INSTALLATION SERVICE POINT

.

>>A<< CAMSHAFT SPROCKET INSTALLATION
1. Fit the camshaft sprocket to the front end of the camshaft.
2. While holding the camshaft sprocket with special tools 

MB990767 and MD998715, tighten the camshaft sprocket 
bolt.

Tightening torque: 88 

± 10 Nm (65 ± 7 ft-lb)

.

>>B<< CRANKSHAFT SENSING BLADE/CRANKSHAFT 
SPACER/CRANKSHAFT SPROCKET INSTALLATION
1. Clean the hole in the crankshaft sprocket.
2. Clean and degrease the mating surfaces of the crankshaft 

sprocket, sensing blade, and spacer

NOTE: Degreasing is necessary to prevent decrease in friction 
between the mating surface due to presence of oil.

.

>>C<< AUTO-TENSIONER INSTALLATION
If the auto-tensioner rod is fully extended, reset it as follows:
1. Clamp the auto-tensioner in the 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 the 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.

>>D<< TIMING BELT INSTALLATION

CAUTION

Do not turn the camshaft when the piston in No.1 cylinder 
is at the top dead center on the compression stroke. Doing 
so can cause the lifted valve to hit against the piston, 
resulting in damaging parts.
1. Install special tool MD998769 and the crankshaft pulley 

washer, and then tighten the crankshaft bolt.

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

timing mark on the oil pump case, and then rotate the 
sprocket three teeth counterclockwise.

3. Align the timing mark on the left bank camshaft sprocket 

with the timing mark on the rocker cover.

4. Align the timing mark on the right bank camshaft sprocket 

with the timing mark on the rocker cover.

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

timing mark on the oil pump case.

6. Install the timing belt on each sprocket and pulley in the 

following sequence. Do not leave the belt slack between 
each sprocket and pulley.

(1) Crankshaft sprocket
(2) Idler pulley
(3) Left bank camshaft sprocket
(4) Water pump pulley
(5) Right bank camshaft sprocket
(6) Tensioner pulley

7. Install special tool MD998767 to the tensioner pulley. While 

pushing the pulley lightly against the belt using the special 
tool, tighten the flange bolt.

Tightening torque: 48 

± 6 Nm (35 ± 4 ft-lb)

8. Check to see that the timing marks of all the sprockets are in 

a alignment.

9. Rotate the crankshaft a quarter turn counterclockwise. Then 

rotate it back clockwise to verify that all the timing marks are 
aligned.

10.Loosen the flange bolt securing the tensioner pulley, and 

then mount special tool MD998767 and a torque wrench on 
the tensioner pulley.

11.Torque it to 4.4 N

⋅m (39 in-lb) with the torque wrench.

12.While holding the tensioner pulley in position, tighten the 

flange bolt to the specified torque.

Tightening torque: 48 

± 6 Nm (35 ± 4 ft-lb)

13.Rotate the crankshaft two turns clockwise and leave it alone 

for approximately five minutes.

14.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 

 5.0 mm (0.15  0.20 inch)

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

previous steps (10) through (13) until proper belt tension is 
obtained.

>>E<< ENGINE SUPPORT BRACKET, RIGHT 
INSTALLATION
The mounting bolts of the right engine support bracket must be 
tightened in the order shown in the illustration.
