Refer to: Accessory Drive Belt (303-05 Accessory Drive - 2.5L Duratec-HE (122kW/165PS) - MI4, Removal and Installation). 2. Refer to: Valve Cover (303-01 Engine - 2.5L Duratec-HE (122kW/165PS) - MI4, Removal and Installation). 3. CAUTION: Only rotate the crankshaft clockwise. NOTE: Before removing the camshafts, measure the clearance of each valve at base circle, with the lobe pointed away from the tappet. Failure to measure all clearances prior to removing the camshafts will necessitate repeated removal and installation and wasted labor time. NOTE: If the valve clearance is less than 0.2mm, adjust the valves to the maximum clearance. Rotate the crankshaft until the cam pair of the cylinder to be adjusted are pointing upwards. Using a suitable feeler gauge, measure the valve clearance. E70936 4. Make a note of each cylinder number with the corresponding valve clearance. 5. Compare the measured valve clearance(s) with the specifications. Refer to: Specifications (303-01 Engine - 2.5L Duratec-HE (122kW/165PS) - MI4, Specifications). 6. NOTE: Only carry out the following steps when the valve clearance(s) require adjustment. 7. WARNING: Only rotate the crankshaft clockwise. Turn the crankshaft until no. 1 piston is at about 45° before TDC. E131739 8. CAUTION: The Camshaft Alignment Plate is for camshaft alignment only. Using this tool to prevent engine rotation can result in engine damage. NOTE: The camshaft timing slots are offset. If the Camshaft Alignment Plate cannot be installed, rotate the crankshaft one complete
