Refit

1. Inspect camshaft timing belt for signs of uneven wear, splitting, or oil contamination. Renew belt if necessary.
2. Clean sealing area of head and camshaft, ensuring all traces of rubber are removed. DO NOT use a scraper as this may damage sealing surfaces.
3. Lubricate sealing surfaces of new oil seal with clean engine oil.

4. Using tool 18G 1604 fit NEW camshaft oil seal until seal is flush to face of mechanism.
5. Clean camshaft gear.

CAUTION: If the sintered gears have been subjected to prolonged oil contamination, they must be soaked in a solvent bath and thoroughly washed in clean solvent before refitment. Because of the porous construction of sintered material, oil impregnated in the gear will emerge and contaminate a new timing belt.
