Removal, check of a condition and installation of cogwheels and belt of a drive of balancing shaft

At the increase of a noise background connected with functioning of a belt of a drive of balancing shaft, first of all always it is necessary to make adjustment of its tension. This procedure can be made without removal of covers of a drive of GRM. Correction of effort of a tension of a considered belt is made by a natyazhitel of a gas-distributing belt.

REMOVAL

 PERFORMANCE ORDER

1. Bring the piston of the right cylinder into the provision VMT of the end of a step of compression (see. The section Reduction of the piston of the first cylinder in the provision of the top dead point (VMT)). Disconnect a negative wire from the battery.

If the stereosystem established on the car is equipped with a security code before disconnecting the battery make sure that have the correct combination for audiosystem input in action!

2. Remove a belt of a drive of the steering pump. Disconnect the pump from a basic arm (see. Head the Suspension bracket and a steering) also displace it aside.
3. Remove from a cover of a gas-distributing belt the generator with arms (see. Head engine Electric equipment).
4. To Poddomkratta the car also establish it on props. Remove protection of a case (see. Head the Body) and a cover in an arch of the left wheel.

5. Holding a pulley of a cranked shaft from a provorachivaniye a chain key, give a bolt of its fastening. Remove a pulley, having in case of need used a stripper.

6. Prop up the power unit a jack, for distribution of loading having laid wooden whetstone between a head of the last and the case pallet. Remove a pillow of the left support of the power unit with the arm (see. Section Check of a condition and replacement of support of a suspension bracket of the power unit).
7. Remove from the engine block щуп measurements of level of engine oil and its directing tube.
8. Turn out bolts of fastening of covers of a gas-distributing belt to the block. Make for itself the scheme explaining an order of an arrangement of various fixture on length which at assembly should be rolled strictly in former openings.

9. Remove the top and bottom covers of a belt of a drive of GRM.
10. Enter into a special opening in a back wall of the block of the engine a bolt or a prutkovy key in the x100 size 6 of mm (the opening is muffled by a bolt which should be turned out previously) which will block a back balancing shaft from a provorachivaniye in the course of removal of a driving belt.

The bolt/key should not be entered into an opening more deeply than on 74 mm (put the corresponding label)!

Detailed information on removal of a balancing shaft contains in the Section Removal and check of a condition of balancing shaft (4-cylinder engines).

11. Temporarily screw one of bolts of fastening of a cover of a gas-distributing belt in an opening of the left part of the lever of a regulator of a tension of a gas-distributing belt, tighten a bolt for the purpose of regulator blocking during weakening of a nut of a natyazhitel. Weaken a nut of a natyazhitel and wring out his roller from a belt of a drive of balancing shaft, having weakened thereby a tension of the last. Remove a belt.

If the belt is not replaced, mark its initial direction of rotation which should be surely observed at installation.

12. If cogwheels of balancing shaft (forward and back) are damaged, turn out bolts of their fastening. Blocking of a back shaft is already provided at the expense of introduction of a suitable bolt/core in an access opening from the back party of the block of the engine, fixing of a forward shaft can be carried out by a way of a prodevaniye to a service opening in its end face (directly under a cogwheel) a suitable screw-driver. Also remove a cogwheel of a cranked shaft.

The back balancing shaft is equipped with a set of the gear wheels which situation before removal is necessary accurately having marked in order to avoid mistakes at assembly.

CHECK

 PERFORMANCE ORDER

Carefully check a driving belt and cogwheels of balancing shaft on existence of signs of wear, cracks and other mechanical damages. Replace defective components.

INSTALLATION

 PERFORMANCE ORDER

1. Estimate a condition of a forward epiploon of a cranked shaft, in case of need make its replacement (see. Section Replacement of a forward epiploon of a cranked shaft). Put on a cogwheel a forward pin of a cranked shaft, - track combination of a landing shponka on a pin with a shponochny groove in a wheel nave.
groove in a wheel nave.
2. Before installation of a belt of a drive of balancing shaft and its cogwheels make sure of correctness of installation of a gas-distributing belt (see. Section Removal, check of a condition and installation of a gas-distributing belt and cogwheels of a drive of GRM). Make sure also that the piston of the first cylinder remains in the provision VMT of the end of the step of compression (see. The section Reduction of the piston of the first cylinder in the provision of the top dead point (VMT)). Both balancing shaft and the oil pump should be on the regular places, and the back shaft - is blocked entered into an opening of access by a bolt / прутковым a key. Take away a natyazhitel of a driving belt and fix it in new situation, operating in an order described in paragraph 11.

3. If removed, plant on balancing shaft the cogwheels. Make sure of correctness of combination of both sets of adjusting labels of a forward balancing shaft. Correctness of installation of a back balancing shaft is guaranteed automatically in view of existence of a directing pin (or a bolt), entering into a special service opening. Throw cogwheels with a driving belt.

4. Once again make sure of correctness of provision of adjusting labels, then screw bolts of fastening of cogwheels and tighten them with demanded effort.

5. Now it is possible to pass to adjustment of a tension of a belt. Make sure that the adjusting nut of a natyazhitel is released, then turn a cranked shaft so that the cogwheel of a camshaft was developed approximately on three teeth, - completely the weak point of both belts thus should get out. Tighten a nut of a natyazhitel with demanded effort.

For check of correctness of a tension of a belt firmly press on it a thumb near a camshaft cogwheel, - the belt should be densely tense from both parties of a wheel.
There is a possibility of adjustment of a tension of a gas-distributing belt and a belt of a drive of balancing shaft without removal of covers of a drive of GRM. However, it is more reasonable to remove nevertheless covers to have possibility of check of correctness of combination of adjusting labels.

6. If it was made removal/replacement only a belt of a drive of balancing shaft, turn out a bolt used for fixing of a regulator. Establish to the place of a cover of a gas-distributing belt and tighten with demanded effort fixing bolts. Track, that edges of sealing laying did not stick out from under edges on joints of forward covers.

7. At installation of a pulley of a cranked shaft do not forget to grease a carving and the bottom surface of a head of a bolt of its fastening. Screw a bolt and tighten it with demanded effort.
