INSTALLATION SERVICE POINTS

>>A<< BALANCER TIMING BELT/BALANCER
TIMING BELT TENSIONER INSTALLATION

1. Ensure that the crankshaft balancer shaft drive

sprocket timing marks and balancer shaft
sprocket timing marks are aligned.

2. Install the balancer timing belt on the crankshaft

balancer shaft drive sprocket and balancer shaft
sprocket. There should be no slack on the tension
side.

3. Assemble and temporarily fix the centre of the

pulley of the balancer timing belt tensioner so that
it is at the top left from the centre of the
assembling bolt, and the pulley flange is at the
front-side of the engine.

4. Adjust the balancer timing belt tension.

ADJUSTMENT

CAUTION

When tightening the mounting bolts, ensure that
the tensioner does not rotate with the bolts.
Allowing it to rotate with the bolts can cause
excessive tension of the belt.

1. Lift with your fingers the balancer timing belt

tensioner in the direction of the arrow. Apply a
tensile torque of 3.0

±

0.4 N

⋅

m to the balancer

timing belt so the belt is tense without any
looseness. Tighten the assembling bolt to the
specified torque in this state. Then, fix the
balancer timing belt tensioner.

Tightening torque: 19

±

3 N

⋅

m

2. Turn the crankshaft clockwise two turns to set

No.1 cylinder to TDC of its compression stroke
and check that sprocket timing marks are aligned.

3. Apply a pressure of approximately 100 N at the

centre (arrow area) between the sprocket as
shown in the figure, then inspect whether the belt
deflection is within the standard value.

Standard value:

<When adjusting> 5

−

7 mm

<When replacing> 5

−

7 mm

4. If not within the standard value, adjust the belt

tension again.

INSTALLATION

1. Clean or degrease the crankshaft, the crankshaft

angle sensing blade, the crankshaft camshaft
drive sprocket and crankshaft pulley washer as
shown.
NOTE: Also clean the degreased surfaces.

2. Install the crankshaft angle sensing blade and

crankshaft camshaft drive sprocket in the
direction shown.

3. Place the larger chamfer side of the crankshaft

pulley washer in the direction shown in the Figure
and then assemble on the crankshaft pulley
centre bolt.

4. Apply a small of engine oil to the crankshaft pulley

centre bolt bearing surface and screw.

5. Use the following special tool as during removal to

hold the crankshaft camshaft drive sprocket.

•

Special spanner (MB991367)

•

>>D<< TIMING BELT TENSIONER 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
thoroughly compress.

(1) Slowly compress the timing belt tensioner

adjuster rod using a press or vice, then align
the set hole A of the rod with set hole B of the
timing belt tensioner adjuster cylinder.

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

NOTE: When replacing the timing belt
tensioner 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 bolt to the
specified torque. Do not remove the wire or pin
until the tension of the valve timing belt is
adjusted.

>>E<< TIMING BELT TENSIONER PULLEY
INSTALLATION

Temporarily tighten the timing belt tensioner pulley
as shown.

>>F<< VALVE TIMING BELT INSTALLATION

1. Align the timing marks on the camshaft sprocket,

crankshaft camshaft drive sprocket and engine oil
pump sprocket.

2. Adjust the timing mark of the engine oil pump

sprocket. Unplug the cylinder block plug. Insert a
bolt (M6, section width 10 mm, nominal length 45
mm) from the plug hole. If the bolt comes in
contact with the balancer shaft, turn the engine oil
sprocket one rotation. Re-adjust the timing mark
and then check to see that the bolt fits. Do not
remove the bolt until the valve timing belt is
assembled.

3. Incorporate the valve timing belt in the following

manner so that the tensile force of the belt is not
lax.
(1) Place the valve timing belt on the timing belt

tensioner pulley and crankshaft camshaft
driver sprocket and then support it with your
left hand so it does not slide.

(2) Place the valve timing belt on the engine oil

pump sprocket while pulling it with the right
hand.

(3) Place the valve timing belt on the timing belt

idler pulley.

CAUTION

Incorporate the valve timing belt. Then apply
reverse rotation (anti-clockwise rotation)
pressure to the camshaft sprocket. Re-check to
see that each timing mark is aligned while the
tension side of the belt is right.

(4) Place the valve timing belt on the camshaft

sprocket.
