1st Timing Chain and Chain Tensioner Removal
and Installation

S6JB0B1406022

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) For reinstallation of timing chain, align 8 timing

marks as shown in figure by turning crankshaft.

4) Remove LH (No.1) bank 2nd timing chain. Refer to

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

5) Remove the following parts referring to “1st Timing

Chain and Chain Tensioner Components”.
• Timing chain guide No.1 and No.2.
• Timing chain tensioner.
• Timing chain tensioner adjuster.
• Idler sprocket No.1 and 1st timing chain.
• Idler sprocket No.2 and sprocket shaft.

6) Remove RH (No.2) bank 1st timing chain intake

camshaft sprocket bolt. To remove it, fit a spanner to
hexagonal part (3) at the center of camshaft (2) to
hold it stationary.

7) Remove RH (No.2) bank 1st timing chain intake

camshaft sprocket (1).

8) Remove 1st timing chain crankshaft sprocket.

Installation

1) Check timing pulley key (1) of crankshaft is on

specified position as shown in figure.

2) Install 1st timing chain crankshaft sprocket (2) to

crankshaft as shown in figure.

3) Check timing mark on RH (No.2) bank intake

camshaft as shown in figure.

4) Install RH (No.2) bank 1st timing chain intake

camshaft sprocket (1) noting the following points.
• The sprocket should be set in such way that its

timing marks (4) can be seen.

• Camshaft (2) should be held stationary by using a

spanner at its hexagonal parts (3) as shown in
figure.

Tightening torque
RH (No.2) bank 1st timing chain intake
camshaft sprocket bolt (a): 80 N·m (8.0 kgf-m,
58.0 lb-ft)

5) Install timing chain tensioner (1) as shown in figure.

Tightening torque
Timing chain tensioner nut (b): 25 N·m (2.5 kgf-
m, 18.0 lb-ft)

6) Install 1st timing chain by aligning match marks (2)

on RH silver plate (1) of 1st timing chain and RH
(No.2) bank 1st timing chain intake camshaft
sprocket (3).

7) Apply oil to bush of idler sprocket No.2.
8) Install idler sprocket No.2 and sprocket shaft.
9) Install idler sprocket No.2 by aligning match marks

(2) on LH silver plate (1) of 1st timing chain.

10) Install crankshaft sprocket by aligning match marks

(2) on yellow plate (1) of 1st timing chain and
crankshaft timing sprocket.
To install it, fit a spanner to hexagonal part at the
center of RH (No.2) bank intake camshaft to turn a
little.

CAUTION

!

Do not turn camshaft more than necessary. If
turned excessively, valve and piston may get
damaged.

11) Apply oil to bearing of idler sprocket No.1.

12) Install idler sprocket No.1.

Tightening torque
Idler sprocket No.1 bolt (c): 55 N·m (5.5 kgf-m,
40.0 lb-ft)

13) With latch of tensioner adjuster No.1 returned and

plunger (1) pushed back into body, insert stopper (3)
into latch (2) and body.
After inserting it, check to make sure that plunger (1)
will not come out.

14) Install timing chain tensioner adjuster No.1 (1).

Tightening torque
Timing chain tensioner adjuster No.1 bolt (a): 11
N·m (1.1 kgf-m, 8.0 lb-ft)

15) Pull out stopper (3) from adjuster No.1 (1).

16) Install timing chain guide No.1 (2) and No.2 (1).

Tightening torque
Timing chain guide No.1 and No.2 bolt (a): 9 N·m
(0.9 kgf-m, 6.5 lb-ft)
