Timing Belt: Service and Repair

REMOVAL AND INSTALLATION

REMOVAL SERVICE POINTS
[A] POWER STEERING OIL PUMP AND BRACKET ASSEMBLY REMOVAL
Remove the power steering oil pump and bracket assembly from the engine with the hose attached.

NOTE: Place the removed power steering oil pump in a place where it will not be a hindrance when removing and installing the timing belt, and tie it with a cord.

[B] TIMING BELT REMOVAL





1. Turn the crankshaft clockwise to align each timing mark and to set the No. 1 cylinder at compression top dead center.

CAUTION: The crankshaft should always be turned only clockwise.





2. Loosen the adjusting bolt.
3. Move the timing belt tensioner to the water pump side and temporarily tighten the adjusting bolt so that the tensioner does not return.
4. 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).

INSTALLATION SERVICE POINTS
]A[ TIMING BELT TENSIONER/TENSIONER SPRING/TIMING BELT INSTALLATION





1. Put the protrusion of the timing belt tensioner on the end (A) of the tensioner spring as shown.
2. Move the timing belt tensioner close to the water pump, and temporarily tighten the adjusting bolt.
3. Put a screwdriver in (c), push the protrusion (13) of the tensioner spring in the shown direction, and place it on the stopper (D) of the oil pump case.
4. Align each of the camshaft sprocket and the crankshaft sprocket timing marks.





5. 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) Camshaft sprocket
(3) 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.

]B[ TIMING BELT TENSION ADJUSTMENT
1. Initially loosen the adjusting bolt of the timing belt tensioner fixed to the water pump side by 1/2-1/4 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.
