Timing Belt: Inspection

  1. Inspect timing belt for wear on rounded edges of drive teeth. Inspect belt for signs of oil contamination. Replace belt if it is damaged or contaminated.
  2. Inspect belt automatic tensioner oil seals for leaks. Slight trace of oil at rod oil seal does not indicate a problem. Inspect rod ends for abnormal wear and scratches.
  3. Measure extension of rod beyond tensioner body. Holding tensioner with rod facing up, rod extension should be .204-.244" (5.2-6.2 mm). See Fig 1. Replace automatic tensioner if rod extension is not as specified.
    4. CAUTION: Always use a vertical type pressing tool to compress automatic tensioner rod. DO NOT use a bench vise to compress rod. It may take more than 3 minutes to compress the automatic tensioner rod.
  4. Place automatic tensioner in a press with tensioner rod facing up. Apply 66 lbs. (294 N) of pressure on rod. If rod moves down easily, replace automatic tensioner.
  5. Inspect automatic tensioner and idler pulleys for worn bearings or lubricant leaks. Replace as necessary.
