1. Apply a proper minimum quantity of engine oil to 

the following points.

• Camshaft end

• Insertion hole in V.V.T. sprocket (all over inside 

and outside surfaces)

• Threads and head of V.V.T. sprocket bolt

• Bearing surface of V.V.T. sprocket bolt

2. Install the V.V.T. sprocket onto the camshaft.
3. Make sure that the V.V.T. sprocket is installed all 

the way onto the camshaft. Holding the hexagonal 
portion of the camshaft with a wrench, check that 
the V.V.T. sprocket does not turn.

4. While holding the hexagonal portion of the 

camshaft with a wrench, tighten the V.V.T. 
sprocket bolt to 64.9 

± 5.9 N⋅m.

1. Place the timing chain such that the blue link that 

is away from the other two blue links of the chain 
is on the crankshaft side.

4. Install the chain onto the camshaft sprocket, 

aligning the blue link with the mark on the 
sprocket. 
When doing this, rotate the V.V.T. sprocket or the 
camshaft sprocket by a tooth or two and then 
align the blue link and the mark.

5. Ensure that all of the 3 pairs of the timing marks 

are aligned.

6. Install the chain guide and the tensioner lever.

>>D<< TIMING CHAIN TENSIONER 
INSTALLATION

1. While pressing in the plunger of the timing chain 

tensioner, insert the pin as illustrated to lock the 
plunger.

AK304935

2. Install the timing chain tensioner onto the cylinder 

block, timing chain Tensioner bolts to 8.4 

± 0.6

3. Remove the pin from the tensioner. Timing chain 

should be tensioned via the tensioner lever.

VALVE CLEARANCE MEASUREMENT

Measure the valve clearance as illustrated.

Set the special tool Crankshaft adapter (MB992000) 
to the crankshaft, and install the crankshaft pulley 
bolt and washer.

AK305645AB

Timing mark

CAUTION

The crankshaft should always be rotated clock-
wise.
1. Rotate the crankshaft clockwise until the mark on 

the camshaft sprocket is aligned with the mark on 
the upper surface of cylinder head. (Set the No. 1 
cylinder to TDC on the compression stroke.)

Intake

2. Now, the valve clearance (shown with an arrow) 

can be measured.

AK304936

3. Using a thickness gauge, measure the clearance 

between the cam base circle and the valve tappet.

Standard value (cold engine):

Intake valve 0.22 

± 0.04 mm

Exhaust valve 0.30 

± 0.04 mm

4. If the measured value does not conform to the 

standard value, record the measured value.

Timing mark

180˚

5. Rotate the crankshaft clockwise until the mating 

mark on the camshaft sprocket comes to the 
illustrated location. This will bring the No. 4 
cylinder to TDC on the compression stroke.

6. Measure the valve clearance at the location 

shown with an arrow.

7. If the measured value does not conform to the 

standard value, record the measured value.

8. Replace the valve tappet for the valve whose 

clearance is out of the standard value.
