Timing Component Alignment Marks: Locations

VALVE TIMING BELT INSTALLATION





1. Align the timing marks on the camshaft sprocket, crankshaft camshaft drive sprocket and engine oil pump sprocket.





2. After aligning the timing marks of the engine oil pump sprocket, remove the cylinder block plug and insert a Phillips screw driver with a shaft diameter of 8 mm (0.31 inch) through the plug hole to check that the shaft of the screw driver can be inserted for 60 mm (2.36 inches) or more. If the screw driver makes contact with the balancer shaft and can be inserted for only 20 - 25 mm (0.79 - 0.98 inch), turn the engine oil pump sprocket for one round and align timing marks again to check that screw driver can be inserted for 60 mm or more. Do not take the screw driver out before completing installation of the valve timing belt.
3. Install the valve timing belt as follows:





1. Pass the valve timing belt around the crankshaft camshaft drive sprocket, the engine oil pump sprocket and the timing belt idler pulley in that order.





2. Pass the valve timing belt around the exhaust-side camshaft sprocket, and hold the valve timing belt with paper clamps.





3. Use two wrenches to align the timing mark on the rocker cover with that on the camshaft sprocket. Pass the valve timing belt around the inlet-side camshaft sprocket.





4. Hold the valve timing belt with paper clamps.
5. Pass the valve timing belt around the timing belt tensioner pulley.

CAUTION: Install the valve timing belt. Then apply reverse rotation (counterclockwise rotation) pressure to the cam shaft sprocket. Re-check to see that each timing mark is aligned while the tension side of the belt is tight.

6. Remove the two paper clamps.





4. Turn the timing belt tensioner in the direction shown using special tool MD998767 to apply tension to the valve timing belt. Then pre-tighten the timing belt tensioner pulley.
5. Check that the timing marks are aligned.
