<<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.

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.
