LH (No.1) Bank 2nd Timing Chain and Chain
Tensioner Removal and Installation

S6JB0B1406019

Removal

1) Remove engine assembly from vehicle. Refer to

“Engine Assembly Removal and Installation”.

2) Remove timing chain cover. Refer to “Timing Chain

Cover Removal and Installation”.

3) Turn crankshaft to meet the following condition.

• Key (1) on crankshaft positions as shown.
• Mark on idler sprocket No.2 (2) points the center

of crankshaft.

• The marks on sprockets (3) match with marks on

cylinder head.

4) Remove timing chain tensioner adjuster No.3 (1).

To remove it, slacken LH (No.1) bank 2nd timing
chain by turning intake camshaft (2)
counterclockwise a little while pushing back pad.

5) Remove LH (No.1) bank intake and exhaust

camshaft sprocket bolts.
To remove it, fit a spanner to hexagonal part (3) at
the center of camshaft to hold it stationary.

6) Remove LH (No.1) bank exhaust camshaft sprocket

(1).

CAUTION

!

Removing sprocket (1) from camshaft (2) may
cause cam to turn, resulting in damage to
valve and piston. To prevent this, when
removing sprocket, hold camshaft stationary
by using a spanner at its hexagonal part.

7) Remove LH (No.1) bank intake camshaft sprocket.
8) Remove LH (No.1) bank 2nd timing chain.
