TIMING BELT INSTALLATION

SERVICE POINTS OF INSTALLATION

31. Installation of crankshaft sprocket " B."






Install the crankshaft sprocket "B" as shown while paying attention to its direction.

30. Installation of spacer.






(1) Apply a thin coat of engine oil to the outer circumference of the spacer.
(2) Install the spacer with the chamfered end facing the oil seal.

NOTE: If the spacer is installed adversely, the oil seal may be damaged, resulting in the oil leaks.

28. Installation of timing belt " B."






(1) Ensure that crankshaft sprocket "B" timing mark and the silent shaft sprocket timing mark are aligned.
(2) Fit timing belt "B" over crankshaft sprocket "B" and the silent shaft sprocket. Ensure that there is no slack in the belt.

- Adjustment of timing belt "B" tension.






(1) Temporarily fix the timing belt "B" tensioner such that the center of the tensioner pulley is to the left and above the center of the installation bolt, and temporarily attach the tensioner pulley so that the flange is toward the front of the engine.






(2) Holding the timing belt "B" tensioner up with your finger in the direction of the arrow, place pressure on the timing belt so that the tension side of the belt is taut. Now tighten the bolt to fix the tensioner.

Caution: When tightening the bolt, ensure that the tensioner pulley shaft does not rotate with the bolt. Allowing it to rotate with the bolt can cause excessive tension on the belt.






(3) To ensure that the tension is correct, depress the belt (point A) with a finger. It not, adjust.

Standard value: 5-7 mm (0.20-0.28 in.).

26. Installation of flange.






Install the flange in correct direction as shown.

22. Installation of tensioner spring/21. tensioner spacer/2O. timing belt tensioner.






(1) Install the tensioner spring, tensioner spacer and timing belt tensioner.
(2) Place the upper end of the tensioner spring against the water pump body.






(3) Move tensioner fully toward water pump and temporarily secure tensioner.

19. Installation of timing belt.






(1) Ensure that the timing marks of the camshaft sprocket, the crankshaft sprocket, and the oil pump sprocket are all aligned.






(2) When aligning the timing mark of the oil pump sprocket, remove the plug of the cylinder block; then insert the shaft of a cross-tip (+) screwdriver with a shaft diameter of 8 mm (0.31 in.) into the plug hole and check to be sure that the screwdriver's shaft can be inserted at least 60 mm (2.36 in.). Do not remove the screwdriver until the timing belt Is completely attached. If the screwdriver's shaft can be inserted only to a depth of about 20 to 25 mm (0.79 to 0.98 in.) because it contacts the silent shaft, turn the sprocket by one rotation and align the timing mark once again; then check again to be sure that the screwdriver's shaft can be inserted at least 60 mm (2.36 in.).






(3) Install timing belt. While making sure that tension side of belt is not slackened, install timing belt onto crankshaft sprocket, oil pump sprocket and camshaft sprocket in that order.

Caution: If the timing belt is reused, install so that the arrow marked on it at the time of removal is pointing in the clockwise direction.

- Adjustment of timing belt tension.






(1) Loosen tensioner mounting nut. By so doing, tensioner will be moved by spring and will apply tension to belt.
(2) Recheck to be sure that each sprocket's timing mark is correct.






(3) Turn the crankshaft clockwise by two teeth of the camshaft sprocket.

Caution: As the purpose of this procedure is to apply the proper amount of tension on the timing belt, be sure not to rotate the crankshaft counterclockwise or place pressure on the belt to check the amount of tension.






(4 Apply force on tensioner toward turning direction, (in the direction of the arrow) such that no portion of the belt raises out in portion A, place the belt on the camshaft sprocket such that the belt sprocket teeth are fully engaged.
(5) Tighten the tensioner installation bolt and tensioner spacer in that order.

Caution: If the tensioner spacer is tightened first, the tensioner will rotate with it and belt tension be thrown out of adjustment. Always tighten the bolt first.






(6) Check to see that the clearance between the outside of the belt and the cover are within the standard value by grasping the tension side (between the camshaft sprocket and oil pump sprocket) of the center part of the timing belt between the thumb and index finger.

Standard value: 12 mm (0.40 in.).

14. Installation of timing belt front lower cover/12. timing belt front upper cover.






Note that the timing belt lower and upper cover attaching bolts differ in size from one place to another.
