(Engine oil)

1. Check that the nominal length of each cylinder

head bolt meets the limit. If it exceeds the limit,
replace the bolts with a new one.

Limit (A): 103.2 mm

2. Apply a small amount of engine oil to the thread of

the bolts and to the washers.

3. Use special tool cylinder head bolt wrench

(MB991653) to tighten the cylinder head bolts in
the following procedures.
(1) Tighten the bolts to 49

± 2 N⋅m in the order

shown.

(2) Loosen the bolts fully in the reverse sequence

to that shown.

(3) Tighten the bolts to 20

± 2 N⋅m in the order

shown.

(4) Apply a paint mark to the heads of the cylinder

head bolts and cylinder head, then tighten 90
degree angle as shown.

CAUTION

• The bolt is not tightening sufficiently if the

tightening angle is less than a 90 degree
angle.

• If the tightening angle exceeds the standard

specification, remove the bolt and start over
from step 1.

(5) Tighten in a 90 degree angle as shown in the

instructions of the figure, then check to see
that the paint mark on the head of the cylinder
head bolts and the paint mark on the cylinder
head is on a linear line.

REMOVAL SERVICE POINT
<<A>> VALVE TIMING BELT REMOVAL

CAUTION

Be sure to use special tool crankshaft sprocket
spacer (MD998769) when installing the crank-
shaft pulley centre bolt to the crankshaft. If the
bolt is installed directly to the crankshaft, the tip
of the bolt and the thread of the crankshaft may
be damaged.

1. Set the special tool, the crankshaft pulley washer

and the crankshaft pulley centre bolt to the
crankshaft camshaft drive sprocket.

CAUTION

Never turn the crankshaft anti-clockwise.

4. Screw in the special tool with hands until it

contacts the timing belt tensioner arm.

CAUTION

The special tool can be gradually installed at a
rate of a 30 degree turn per second. If it is
screwed in all at once, the timing belt tensioner
adjuster rod will not easily retract and the special
tool may bend.

5. Gradually screw in the special tool. Then align the

timing belt tensioner adjuster rod set hole with the
timing belt tensioner adjustor cylinder set hole,
and insert a wire or a pin.

CAUTION

To reuse the valve timing belt, draw an arrow
indicating the rotating direction (clockwise) on
the back of the belt using chalk, etc.
6. After removal of the special tool, loosen the timing

belt tensioner pulley mounting bolts and remove
the valve timing belt.

ADJUSTER INSTALLATION

1. Set according to the following procedures when

the timing belt tensioner adjuster rod is fully
extended.

CAUTION

If the compression is too fast the procedure may
damage the rod. Make a point to slowly and thor-
oughly compress.

(2) Insert a wire or pin in the set hole aligned.

NOTE: . When replacing the timing belt ten-
sioner adjuster with new parts, the timing belt
tensioner adjuster is set with a pin.

2. Install the timing belt tensioner adjuster to the

engine and then tighten the mounting bolts to the
specified torque. Do not remove the wire or pin
until the tension of the valve timing belt is
adjusted.
