TIMING BELT

Replace the belt if any of the following conditions 
exist:
1. Hardening of rubber backing.

Back side should be glossy without resilience and 
leave no indent when pressed with fingernail.

2. Cracks on rubber back. 
3. Cracks or peeling of canvas.
4. Cracks at bottom of ribs.
5. Cracks on belt sides.

6. Abnormal wear of belt sides. Normal wear is 

indicated if the sides are sharp as if cut by a knife. 
Abnormal wear is indicated if the sides are 
ragged.

7. Abnormal wear on teeth. 

Initial stage:
Canvas worn (fluffy canvas fibers, rubbery 
texture gone, white discoloration, canvas 
texture indistinct)
Final stage:
Canvas worn, exposing rubber (tooth width 
reduced)

8. Missing tooth.

AUTO-TENSIONER

1. Check for oil leaks. If oil leaks are evident, replace 

the auto-tensioner.

2. Check the rod end for wear or damage and 

replace the auto-tensioner if necessary.

4. Press the rod with a force of 98 to 196 N and 

measure the movement of the rod.
If the measured value is out of the standard value, 
replace the auto-tensioner.

VALVE CLEARANCE ADJUSTMENT

Perform the adjustment of the valve clearance in the 
following procedure.
1. Remove the rocker cover.

CAUTION

Rotate the crankshaft clockwise at any time.
2. Rotate crankshaft clockwise and then align the 

timing mark on the camshaft sprocket with the 
timing mark on the cylinder head. (Place No.1 
cylinder on the top dead center of compression 
stroke.)

3. Measure the valve clearance marked with arrows 

shown in the figure.
White arrow mark: When No.1 cylinder is on the 
top dead center of compression stroke.
Black arrow mark: When No.4 cylinder is on the 
top dead center of compression stroke.

4. Using a thickness gauge, adjust the clearance 

between the valve shaft end and the adjusting 
screw.

Standard value (in cold state):

Intake side: 0.11 mm
Exhaust side: 0.20 mm
NOTE: After the engine assembly is installed on 
the vehicle, check the valve clearance again in 
the engine warm-up state. Adjust if necessary.

5. Hold the adjusting screw not rotating through a 

driver and then tighten the rock nut.

6. Rotate the crankshaft one time clockwise and 

then align the timing mark with the timing mark on 
the crankshaft sprocket. (Place No.4 cylinder on 
the top dead center of compression stroke.)

7. Adjust the valve clearance for the rest of the 

valves.

8. Install the rocker cover.

CAUTION

• The fuel injectors are classified into A, B and 

C by the injection quantity. When replacing 
one of fuel injectors, use a same identification 
mark fuel injector as the other fuel injectors.

• When replacing the fuel injectors of all 

cylinders, use the same identification mark 
fuel injectors.

Install a new gasket is positioned as shown in the 
illustration.

>>B<< INJECTORS INSTALLATION

CAUTION

Use care not to let engine oil enter the delivery 
pipe.
1. Apply clean engine oil to the O-ring.
2. Insert the injector into the delivery pipe.
3. Make sure the injector rotates smoothly.

If not, remove the injector to check the O-ring for 
damage, and replace the O-ring if necessary. 
Then, reinstall the injector and check that it 
rotates smoothly.
