Adjustment
General Procedures
1. Remove the camshafts. For additional information, refer to
Camshaft
2. Use compressed air to remove the shims that require replacing.
Blow compressed air between the shim edge and bucket to
dislodge the shim.
3. Use the following formula to calculate the required shim thickness.
Original shim thickness + measured clearance - desired clearance =
required shim thickness.
4. Apply a light coat of engine oil to the replacement shim(s) and install.
5. Install the camshafts. For additional information, refer to

Check
General Procedures
1. Remove the left hand valve cover. For additional information, refer to
Valve Cover—LH
2. Remove the right hand valve cover. For additional information, refer to
Valve Cover—RH
3. CAUTIONS:
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.
Camshaft lobes must be 180 degrees away from each valve shim or
valve clearance measurement 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 Section
303-00 Engine System - General
Information
. Adjust the clearances as necessary. For additional
information, refer to
Valve Clearance Adjustment
