>>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.

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.
