<<B>> CYLINDER NO. 1 COMPRESSION TOP 
DEAD CENTER SETTING

CAUTION

Never turn the crankshaft counterclockwise.
1. Turn the crankshaft clockwise so that the camshaft sprocket 

timing marks become horizontal to the cylinder head upper 
surface, and set the cylinder No. 1 to the top dead center of 
compression. At this time, check that the crankshaft pulley 
timing mark is in the 0-degree position of the ignition timing 
indicator of the timing chain case assembly. 

2. Put paint marks on both the camshaft sprocket and timing 

chain at the position of camshaft sprocket timing chain 
mating mark (circular hole).

.

<<C>> CAMSHAFT AND CAMSHAFT SPROCKET 
ASSEMBLY (EXHAUST SIDE) REMOVAL 
PREPARATORY OPERATION

1. Insert a precision flat-tipped screwdriver through the service 

hole of the timing chain case, press up the timing chain 
tensioner ratchet to unlock, and keep the timing chain 
tensioner with that state.
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 inside, pay attention to the posi-
tion 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 1 again to unlock the timing chain tensioner and 
insert the special tool.

2. 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 guide line aligns with the timing chain case assem-
bly top surface (Figure B), and the spread timing chain ten-
sion side guide can be held (Figure C).

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

press the special tool against the intake side camshaft 
sprocket and spread and hold the timing chain tension side 
guide.

4. Remove the flat-tipped precision screwdriver unlocking the 

timing chain tensioner.

CAUTION

The timing chain may snag on by other parts. After sag-
ging the timing chain, never rotate the crankshaft.
5. With the timing chain tension side guide spread, hook the 

special tool over the hexagon part of the camshaft on the 
exhaust side, and turn the camshaft clockwise to apply slack 
to the timing chain between the camshaft sprockets. 

.

<<D>> FRONT CAMSHAFT BEARING CAP 
ASSEMBLY REMOVAL

CAUTION

Be careful not to drop the camshaft bearing.
Loosen the mounting bolts of front camshaft bearing cap in the 
order of number shown in the figure, and remove the front cam-
shaft bearing cap assembly.
