1. Turn the crankshaft pulley until the groove and the timing mark "0" on the timing chain cover are aligned.
2. Check that each timing mark on the camshaft timing gear and sprocket is aligned with each timing mark located on the No. 1 and No. 2 bearing caps as shown in the illustration.

   If not, turn the crankshaft pulley 1 revolution (360°) to align the timing marks as illustrated.

3. Place paint marks on the chain in alignment with the timing marks on the camshaft timing gear and camshaft timing sprocket.

1. While holding the No. 2 camshaft with a wrench, loosen the No. 2 camshaft timing set bolt.

HINT:

Depending on the air pressure, the camshaft timing gear assembly may turn to the advance side without applying force by hand. Also, if the pressure is difficult to apply because of air leakage from a path, the lock pin may be difficult to release.
