NOTE: When the timing belt is installed into the 
crankshaft sprocket, install the timing belt after 
sliding the crankshaft sprocket to around the key 
end. (Pay attention to the notch on the crankshaft 
sprocket not to be damaged at the timing belt 
installation.) And then, install the crankshaft 
sprocket in position.

3. Confirm the timing marks on each sprocket are in 

position.

CAUTION

Check that the glow plugs, glow plug mounting 
threads and plug seating surfaces of cylinder 
head are dry.
4. When installing the glow plug, screw in one thread 

or more with fingers and then tighten with a tool.

5. Tighten the glow plugs to 9.0 

± 1.0 N⋅m.

6. Using the special tool Angle gauge (MB991614), 

tighten the glow plug to a further 30

° to 40°.

7. Install a glow plug plate to the glow plug, and then 

tighten them to the specified torque of 1.8 

± 0.2 

N

⋅m.

8. Pull out the set pin of an auto tensioner.
9. Turn the crankshaft twice in a clockwise direction 

and measure the protrusion height of the auto 
tensioner.

Standard value: 2.3 

 7.6 mm

10.Confirm the timing marks on each sprocket are in 

position.

>>K<< COVER INSTALLATION

AK500654AB

1. Clean both mating surfaces of cover and cylinder 

block.

2. Apply a 2.3 

± 1.0 mm wide bead of sealant to the 

cylinder block.

Specified sealant:
Three bond 1217G or equivalent

AK500657AB

3. Coat the bolt with sealant, then install and tighten 

it.

Specified sealant:
Three bond 2310 or equivalent

INSPECTION

TIMING BELTS
The timing belts must be checked closely. Should the 
following defects be evident, replace the belt with a 
new one.

AK202794

1. Hardened back surface rubber.

TIMING BELT

ENGINE OVERHAUL

Glossy, non-elastic, and so hard that no mark is 
produced even when scratched by fingernails.

Cracks

Peeling of canvas

Cracks in tooth roots

AB

Cracks in sides

2. Cracked back surface rubber.
3. Cracked or separated canvas.
4. Cracked tooth bottom.
5. Cracked side.

AK202795

Rounded edge

Abnormal wear 
(Fluffy strand)

AB

6. Abnormal wear on side.

NOTE: Normal belt should have clear-cut sides as 
if cut by a sharp knife.

AK202796

Missing 
Tooth

Canvas lost and 
rubber exposed

AB

7. Abnormal wear in teeth.
Initial stage:

Canvas on load side tooth flank worn (Fluffy canvas 
fibers, rubber gone and color changed to white, and 
unclear canvas texture)
Last stage:
Canvas on load side tooth flank worn down and rub-
ber exposed (tooth width reduced)
8. Missing tooth.

AUTO-TENSIONER
1. Check the auto-tensioner for leaks from the 

sealed sections.
Replace it if leaky.

2. Check the rod end for wear and other damage.

Replace the auto-tensioner if the rod is badly 
worn or damaged.

AK500737AB

14.5 mm

3. Measure the extension length of the rod.

If it is not within the standard value range, replace 
the auto-tensioner.

Standard value: 14.5 mm

4. Measure the amount of the retraction when the 

rod is pressed with the force of 100 

− 200 N. If it 

deviates from the standard value, replace the auto 
tensioner.

Standard value: within 1.0 mm

AIR BLEEDING PROCEDURE OF AUTO-
TENSIONER
When the auto tensioner is not kept with its rod 
upward, or when the set pin having 

φ2 mm is pulled 

out before the installation to the engine, carry out the 
air bleeding as follows.

TIMING BELT

ENGINE OVERHAUL

11B-28

CAUTION

• If the lateral type press is used, the appropri-

ate air bleeding is not carried out. Always use 
longitudinal type press.

• To prevent damage to the auto tensioner, do 

not apply the load of 5,000 N or more.

AK801061AB

100

 – 

200 N

5 mm

To prevent damage to the auto tensioner, do 
not push down the rod from the cylinder end 
plane by 0.5 mm or less.

1. Set the auto tensioner to the longitudinal type 

press as shown in the illustration.

2. Slowly press down the rod, two or three times, to 

the cylinder end plane.

3. When the rod protrusion has approximately 5 mm, 

apply the load of 100 

− 200 N. Check whether the 

auto tensioner has sufficient stiffness.

4. If the auto tensioner does not have sufficient 

stiffness, replace the auto tensioner.

5. Slowly pressing down the rod, insert the set pin 

having 

φ2mm through the hole to fix the auto 

tensioner.

CAUTION

To prevent the air from being incorporated, keep 
the auto tensioner with its rod upward after the 
air bleeding. Do not keep the auto tensioner with 
60

° or more tilt.
