft.
6. Remove a belt of a drive of auxiliary units (see Has undressed Removal, installation and adjustment of effort of a tension of a belt of a drive of auxiliary units).
7. Keeping a pulley from проворачивания for the central bolt, turn out four fixing bolts. Remove a pulley.

For a guarantee of reliable blocking of a pulley in process отдавания bolts of its fastening include the higher transfer (do not forget to be switched again to a neutral after pulley removal) and ask the assistant to squeeze out a pedal of a foot brake firmly. It is possible to take advantage also of a rubber cord / old приводным a belt, densely having wrapped up it round a pulley.

8. Release two clamps, turn out a bolt (on models of last years of release - 2 bolts) and remove the top cover газораспределительного a belt.

9. Release a back clamp, turn out two bolts and remove the bottom cover of a belt. For the purpose of providing of access to a forward bolt on the models equipped with the hydraulic booster of a wheel or К/В, by means of the key put on the central bolt take away the party натяжитель auxiliary drive a belt, turning it clockwise. In case of need натяжитель can be removed completely for what it is necessary to give the central bolt, rotating it counter-clockwise and to remove it together with a washer.
10. Result the engine in position ВМТ (see Has undressed Reduction of the piston of the first cylinder in position of the top dead point (ВМТ) the end of a step of compression).
11. Check up a belt on presence of factory directional markers of rotation. In case of need put corresponding marks independently (if certainly the belt is in a satisfactory condition and is subject to the further use).

12. Give a counternut and, having allowed натяжителю to be developed clockwise, ослабьте a belt.

13. Without supposing проворачивания shaft, remove a belt from cogwheels. Try not to overwind a belt and excessively not to bend it.

14. Check up a belt on presence of traces of pollution by a cooling liquid or oil. In case of detection of those, try to reveal immediately a source of leak and to eliminate its reason. It is necessary to give special attention to a condition of leading edges of teeths of the working party of a belt. The worn out, polluted or defective belt is subject to replacement.

Through each 50 000 km (30 000 miles) run the belt should be changed without dependence from its condition.

15. If the belt back not is established at once, on the engine it is necessary to hang the precautionary tablet on purpose not to admit casual проворачивания its shaft. For a guarantee it is possible to seal up just in case the ignition lock.

INSTALLATION

 PERFORMANCE ORDER

1. Check up correctness of combination of adjusting labels of cogwheels of both shaft (see Has undressed Reduction of the piston of the first cylinder in position of the top dead point (ВМТ) the end of a step of compression).

2. Put on a belt a cogwheel at first a cranked shaft, then the water pump and, in summary - a camshaft. Track observance of a demanded direction of rotation of a belt.

3. Without supposing перекручивания, get a belt the smooth party under a roller натяжителя. Track, that the forward part of a belt has appeared hardly tense, and all weak point had on a site got under a roller натяжителя.

4. Slightly tighten a counternut, then inserted into an adjusting aperture прутковым a key develop эксцентриковую assemblage натяжителя clockwise, choosing a belt weak point.

5. Continue to develop натяжитель until the sliding index will not be combined with sample in a plate of the basis of assemblage. Tighten a counternut.

6. By means of a face key turn a cranked shaft on two complete revolutions for a cogwheel bolt, again having stopped it in position ВМТ of the end of a step of compression of the piston of the first cylinder. Make sure of correctness of combination of adjusting labels (see Has undressed Reduction of the piston of the first cylinder in position of the top dead point (ВМТ) the end of a step of compression). Once again check up correctness of installation of the sliding index натяжителя, in case of need repeat adjustment.
7. Check up serviceability of functioning натяжителя (see Has undressed Removal, check of a condition and installation of cogwheels and натяжителя a belt of drive ГРМ).
8. Establish into place the bottom and top sections of an external cover газораспределительного a belt. Latch clamps and strongly tighten fixing bolts.

Bolts of fastening to the bottom cover are subject to replacement without fail.

9. Establish a pulley of a belt of a drive of auxiliary units on a cogwheel of a cranked shaft, having tracked, that the small aperture of a pulley has got on a lug on a face surface of a cogwheel. Screw fixing bolts and tighten them with demanded effort (block a pulley from проворачивания).

10. Establish into place a belt of a drive of auxiliary units (see Has undressed Removal, installation and adjustment of effort of a tension of a belt of a drive of auxiliary units).
11. Raise the engine, having provided possibility of connection of the right support of a suspension bracket of the power unit.
12. Tighten bolts of fastening of the right support with demanded effort. Clean a jack/disconnect an elevating rigging.
13. Connect a sleeve of giving of the warmed-up air to a casing of a final collector and an air cleaner. Return in a working condition of system of ignition and a food.
14. Connect a negative wire to the battery.
15. In summary check up correctness of installation of a corner of an advancing of ignition (the engine Electric equipment see the Head).
