  11. INSPECT DRIVE BELT


    1. A01CHS3E02
      Text in Illustration
      *1 Fan Pulley
      *2 Generator
      *3 Crankshaft Pulley

      Check the fan and generator V belt deflection.

      Tech Tips


      • The specified deflection values per belt are shown in the following table.

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

      Deflection
      Item Specified Condition
      New belt 10.5 to 12.5 mm (0.413 to 0.492 in.)
      Used belt 12.5 to 16.0 mm (0.492 to 0.630 in.)

      Note


      • Check the V belt deflection at the specified point.

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