Set No.1 cylinder to TDC (Top dead center) on compression stroke.
(1)
Turn the crankshaft pulley and align its groove with the timing mark of the timing chain cover.

(2)
Check that the TDC marks of the intake and exhaust CVVT sprockets are in straight line on the cylinder head surface as shown in the illustration. If not, turn the crankshaft by one revolution (360) more.

Do not turn the crankshaft pulley counterclockwise.
18.
Remove the crankshaft damper pulley (A).

Do not press the pulley or apply the excessive force to prevent the rubber part from being deformed.
There are two methods to hold the ring gear when removing the crankshaft damper pullly.

Install the SST (09231-3D100) to hold the ring gear after removing the service cover.
1.
Remove the air guard (A).

2.
Remove the two transaxle mounting bolts (A) and the service cover (B) on the bottom of the lower crankcase.

3.
Adjust the length of the holder (A) so that the grooves of the holder puts into the ring gears (B) at the closest position.
4.
Adjust the angle and length of the links (C) so that the two transaxle mounting bolts can be fastened into the original mounted holes.

5.
Install the SST using the two transaxle mounting bolts. Tighten the bolts and nuts of the holder and links securely.

19.
Remove the timing chain cover (A) by gently prying the gaps between the cylinder head and cylinder block.

Be careful not to damage the contact surfaces of cylinder block, cylinder head and timing chain cover.
