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.

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.

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.

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
