TIMING BELT INSPECTION

PROCEDURE


  1. INSPECT TIMING BELT

    Note


    • Do not bend or twist the timing belt, and do not turn the timing belt inside out.

    • Do not allow the timing belt to come into contact with oil, water or steam.

    *b Oil
    *c Water

    1. Visually inspect the timing belt.

      If defects are present, perform the steps below.

    2. If there is premature parting:


      1. Check for proper installation.

      2. Check the timing belt cover gasket for damage and proper installation.

    3. If the timing belt teeth are cracked or damaged, check if either camshaft sub-assembly is locked.

    4. If there is noticeable wear or cracks on the timing belt face, check if there are nicks on the side of the No. 1 timing belt idler sub-assembly.

    5. If there is wear or damage on only one side of the timing belt, check the timing belt guide and the alignment of each pulley.

    6. If there is noticeable wear on the timing belt teeth, check the timing belt cover for damage, check that the gasket is installed correctly and check for foreign matter on the pulley teeth.

      If necessary, replace the timing belt.

  2. INSPECT NO. 1 TIMING BELT IDLER SUB-ASSEMBLY

      *1 Seal
      B003R2S Turn

      Check that the No. 1 timing belt idler sub-assembly turns smoothly by hand.

    2. Visually check that the seal portion of the No. 1 timing belt idler sub-assembly has no grease on it.

      Note


      • If there is oil, water or other foreign matter on the timing belt or a pulley, repair the leak.

      • Do not allow the timing belt and each pulley to come into contact with oil, water or steam.

      • Before installing the No. 1 idler pulley sub-assembly, be sure to clean each pulley with a cloth or equivalent.

      • When inspecting the No. 1 timing belt idler sub-assembly, do not remove it unless absolutely necessary.

  3. INSPECT IDLER TENSION SPRING


    1. B003PRAC02
      *a Free Length

      Measure the free length of the idler tension spring.

      Standard free length
      44.4 to 45.4 mm (1.75 to 1.79 in.)

      If the free length is not as specified, replace the idler tension spring.

    2. Measure the tension of the idler tension spring at the installed length.

      Standard tension
      53 to 59 N (5.40 to 6.02 kgf, 11.9 to 13.3 lbf) at 52.1 mm (2.05 in.)

      If the installed tension is not as specified, replace the idler tension spring.
