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.

>>B<< 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.

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)

•

6. Tighten the crankshaft pulley centre bolt to the 

specified torque.

>>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.
