Removing Adjusting Disc
4. If valve clearance is not within the specifications, replace the adjusting disc. Depress the cam follower and lift out the disc as shown.
NOTE: To calculate the correct adjusting disc thickness, first determine the thickness of the old disc. Read the thickness in millimeters that is
etched on its underside, or measure it with a micrometer. The change in thickness required is the same as the difference between the measured
clearance and the specification given above. A thicker disc will reduce valve clearance. A thinner disc will increase valve clearance.
5. Install the correct adjusting disc. Lightly oil the contact surfaces. Depress the cam follower and install the disc the same way it was removed. The
etched disc thickness numbers should face down.
6. Using a socket wrench, rotate the crankshaft clockwise by hand for two complete turns, to ensure that the adjusting disc is properly seated, and
recheck the clearance.
7. Rotate the crankshaft by hand clockwise until the cam lobes for the next cylinder to be checked point up and away from the followers and repeat
the procedure on the valves for this cylinder. Procede in order through the remain cylinders.
8. Install the cylinder head cover with new gaskets.
