Timing Belt: Adjustments

TENSION ADJUSTMENT




(1) Check all the timing marks for alignment.
(2) Set the timing belt first on the crankshaft sprocket and then, while keeping the tension side of belt tight, set on the camshaft sprocket.

Caution: When the belt is reused, install the belt observing the arrow mark having been put on its back at the time of removal.

(3) Apply counter-clockwise force to the camshaft sprocket to give a tension to the belt on tension side and make sure that all timing marks are lined up.
(4) Install the crankshaft pulley temporarily.

NOTE: The above step (4) is necessary to prevent the belt from coming off when the crankshaft is turned.

(5) Loosen the slot side tensioner bolt.




(6) Tighten the slot side tensioner bolt and then the pivot side tensioner bolt.

Caution: If the pivot side bolt is tightened first, the tensioner will turn with the bolt, causing overtension.

(7) Turn the crankshaft clockwise.

Caution: Turn the crankshaft smoothly at a constant speed. Never turn it counter-clockwise. Do not apply any other force than spring force to give tension to the belt.

(8) Loosen the pivot side bolt, and then the slot side bolt.
(9) Tighten the slot side bolt, and then the pivot side bolt.




(10) Hold the tensioner and timing belt by hand and give the belt a slight thumb pressure at a point level with the tensioner center. Make sure that the belt cog crest comes as deep as about 1/4 of the width of slot side bolt head.
