CAUTION: Do not rotate camshaft or injection pump with timing belt removed. Ease timing belt from gears using fingers only. Metal levers may damage the belt and gears. Store a belt on its edge with a radius greater than 50 mm. DO NOT use a belt that has been twisted or bent double as this can fracture the reinforcing fibres. Do not use an oil or coolant contaminated belt. Cause of contamination must be rectified. Although the belt has a service life of 84,000 miles, (135,000 km) an existing belt should only be refitted if it has completed less than 42,000 miles, (65,000 km).
