Procedure

Important: Use the following steps in order to reset the timing chain tensioner assembly to the zero position.

 

1.Reset the timing chain tensioner assembly.

 

1.1.Insert the tensioner plunger assembly into the tensioner housing.

 

1.2.With the tensioner plunger fully extended, turn the complete assembly upside down on a bench or other flat surface.

 

1.3.With the plunger face against the workbench, press firmly on the bottom of the tensioner housing.

 

1.4.Compress the plunger until the plunger is seated flush in the tensioner.

 

2.Check the plunger to make sure that the plunger is out of the cylinder at the correct dimension. The correct dimension for the plunger to extend out of the cylinder is 1.7 mm (0.070 in) maximum.

 

3.Loosely install the tensioner assembly and bolts to the timing chain housing.

 

4.Install the timing chain tensioner shoe on the stud.

 

5.Apply hand pressure to the timing chain tensioner shoe until the locking tab seats in the groove in the stud.

 

Note: Do not over tighten the bolts retaining the component or failure to the component may occur.

 

6.Tighten the timing chain tensioner bolts.

 

Tighten

Tighten the bolts to 10 N.m (89 lb in).

Note: If the timing chain tensioner plunger is not released from the installation position, engine damage will occur when the engine is started.

 

7.Release the timing chain tensioner plunger.

 

7.1.Using a flat blade screwdriver, cotter pin remover, or a similar tool, press firmly against the face of the timing chain tensioner plunger.

 

Important: If the timing chain tensioner plunger cannot be depressed, the plunger is not properly reset and the procedure for resetting the timing chain tensioner should be repeated.

 

7.2.Depress the timing chain tensioner plunger until the plunger is bottomed out in the bore of the timing chain tensioner.

 

7.3.Release the tensioner plunger. The plunger should press firmly against the back of the timing chain tensioner shoe.
