CAUTION

• When inserting special tool chain tension 

release bar (MB992103) into the timing chain 
case assembly inside, pay attention to the 
position of the valve timing chain to avoid 
damage to the valve timing chain and timing 
chain tension side guide. Do not insert the 
special tool MB992103 beyond its insertion 
guideline.

• If unlocking the timing chain tensioner is 

insufficient, the special tool MB992103 cannot 
be inserted to the insertion guideline. Do not 
insert the special tool MB992103 forcibly, fol-
low Step 2 again to unlock the timing chain 
tensioner and insert the special tool 
MB992103.

special tool chain tension release bar 
(MB992103) from the timing chain case assembly 
inside along the tension side of the valve timing 
chain until the insertion guide line aligns with the 
upper surface of the timing chain case assembly 
(A in the figure).

NOTE: With the timing chain tensioner unlocked, 
insert the special tool MB992103 along the ten-
sion side of the valve timing chain, according to 
the special tool MB992103 top shape. The special 
too MB992103 can be inserted smoothly to the 
position where the special tool MB992103 inser-
tion guideline aligns with the timing chain case 
assembly top surface, and the spread timing 
chain tension side guide can be hold.

4. With the special tool MB992103 inserted up to the 

insertion guide line, press the special tool 
MB992103 against the inlet side camshaft 
sprocket (B in the figure) and spread and hold the 
timing chain tension side guide (C in the figure).

5. Remove the precision flat-tipped screwdriver 

unlocking the timing chain tensioner.

6. Pull up the camshaft and camshaft sprocket 

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

timing chain which was put at removal with the 
paint mark of the exhaust side camshaft sprocket, 
and install the valve 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 MB992103 inserted into 

the timing chain case assembly inside.

1. Install the camshaft bearing front cap to the 

cylinder head, and temporarily tighten the 
camshaft bearing front cap to the specified torque 
in the order shown in the figure (1).

Tightening torque: 17 

± 3 N⋅m

2. Tighten the camshaft bearing front cap to the 

specified torque again in the order shown in the 
figure (2).

Tightening torque: 30 

± 2 N⋅m

3. After the camshaft bearing font 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.

>>G<< ROCKER COVER ASSEMBLY 
INSTALLATION

1. Remove the sealant from the joints between the 

rocker cover assembly and cylinder head and 
timing chain case assembly, and degrease the 
surface where the sealant is applied by white 
gasoline or the like.
