CAMSHAFT SPROCKET ASSEMBLY (EXHAUST 
SIDE) INSTALLATION

CAUTION

• Be careful not to drop the camshaft bearing.
• When installing the camshaft and camshaft sprocket 

assembly (exhaust side), be careful not to let the cam-
shaft bearing which is installed to the front cam bearing 
deviate from its position.

1. When replacing the camshaft bearing, according to the 

identification mark of front camshaft bearing cap in the table 
below, select a camshaft bearing with the corresponding 
size. Note that the identification mark of camshaft bearing is 
stamped on the place shown in the figure.

2. In the same manner as removal, insert the precision 

flat-tipped screwdriver through the service hole of the timing 
chain case, press up the ratchet of timing chain tensioner to 
unlock, and hold the unlocked timing chain tensioner.
NOTE: Lightly press down the tail end of the precision 
flat-tipped screwdriver to press up the tip of the precision 
flat-tipped screwdriver inserted to the timing chain tensioner 
to unlock.

CAUTION

• When inserting special tool MB992103 into the timing 

chain case assembly, pay attention to the position of 
the timing chain to avoid damage to the timing chain 
and timing chain tension side guide. Do not insert the 
special tool beyond its insertion guideline.

• If unlocking the timing chain tensioner is insufficient, 

the special tool cannot be inserted to the insertion 
guideline. Do not insert the special tool forcibly, follow 
Step 2 again to unlock the timing chain tensioner and 
insert the special tool.

3. With the timing chain tensioner unlocked, insert special tool 

MB992103 inside the timing chain case assembly along the 
tension side of the timing chain until the insertion guide line 
aligns with the upper surface of the timing chain case 
assembly (Figure A). 
NOTE: With the timing chain tensioner unlocked, insert the 
special tool along the tension side of the timing chain, 
according to the special tool top shape. The special tool can 
be inserted smoothly to the position where the special tool 
insertion guideline aligns with the timing chain case assem-
bly top surface, and the spread timing chain tension side 
guide can be hold.

4. With the special tool inserted up to the insertion guide line, 

press the special tool against the intake side camshaft 
sprocket (Figure B) and spread and hold the timing chain 
tension side guide (Figure C).

5. Remove the flat-tipped precision screwdriver unlocking the 

timing chain tensioner.

6. Pull up the camshaft and camshaft sprocket assembly 

(exhaust side) mounting area of the timing chain (Figure D) 
to provide allowance for easy installation of the camshaft 
and camshaft sprocket assembly (exhaust side) to the 
timing chain.

CAUTION

When installing the camshaft and camshaft sprocket 
assembly (exhaust side), be careful not to let the camshaft 
bearing which is installed to the front cam bearing deviate 
from its position.

7. Align the exhaust side paint mark of the timing chain which 

was put at removal with the paint mark of the exhaust side 
camshaft sprocket, and install the timing chain to the 
camshaft sprocket.

8. Install the camshaft and camshaft sprocket assembly 

(exhaust side) to the cylinder head.

9. Remove the special tool inserted into the timing chain case 

assembly inside.

>>F<< FRONT CAMSHAFT BEARING CAP 
ASSEMBLY INSTALLATION

CAUTION

When the mounting bolts are tightened with the front cam-
shaft bearing cap tilted, the front camshaft bearing cap is 
damaged. Install the front camshaft bearing cap properly 
to the cylinder head and camshaft.
1. Install the front camshaft bearing cap to the cylinder head, 

and temporarily tighten the camshaft bearing front cap to the 
specified torque in the order of the figure (1).

Tightening torque: 17 

± 3 N⋅m (13 ± 2 ft-lb)

2. Tighten the front camshaft bearing cap again to the specified 

torque in the order of the figure (2).

Tightening torque: 30 

± 2 N⋅m (22 ± 1 ft-lb)

3. After the front camshaft bearing cap installation, check that 

the paint markings of the camshaft sprocket and the timing 
chain and the timing mark of the crankshaft pulley and the 
"T" mark position of ignition timing indicator are aligned 
respectively.
