>>H<< OIL PUMP SPROCKET INSTALLATION
1. Insert a Phillips head screwdriver [shank diameter 8 mm 

(0.3 inch)] through the plug hole on the left side of the 
cylinder block to block the left counterbalance shaft.

2. Install the oil pump sprocket.
3. Apply a thin coat of engine oil to the seating surface of the 

nut.

4. Tighten the nut to the specified torque.

Tightening torque: 54 

± 5 N⋅m (40 ± 4 ft-lb)

.

>>I<< AUTO-TENSIONER INSTALLATION
If the auto-tensioner rod is fully extended, reset it as follows:
1. Clamp the auto-tensioner in a vise with soft jaws.

2. Push in the rod little by little with the vise until the set hole A 

in the rod is aligned with hole B in the cylinder.

3. Insert a wire [1.4 mm (0.055 inch) in diameter] into the set 

holes. This auto-tensioner setting wire will be used during 
timing belt alignment.

4. Unclamp the auto-tensioner from the vise.

CAUTION

Leave the wire installed in the auto-tensioner.
5. Install the auto-tensioner onto the front case and tighten to 

the specified torque.

Tightening torque: 23 

± 3 N⋅m (17 ± 2 ft-lb)

>>J<< TENSIONER PULLEY INSTALLATION
Set the tensioner pulley so that the holes for attaching a wrench 
are positioned as shown in the illustration.

>>K<< TIMING BELT INSTALLATION
1. Align the timing mark on the camshaft sprocket with the 

timing mark on the rocker cover.

2. Align the timing mark on the crankshaft sprocket with the 

timing mark on the front case.

3. Align the timing mark on oil pump sprocket with its mating 

mark.

4. Remove the plug on the cylinder block and insert a Phillips 

head screwdriver [shank diameter 8 mm (0.3 inch)] through 
the hole.
If it can be inserted as deep as 60 mm (2.4 inches) or more, 
the timing marks are correctly aligned.
if the inserted depth is only 20 to 25 mm (0.8 to 0.9 inch), 
turn the oil pump sprocket one turn and realign the timing 
marks, then check to ensure that the screwdriver can be 
inserted 60 mm (2.4 inches) or more. Keep the screwdriver 
inserted until the timing belt is completely installed.

5. Set special tool MD998738 as shown and screw it in up to 

the position where the wire inserted in the auto-tensioner 
can be moved lightly.

6. Install the timing belt on the crankshaft sprocket, oil pump 

sprocket, idler pulley, camshaft sprocket, and tensioner 
pulley in that order.

7. Lift up the tensioner pulley in the direction of the arrow and 

tighten the center bolt. 

8. Check that all timing marks are aligned.
9. Remove the screwdriver inserted in step 5 and install the 

plug.

10.Turn the crankshaft a quarter turn counterclockwise. Then, 

turn it clockwise until the timing marks are aligned again.

11.Install special tool MD998767, socket wrench and torque 

wrench, onto the tensioner pulley, and loosen the tensioner 
pulley center bolt.
NOTE: Use a torque wrench that can measure 0 to 5.0 N

⋅

m 

(0 

−

 44 in-lb).

12.Torque to 3.5 N

⋅m (31 in-lb) with the torque wrench.

13.Holding the tensioner pulley with special tool MD998767 

and torque wrench, tighten the center bolt to specification.

Tightening torque: 48 

± 6 N⋅m (35 ± 4 ft-lb)

14.The wire inserted at the auto-tensioner installation is pulled 

out and then the special tool MD998738 is removed by 
hand.

15.Give two clockwise turns to the crankshaft. Wait for 15 

minutes, then proceed with the following inspection steps.

16.Check to see whether the metal wire (inserted when the 

auto-tensioner was installed) can be removed without any 
resistance.
If the metal wire can be removed without any resistance, it 
means that the belt has a proper tension. Therefore, remove 
the metal wire. In this condition, check that the rod 
protrusion of the auto-tensioner is within the standard value.

Standard value: 3.8 

− 4.5 mm (0.15 − 0.17 inch)

17.If the metal wire offers resistance when removed, repeat the 

previous steps 10 through 15 until the standard value is 
obtained as measured by the rod projection of the 
auto-tensioner rod.

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.
