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.
Standard value: 1.0 mm or less
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.
