CAUTION
Never turn the crankshaft anti-clockwise.
1. Turn the crankshaft clockwise, align each timing
mark to set No.1 cylinder to TDC of its
compression stroke.
2. Remove the timing belt under cover rubber plug
and then set special tool adjusting bolt
(MD998738).
3. Screw in the special tool with hands until it
contacts the timing belt tensioner arm.
CAUTION
The special tool can be gradually installed at a
rate of a 30 degree turn per second. If it is
screwed in all at once, the timing belt tensioner
adjuster rod will not easily retract and the special
tool may bend.
4. Gradually screw in the special tool and then align
the timing belt tensioner adjuster rod set hole A
with the timing belt tensioner adjuster cylinder set
hole B.
5. Insert a wire or pin in the set hole aligned.
CAUTION
To reuse the valve timing belt, draw an arrow
indicating the rotating direction (clockwise) on
the back of the belt using chalk, etc.
6. After removal of the special tool, loosen the timing
belt tensioner pulley mounting bolts and remove
the valve timing belt.

TENSIONER INSTALLATION
1. Ensure that the crankshaft balancer shaft drive
sprocket timing marks and balancer shaft
sprocket timing marks are aligned.
2. Install the balancer timing belt on the crankshaft
balancer shaft drive sprocket and balancer shaft
sprocket. There should be no slack on the tension
side.
3. Assemble and temporarily fix the centre of the
pulley of the balancer timing belt tensioner so that
it is at the top left from the centre of the
assembling bolt, and the pulley flange is at the
front-side of the engine.
4. Adjust the balancer timing belt tension.
