How to align the timing marks for the camshaft of the Changan 474 engine?

[AbigailRose]

Rotate the crankshaft vibration damper pulley clockwise so that the notch on the crankshaft vibration damper pulley aligns with the mark on the lower timing belt cover. Use a crankshaft timing gear wrench to turn the crankshaft vibration damper pulley clockwise. Loosen the fixing nut, release the timing tensioner, and remove the timing belt. Use an exhaust timing gear fixing tool to adjust the position of the exhaust camshaft. Rotate the intake/exhaust timing gears fully to the right so that the mark on the exhaust timing gear aligns with the yellow mark on the timing belt.
