Timing Belt Removal Note

1.  Mark the timing belt rotation on the belt for proper reinstallation.

Caution
•  The following will damage the timing belt and shorten its life; forcefully twisting it, turning it inside out, or allowing oil or grease on it.
•  After removing the timing belt, do not move the crankshaft and/or camshaft pulley from this position because it can cause the valve and piston to contact and damage them.

3.  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.

4.  Install the timing belt.

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

6.  Tighten the tensioner lock bolt.

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

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

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