Toyota RAV4>> Maintenance>> Check, adjustment of a tension and replacement of a poliklinovy belt of the drive of hinged units>> Check of a tension of a belt
The drive of the generator, the pump of the hydraulic booster of steering and the compressor of the conditioner is carried out by poliklinovy belts.
On models till 2001 one belt for the drive of the generator and the second belt for the drive of the compressor of the conditioner and the pump of the amplifier of steering is used, and on models since 2001 one belt of bigger length is used.
Install the gear shifting lever in neutral situation.
Apply with chalk a tag on a belt.
For a bolt of fastening of a pulley turn a bent shaft clockwise before emergence of a tag, at the same time visually check a condition of a belt.
On a poliklinovy belt the following defects can be found:
– traces of oil and lubricant;
– wear of edges of maple ledges;
– hardening of edges of maple ledges;
– cross cracks from a reverse side of a belt;
– peeling of separate ribs;
– razlokhmachivaniye of face edges of a belt;
– cross cracks in some ribs;
– destruction of separate ribs.
In the presence of any of defects replace a belt.
On release cars till 2001 the tension of poliklinovy belts is regulated manually, and since 2001 — automatically.
Tension of a belt it is checked by measuring Nippondenso or Burroughs devices. Measure a belt tension according to factory instructions on Nippondenso or Burroughs devices and compare the measured size to values of a tension for the new or being in the use belt.

       NOTE
The term "being in the use" in this manual belongs to a belt which was used more than 5 min.


Fig. 2.13. Measurement of a tension of a poliklinovy belt on release cars till 2001 pressing of a thumb of a hand a belt branch


In the absence of measuring devices it is possible to use a simple method which provides the acceptable belt tension accuracy. A hand thumb with moderate effort press a belt branch in the point which is equally spaced from the centers of pulleys (fig. 2.13) . Measure a deflection of a belt which has to be 6–6,5 mm at distance of pulleys of 180-280 mm and 12,5–13 mm at distance of pulleys of 305-405 mm between centers between centers.
