Timing Belt

TIMING BELT





1. Set crankshaft sprocket to TDC by aligning the sprocket with the arrow on the oil pump housing (2).




2. Set camshafts timing marks so that the exhaust camshaft sprocket (1) is a 1/2 notch (3) below the intake camshaft sprocket (2).

CAUTION: Ensure that the arrows on both camshaft sprockets are facing up.





3. Install timing belt. Starting at the crankshaft, go around the water pump sprocket, idler pulley, camshaft sprockets and then around the tensioner.
4. Move the exhaust camshaft sprocket (4) counterclockwise to align marks and take up belt slack.




5. Insert a 6 mm Allen wrench (3) into the hexagon opening located on the top plate (2) of the belt tensioner pulley. Rotate the top plate (2)COUNTERCLOCKWISE. The tensioner pulley will move against the belt and the tensioner setting notch (1) will eventually start to move clockwise. Watching the movement of the setting notch (1), continue rotating the top plate (2) counterclockwise until the setting notch is aligned with the spring tang (6). Using the allen wrench (3) to prevent the top plate (2) from moving, torque the tensioner lock bolt (4) to 25 Nm (220 in. lbs.). Setting notch (5) and spring tang (6) should remain aligned after lock bolt (4) is torqued.
6. Remove allen wrench (3) and torque wrench.

NOTE: Repositioning the crankshaft to the TDC position must be done only during the CLOCKWISE rotation movement. If TDC is missed, rotate a further two revolutions until TDC is achieved. DO NOT rotate crankshaft counterclockwise as this will make verification of proper tensioner setting impossible.





7. Rotate the crankshaft CLOCKWISE two complete revolutions manually for seating of the belt, until the crankshaft is repositioned at the TDC position. Verify that the camshaft (1) and crankshaft (2) timing marks are in proper position.




8. Check if the spring tang (1) is within the tolerance window (2). If the spring tang (1) is within the tolerance window (2), the installation process is complete and nothing further is required. If the spring tang (1) is not within the tolerance window (2), repeat Steps 5 through 7.




9. Install upper and lower front timing belt covers. Timing Cover - Installation.
10. Connect negative cable to battery.
