3.24. Check of a state, adjustment of effort of a tension and replacement of driving belts

Check

 PERFORMANCE ORDER

1. Driving belts are located in a forward part of the power unit and play an important role in functioning of the engine and many other systems of the car. Eventually belts wear out and have to look round regularly according to the schedule of routine maintenance of the car in order to avoid serious engine failures which correction of consequences can rise to the owner of the car in kopek.
2. The quantity of the driving belts used on concrete model of the car depends on a vehicle complete set auxiliary units. Belts are used for the drive of the generator, steering and water pumps, and also the air conditioner compressor. Depending on character of an arrangement of pulleys more than one unit can be put by one belt in action.

3. Kill the engine, open a cowl and find driving belts.

4. Highlighting itself a small lamp, fingers feel belts on all their length, checking for existence of cracks and stratifications. Inadmissibly also presence on a belt of attritions, zapolirovanny to gloss of sites and other obvious defects. Examine belts on both sides for what overwind them. Defective belts are subject to replacement without fail. Check a condition of edges on the lower party of belts, - they have to have identical depth in the absence of deformation signs.

5. Assessment of effort of a tension of a belt can be made by a nazhimaniye on it by a thumb on the site in the middle between two next pulleys. Pressing has to be rather firm. The parameter characterizing effort of a tension of a belt is the size of its deflection at a nazhimaniye. As a rule, if pulleys defend from each other at distance from 180 to 280 mm, the size of a deflection has to make 6.4 mm, to distance between pulleys in 305 ÷ 405 mm there corresponds the deflection in 12.5 mm - for a wedge-shaped belt, and 6.4 mm - for rill.


Adjustment

 PERFORMANCE ORDER

1. The tension of a driving belt with excessive effort can lead to premature failure of shkivny bearings of the corresponding units whereas, on the other hand, too weak tension results in bystry wear actually of a belt. Regularly check efforts of a tension of belts of the drive of all auxiliary units installed on the car.
2. As a rule, correction of effort of a tension of a belt (easing/strengthening) is carried out by shift in the relevant party of the hinged auxiliary unit / assembly of a natyazhitel given by a belt.
3. Usually about one component which fixture is carried out by means of axial/lock and adjusting bolts is the share of each of the driving belts used on the engine. The axial/lock bolt is released, then adjusting rotates in the relevant party.
4. For easing of effort of a tension of a belt the component should be displaced towards the engine and vice versa. Having finished adjustment, track reliability of tightening of bolts. For the shift of some hinged units it is necessary to use the lever, - observe extreme care, try not to damage the given device.

5. Throw with a new belt the corresponding pulleys.
6. Having wrung out pump assembly from the engine, achieve the required effort of a tension of a belt (see above).
7. Strongly tighten adjusting bolts, then - the fixing bolt on the back party of a basic arm of the pump.
8. Establish into place a generating belt (see above).


Belt of the drive of the K/V compressor

 PERFORMANCE ORDER

1. Weaken a pulley of a natyazhitel and take off a belt of the drive of the K/V compressor from the engine.
2. Installation is made upside-down.

Belt of the drive of the generator and K/V compressor

 PERFORMANCE ORDER

1. The scheme of laying of belts of the drive of auxiliary units on these models is submitted on illustrations (see above).
2. The car also establish to Poddomkratta it on props. At the corresponding complete set remove elements of protection of a case.
3. Release the fixing nut of a pulley of a natyazhitel and, rotating an adjusting bolt, weaken effort of a tension of a belt.
4. Throw off a belt from pulleys and take off it from the engine.
5. Put on a new belt pulleys of a bent shaft, the generator and (at the corresponding complete set) the K/V compressor and bring him under tension and intermediate rollers.
6. Rotating an adjusting bolt of a natyazhitel, achieve the required effort of a tension of a belt (see above).
7. Strongly tighten the fixing nut.
8. If removed, establish into place elements of protection of a case and lower the car on the earth.


Belt of the drive of the steering pump

 PERFORMANCE ORDER

1. Disconnect a negative wire from the battery and before starting implementation of the procedure, wait not less than 90 seconds for the purpose of deactivation of safety cushions.

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

2. The car also establish to Poddomkratta it on props. Remove elements of protection of a case.
3. Take off a belt of the drive of the К/В generator/compressor.
4. Lower the car on the earth and remove assembly of connecting draft of the pump of a control system of the speed (tempostat).
5. Pass a hose of system of hydrostrengthening of a wheel under the oil tank.
6. Release the fixing bolts of a pulley of a natyazhitel, then take off a belt of the drive of the steering pump from the engine.
7. Throw with a new belt the corresponding pulleys.
8. Pass a collar of strengthening of the drive of a face key (or other suitable tool) in an opening in an end face of an arm of a pulley of a natyazhitel and, having wrung out assembly of the last, achieve the required effort of a tension of a belt (see above).
9. Tighten the fixing bolts.
10. The car also establish to Poddomkratta it on props. Establish into place a belt of the drive of the К/В generator/compressor.
