REMOVAL SERVICE POINT

.

<<A>> TIMING BELT REMOVAL

CAUTION

The crankshaft should always be turned in the forward 
direction only.
1. Turn the crankshaft in the forward direction (to the right) to 

align the camshaft sprocket timing marks.

CAUTION

If the timing belt is to be re-used, use chalk to mark (on its 
flat side) an arrow indicating the clockwise direction.
2. Loosen the tension pulley fixing bolt.
3. Move the tension pulley to the water pump side, and then 

remove the timing belt.

INSTALLATION SERVICE POINTS

.

>>A<< AUTO-TENSIONER INSTALLATION
1. Apply 98 

− 196 N (22 − 44 pound) force to the pushrod of the 

auto-tensioner by pressing it against a metal object (such as 
the engine block) and measure the movement of the 
pushrod.

Standard value: Within 1 mm (0.04 inch)
A: Length when it is free (not pressed)
B: Length when it is pressed
A 

− B: Movement

2. If it is outside the standard value, replace the auto-tensioner.

CAUTION

Never compress the pushrod too fast, or it may be dam-
aged.
3. Use a press or vise to gently compress the auto-tensioner 

pushrod until pin hole A of the pushrod and pin hole B of the 
tensioner cylinder are aligned.

4. When the holes are aligned, insert the set pin.

NOTE: When replacing the auto-tensioner with a new part, 
the pin will be in the auto-tensioner.

5. Install the auto-tensioner to the engine.

.

>>B<< TIMING BELT INSTALLATION
1. Align the timing marks on the camshaft sprocket, crankshaft 

sprocket and oil pump sprocket.

2. After aligning the timing mark on the oil pump sprocket, 

remove the cylinder block plug and insert a Phillips) head 8 
mm (0.3 inch) screwdriver. Check to be sure that the 
screwdriver goes in 60 mm (2.4 inches) or more. If the 
screwdriver will only go in 20 

− 25 mm (0.8 − 1.0 inch) 

before striking the counterbalance shaft, turn the sprocket 
once, realign the timing marks and check that the 
screwdriver goes in 60 mm (2.4 inches) or more.
The screwdriver should not be taken out until the timing belt 
is installed.

CAUTION

If the timing belt is re-used, install so that the arrow 
marked on it at time of removal is pointing in the clockwise 
direction.
3. Install the belt to the crankshaft sprocket, oil pump sprocket 

and camshaft sprocket in that order, so that there is no 
slackness in the belt tension.

4. Set the tension pulley so that the pin holes are at the bottom, 

press the tension pulley lightly against the timing belt, and 
then provisionally tighten the fixing bolt.

5. Adjust the timing belt tension.

CAUTION

Do not use a spanner or the similar tool to turn special tool 
MD998738. Otherwise, the auto-tensioner set pin may be 
broken. Turn special tool MD998738 by hand only.
1. Remove the rubber plug from the rear of the timing belt 

cover assembly. Then screw in special tool MD998738 by 
hand until the tensioner arm is touching the auto-tensioner 
pushrod.

2. After turning the crankshaft 1/4 of a revolution in the 

counterclockwise direction, turn it in the clockwise direction 
until the timing marks are aligned.

CAUTION

When tightening the fixing bolt, make sure that the tension 
pulley does not turn with the bolt.
3. Loosen the tension pulley fixing bolt, and then use special 

tool MD998767 and a torque wrench to tighten the fixing bolt 
to the specified torque while applying tension to the timing 
belt.

Timing belt tension torque: 3.5 N

⋅m (31 in-lb)

Tightening torque:48 

± 6 N⋅m (36 ± 4 ft-lb)

4. Remove the set pin that has been inserted into the 

auto-tensioner, and then remove special tool MD998767.

5. Turn the crankshaft two revolutions clockwise so that the 

timing marks are aligned. After leaving it for 15 minutes, 
measure the amount of protrusion of the auto-tensioner.

Standard value (A): 3.8 

− 4.5 mm (0.15 − 0.18 inch)

6. If the amount of protrusion is outside the standard value, 

repeat steps (1) through (5).

7. Check again to be sure that the timing marks of each 

sprocket are aligned.
