Caution: Cover the paths with a shop rag to avoid oil splashes. Hint:

Depending on the air pressure, the camshaft timing gear will turn to the advance angle side without applying force by hand. Also, under the condition that the pressure is difficult to apply because of air leakage from the port, there may be the case that the lock pin is difficult to release.

4. Remove the flange bolt of the camshaft timing gear.

Notice:

• Be sure not to remove the other 4 bolts.
• When reusing the camshaft timing gear, release the straight pin lock first, then install the gear.
