General procedures

Valve Clearance Adjustment (12.29.48)

1. Remove the left-hand valve cover.



2. Remove the right-hand valve cover.
Valve Cover RH (12.29.44)


3. Turn the crankshaft pulley clockwise to position the relevent camshaft lobe 180 degrees to
the shim being replaced.


4. Remove the camshaft bearing cap.

5. Install the special tool.

•

Making sure the legs of the tool are in contact with the edge of the valve bucket,

compress the bucket.

6. Use compressed air to remove the shims that require replacing.

•

Blow compressed air between the shim edge and bucket to dislodge the shim.

7. Use the following formula to calculate the required shim thickness.

•

Original shim thickness + measured clearance - desired clearance = required shim

www.

thickness.

8. Apply a light coat of engine oil to the replacement shim(s) and install.


9. Install the left-hand valve cover.



10. Install the right-hand valve cover.
Valve Cover RH (12.29.44)

Valve Clearance Check (12.29.47)

1. Remove the left-hand valve cover. For additional information, refer to .



2. Remove the right-hand valve cover. For additional information, refer to .



3.

CAUTION: Rotating the crankshaft in a counterclockwise direction may cause

engine damage. Crankshaft journals are directionally machined. Rotating the
crankshaft counterclockwise Can raise burrs on bearing surfaces, reducing engine life.

CAUTION: Camshaft lobes must be 180 degrees away from each valve tappet or

valve clearance will be incorrect.

Rotate the engine clockwise to position the camshaft lobe away from the shim surface.


4. Using the feeler gauge set, measure the clearance between the camshaft and the shim
surface. Record and check the readings. For additional information, refer to <<303-00>>.
Adjust the clearances as necessary. For additional information, refer to.

5. Install the right-hand valve cover. For additional information, refer to .



6. Install the left-hand valve cover. For additional information, refer to .
