TIMING BELT REMOVAL

1.

Turn the crankshaft clockwise (right turn) to align each
timing mark and to set the No. 1 cylinder at compression
top dead centre.

Caution
The crankshaft should always be turned only
clockwise.

2.

Loosen the adjusting bolt.

3.

Set a screwdriver to the timing belt tensioner and press
it fully back in the direction of the arrow.

4.

Provisionally tighten the adjusting bolt.

5.

Remove the timing belt.

Caution
If the timing belt is to be re-used, use chalk to mark
the flat side of the belt with an arrow indicating the
direction of rotation (right turn).

3.

Align each of the camshaft sprocket and the crankshaft
sprocket timing marks.

4.

Install the timing belt in the following order, while making
sure that the tension side of the belt is not slackened.
(1) Crankshaft sprocket
(2) Water pump sprocket
(3) Camshaft sprocket
(4) Tensioner pulley

Caution
After installing the timing belt, apply force to turn
the camshaft sprocket in the reverse direction, and
recheck to be sure that the belt is fully tensioned and
that each timing mark is in the proper position.

TIMING BELT TENSION ADJUSTMENT

1.

Loosen the adjusting bolt of the temporarily secured timing
belt tensioner by 1/4 – 1/2 turn, and use the force of
the tensioner spring to apply tension to the belt.

2.

Turn the crankshaft in the proper rotation direction (right
turn) for two rotations, and recheck to be sure that the
timing marks on each sprocket are aligned.

Caution
As the purpose of this procedure is to apply the proper
amount of tension to the tension side of the timing
belt by using the cam driving torque, turn the
crankshaft only by the amount given above. Be sure
not to turn the crankshaft in the opposite direction
(left turn).

3.

After checking to be sure that no belt teeth in the section
marked with A are lifted up and that the teeth in each
sprocket are engaged, secure the tensioner pulley.
