Timing Belt, Tensioner, Tensioner Spring Assembly Note

Caution
•  Overtensioning of the timing belt can cause breakage of the belt and the camshaft.

1.  Align the timing marks as shown in the figure.

2.  Verify that the fuel injection pump attaching bolts and nuts are tightened to the specified torque. This must be done to prevent overtensioning of the timing belt after it has been installed.

3.  Install the timing belt.

4.  Install the tensioner, tensioner spring, and the lock bolt.

5.  Tighten the tensioner lock bolt.

6.  Turn the crankshaft clockwise twice, and align the timing marks. If they are not aligned, remove the timing belt and repeat from Step 1.

7.  Loosen the tensioner lock bolt to apply tension to the belt. Do not apply tension other than that of the tensioner spring.

8.  Tighten the tensioner lock bolt. Be sure the tensioner does not move together with the bolt rotation.


Timing Belt Cover Assembly Note

1.  Tighten the timing belt cover bolts in the order shown in the figure.
