Timing Belt: Adjustments

TIMING BELT ADJUSTMENT




1. Align the crankshaft pulley timing groove with the mark on the oil pump.




2. Make sure that the camshaft pulley timing mark is aligned with the upper surface of the cylinder head and the dowel pin is in the up position.




3. Install the belt in the following order.
1) Crankshaft timing pulley
2) Camshaft pulley
3) Coolant pump pulley
4) Tension pulley
4. Insert a hex wrench into the tension pulley hexagonal hole. Rotate the pulley anticlockwise to tension the belt. Hold the pulley stationary and temporarily tighten the bolt.
5. Turn the crankshaft two complete counterclockwise revolutions and align the crankshaft timing pulley groove with the mark on the oil pump.
6. Loosen the tension pulley bolt.
7. Insert a hex wrench into the tension pulley hexagonal hole. Rotate the pulley anticlockwise to tension the belt. Hold the pulley stationary and tighten the bolt to the specified torque.

Torque N.m (lb.ft.) 50 (37)







8. Move the crankshaft back to about 50° BTDC and then back to TDC of Number 4 cylinder. Align the crankshaft pulley timing groove with the mark on the oil pump. Make sure that the camshaft pulley timing mark is aligned with the upper surface of the cylinder head and the dowel pin is in the up position.




9. Measure the deflection by the procedure as shown in the Figure.

Deflection N.m (in.) 16-20 (0.708-0.078)

10. If the measurement value is not within specified, repeat the procedures from step 4.
