Removal & Installation: Inspection
- Inspect timing belt teeth for breaks, cracks or wear. Inspect belt for signs of oil contamination. When inspecting timing belt, do not bend less than a radius of 2.36" (6.0 mm). Replace belt if any fault is present.
- Inspect automatic belt tension adjuster oil seal for leaks. Slight trace of oil at adjuster rod oil seal does not indicate a problem. Inspect adjuster rod end for abnormal wear and scratches.
- Measure extension of adjuster rod beyond tensioner body. Holding tensioner with adjuster rod facing up, adjuster rod extension should be .204-.244" (5.2-6.2 mm). See Fig 1. Replace automatic timing belt tensioner assembly if adjuster rod extension is not as specified.
- Place automatic belt tension adjuster assembly in a press with adjuster rod facing up. Apply 66 lbs. (30 kg) of pressure on rod. If adjuster rod moves down easily, replace automatic timing belt tensioner assembly.
- Inspect automatic belt tension adjuster and idler pulleys for abnormal surface wear, oil leakage, rough rotation, noise and excessive play. Replace if any fault is present.
CAUTION:
DO NOT use a bench vise to compress adjuster rod. Always use a vertical type pressing tool to compress adjuster rod. It should take more than 3 minutes to compress adjuster rod.
