Camshaft timing belt

CAMSHAFT TIMING BELT

Service repair no - 12.65.18

NOTE: Two types of timing belt tensioner are fitted, type A is a manual tensioner, type B is an automatic tensioner. The tensioners and their timing belts are not interchangeable.

CAUTION: Timing belt must be replaced if cylinder head is to be removed or new timing gears, tensioner or coolant pump are to be fitted. Timing belts must be stored and handled with care. Always store a timing belt on its edge with a bend radius greater than 50 mm. Do not use a timing belt that has been twisted or bent double as this will damage the reinforcing fibres. Do not use a timing belt if debris other than belt dust is found in timing cover. Do not use a timing belt if partial engine seizure has occurred. Do not use a timing belt if belt mileage exceeds 48,000 miles (77,000 km). Do not use an oil or coolant contaminated belt.

NOTE: The cause of contamination MUST be rectified.
