DRIVE BELT ON-VEHICLE INSPECTION

PROCEDURE


  1. INSPECT V-RIBBED BELT


    1. A00YA7S

      Check the V-ribbed belt for wear, cracks or other signs of damage.

      If any of the following defects is found, replace the V-ribbed belt:


      • The belt is cracked.

      • The belt is worn out to the extent that the cords are exposed.

      • The belt has chunks missing from the ribs.

    2. A00Y81YC03
      *a Correct
      *b Incorrect

      Check that the V-ribbed belt fits properly in the ribbed grooves.

      Tech Tips

      Check with your hand to confirm that the V-ribbed belt has not slipped out of the groove on the bottom of the pulley. If it has slipped out, replace the V-ribbed belt. Install a new V-ribbed belt correctly.

    3. A00Y52ZC02
      *a Deflection
      *b Tension

      Inspect the V-ribbed belt deflection and tension.

      Deflection
      Item Specified Condition
      New belt 7.0 to 8.2 mm (0.276 to 0.322 in.)
      Used belt 7.6 to 10.0 mm (0.300 to 0.393 in.)
      Tension
      Item Specified Condition
      New belt 700 to 800 N (70 to 80 kgf, 158 to 179 lbf)
      Used belt 550 to 750 N (56 to 76 kgf, 124 to 168 lbf)

      Tech Tips


      • When inspecting the V-ribbed belt deflection, apply 98 N (10 kgf, 22 lbf) tensile force to it.

      • Check the V-ribbed belt deflection at the specified point.

      • When installing a new V-ribbed belt, adjust its tension to the specified value.

      • When inspecting a V-ribbed belt which has been used for over 5 minutes, apply the used V-ribbed belt specifications.

      • When reinstalling a V-ribbed belt which has been used for over 5 minutes, adjust its deflection and tension to the intermediate values of each used belt specification.

      • V-ribbed belt tension and deflection should be checked after 2 revolutions of engine cranking.

      • When using a V-ribbed belt tension gauge, confirm its accuracy by using a master gauge first.
