  1. INSPECT FAN & GENERATOR V BELT


    1. A0137SC

      Visually check the belt for excessive wear, frayed cords etc.

      If any defect is found, replace the belt.

      Tech Tips

      Cracks on the rib side of a belt are considered acceptable. If the belt has chunks missing from the ribs, it should be replaced.

      Check the belt deflection by pressing on the belt at the points indicated by the arrow marks in the illustration.

      Deflection
      Item Specified Condition
      New belt 7 to 8 mm (0.28 to 0.31 in.)
      Used belt 9 to 11 mm (0.35 to 0.43 in.)

      If the belt deflection is not as specified, adjust it.

      Tech Tips


      • The most appropriate force for adjustment above is 98 N (10 kgf, 22 lbf).

      • "New belt" refers to a belt which has been used on a running engine less than 5 minutes.

      • "Used belt" refers to a belt which has been used on a running engine for 5 minutes or more.

      • After installing a belt, check that it fits properly in the ribbed grooves.

      • Check with your hand to confirm that the belt has not slipped out of the groove on the bottom of the pulley.

      • After installing a new belt, run the engine for about 5 minutes and recheck the belt tension.
