ENGINE -. Timing Belt
5) Align the timing mark of the crankshaft sprocket.
NOTE
Shift the timing mark of the crankshaft sprocket one
tooth in counterclockwise direction to facilitate belt
installation.
(2) Using bulldog clips, install the timing belt in the following
order with care not to allow the belt to slack.
(1) Exhaust camshaft sprocket (front bank side) -+ (2)
Intake camshaft sprocket (front bank side) + (3) Water
pump pulley + (4) Intake camshaft sprocket (rear bank
side) + (5) Exhaust camshaft sprocket + (6) Idler pulley
NOTE
Since the camshaft sprockets turn easily, secure them
with box wrenches to install the timing belt.
Caution
1. Be careful, the camshaft is turned by the reaction
of valve spring.
2. If the timing belt is reused, install it so that the
arrow marks made at removal are in the direction
of rotation.
(3) Turn the tensioner pulley so that its pin holes are located
above the center bolt. Then, press the tensioner pulley
against the timing belt and, at the same time, temporarily
tighten the center bolt.
(4) Check that the timing marks on all sprockets are aligned
properly.
(5) Remove the four clips.
(1) Rotate the crankshaft l/4 turn counterclockwise, then
rotate it clockwise until the timing marks are aligned.
(2) Loosen the center bolt on the tensioner pulley. Using
the special tool and torque wrench, apply tensioning
torque to the timing belt and, at the same time, tighten
the center bolt to specification.
Specified torque: 10 Nm (7 ft.lbs.)
[Timing belt tensioning torque]
Caution
When tightening the center bolt, make sure that the
tensioner pulley is not rotated together.
(3) Remove the set pin from the auto tensioner. At this time,
make sure that the set pin can be easily removed.
(4) Rotate the crankshaft two turns clockwise and leave it
as is for five minutes or more. Then, check again that
the set pin can be easily removed from, and installed
to, the auto tensioner.
