Subaru Legacy/Outback

1. Driving belts are located in 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 cost to the owner of the car a pretty penny.
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 by one belt more than one unit can be put in action.
3. Kill the engine, open a cowl and find driving belts. Highlighting itself a small lamp, fingers feel belts on all their length, checking for existence of cracks and stratifications. Also presence on a belt of attritions, zapolirovanny to gloss of sites and other obvious defects is inadmissible. Examine belts from both parties 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.

The assessment of effort of a tension of a belt can be made by a nazhimaniye on it by a thumb on a site in the middle between pulleys of the generator (belt A/K/V compressor (belt B) and a cranked shaft. Pressing has to be rather firm (with effort about 10 kgfs). The parameter characterizing effort of a tension of a belt is the size of its deflection at a nazhimaniye. Admissible range makes 7.0 ÷ 9.0 mm (a new belt) of/9.0 ÷ 10.0 mm (which was in the use a belt) for a belt A and 7.5 ÷ 8.5 mm (a new belt) of/9.0 ÷ 10.0 mm (which was in the use a belt) for a belt B (model with To/in).

Tension of a driving belt it is validated by finding of the index within the working range (D) indicator scale of an automatic natyazhitel.

1. 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 given by a belt. In this case it is the generator and/or an intermediate (tension) roller.
2. Usually it is the share of each of the driving belts used on the engine on one component which fixture is carried out by means of axial/lock and adjusting bolts. The axial/lock bolt is released, then the adjusting rotates in the relevant party.
3. For weakening 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 a tightening of bolts.
4. On some models for shift of hinged units it is necessary to use the lever, - observe extreme care, try not to damage units.
