Checking the timing belt of the gas distribution mechanism

1. Remove the front timing cover (cm. «Replacing the timing belt»).

2. Inspect the condition of the timing belt. Replace the belt if, upon inspection, you find:

– traces of oil on any surface of a belt;

- signs of wear of the toothed surface, cracks, undercuts, folds and delamination of the fabric from the rubber;

– cracks, folds, depressions or bulges on the outer surface of the belt;

- Loosening or delamination on the end surfaces of the belt.

WARNING: A belt with traces of engine oil on any surface must be changed without fail, as the oil quickly destroys the rubber. Cause of oil on the belt (usually due to leakage of crankshaft and camshaft oil seals) must be eliminated immediately.

3. Check belt tension. A properly tensioned belt should rotate 90°with finger force 15–20 N (1.5–2 kgf), applied in the middle between the crankshaft and camshaft pulleys. Adjust belt tension if necessary (cm. «Replacing the timing belt»).

4. Install the parts in the reverse order of removal.
