Condition check, adjustment of a tension and replacement drive a belt (each 12 000 km (7500 miles) run, or times in 6 months)

Check

Приводной (or as it often name, V-shaped, or it is simple вентиляторный) the belt is located in a forward part of the engine and plays the important role in its maintenance and all auxiliary units of functioning. In view of character of use and the nature of a material from which it is made, the belt is exposed eventually to some physical changes and its condition, no less than tension adjustment, in order to avoid serious damages of the engine, should be checked and be corrected regularly.

On the given models of cars it is used unique приводной the belt of tape type actuating the generator, the pump of system of hydrostrengthening of a wheel and the compressor of the conditioner of air.

 PERFORMANCE ORDER

  1. At the switched off engine open a cowl and find приводной a belt which is in a forward part of the engine. By means of a small lamp carefully examine a belt on all length, checking it on presence of stratifications, cracks, branches of tapes from a sticky basis, ruptures and deterioration of tapes, cracks on internal edges of tapes and other damages and defects. The condition of a belt from its both parties that means necessity of a reversing of each of examined sites of a belt inside out should be checked up. Sites of a belt inaccessible to survey should are checked carefully up to the touch. In case of revealing of any of the defects set forth above the belt is subject to replacement (pass to the item "For belt replacement..." Or "For easing of a tension of a belt...").
  1. Presence of only small cross-section cracks on an inside of a V-shaped belt - is admissible at detection of longitudinal cracks or the separated slices which are a source of extraneous sounds at work of a belt, demands replacement of the last.

Adjustment

The tension drive a belt of 6-cylinder engines is checked by means of the special measuring instrument hooked for the middle of a direct site of a belt between a pulley of the pump of system of hydrostrengthening of a wheel and a tension roller. Compare instrument readings to requirements of Specifications in the beginning of the given Chapter.

If you have possibility to take advantage of a measuring instrument of effort of a tension of a belt of firms Nippondenso or Burroughs, in drawing is shown as to use each of them - compare indications of scales of devices to requirements of Specifications (only for 6-cylinder engines).

Adjustment of a tension of a belt is carried out by easing of an axial bolt of a pulley of the pump of system of hydrostrengthening of a wheel, a counternut and lock bolts, then it is necessary to turn an adjusting bolt counter-clockwise for easing of effort of a tension, or clockwise - for increase. Repeat procedure before reception of satisfactory result, then shade a counternut and bolts.

 PERFORMANCE ORDER

  1. On the models equipped with 6-cylinder engines ослабьте bolts of a pulley наоса of the hydraulic booster of a wheel also turn an adjusting bolt натяжителя in the corresponding party for increase or easing of effort of a tension of a belt.
  1. On the models equipped with engines V8 by effort of a tension of a belt operates подпружиненный натяжитель and necessity for regular adjustment of a tension is absent. If the arrow of the index on a back wall натяжителя is rejected from a control label on a casing натяжителя more than on 3,2 mm, it is necessary to replace a belt.
  1. Натяжитель a belt of the tape type, applied on engines V8 automatically supports effort of its tension, however, in the limited limits - the arrow of the index on a casing натяжителя () should not deviate further a point And on a casing.

Replacement

6-cylinder engines

For belt replacement make all procedures which are carried out by preparation for adjustment of its tension, however, in summary remove a belt from a pulley of a cranked shaft and take it from an impellent compartment. At installation of a new belt track correctness of its lining as its infringement can lead to rotation of a water wheel in the opposite direction. The scheme of a lining of a belt is resulted on шильде, fixed on a fan casing.

The typical scheme of a lining tape drive a belt of the 6-cylinder engine.

Engines V8

 PERFORMANCE ORDER

  1. For easing of a tension of a belt turn натяжитель by means of a face head on 3/8 inches (9,53 mm) clockwise. After easing of a tension of a belt натяжитель will deviate downwards. Remove a belt and cautiously release натяжитель. Put on a new belt pulleys, again having turned for this purpose натяжитель. Release натяжитель. Remember that infringement of correctness of a lining of a belt can lead to rotation of the water pump in the opposite direction that will cause a fast overheat of the engine. The lining scheme drive a belt is resulted on шильде, fixed on a fan casing.
  1. Loosen the effort of a tension of a belt, having turned натяжитель clockwise by means of the key which has been put on its bolt.
  1. The lining scheme drive a belt is resulted on шильде fixed on a casing of the fan or скобе a radiator.

All engines

 PERFORMANCE ORDER

  1. The removed old belt take with itself in shop for сравнивания with it new - belts should correspond each other on a design, length and width.
  2. At replacement drive a belt watch correctness of its installation in flutes of pulleys. Correctness of centering of a belt on pulleys is of great importance for reliability of its functioning.
  3. Adjust a tension of a new belt according to instructions of the above-stated points.
